Acute Stress And Memory Impairment
Experiencing an acute highly stressful situation can interfere with subsequent information processing. This holds true particularly for those circumstances in which a stressed individual is required to retrieve previously stored information while the acquisition of new information is shown to be particularly resistant to disruption in experimental animals. In fact, most rodent studies in which acute stress has been applied before animals were confronted to learn a hippocampus-dependent task failed to find alterations in the acquisition rate., If any consistent effects were observed, in most cases they were not evident in the performance of animals during the training phase, but appeared in subsequent retention tests.
For example, Baker and Kim showed that exposure to uncontrollable stress can affect a nonspatial task, the object-recognition memory. In their study, rats given inescapable restraint and tail-shock stress just before exposure to a novel object recognition task showed normal memory when tested 5 min after first exposure to objects, but were impaired when tested 3 hours later. Control rats displayed a preference for a novel object when they were tested at different time delays . Unlike the unstressed controls, at the 3-hour posttraining test, stressed animals spent comparable time exploring novel and familiar objects.
How Does Stress Affect Your Memory: The Inside Story
When under stress, brain freeze like what Jonas encountered happens mostly because your thinking is preoccupied with the stress-inducing stimuli am I looking cool on TV blocking out other thoughts.
But thats not the complete picture.
While low levels of anxiety can affect your ability to recall information high-stress situations, like being robbed at gunpoint, increases your brains ability to encode and recall traumatic events.
A study by Marloes J. A. G. Henckens and team demonstrated how acute stress is accompanied by a shift into a hypervigilant mode of sensory processing in combination with increased allocation of neural resources to noise reduction. This reduction of task-irrelevant ambient noise, in combination with a stress-hormone-induced optimal state for neural plasticity, may explain why stressful events attain a privileged position in memory.
Anxiety And Memory Loss
Memory loss can be a confusing and frightening anxiety symptom. It’s also an extremely common symptom, but the memories that people lose are often so minute that people don’t realize they’re losing them.
Memory loss is a byproduct of stress, but various other anxiety symptoms can actually create further memory loss as well. Below, we’ll explore the effects of memory loss on anxiety and provide tips for controlling it.

Why Use A Memory Palace
It boils down to this:
The Memory Palace is the best memory technique because as a foundational learning technique, it allows you to develop and use spatial memory in a way that unlocks the power of autobiographical memory, episodic memory, semantic memory and more.
This enables you to move information into long-term memory faster and with reliable permanence.
Building a Memory Palace is a simple technique. You start by associating information with specific areas of a familiar location.
Then you walk through that location and place pieces of information that you wish to memorize in specific areas. When you want to recall that information, you go through that mental path and access that information easily.
If you are interested in this memory method, click on the image below:
You can use more than just visual imagery to remember information through association!
Truly magnetic imagery involves a combination of these six Magnetic Modes:
A quick memory tip:
If you are struggling to remember these Magnetic Modes, rearrange them to make the acronym COG KAV. Next, create the image of a giant machine in a cave. Simple? Now, you will never forget your Magnetic Modes. Heres an infographic to help make this strategy clearer:

Chronic Stress Leads To Brain Inflammation And Memory Loss
People who experience chronic stress due to bullying or a tough job also run a higher risk of memory loss, according to a new study published in The Journal of Neuroscience.
Researchers led by Jonathan Godbout, associate professor of neuroscience at Ohio State University, investigated the relationship between prolonged stress and short-term memory loss in mice.
Ultimately, the researchers hope the findings will help people who live with ongoing stress.
The team had mice get used to a maze with an escape hole. They then exposed the mice to repeat visits from a larger, aggressive intruder mouse.
Mice that repeatedly had to confront the intruder found it harder to remember the location of the escape hole, whereas the mice that were not stressed were able to find it.
Symptoms Of Mild Cognitive Impairment
Mild cognitive impairment is an intermediate stage between normal age-related cognitive changes and the more serious symptoms that indicate dementia.
MCI can involve problems with memory, language, thinking, and judgment that are greater than normal age-related changes, but the line between MCI and normal memory problems is not always a clear one. The difference is often one of degrees. For example, its normal as you age to have some problems remembering the names of people. However, its not normal to forget the names of your close family and friends and then still be unable to recall them after a period of time.
If you have mild cognitive impairment, you and your family or close friends will likely be aware of the decline in your memory or mental function. But, unlike people with full-blown dementia, you are still able to function in your daily life without relying on others.
While many people with MCI eventually develop Alzheimers disease or another type of dementia, that doesnt mean its inevitable. Some people with MCI plateau at a relatively mild stage of decline while others even return to normal. The course is difficult to predict, but in general, the greater the degree of memory impairment, the greater your risk of developing dementia some time in the future.

The Relationship Between Anxiety And Memory Loss
Anxiety is a normal reaction to stress opens in new window with specific benefits, according to the American Psychiatric Association. Anxiety not only alerts you of dangers, but it helps you prepare for and pay attention to them.
Excessive amounts of fear or anxiety, however, can lead to anxiety disorders. Anxiety disorders make up the most common type of mental disorders, affecting nearly 30 percent of adults at some point in their lives.
One part of the body affected by anxiety and stress is the nervous system, which plays a primary role in basic functions like memory and learning. As a result, persistent anxiety and memory loss are associated.
Common Causes Of Forgetfulness
Memory slips are aggravating, frustrating, and sometimes worrisome. When they happen more than they should, they can trigger fears of looming dementia or Alzheimers disease. But there are some treatable causes of forgetfulness. Here are six common ones.
Lack of sleep. Not getting enough sleep is perhaps the greatest unappreciated cause of forgetfulness. Too little restful sleep can also lead to mood changes and anxiety, which in turn contribute to problems with memory.
Medications. Tranquilizers, antidepressants, some blood pressure drugs, and other medications can affect memory, usually by causing sedation or confusion. That can make it difficult to pay close attention to new things. Talk to your doctor or pharmacist if you suspect that a new medication is taking the edge off your memory. As shown in the table below, alternatives are usually available.
Medications that may affect memory and possible substitutes
If you take these drugs
ask about switching to one of these drugs
another antidepressant such as fluoxetine or sertraline , or a different type of antidepressant such as duloxetine or venlafaxine
Underactive thyroid. A faltering thyroid can affect memory . A simple blood test can tell if your thyroid is doing its job properly.

Physical Trauma And Memory Loss
Physical trauma can greatly affect your memory, especially if brain damage occurs as a result of the injury. Physical trauma such as a head injury or stroke can damage the brain and impair a persons ability to process information and store information, the main functions of memory.
Another form of brain damage that directly affects memory is Wernicke-Korsakoff Syndrome, which is a consequence of chronic alcohol abuse. Wernicke-Korsakoff Syndrome is a combination of two disorders: Wernickes Disorder, in which poor nutrition damages the nerves in both the central and peripheral nervous system, and Korsakoffs Syndrome, which impairs memory, problem-solving skills and learning abilities. Severe injuries and physical trauma can also produce post-traumatic stress disorder, which can cause temporary memory loss to help a person cope with the traumatic event that caused the injury.
In the case of physical trauma, the length of memory loss depends on the severity of the injury.
How Generalized Anxiety Disorder Affects Memory
If you experience generalized anxiety disorder , you have chronic and persistent anxiety. Your friends and loved ones may describe you as “nervous” or as “a worrier.” You may feel anxious about daily situations and your worry is likely out of proportion or irrational. Anxiety can alter your everyday routines, and it can also have an impact on your memories.
Memories can be affected when you are under periods of stress or experience some sort of disturbance in mood. Having a significant anxiety disorder like GAD can create some of these problems routinely, leaving you operating below your normal level of memory functioning.

How Is Dissociative Amnesia Diagnosed
If a patient has symptoms of dissociative amnesia, the doctor will perform a complete medical history and physical examination. Although there are no laboratory tests to diagnose dissociative disorders, the doctor might use blood tests or imaging to make sure the patient doesnt have a physical illness or side effects from a medication.
If the person doesnt have a physical illness, they might be referred to a mental health professional such as a psychiatrist, psychologist or psychiatric social worker. This caregiver performs a clinical interview to get a full picture of the persons experiences and current functioning. Some psychiatrists and psychologists may use specialized tests or a standard interview such as the Structured Clinical Interview for Dissociation .
The Stress Response Changes The Electrical Activity In The Brain
Apprehensive behavior activates the stress response, which causes a number of physiological, psychological, and emotional changes that enhance the bodys ability to deal with a threat.
Some of these changes cause an increase in electrical activity in parts of the brain. Increased electrical activity causes the brain to generate an increase in thought generation and at a faster rate.
An increase in thought generation can cause our attention to be easily distracted, which can cause split attention and focus making learning and remembering difficult.

Causes Of Forgetfulness From Anxiety
Your memory is actually very fragile. Your ability to create and recall memories is related to a variety of different factors, including things like nutrition and sleep. Did you know that when we sleep, our brains use this opportunity to sort and encode many of the memories that we have made during the day? Therefore, if you’re not sleeping as result of anxiety, it’s possible that youre forgetful because your brain isnt able to properly process whats happening to you during the day.
However, there are many other potential causes of forgetfulness as well. These include:
Anxiety causes numerous changes to happen to your brain and the way you think, and all of them can lead to issues that may contribute to forgetfulness.
Causes Of Anxiety Memory Loss
The main cause of memory loss is a hormone known as cortisol. It’s the hormone released during stress, which is why those with severe anxiety are more at risk for developing memory loss problems. Numerous studies have confirmed that cortisol contributes to memory loss, especially short term memory loss, because it is a toxin to the cells of the brain.
The longer you deal with anxiety, the more cortisol you’ll have in your system, and that means that you’re more likely to continue to suffer from memory loss in the future. But cortisol is not the only culprit. Other reasons for trouble remembering include:
Memory loss may be its own cause of anxiety. People are afraid of getting older and forgetting things, so when they forget anything they start to feel as though their minds are failing them.
All of these examples of memory loss are normal, and simply a part of dealing with anxiety. In order to overcome that memory loss, you need to do two things:
- Learn Memory Improvement Tricks
- Control Your Anxiety
Memory improvement tools are always important, and when you have anxiety they’re even more so. You should be focusing on new and interesting ways to keep your memory active.
Daily blogging is one useful way. Give yourself a personal recap of your day. You don’t need to go into great detail, but you should take relevant notes of things that you want to remember and then re-read those notes often in order to keep those memories alive.

When To Seek Help
If you think there’s something else going on – and your memory problems are more serious and persistent – it may be time for a medical check-up.
“Memory problems can also be caused by an underactive thyroid gland, drinking too much alcohol, medication side-effects, vitamin B12 deficiency etc, and these can be addressed,” says Dr Graham. “They have other symptoms or clinical signs, to differentiate them from memory problems due to mental health.”
Of course, this is not to imply that mental health issues are somehow less serious than physical ones. If stress, anxiety or depression is the culprit – common at a time of COVID-19 – then getting help for this should improve your memory too.
The Truth About Memory Stress And Cortisol
In the short term, cortisol may be beneficial .
However, cortisol binds to cells in that area of the brain that converts new experiences into memory. This binding disrupts the memory-forming process, ultimately making memory impairment permanent.
Researchers at the University of Iowa also found a connection between cortisol and short-term memory loss in older rats.
Another study by Cheryl D.Conrad found that chronic stress reduces spatial memory: the memory that helps you recall locations and relate objects. Chronic stress clearly impacts nearly every brain region.
Precisely the reason you sometimes forget where you kept your car keys when you are about to rush to the office for an important meeting.
High stress also activates the release of adrenaline into the bloodstream. Adrenaline increases your attentiveness which is important to support your defense mechanism of fight or flight when put in a stressful situation.
However, adrenaline and memory do not mix well.
While the increased attentiveness may have a fleeting beneficial effect on memory the anxiety and distress that causes adrenaline production is likely to lead to brain fog and forgetfulness.
