Bizarre-Looking Fungus Improves Cognition & Immunity, New Research Suggests

The AHA! Team — Mon, 08 Sep 2025 05:25:40 +0000

Lori Alton via NaturalHealth365 – Gastroesophageal reflux disease, or acid reflux as it is often known, is one of the most common health complaints among adults. So much so that medications to treat the symptoms make up the third highest-selling class of drugs in the United States. Of all the medicinal mushrooms, tremella mushrooms are undoubtedly the strangest looking, with a translucent white color and a complicated-looking arrangement of frills and folds that causes them to resemble reef coral. Botanically labeled as tremella fuciformis, tremella mushrooms are commonly known by nicknames that range from the charming (snow mushrooms) to the creepy (witches’ butter). You may also hear them referred to as snow fungus, white fungus, and white jelly mushrooms. But these intriguing fungi are so much more than visual oddities. Valued as adaptogens and immune system boosters in traditional Chinese medicine for thousands of years, tremella mushrooms are now impressing contemporary researchers. A clinical study in the Journal of Medicinal Foods concluded that tremella extracts can help protect brain cells and improve cognition and memory in patients with cognitive impairment. You won’t want to miss out on the far-reaching “head-to-toe” benefits of these fascinating fungi. Tremella mushrooms help reverse memory loss and slow the progression of neurodegenerative diseases In a double-blind, controlled trial involving 75 individuals with subjective cognitive impairment, the researchers set out to assess the efficacy and safety of tremella. They found that participants who received between 600 and 1,200 mg a day of tremella for eight weeks experienced greater memory and executive function improvements than those in the control group. The team concluded that tremella could be safely used to improve memory and enhance cognition. A 2022 study published in Nutrients explored tremella mushrooms’ ability to act against oxidative stress and brain inflammation that contribute to neurodegenerative diseases. The researchers found that tremella mushrooms contain polysaccharides with anti-amyloidogenic properties (this forbidding-sounding word means that they act against the buildup of harmful amyloid-beta plaque implicated in Alzheimer’s disease). They also have antioxidant and anti-apoptotic effects, meaning they can prevent the death of brain cells. One specific tremella polysaccharide, TL04, was found in animal studies to confer protective effects through the mitochondrial pathway. The team concluded that polysaccharides in tremella are “promising neuroprotective agents” with “enormous potential” to inhibit the progression of neurodegenerative conditions such as Alzheimer’s disease, Parkinson’s disease, Huntingdon’s disease, and ALS. Tremella combats inflammatory intestinal diseases by enhancing immunity and gut microbe diversity In a 2021 study published in Frontiers in Immunology, researchers concluded that polysaccharides in tremella mushrooms have the potential to alleviate inflammation and tissue damage caused by ulcerative colitis. These beneficial carbohydrates also support the health of the gut microbiome by increasing microbial diversity and renewing populations of beneficial bacteria such as Lactobacillus. As these bacteria’s metabolites help regulate the immune system, this also supports immune defenses. Studies have shown that polysaccharides can directly activate immune system components such as macrophages and T-cells. While more study is needed, the implications are promising. Promote and protect skin health, radiance, and hydration Tremella mushrooms contain potent antioxidants that reduce skin inflammation and help to protect against photoaging (another word for wrinkles and age spots induced by the harmful ultraviolet rays in sunlight). In addition, their polysaccharides have humectant properties, meaning they can draw moisture into the skin. In a 2021 study published in the International Journal of Immunopathology and Pharmacology, a 0.05 percent formulation of tremella polysaccharides performed as well in hydrating skin as a 0.02 percent formulation of hyaluronic acid – and it accomplished this at only 14 percent of the cost! Researchers endorsed tremella polysaccharides for rehydrating the skin and protecting and repairing the skin barrier. Tremella polysaccharides also help to increase the production of collagen, a protein that promotes skin firmness and elasticity (the sought-after qualities that give skin a youthful appearance). Access benefits through diet, supplements, or topical application Whole tremella mushrooms are available fresh or dried in markets and health food stores. Dried mushrooms should be soaked for an hour to rehydrate before using in recipes. While fresh tremella mushrooms are perfectly edible and nutritious – packed with dietary fiber, plant-based protein, essential vitamins, and minerals – they have a gelatinous texture that some people find off-putting. That said, their flavor is subtle and mild, and they blend in well with soups, stews, stir-fries, and casseroles. Powdered tremella is also available as a supplement. Use a reputable vendor, and choose an organic product certified by the NSF (National Sanitation Foundation) or USP (United States Pharmacopeia). You can also find tremella in topical serums, facial masks, and lotions. Before supplementing with tremella, you may want to get the “thumbs-up” from your holistic healthcare provider. Unsurprisingly, tremella mushrooms have also exhibited effects against cancer, diabetes, fatty liver disease, and obesity. While much of their potential is still unexplored, their obvious benefits are causing them to emerge as an exciting natural intervention against chronic and degenerative diseases.

Cells ‘Vomit’ Waste to Promote Healing, Mouse Study Reveals

The AHA! Team — Wed, 03 Sep 2025 05:36:33 +0000

Washington University in St. Louis via Newswise – Newly discovered purging process in gastric cells hints at how injury recovery can go wrong – The researchers dubbed the new purging process “cathartocytosis,” combining Greek root words meaning cellular cleansing. When injured, cells have well-regulated responses to promote healing. These include a long-studied self-destruction process that cleans up dead and damaged cells as well as a more recently identified phenomenon that helps older cells revert to what appears to be a younger state to help grow back healthy tissue. Now, a new study in mice led by researchers at Washington University School of Medicine in St. Louis and the Baylor College of Medicine reveals a previously unknown cellular purging process that may help injured cells revert to a stem cell-like state more rapidly. The investigators dubbed this newly discovered response cathartocytosis, taking from Greek root words that mean cellular cleansing. Published online in the journal Cell Reports, the study used a mouse model of stomach injury to provide new insights into how cells heal, or fail to heal, in response to damage, such as from an infection or inflammatory disease. “After an injury, the cell’s job is to repair that injury. But the cell’s mature cellular machinery for doing its normal job gets in the way,” said first author Jeffrey W. Brown, MD, PhD, an assistant professor of medicine in the Division of Gastroenterology at WashU Medicine. “So, this cellular cleanse is a quick way of getting rid of that machinery so it can rapidly become a small, primitive cell capable of proliferating and repairing the injury. We identified this process in the GI tract, but we suspect it is relevant in other tissues as well.” Jettisoning of waste Brown likened the process to a “vomiting” or jettisoning of waste that essentially adds a shortcut, helping the cell declutter and focus on regrowing healthy tissues faster than it would be able to if it could only perform a gradual, controlled degradation of waste. As with many shortcuts, this one has potential downsides: According to the investigators, cathartocytosis is fast but messy, which may help shed light on how injury responses can go wrong, especially in the setting of chronic injury. For example, ongoing cathartocytosis in response to an infection is a sign of chronic inflammation and recurring cell damage that is a breeding ground for cancer. In fact, the festering mess of ejected cellular waste that results from all that cathartocytosis may also be a way to identify or track cancer, according to the researchers. A novel cellular process The researchers identified cathartocytosis within an important regenerative injury response called paligenosis, which was first described in 2018 by the current study’s senior author, Jason C. Mills, MD, PhD. Now at the Baylor College of Medicine, Mills began this work while he was a faculty member in the Division of Gastroenterology at WashU Medicine and Brown was a postdoctoral researcher in his lab. In paligenosis, injured cells shift away from their normal roles and undergo a reprogramming process to an immature state, behaving like rapidly dividing stem cells, as happens during development. Originally, the researchers assumed the decluttering of cellular machinery in preparation for this reprogramming happens entirely inside cellular compartments called lysosomes, where waste is digested in a slow and contained process. From the start, though, the researchers noticed debris outside the cells. They initially dismissed this as unimportant, but the more external waste they saw in their early studies, the more Brown began to suspect that something deliberate was going on. He utilized a model of mouse stomach injury that triggered the reprogramming of mature cells to a stem cell state all at once, making it obvious that the “vomiting” response — now happening in all the stomach cells simultaneously — was a feature of paligenosis, not a bug. In other words, the vomiting process was not just an accidental spill here and there but a newly identified, standard way cells behaved in response to injury. Although they discovered cathartocytosis happening during paligenosis, the researchers said cells could potentially use cathartocytosis to jettison waste in other, more worrisome situations, like giving mature cells that ability to start to act like cancer cells. The downside to downsizing While the newly discovered cathartocytosis process may help injured cells proceed through paligenosis and regenerate healthy tissue more rapidly, the tradeoff comes in the form of additional waste products that could fuel inflammatory states, making chronic injuries harder to resolve and correlating with increased risk of cancer development. “In these gastric cells, paligenosis — reversion to a stem cell state for healing — is a risky process, especially now that we’ve identified the potentially inflammatory downsizing of cathartocytosis within it,” Mills said. “These cells in the stomach are long-lived, and aging cells acquire mutations. If many older mutated cells revert to stem cell states in an effort to repair an injury — and injuries also often fuel inflammation, such as during an infection — there’s an increased risk of acquiring, perpetuating and expanding harmful mutations that lead to cancer as those stem cells multiply.” More research is needed, but the authors suspect that cathartocytosis could play a role in perpetuating injury and inflammation in Helicobacter pylori infections in the gut. H. pylori is a type of bacteria known to infect and damage the stomach, causing ulcers and increasing the risk of stomach cancer. The findings also could point to new treatment strategies for stomach cancer and perhaps other GI cancers. Brown and WashU Medicine collaborator Koushik K. Das, MD, an associate professor of medicine, have developed an antibody that binds to parts of the cellular waste ejected during cathartocytosis, providing a way to detect when this process may be happening, especially in large quantities. In this way, cathartocytosis might be used as a marker of precancerous states that could allow for early detection and treatment. “If we have a better understanding of this process, we could develop ways to help encourage the healing response and perhaps, in the context of chronic injury, block the damaged cells undergoing chronic cathartocytosis from contributing to cancer formation,” Brown said.

MRI Drugs Leave Toxic Heavy Metal Residue in the Brain

The AHA! Team — Wed, 27 Aug 2025 05:49:18 +0000

Lori Alton via NaturalHealth365 – MRIs help doctors see inside your body, but new findings have raised red flags. Medical experts want more research on health risks – especially how these metal-based contrast agents might build up in your body long after the scan. Many MRI procedures involve getting a contrast injection to improve the clarity of the images. The problem is that some patients with multiple MRIs report thinking problems afterward. These symptoms increasingly point to gadolinium, a metal used in contrast agents that may be more dangerous than we thought. New research shows it can stay in your body for years, even with healthy kidneys. What’s particularly concerning is that gadolinium might damage your cells and even your DNA. Scientific studies raise serious brain health concerns A study showed a correlation between intravenous gadolinium-based contrast agents and deposits of gadolinium found in neural tissues. Results were published online in Radiology, with lead author Robert McDonald, MD, PhD, Mayo Clinic, noting that some of the administered doses of contrast agent deposited in neural tissues were surprising. Patients who have undergone routine MRIs, such as Marcie Jacobs, later reported a loss of cognitive abilities. After having memory and other brain function issues following several years of routine MRIs for breast cancer detection, Ms. Jacobs ended up on disability. Also in the journal Radiology, Dr. Emanuel Kanal, University of Pittsburgh Medical Center, along with Michael Tweedle at Ohio State University, wrote that current studies “called into question” the “safety of at least some” of the agents. While the two did not call for an end to the use of these agents, they did call for increased caution in using these drugs. Are you being offered these MRI drugs? About a third of all MRIs in America still use gadolinium-based contrast agents, even as questions linger about their long-term safety. The FDA has tightened regulations rather than banning the most problematic agents outright – taking a different approach than European regulators who pulled Omniscan and Magnevist from their markets back in 2018. This safety debate isn’t new. Back in 2007, the U.S. Food and Drug Administration (FDA) first required warnings after research linked certain agents to nephrogenic systemic fibrosis, a serious condition causing tissue hardening, particularly in kidney patients who struggle to clear the metal from their bodies. Despite two FDA reviewers pushing for an outright ban on high-risk agents, the agency opted for stronger warnings instead. By 2010, they recommended against using Omniscan, Magnevist, and Optimark for patients with kidney problems. In 2018, warnings expanded to include gadolinium retention risks even for people with healthy kidneys. These days, doctors typically reach for newer macrocyclic agents, which hold their gadolinium more securely and seem less likely to release it into body tissues. However, the debate continues about whether these regulatory steps go far enough to protect patients. Gadolinium brain deposits spark ongoing safety debate Brain scans after certain contrast-enhanced MRIs show gadolinium sticking around – a discovery that’s raised eyebrows across medicine even without clear proof of harm. The findings haven’t definitively shown these metal deposits cause problems, but they’ve certainly got doctors thinking twice. GE Healthcare insists its research shows no evidence of harm from these brain deposits. Bayer has been working with outside researchers to get to the bottom of things. Both companies have settled their share of lawsuits, including some involving deaths. Back in 2010, Bayer reached a settlement with a California man who claimed Bayer’s product Magnevist gave him nephrogenic systemic fibrosis – a rare but serious condition. The health dangers continue to be a hot topic of debate. Research points in different directions – some studies raise red flags while others find no smoking gun. Doctors now find themselves weighing benefits against possible risks, especially when their patients already have kidney problems. The risk to MRI patients continues Doctors now check kidney function before giving patients contrast agents, but that might not solve the problem. We’re seeing gadolinium deposits showing up even in people with healthy kidneys, sometimes months or years after their MRIs. Researchers are worried about finding these metal traces in brain tissue at much higher levels than anyone thought possible. We don’t know yet how this might affect someone’s brain function or overall health over the long haul. The data simply isn’t there. This puts radiologists in a tough spot. These contrast agents help spot tumors, inflammation, and blood vessel problems that might otherwise go undetected. That’s incredibly valuable – but at what risk? Some hospitals have started switching to newer gadolinium compounds like the macrocyclic agents, which seem to hold onto their gadolinium better than older ones like Omniscan and Magnevist. Others are cutting doses to the bare minimum or skipping contrast altogether when possible. For patients needing multiple MRIs throughout their lives, the risk increases with each scan. Many are now asking for contrast-free procedures or looking for facilities that use the newer, possibly safer agents. Until we know more, the smart move seems to use the least risky contrast agents only when absolutely necessary. Meanwhile, researchers keep studying what happens to these metal deposits in the body over time. One thing’s for sure – we haven’t heard the last word on gadolinium safety.

Do I Need an Epileptologist?

The AHA! Team — Mon, 18 Aug 2025 05:37:03 +0000

Morgan deBlecourt via Duke Health – An epileptologist is a neurologist who specializes in caring for people with epilepsy. Epileptologists have completed an additional one to two years of subspecialty training in epilepsy care. Most people with epilepsy can see a primary care doctor or general neurologist to manage their seizures. However, you may need more advanced care if your seizures are not under control, if you have certain medical issues, or if you want a second opinion. An epileptologist is a neurologist who specializes in caring for people with epilepsy. Epileptologists have completed an additional one to two years of subspecialty training in epilepsy care. When to See an Epileptologist To confirm your epilepsy diagnosis If your seizures are not under control after three months of care by your primary care physician or after one year of care by a general neurologist If your seizures are not under control despite trying two or three different medications If you are experiencing unwanted side effects from medications If you have other medical conditions or considerations that affect or are affected by epilepsy If you are pregnant or want to become pregnant Seek Care at an Epilepsy Center “An epileptologist typically works in a designated epilepsy center, which is capable of evaluating people whose seizures are not under adequate control. An epilepsy center provides a very comprehensive approach to care,” said Duke epileptologist Aatif Husain, MD. An epilepsy center is staffed by specialists who use sophisticated testing to pinpoint your diagnosis, offer the latest treatments, address possible side effects of medications, recommend surgical options if appropriate, and help you manage the social and emotional aspects of epilepsy. “Advances over the past decade have enabled more personalized epilepsy care,” said Duke epileptologist Birgit Frauscher, MD. “With new options now available, regular re-evaluation of treatment is essential.” As a Level 4 Epilepsy Center, Duke is recognized by the National Association of Epilepsy Centers for providing the highest level of diagnostic, treatment, and surgical options.

Protect Your Brain Health with These 4 Powerful Nutrients

Lori Alton via NaturalHealth365 – Perhaps you’ve heard people joke about having “senior moments,” those temporary lapses of memory that can leave you searching for a word — or a lost set of car keys. Perhaps you’ve even had a few yourself. Is this a sign of poor brain health? Unless they occur so frequently that they interfere with daily life, these little lapses are probably just a sign of normal age-related memory loss – and of the inevitable fact that your brain is getting smaller every year. Loss of brain mass can threaten cognition, memory, mood – even life itself Brain shrinkage, or loss of volume in the brain, is a normal part of aging. However, abnormally pronounced brain shrinkage puts you at risk for cognitive and movement disorders – and even stroke or premature death. Research shows that people with smaller brain volumes have a 96 percent increase in their risk of stroke – as well as a 58 percent increase in risk of death from all causes. Cardiovascular disease can be a major contributor to brain shrinkage. In one study, patients with coronary artery disease were found to have significantly smaller amounts of gray matter – with worse performances on cognitive tests. Diabetes, sleep disorders, stress, and obesity can all accelerate brain shrinkage as well. Lifestyle factors, such as a toxic diet, a lack of physical activity, smoking, and excessive drinking, can also speed the process. Neuroscientists say brain shrinkage can be slowed significantly with lifestyle changes. In addition to following a healthy diet and getting active, you can protect your brain by supplementing with the following four nutrients. Combine three different B-complex vitamins for brain health B-complex vitamins help to regulate homocysteine, an amino acid associated with heart disease. High levels of homocysteine cause brain shrinkage and dementia – especially when the body is deficient in B vitamins. Doctors say it’s important for aging people to maintain optimal B vitamin levels, especially those with high homocysteine levels. Three of the B-complex vitamins – vitamin B-12, vitamin B-9, and vitamin B-6 – are especially helpful in retaining brain volume. Vitamin B-12, or cobalamin, is found in fish, meat, and dairy. It is needed by the body to metabolize fatty acids, an important component of brain cells. People with B-12 deficiencies experience shrinkage at a rate that is 5 times faster than that of people with higher levels. Vitamin B-9, known as folate, occurs naturally in leafy vegetables, legumes, fruits, and organ meats such as beef liver. In one study, people with higher folate levels experienced slower rates of brain atrophy – as well as a longer period of time progressing from mild cognitive impairment to full-blown dementia. Vitamin B-6, or pyridoxine, is important in the production of neurotransmitters and the absorption of vitamin B-12. It occurs naturally in meat, fish, dairy, lentils, and brown rice. In a controlled trial published in the scientific journal PLoS One, adults over 70 with mild cognitive impairment were given 800 mcg of folate, 500 mcg of vitamin B-12, and 20 mg of vitamin B-6 daily for two years and experienced brain shrinkage at a rate of 30 percent slower than the control group. For participants with elevated homocysteine at the beginning of the study, results were even more dramatic — they slowed their brain shrinkage rate by 53 percent. Are high-fat diets bad for the brain? Healthy fats – such as the omega-3 fatty acids in fish oils and nut oils – are a major part of brain cell membranes, and optimal levels can play a key role in protecting your brain. Higher levels of the omega-3 components known as DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) are associated with larger brain volumes. When DHA and EPA levels drop, age-related cognitive deficits worsen. Major depressive disorder and bipolar disorder are both associated with abnormal distributions in the brain of fatty acids. People with Alzheimer’s disease also show low levels of fatty acids. Omega-3s protect against over-excitation – a primary cause of age-related brain cell damage – while decreasing inflammation and protecting against damage from stress. Pomegranate juice sharpens memory and improves cognition Pomegranates are rich in anti-inflammatory, antioxidant, and neuroprotective plant-based compounds called polyphenols. This flavorful juice can help reduce overall fat content in obese people, help regulate blood sugar, and fight inflammation – “win/win” scenarios in the fight against brain shrinkage. And researchers have found that a mere 8 ounces of pomegranate juice a day can improve cognition and memory. Compound from grapes and berries may enlarge memory center Resveratrol is a phenol in red grapes, red wine, and darkly pigmented fruits such as blueberries. Studies showed that resveratrol increased volume in the hippocampus – the part of the brain associated with memory. It also helped protect against oxidative damage that leads to brain cell death and reduced injury to brain endothelial cells with high-fat diets. In a 2014 study published in the Journal of Neuroscience, adults who were overweight but otherwise healthy were given 200 mg of resveratrol daily for 26 weeks. Researchers found that resveratrol improved connections between the hippocampus and frontal sections of the brain and served to increase memory performance. They noted resveratrol’s potential as a novel strategy to maintain brain health during aging. As baby boomers round the corner into advanced age, avoiding loss of brain volume becomes a must for optimal health. Never underestimate the power of good (organic) nutrition and healthy lifestyle changes.

As Cannabis Users Age, Health Risks Appear to Grow

The AHA! Team — Wed, 13 Aug 2025 05:57:54 +0000

KFF Health News via News-Medical – “If you view cannabis as a medicine, you should be open to the idea that there are groups who probably shouldn’t use it and that there are potential adverse effects from it,” – “Because that is true of all medicines.” A cautionary tale Benjamin Han, a geriatrician and addiction medicine specialist at the University of California-San Diego, tells his students a cautionary tale about a 76-year-old patient who, like many older people, struggled with insomnia. “She had problems falling asleep, and she’d wake up in the middle of the night,” he said. “So her daughter brought her some sleep gummies” — edible cannabis candies. “She tried a gummy after dinner and waited half an hour,” Han said. Feeling no effects, she took another gummy, then one more — a total of four over several hours. Han advises patients who are trying cannabis to “start low; go slow,” beginning with products that contain just 1 or 2.5 milligrams of tetrahydrocannabinol, or THC, the psychoactive ingredient that many cannabis products contain. Each of the four gummies this patient took, however, contained 10 milligrams. The woman started experiencing intense anxiety and heart palpitations. A young person might have shrugged off such symptoms, but this patient had high blood pressure and atrial fibrillation, a heart arrhythmia. Frightened, she went to an emergency room. Lab tests and a cardiac work-up determined the woman wasn’t having a heart attack, and the staff sent her home. Her only lingering symptom was embarrassment, Han said. But what if she’d grown dizzy or lightheaded and was hurt in a fall? He said he has had patients injured in falls or while driving after using cannabis. What if the cannabis had interacted with the prescription drugs she took? “As a geriatrician, it gives me pause,” Han said. “Our brains are more sensitive to psychoactive substances as we age.” Thirty-nine states and the District of Columbia now allow cannabis use for medical reasons, and in 24 of those states, as well as the district, recreational use is also legal. As older adults’ use climbs, “the benefits are still unclear,” Han said. “But we’re seeing more evidence of potential harms.” A wave of recent research points to reasons for concern for older users, with cannabis-related emergency room visits and hospitalizations rising, and a Canadian study finding an association between such acute care and subsequent dementia. Older people are more apt than younger ones to try cannabis for therapeutic reasons: to relieve chronic pain, insomnia, or mental health issues, though evidence of its effectiveness in addressing those conditions remains thin, experts said. In an analysis of national survey data published June 2 in the medical journal JAMA, Han and his colleagues reported that “current” cannabis use (defined as use within the previous month) had jumped among adults age 65 or older to 7% of respondents in 2023, from 4.8% in 2021. In 2005, he pointed out, fewer than 1% of older adults reported using cannabis in the previous year. What’s driving the increase? Experts cite the steady march of state legalization — use by older people is highest in those states — while surveys show that the perceived risk of cannabis use has declined. One national survey found that a growing proportion of American adults — 44% in 2021 — erroneously thought it safer to smoke cannabis daily than cigarettes. The authors of the study, in JAMA Network Open, noted that “these views do not reflect the existing science on cannabis and tobacco smoke.” The cannabis industry also markets its products to older adults. The Trulieve chain gives a 10% discount, both in stores and online, to those it calls “wisdom” customers, 55 or older. Rise Dispensaries ran a yearlong cannabis education and empowerment program for two senior centers in Paterson, New Jersey, including field trips to its dispensary. The industry has many satisfied older customers. Liz Logan, 67, a freelance writer in Bronxville, New York, had grappled with sleep problems and anxiety for years, but the conditions grew particularly debilitating two years ago, as her husband was dying of Parkinson’s disease. “I’d frequently be awake until 5 or 6 in the morning,” she said. “It makes you crazy.” Looking online for edible cannabis products, Logan found that gummies containing cannabidiol, known as CBD, alone didn’t help, but those with 10 milligrams of THC did the trick without noticeable side effects. “I don’t worry about sleep anymore,” she said. “I’ve solved a lifelong problem.” But studies in the United States and Canada, which legalized nonmedical cannabis use for adults nationally in 2018, show climbing rates of cannabis-related health care use among older people, both in outpatient settings and in hospitals. California In California, for instance, cannabis-related emergency room visits by those 65 or older rose, to 395 per 100,000 visits in 2019 from about 21 in 2005. In Ontario, acute care (meaning emergency visits or hospital admissions) resulting from cannabis use increased fivefold in middle-aged adults from 2008 to 2021, and more than 26 times among those 65 and up. “It’s not reflective of everyone who’s using cannabis,” cautioned Daniel Myran, an investigator at the Bruyère Health Research Institute in Ottawa and lead author of the Ontario study. “It’s capturing people with more severe patterns.” But since other studies have shown increased cardiac risk among some cannabis users with heart disease or diabetes, “there’s a number of warning signals,” he said. Cannabis use disorder For example, a disturbing proportion of older veterans who currently use cannabis screen positive for cannabis use disorder, a recent JAMA Network Open study found. As with other substance use disorders, such patients “can tolerate high amounts,” said the lead author, Vira Pravosud, a cannabis researcher at the Northern California Institute for Research and Education. “They continue using even if it interferes with their social or work or family obligations” and may experience withdrawal if they stop. Among 4,500 older veterans (with an average age of 73) seeking care at Department of Veterans Affairs health facilities, researchers found that more than 10% had reported cannabis use within the previous 30 days. Of those, 36% fit the criteria for mild, moderate, or severe cannabis use disorder, as established in the Diagnostic and Statistical Manual of Mental Disorders. VA patients differ from the general population, Pravosud noted. They are much more likely to report substance misuse and have “higher rates of chronic diseases and disabilities, and mental health conditions like PTSD” that could lead to self-medication, she said. Current VA policies don’t require clinicians to ask patients about cannabis use. Pravosud thinks that they should. Moreover, “there’s increasing evidence of a potential effect on memory and cognition,” said Myran, citing his team’s study of Ontario patients with cannabis-related conditions going to emergency departments or being admitted to hospitals. Comparisons Compared with others of the same age and sex who were seeking care for other reasons, research shows these patients (ages 45 to 105) had 1.5 times the risk of a dementia diagnosis within five years, and 3.9 times the risk of that for the general population. Even after adjusting for chronic health conditions and sociodemographic factors, those seeking acute care resulting from cannabis use had a 23% higher dementia risk than patients with noncannabis-related ailments, and a 72% higher risk than the general population. None of these studies were randomized clinical trials, the researchers pointed out; they were observational and could not ascertain causality. Some cannabis research doesn’t specify whether users are smoking, vaping, ingesting or rubbing topical cannabis on aching joints; other studies lack relevant demographic information. Safer modes of consumption “It’s very frustrating that we’re not able to provide more individual guidance on safer modes of consumption, and on amounts of use that seem lower-risk,” Myran said. “It just highlights that the rapid expansion of regular cannabis use in North America is outpacing our knowledge.” Still, given the health vulnerabilities of older people, and the far greater potency of current cannabis products compared with the weed of their youth, he and other researchers urge caution. “If you view cannabis as a medicine, you should be open to the idea that there are groups who probably shouldn’t use it and that there are potential adverse effects from it,” he said. “Because that is true of all medicines.” Source: KFF Health News To read the original article click here.

Hair Dye WARNING: Undeniable Link Between Hair Dye Chemicals & Cancer

The AHA! Team — Wed, 13 Aug 2025 05:04:18 +0000

Dena Schmidt via NaturalHealth365 – Surprisingly, 75 percent of people in the U.S., Japan, and Europe dye their hair regularly. Gray hair can make people look prematurely old, and hair color is used to preserve that more youthful appearance. Sometimes, people just want a change from their natural hair color, and dyeing it can help them make a ‘fashion statement.’ In truth, hair coloring is an ancient practice. However, in the past, people used natural substances such as henna and other pigments found in plants, soil, and clay. Today, most of the store-bought hair color options are made with harsh, toxic chemicals that can pose a serious health risk when used regularly over time. The dangers of hair color aren’t highly publicized Some of the risks and side effects of the chemicals found in hair dyes include cancers of the kidney, bladder, and breast, as well as blood-based cancers like leukemia and lymphoma. But don’t expect your local salon to post any warning signs soon – for obvious reasons. The “official word” on hair color products that contain harsh chemicals is far from cautionary. However, one of the common chemicals used, called P-phenylenediamine (PPD), is documented as causing side effects like asthma, gastritis, severe dermatitis, eye irritation, vertigo, tremors, convulsions, kidney failure, and coma in those who are exposed to it. Now, a new study adds to growing concerns by revealing that another synthetic hair dye pigment, 4-Chloro-orthophenylenediamine (4-Cl-OPD), can cause significant DNA damage when exposed to high nitric oxide levels. Researchers found that this damage leads to structural changes in DNA, triggering immune system reactions in those with prolonged hair dye use. The study even linked these immune responses to hepatocellular carcinoma, suggesting that chronic hair dye exposure could contribute to a pro-inflammatory, cancer-promoting environment. Some hair color products contain thousands of chemical compounds However, PPD and 4-Cl-OPD aren’t the only risks. Some hair color products contain as many as 5,000 chemicals, including lead acetate and ammonia. The chemicals in hair color products also interact with the substances in human hair to produce harmful effects. Hair colors come in temporary, semi-permanent, and permanent solutions. However, 80 percent of the market comprises permanent colors containing agents like couplers and intermediates that react with hydrogen peroxide. While the worst hair color product ingredients were banned in the 1970s, many products still contain dangerous substances. Research confirms the health hazards of hair color products Numerous studies have substantiated these hair color risks. A 1994 National Cancer Institute report covered the dangers of dark hair dyes used over extended periods. They were found to raise the risk of cancers like multiple myeloma and non-Hodgkin’s lymphoma. Another study by the International Agency for Research on Cancer (IARC) found that hairdressers who worked regularly with these products had an increased risk of bladder cancer, leukemia, and lymphoma. The scalp has a rich blood supply, making it easy for the toxic chemicals in hair dyes to soak into the skin. During the 30 minutes, hair dyes remain in contact with the scalp and can easily enter the blood supply. Fortunately, there is a better way. Avoid the cancer risk: Consider safer, non-toxic alternatives Fortunately, there are safer alternatives to these toxic products. Hairprint is a natural hair color brand developed by award-winning chemist John Warner. Instead of harsh chemicals, it contains non-toxic, plant-based, food-grade pigments and minerals. Best of all, Hairprint has a restorative effect on hair, enriching it and restoring the shine and luster that can be lost as hair ages. Hairprint products are also hypoallergenic and free of odor.

Surprising Secret to Sharper Memory & Mental Clarity

The AHA! Team — Fri, 08 Aug 2025 05:20:18 +0000

Lori Alton via NaturalHealth365 – A familiar staple of spice racks and kitchen cabinets, rosemary is prized by cooks for the piquant flavor it lends to recipes. However, recent research shows that this common culinary herb provides some uncommon benefits when it comes to cognitive function and recall. A British study found that sniffing the essential oil of this ancient herb can improve memory by a remarkable 75 percent, making it a possible treatment for memory problems. Further supporting this, a 2024 study published in Adv Gerontol found that inhaling rosemary essential oil helped elderly participants improve performance in mental tasks, particularly word recognition and proofreading, highlighting its potential for enhancing cognitive function. How did researchers arrive at these results about rosemary? The British study, conducted by psychologists at Northumbria University in Newcastle, involved 66 people. Some were exposed to a rosemary-scented room, in which four drops of essential oil were placed on an aroma stream diffuser and switched on for five minutes before the participants entered. Another group worked in an unscented room. The psychologists found that the participants in the rosemary-scented room performed between 60 and 75 percent better on assorted memory tasks and simple arithmetic than the control group – an impressive result. As part of the study, researchers took blood samples to detect levels of 1,8-cineole, a constituent of rosemary linked to improving memory function. Participants in the rosemary room had higher levels of cineole, demonstrating that the compound can enter the bloodstream through inhalation. In their findings, the team concluded that rosemary could have implications for treating memory impairments, especially in older adults experiencing some decline. Rosemary seems particularly helpful in promoting “prospective memory,” helping people remember future events such as appointments or medication schedules. New studies build on earlier research In an earlier study published in 2003 in the International Journal of Neuroscience, researchers examined the effects of rosemary and lavender and found that rosemary produced significant enhancements in performance for overall memory quality. Interestingly, lavender oil deterred memory, probably because of its mildly sedating effects. While lavender helped people feel more “content,” compared to the placebo, rosemary helped people feel simultaneously more content and alert. In a study of aromatherapy published in Psychogeriatrics, researchers examined the effects of rosemary and lemon administered in the morning – and lavender and orange in the evening – on patients with dementia. The team found that patients experienced significant improvement in personal orientation – with no side effects. Other studies have supported the ability of rosemary to both promote concentration and enhance memory of past events. Research corroborates ancient wisdom Scientifically known as Rosmarinus officinalis, natural healers have long used rosemary to boost the immune system, reduce inflammation, fight pathogens, and promote healthy digestion. Although modern research is exciting, rosemary’s ability to improve memory and facilitate learning has been known since antiquity. The ancient Greeks treasured the herb for its memory-enhancing properties, and it was customary for scholars to wear strands of rosemary in their hair when taking exams. The herb’s useful effects were no secret in Elizabethan England, either. Shakespeare alludes in several plays to “rosemary for remembrance.” Fight cancer and oxidative stress in your brain The antioxidant value, or ORAC score, of rosemary, is a massive 3,300, giving it the same potent free radical-fighting power as goji berries. This herb is rich in carnosic acid, an antioxidant that fights oxidative stress in the brain. Another constituent, carnosol, is strongly antioxidant and anti-inflammatory as well. Researchers have found that carnosol selectively targets cancer cells while leaving healthy cells unharmed. Of course, studies into the cancer-fighting effects are ongoing. Regarding usage, some natural health experts recommend adding a few drops of essential rosemary oil to a diffuser and running it for about an hour daily. For topical use, dilute a small amount of the essential oil in a carrier oil and massage it onto your upper neck for potential cognitive benefits. We suggest you check with a trusted holistic healthcare provider before using any herb to enhance memory. This is especially important if you have any brain health issues.

Nomophobia: How Fear of Being Without Your Phone Harms Health (& What to Do About It)

The AHA! Team — Fri, 08 Aug 2025 05:10:19 +0000

Kissairis Munoz via Dr. Axe – In today’s hyper-connected world, many people experience anxiety when they are without their smartphones. This condition, known as nomophobia, has become increasingly common. What exactly is nomophobia, and how can you recognize and address it? Does the “ding” of your phone have you dropping whatever you’re doing to see who “liked” your latest Facebook status? Are you answering work emails before rubbing the sleep from your eyes? Does a low battery icon leave you quivering in fear? You, my friend, are likely suffering from nomophobia. Thankfully, there are ways to treat this condition to help address your smartphone addiction. What Is Nomophobia? Nomophobia, short for “no-mobile-phone phobia,” is the fear of being without a mobile phone or being unable to use it. The term originated from a 2008 study commissioned by the U.K. Post Office to examine the anxieties mobile phone users experience. The study found that nearly 53 percent of mobile phone users in the U.K. tend to feel anxious when they “lose their mobile phone, run out of battery or credit, or have no network coverage.” More simply put, nomophobia is having a smartphone addiction, and it’s a “first world problem” that’s showing no signs of slowing down, regardless of age. While it might sound silly — can you really be addicted to a handheld device? — the implications are real. About half of U.S. adults are checking their phones at least several times an hour, with 11 percent tapping their screens awake every few minutes. No space is safe from the rush of a new tweet, either. Almost one in 10 Americans has admitted to using her phone during sex, and among young adults ages 18 to 34, the number is even higher: One in five has engaged with his smartphone when being intimate. Is it a surprise, then, that 12 percent think that smartphones are detrimental to relationships? When you combine nomophobia with cars, things get even scarier. Among American adult drivers, more than 27 percent have sent or read texts while driving. Among young adults, that number shoots up to 34 percent. What’s the harm in interacting with your phone at a red light or when traffic is heavy? Consider the fact that text messaging while driving makes a crash 23 times more likely. Yikes. Symptoms While there is no set criteria to diagnose this condition, experts believe nomophobia is a smartphone addiction and/or dependence. Recognizing the signs of nomophobia is the first step toward addressing it. Common symptoms include: Panic or anxiety when separated from your phone Checking your phone repeatedly without receiving notifications Doomscrolling Avoiding places or situations where phone use is restricted Feeling uneasy when your phone is out of sight Excessive time spent on your phone, impacting daily life Respiratory alterations Trembling Perspiration Agitation Disorientation Tachycardia Inability to turn off your smartphone Taking the phone everywhere Fear of being without phone access (no internet connection or cell signal) Fear of not being able to use phone in case of emergency Stressing about neglecting your online persona Socially isolating and skipping activities to spend more time on your smartphone Increased heart rate According to research, some signs that someone may have nomophobia can include the fear of: Feeling disconnected Not have immediate access to information Giving up the convenience of your mobile device Not being able to contact and communicate with others Causes Several factors contribute to the development of nomophobia: Social connectivity: Fear of missing out (FOMO) on social interactions and updates. Dependence on technology: Increasing reliance on smartphones for various daily tasks. Instant gratification: The immediate access to information and entertainment that phones provide. Psychological factors: Underlying anxiety disorders or personality traits. Other possible causes that research has unearthed include: obsessive thoughts and compulsive smartphone behaviors extremely large number of hours using a smartphone each day social discomfort and feelings of inferiority Damage Nomophobia Does Even for those of us who don’t text and drive, nomophobia has serious consequences. It can have several adverse effects on an individual’s well-being, such as: Mental health: Increased anxiety, depression, stress and feelings of loneliness. Physical health: Poor posture, eye strain and sleep disturbances due to excessive phone use. Social interactions: Reduced face-to-face communication and weakened relationships. Productivity: Decreased focus and productivity at work or school due to constant phone checking. Furthermore, research on nomophobia in adolescents and young adults published in 2021 in Frontier in Psychiatry concluded that “excessive smartphone use is associated with psychiatric, cognitive, emotional, medical and brain changes that should be considered by health and education professionals.” The authors revealed that “excessive smartphone use is associated with difficulties in cognitive-emotion regulation, impulsivity, impaired cognitive function, addiction to social networking, shyness and low self-esteem. Medical problems include sleep problems, reduced physical fitness, unhealthy eating habits, pain and migraines, reduced cognitive control and changes in the brain’s gray matter volume.” Here’s more on the negative effects of smartphone addiction: 1. You’re wasting time While many of us are convinced that multitasking allows us to get more done, multitasking doesn’t really work. Not only are our brains unequipped to handle two dissimilar tasks at once, but trying to accomplish several things at once ends up wasting more time than saving any. Think about it: How well do you retain information when someone’s talking to you as you’re scrolling through emails or watching the latest cat video your friend posted? Even if your body is in a room, it’s easy to miss important information when your brain is somewhere else completely. Plus, let’s face it: No one likes talking to someone who’s “listening” with her face buried in a screen. 2. You’re more anxious Not having your phone around can increase anxiety. One British study found that 51 percent of participants suffer “extreme tech anxiety” when separated from their smartphones. Some of that stems from feeling that, if we’re apart from our phones, we won’t be included when friends make plans or won’t know what the latest Facebook meme is. Even our bodies are starting to recognize when our phones aren’t around. A University of Missouri study discovered that iPhone users who parted with their devices during situations that require a significant amount of attention, like taking a test or completing a work assignment, could result in poorer performance. That’s because, when participants were separated from their phones and then asked to complete simple word search puzzles, their heart rates and blood pressure increased — as did their feelings of anxiety and unpleasantness. 3. You’re not sleeping as well “Check email one last time, make sure no friends posted anything interesting, one last glance of Instagram … oh wait, a new work email came in. Darn it, that afternoon meeting got pushed up. Did I prep enough for it? Should I review things one more time? Wait, it’s late already. I guess I’ll just think about it for the next half-hour while I toss and turn trying to fall asleep.” Sound familiar? Being inundated with stimulating information right before bed often means you can’t sleep well, particularly when we’re presented with situations beyond our control. And most of us are sleeping with our phones. In almost every age group, at least 40 percent of Americans sleep with their phones within reach. For those 25 to 29 years old, the number’s even higher: Almost 80 percent are snuggling up to their devices. The danger isn’t only that each beep overnight has the potential to wake us up. Smartphones also emit a blue light, signaling to the brain that it’s time to wake up. Blue lights suppress melatonin, the hormone that dictates our sleep rhythms. Yes, the struggle to sleep with your phone is real. 4. Your children are picking up your naughty habits “Do as I say, not as I do” is all too real when it comes to smartphone time. Even as parents ask children and teens to lay off Snapchat or put their phones down during dinner, they’re checking calendars, answering texts or indulging in one last game of Candy Crush. It stands to reason then that in almost every study of smartphone use, young adults have the highest usage rates. Children are learning that always being connected is normal — and missing out on the importance of human-to-human interaction. Are You Addicted to Your Smartphone? If any of these apply to you, all signs point to a smartphone addiction: You reach for your smartphone upon waking up and right before bed. It’s not uncommon for you to catch up on emails or the latest in the news while you’re eating. When your phone is out of reach, low on battery or (gasp) completely turned off, you feel anxious or stressed out. Being out of cell phone signal makes you feel like you might be missing something. You live for that next Instagrammable moment. Pavlov’s dogs have nothing on you: When you hear that familiar text sound, you perk up. You’ve checked your phone at least once while reading this article! Treatment Addressing nomophobia involves a combination of strategies: Digital detox: Gradually reducing the amount of time spent on your phone. Setting boundaries: Establishing phone-free zones or times, such as during meals or before bed. Mindfulness practices: Engaging in activities that promote relaxation and reduce anxiety, such as meditation or yoga. Professional help: Seeking therapy or counseling to address underlying anxiety or dependence issues. Behavioral therapies such as cognitive behavior therapy, exposure therapy, systematic desensitization, aversion therapy and hypnotherapy are often used to help treat phobias. Medications: Certain medications can help in severe cases. Support groups: Realizing you aren’t alone and talking with others can help. Self-care: Do things to improve your mental and physical well-being, such as progressive muscle relaxation, breathing exercises, calming activities, ecotherapy and getting outdoors, etc. In addition, follow these steps to enjoy a life that’s complemented, not ruled, by your smartphone: 1. Turn off your cell phone at least an hour before bed Give your brain a chance to unwind and commit to turning off your phone an hour before bedtime. That means off, not just on silent. Those vibrations and blinking lights are still harmful, as is knowing that you’re just one reach away from seeing the latest. Remember, nomophobia never sleeps, and neither will you. No wonder so many of us are always tired, huh? If you have a legitimate reason for keeping your phone on — your daughter is out with friends or your parents are elderly and you don’t have a landline — turn your phone on “do not disturb,” and place your phone on the other side of the room. In this mode, your phone will silence all notifications but allow you to enable exceptions, such as a phone call from a specific number. Remember: Seeing how many “likes” your last Instagram post received is not a legitimate reason. “But I use my phone as my alarm clock,” you say. “I need it nearby!” To that I respond … 2. Stop shacking up with your phone Get a real alarm clock. (Yes, you can still find these Stone Age relics.) Not only will this allow you to turn off your phone completely overnight (again, unless you need to stay on alert for a family member and don’t have a landline), but instead of waking up with the temptation to see what you missed overnight, you can spend the first moments of the morning stretching, thinking about what’s on schedule for the day or basically doing anything other than checking your phone. For extra credit, I challenge you not to turn your phone on again until your morning routine is finished: You’ve exercised, showered, dressed, eaten breakfast, maybe even read the paper (remember that pastime!) and pushed the kids out the door. 3. Set certain times to check your phone Do you really need to look at every single email the second it’s received? Save your sanity and simultaneously help your productivity by designating certain times to glance at...
