Chronic stress and memory loss

When it comes to memory loss we often think of diseases like Alzheimer’s or traumatic brain injuries. As college students, we don’t think of the reasons as to why we forget our books in our cars or why that assignment slipped out minds. We simply put it to being absent minded or the fact that we have other things going on that distract us. ¬†Stress isn’t the first thing that comes to mind when as a reason we forget things. However a recent study done in 2010 suggests that it may be the cause.

The study, A critical review of chronic stress effects on spatial learning and memory by Cheryl Conrad suggests that chronic stress vs. acute or high-levels of stress actually reduce spatial memory.  We have been learning recently about spatial memory, which is in charge of being familiar with our environment. We need our spatial memory to find our way around campus, We also need it for our spatial working memory to temporarily keep information while we take a test or work on an assignment. These qualities are extremely important in the daily lives of college students.

Researchers at the University of Iowa found the connection between the hormone found in stress-cortisol and short-term memory with rats. The amount of cortisol reduced the number of synaptic connections made in the pre-frontal cortex reducing the success of short-term memory.

There is a difference between long-term memory and stress. If the stress is acute or high such as experiencing an earthquake or getting into a car accident, your memory is actually improved and the ability to recall these events are easier because they are stored in the area responsible for survival. Low levels of chronic stress or anxiety can alter the brain and cause damage to memory. White matter in the brain is increases with stress, this is good for sending signals such as messages across the brain but reduces neurons that are in charge of information processing. This is shown in research on PTSD patients with increased white matter and long-term stress.

Researchers at Berkley suggest that the effects of long-term stress and anxiety in the younger generation may be the cause for mood disorders, learning disabilities and anxiety. From this I think we can all take the suggestions to reduce stress in our lives and manage a healthy balance. Anything from saying no to an extra meeting here and there or going for a walk on a nice day to get out of the office. We all need to practice self-care so we can take care of our memories in the long run.
