Why We Shouldn’t (and Can’t ) Just “Forgive & Forget”

Dr. Caroline Leaf – In this podcast (episode #272) and blog, I talk about why forgetting doesn’t fix or heal something. As much we would love to permanently forget the bad things that happen to us, we can’t just erase traumatic events from our memory, as they impact our brain and body. As I have said many times before, thoughts are real physical structures we build into our brain with our mind in response to what we experience. Here’s how this works: how we react or respond to various life situations and the world around us is called the mind-in-action. The mind-in-action is how you uniquely think, feel, and choose. This mind-in-action changes the way your brain is shaped (through neuroplasticity) and how it functions, as well as your biochemistry, and the genes associated with mental and physical health, which is why mind-management is essential! Let’s look at a traumatic experience we are all too familiar with. Our personal experience of COVID-19 is quite literally a physical tree-like structure in our brains with all the associated memories of our unique experiences, which can affect us mentally, emotionally and physically. No matter how much we pretend that this pandemic doesn’t exist, or want to shut our eyes and hope it goes away, we cannot, as it does exist, and our unique experience of it affects us all in different ways, and we all need to find different ways to manage these effects. That is not to say all types of forgetting are bad. We may distract ourselves temporarily to cope in the moment or compartmentalize our experiences to deal with another pressing matter, which is fine and a very human thing to do! However, we cannot escape the long-term mental and physical repercussions of a traumatic experience because it is as real as a virus like COVID-19, eliciting the same immune responses in the brain and body. We cannot just “forget”; we have to learn how to reconceptualize our pain and fears through mind-management, as I discuss in my latest book Cleaning Up Your Mental Mess. In fact, there are some great ways to distract your mind in a healthy way, like the box and windows technique, where you make a mental note to start dealing with the root of the trauma or pain when you are ready. But, at the end of the day, you need to learn to become a healthy responder instead of just reacting to what happens to you, or trying to forget or avoid it. You, with your mind that is always in action, are powerful; you are the ultimate change agent in your life. What does this look like? When you learn how to manage your mind and self-regulate your thinking, this builds healthy neural networks in your brain, which lay the foundation for more cognitive resilience and healthier responses to stressful events. The more you practice this way of thinking, the more you can learn to be a “first responder” in every and all situations. Essentially, you are learning how to catch and edit your thoughts and reactions before they trigger toxic chain reactions and become ingrained neural networks, a.k.a. bad habits. Mind management also teaches us how to embrace, process, and reconceptualize thoughts that have already become enmeshed in the networks of our minds as trauma reactions and negative thinking patterns. This is a lifelong journey, a lifestyle, but one that’s well worth the effort! Indeed, if we don’t transform our pain through reconceptualization, we can transmit it, and it can take over our thinking and relationships. We can get ourselves into serious cycles of toxic rumination and worry if we refuse to face our issues head-on. As I always say, it is in the breakdown that we break down toxic thoughts, habits, and trauma. We all need to learn how to reflect on our experiences in a way that helps us accept that even though we may not be able to make sense of them, we can still deal with them and move forward!

Can Sleep Protect Us from Forgetting Old Memories?

University of California – San Diego via EurekAlert – From lowering your risk of obesity and cardiovascular disease to improving your concentration and overall daily performance, sleep has been proven to play a critical role in our health. In a new study, researchers at University of California San Diego School of Medicine report that sleep may also help people to learn continuously through their lifetime. Writing in the August 4, 2020 online issue of eLife, researchers used computational models capable of simulating different brain states, such as sleep and awake, to examine how sleep consolidates newly encoded memories and prevents damage to old memories. “The brain is very busy when we sleep, repeating what we have learned during the day. Sleep helps reorganize memories and presents them in the most efficient way. Our findings suggest that memories are dynamic, not static. In other words, memories, even old memories, are not final. Sleep constantly updates them,” said Maksim Bazhenov, PhD, lead author of the study and professor of medicine at UC San Diego. “We predict that during the sleep cycle, both old and new memories are spontaneously replayed, which prevents forgetting and increases recall performance.” Bazhenov said that memory replay during sleep plays a protective role against forgetting by allowing the same populations of neurons to store multiple interfering memories. “We learn many new things on a daily basis and those memories compete with old memories. To accommodate all memories, we need sleep.” For example, imagine learning how to navigate to a parking lot by going left at one stop sign and right at one traffic light. The next day, you have to learn how to get to a different parking lot using different directions. Bazhenov said sleep consolidates those memories to allow recollection of both. “When you play tennis, you have a certain muscle memory. If you then learn how to play golf, you have to learn how to move the same muscles in a different way. Sleep makes sure that learning golf does not erase how to play tennis and makes it possible for different memories to coexist in the brain,” said Bazhenov. The authors suggest that the restorative value of sleep may be what is lacking in current state-of-the-art computer systems that power self-driving cars and recognize images with performances that far exceed humans. However, these artificial intelligence systems lack the ability to learn continuously and will forget old knowledge when new information is learned. “We may need to add a sleep-like state to computer and robotic systems to prevent forgetting after new learning and to make them able to learn continuously,” said Bazhenov. Bazhenov said the study results could lead to developing new stimulation techniques during sleep to improve memory and learning. This may be particularly important in older adults or persons suffering from learning disabilities. “While sleep is certainly involved in many important brain and body functions, it may be critical for making possible what we call human intelligence — the ability to learn continuously from experience, to create new knowledge and to adapt as the world changes around us,” said Bazhenov.
