It's not uncommon to feel disorganized and forgetful when you're under a lot of stress. But over the long term, stress may actually change your brain in ways that affect your memory.
Studies in both animals and people show pretty clearly that stress can affect how the brain functions, says Dr. Kerry Ressler, chief scientific officer McLean Hospital and professor of psychiatry Harvard Medical School. Scientists have seen changes in how the brain processes information when people experience either real-life stress or stress manufactured in a research setting. (For the latter, researchers might challenge subjects to perform a difficult task, such as counting backward from the number 1,073 by 13s while being graded.) Either type of stress seems to interfere with cognition, attention, and memory, he says.
Stress affects not only memory and many other brain functions, like mood and anxiety, but also promotes inflammation, which adversely affects heart health, says Jill Goldstein, a professor of psychiatry and medicine Harvard Medical School. Thus, stress has been associated with multiple chronic diseases of the brain and heart. In addition, it can affect men and women differently, she says.
Stress and the brain
To understand why stress affects thinking and memory, it's important to understand a little about how the brain works. Your brain isn't just a single unit, but a group of different parts that perform different tasks, says Dr. Ressler. Researchers believe that when one part of your brain is engaged, the other parts of your brain may not have as much energy to handle their own vital tasks, he says. For example, if you are in a dangerous or emotionally taxing situation, the amygdala (the part of your brain that governs your survival instincts) may take over, leaving the parts of your brain that help to store memories and perform higher-order tasks with less energy and ability to get their own jobs done. "The basic idea is that the brain is shunting its resources because it's in survival mode, not memory mode," says Dr. Ressler. This is why you might be more forgetful when you are under stress or may even experience memory lapses during traumatic events.
The effect that stress has on the brain and body toàn thân may also differ depending on when it occurs in the course of someone's life, says Goldstein. Certain hormones, known as gonadal hormones — which are secreted in large amounts during fetal development, puberty, and pregnancy and depleted during menopause — may play a role in how stress affects an individual, says Goldstein. "For example, reductions in the gonadal hormone estradiol during the menopausal transition may change how our brain responds to stress," she says.
Protect yourself from damaging stress
To better cope with stress, consider how you might minimize factors that make it worse. Here are some tips that can help you better manage stress and hopefully prevent some of the damaging effects it could have on your brain.
Establish some control over your situation. If stress isn't predictable, focus on controlling the things that are. "Having a routine is good for development and health," says Dr. Kerry Ressler, professor of psychiatry Harvard Medical School. Predictability combats stress.
Get a good night's sleep. Stress can result in sleep difficulties, and the resulting lack of sleep can make stress worse. "Sleep deprivation makes parts of the brain that handle higher-order functions work less well," says Dr. Ressler. Having healthy sleep habits can help. This includes going to bed and waking up the same time each day, avoiding caffeine after noon, and creating a relaxing sleep environment.
Get organized. Using strategies to help manage your workload can also reduce stress. For example, each day, create a concrete list of tasks you need to accomplish. This way, your duties won't seem overwhelming. Making a list also gives you a clear end point so you know when you are done. "Laying tasks out like this helps reduce the feeling that the brain is being bombarded," he says. It can also help you predict when you are likely to be stressed.
Get help if you need it. Reaching out can help you become more resilient and better able to manage stress, which may ultimately protect your brain health. Earlier intervention may reduce disability caused by stress-related complications later on.
Change your attitude toward stress. "A life without stress is not only impossible, but also would likely be pretty uninteresting — in fact, a certain degree of stress is helpful for growth," says Dr. Ressler. So, rather than striving for no stress, strive for healthier responses to stress.
Long-term brain changes
There is evidence that chronic (persistent) stress may actually rewire your brain, says Dr. Ressler. Scientists have learned that animals that experience prolonged stress have less activity in the parts of their brain that handle higher-order tasks — for example, the prefrontal cortex — and more activity in the primitive parts of their brain that are focused on survival, such as the amygdala. It's much like what would happen if you exercised one part of your body toàn thân and not another. The part that was activated more often would become stronger, and the part that got less attention would get weaker, he says. This is what appears to happen in the brain when it is under continuous stress: it essentially builds up the part of the brain designed to handle threats, and the part of the brain tasked with more complex thought takes a back seat.
These brain changes may be reversible in some instances, says Dr. Ressler, but may be more difficult to reverse in others, depending on the type and the duration of the stress. While stressful childhood experiences seem to take more of a toll on the developing brain, some research has found that people who demonstrate resilience in the face of past childhood trauma actually appear to have generated new brain mechanisms to compensate. It's thought that these new pathways help to overcome stress-related brain changes that formed earlier in life, he says.
Is all stress created equal?
While the effect of stress on the brain is well documented, it's less clear exactly what type of stress will prove damaging and raise the risk of memory problems later in life. Do brain problems occur when you are under a small amount of stress or only when you experience long-term stress?
"That's a tough question, because stress is a broad term that is used to describe a lot of different things," says Dr. Ressler. The stress you might experience before you take a test is likely very different from the stress of being involved in a car accident or from a prolonged illness. "Certainly, more stress is likely worse, and long-term stress is generally worse than short-term stress," says Dr. Ressler.
But there are additional factors that make stress more harmful, he says. In particular:
The stress is unpredictable. Animal research shows that animals that could anticipate a stressor — for example, they received a shock after a light turned on — were less stressed than animals that received the same number of shocks randomly. The same is true in humans, says Dr. Ressler. If a person can anticipate stress, it is less damaging than stress that appears to be more random.
There is no time limit on the stress. If you are stressed about a presentation work or an upcoming exam, the stress you are experiencing has an end point when you know you will get relief. If the stress has no end point — for example, you are chronically stressed about finances — it may be more challenging to cope with.
You lack support. If you feel supported during your stress, you are likely to weather it more successfully than if you don't.
What type of stress causes memory loss?
During a chronic stress response, areas of the brain can be overstimulated, which can cause a person to forget what happened. It explains why we may have difficulty recalling events when experiencing chronic stress. We may also have trouble focusing and remembering things over time.What effect does stress have on memory?
Stress and Memory Stress can affect how memories are formed. When stressed, people have a more difficult time creating short-term memories and turning those short-term memories into long-term memories, meaning that it is more difficult to learn when stressed. Stress can affect the type of memories we form as well.What causes deterioration of memory?
Concussion or head trauma. Not enough oxygen getting to the brain when your heart or breathing is stopped for too long. Severe brain infection or infection around brain. Major surgery or severe illness, including brain surgery.Does stress affect memory loss?
Many common conditions and even some substances can cause forgetfulness. Lyndsay shared some: Depression, anxiety and stress – “These are common causes of forgetfulness,” Lyndsay said. “Stress and mood disturbances can act as a distraction and make it difficult to focus, which can lead to memory problems.”
