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.
When Its Time To See A Doctor
If youre not sure if loss of memory warrants a doctor visit, consider:
- Does your memory loss disrupt daily activities?
- How often do the lapses occur?
- Whats being forgottendetails of a conversation, or the conversation in its entirety?
- Are there signs of confusion ?
- Is the memory loss getting worse?
If someone is having trouble remembering the day of the weeknot the date, but Monday, Tuesday, Wednesdaythats concerning, says Dr. Karlawish. Other concerning signs are repetitive questions: They get an answer, then several minutes later, they ask the same question. Or they repeat a story: something about a recent event, but then 20 minutes later, they tell you the same story.
Its not unusual for people to deny theyre having memory problems or to downplay the issue, but a prompt diagnosis is important.
Arrive at some reasonable, common understanding that you ought to get it looked into, says Dr. Karlawish. They dont have to agree on everything youve seen, and you dont have to make it a confrontation. Just get to the point where you can agree that Gee, it would be good to get this checked out. Then, the key is to go with them to the appointment.
You dont need to find a specialist for an initial consultation. Instead, look close to home.
Start with a doctor who knows you well, so a primary care physician, says Dr. Karlawish. Ideally, people go in with someone who knows them wella spouse, child or close friendwho can speak to what theyve been seeing.
The Answer Is A Big No
Because, in general, stress impairs memory, makes you forget things or even remember things differently.
Ben, for instance, could recall the thiefs face vividly for a day or two but after a few weeks, he couldnt picture the guys face at all.
And keep in mind that Bens no dummy.
Hes not only an author, but also someone who happens to be an independent researcher who studies consciousness and the brain.
High IQ or not
When were stressed, some memories stick like super glue while others get warped or lost.
For that reason, please understand this:
Its never a good idea to induce stress when trying to memorize a book, your lessons or your campaign presentation.
You never know what essential information your brain will skip remembering!
Instead, increase focus and concentration from the ground up using a WRAP technique:

Different Types Of Memory
On a daily basis, we rely on a variety of types of memory. Here are brief descriptions of the different types of memory, how long they last, and the brain regions involved.
- Sensory memory: This lasts less than 1 second and is usually lost since it is not encoded. It is associated with the visual-sensory cortex in the parietal/occipital lobes of the brain.
- Short-term memory: This lasts less than 60 seconds, such as remembering a phone number, and involves the prefrontal cortex.
- Working memory: This lasts seconds to hours, such as cramming for an exam and is associated with the prefrontal cortex.
- Long-term memory: This lasts hours to months and involves the hippocampus. Long-term memories pass through the hippocampus then are stored in various regions throughout the brain. For example, visual cues are stored in the occipital lobes, sensory cues are stored in the parietal lobes, sounds are stored in the temporal lobes, and so on.
- Long-lasting memory: These memories last months to a lifetime and are processed in the hippocampus before being stored all over the brain.
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.

What Does Anxiety Do To Memory And Why
First and foremost, anxiety is unlikely to cause you to wake up with complete amnesia. It doesnt seem to affect long-term memory. Its your working and short-term memory that is at risk of being enslaved by anxiety. Anxiety is a never-ending loop. People who suffer from it frequently feel stuck in their thoughts, continually replaying possible events that have yet to occur.
This also causes hypervigilance. Because anxiety hypervigilance loops may last an endless amount of time, being caught in one can be highly psychologically exhausting. In addition, these hypervigilance cycles can lead to cognitive exhaustion, resulting in memory loss in certain people.
Theres a reason why moderate anxiety-related memory loss is referred to as brain fog. You could forget things like instructions, how to do work, conversations youre sure you had, engagement and deadline dates, the material youve just read, and so on. Anxiety-forgetfulness is frequently accompanied by feelings of perplexity, dissociation, and concentration difficulties.
There are several neurobiological causes for anxietys interfering with short-term memory:
Hang Out With Friends
Even better than just seeing a funny movie, is seeing one with friends. Surrounding yourself with happy people makes you feel happier too. Try joining new groups or reconnecting with old friends. Limit time spent on social media if you find that negative posts appear more often than positive stories.

Affect Of Depression On Our Brain
Depression decreases the volume of gray matter in the human brain. A paper published in 2013 highlights detailed changes in the brain from depression. This affects focus, behavior and triggers bad memories. Depressed people find it difficult to monitor their behavior. They often remember the negative traits of people more.
How Can You Help A Loved One Whos Experiencing Grief And Memory Loss
When your loved one’s grieving, the memory loss they experience can make them feel like they’re losing their mind. Not many people link memory loss to the natural and expected part of the grieving process. Widespread side effects might include losing your train of thought mid-sentence or forgetting what you were doing even as you’re doing it, leaving you feeling lost and disoriented.
Forgetfulness, confusion, and the inability to focus are all normal grief responses. The following are ways to help someone who’s experiencing grief-related memory loss get back on track.

Can Depression And Anxiety Cause Memory Loss
It comes as no surprise that depression and anxiety make you feel sad, bad, and stressed. But many people are unaware that these mental health issues are also associated with forgetfulness, poor concentration, trouble making decisions, and confusion. It all adds up to memory problems, and thats bad news. How do anxiety and depression interfere with memory? Before diving into the details, lets take a look at how memories are made and the different types of memories.
The Effect Of Acute Stress On The Memory
Most findings regarding acute stress have actually found them helpful to memory formation, unlike chronic stress.
This is because the response by the brain to an acute stressor is not ongoing and the cortisol effect on it is brief. A small amount of cortisol in the brain-memory connection can actually be helpful to memory formation.
The list below explains the effects of acute stress on memory:
1. Some studies have shown that acute stress enhances memory formation while impairing memory retrieval.
2. Acute stress is often accompanied by emotional stressors, so the signals from these stressors are sent to an emotional processing area of the brain called the amygdala, and also, it is sent to the hippocampus. The amygdala, excited by emotions, probably communicates with the hippocampus to take note of that information, and this causes memory formation.
Previous research works have suggested that emotional experiences can strengthen memories.

Many people wonder whether stress is linked to risk of dementia, and the news often reports a link between the two. This Stress Awareness Month, our Research team decided to examine the evidence behind stress and risk of dementia.
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 .

Effects Of Stress On Memory
The effects of stress on memory include interference with a person’s capacity to encodememory and the ability to retrieve information. During times of stress, the body reacts by secreting stress hormones into the bloodstream. Stress can cause acute and chronic changes in certain brain areas which can cause long-term damage. Over-secretion of stress hormones most frequently impairs long-term delayed recall memory, but can enhance short-term, immediate recall memory. This enhancement is particularly relative in emotional memory. In particular, the hippocampus, prefrontal cortex and the amygdala are affected. One class of stress hormone responsible for negatively affecting long-term, delayed recall memory is the glucocorticoids , the most notable of which is cortisol. Glucocorticoids facilitate and impair the actions of stress in the brain memory process. Cortisol is a known biomarker for stress. Under normal circumstances, the hippocampus regulates the production of cortisol through negative feedback because it has many receptors that are sensitive to these stress hormones. However, an excess of cortisol can impair the ability of the hippocampus to both encode and recall memories. These stress hormones are also hindering the hippocampus from receiving enough energy by diverting glucose levels to surrounding muscles.
What Happens If You Experience Grief And Memory Loss
The death of a loved one can always be one of the most stressful events in life. Temporary memory loss associated with trauma, loss, or grief is a side-effect of bereavement that can lead to dysfunctional grief when left untreated.
Jump ahead to these sections:
This type of grief is also known to take a toll on your physical and mental well-being, with the deterioration of your memory being a significant byproduct of ongoing distress.
So how can you avoid having memory loss when dealing with grief and anxiety? It helps when you understand how grief affects your memory and daily cognitive functions. Below, youll find information on why you experience grief-related memory loss and how you can avoid some of the most common pitfalls.

When Should You Worry About Frequent Forgetfulness
Weve all been there. You know what you want to say, but cant remember the word. You forget the name of a favorite movie. Youre about to leave for an appointment, but you cant find your car keys or phone.
Forgetting why you walked into a room on occasion, difficulty recalling the name of someone you just met or having a word on the tip of your tongue that later comes to you is typically not concerning, said Lyndsay Mentgen, APRN, with OSF HealthCare Illinois Neurological Institute. However, if memory loss starts to affect daily functioning for example, missing appointments or forgetting to take medications further evaluation is recommended.
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.

Concussions And Head Injuries
Concussions and traumatic head injuries can cause short-term memory impairment, but some research has found that they can also increase the likelihood for the development of dementia over the years.
Be sure to take steps like wearing protective headgear and helmets when playing sports. And, if you do sustain a concussion, it’s important to let your head fully heal before returning to regular activities and participating in sports. Discuss any headaches and concentration difficulties after a head injury with your doctor.
How To Cope With Memory Loss
Memory loss due to depression is usually treated with regular counseling or antidepressant therapy. An active lifestyle and community involvement can also improve your mood, treat depression and bring you towards a healthy life. If things are getting out of hand, then you can also consider help from your family doctor. Do consider joining a support group as well.
There are also drugs that can improve memory loss in people with Alzheimer’s disease or other neurological disorders.

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.
The Capacity Of Short
Your short-term memory has a limited capacity. Certain studies conducted by the famous George Miller in the 1950s are often used as the guideline for determining how much capacity the short-term memory has. It is estimated that working memory can hold five to nine items at a time. However, newer studies have shown that in different age groups, the number is much lower, around four to five items.
The type and characteristics of the information also make a difference in how much can be stored in short-term memory. There have also been studies that have shown that short-term memory capacity and how long information remains in short-term memory can be increased if the information is said aloud.

How Anxiety Can Cause Memory Loss
Anxiety can definitely cause memory loss. Here are three reasons that anxiety can cause memory loss:
- Stress Hormones The stress hormone cortisol is often elevated in patients who have General Anxiety Disorder. Cortisol elevation can help create a memory in a stressful situation, but it makes it more difficult for a person to recall an existing memory. It is not believed that these memory problems are permanent or represent any type of loss of brain function. When the stress diminishes, your normal ability to recall memories will return.
- Distracted Thinking People with anxiety are also prone to having incredibly active minds with lots of thoughts running through their mind. When your mind is this active, you are not focused on the new things you’re trying to remember, which distracts you from forming a memory. Distracting thinking also blocks your ability to become aware of memories when they appear in your stream of consciousness. It is like clouds blocking your ability to see the sun.
- Sleep Loss, etc. – Anxiety also affects secondary issues which may affect memory. For example, anxiety can make it harder to sleep, and sleep deprivation has a known effect on memory and recall.
The Stress Hormone: What You Need To Know
If anyone tells you you need to know about a stress hormone in the human body, they are probably talking about cortisol. Cortisol belongs to a class of stress hormones called the glucocorticoids .
Cortisol is produced in the adrenal glands, just above the kidney, and it is the most well-known and probably the most studied stress hormone.
In fact, cortisol is a popular biomarker for stress.
Cortisol is released when the body is under stress, and because most cells in the body have cortisol receptors, it affects many different functions in the body. Cortisol can control blood pressure, heart rate, blood glucose and muscle tension in response to stress. It can also facilitate and impair the actions of stress in the brain memory process.
To illustrate this, when cortisol is produced in excess, it can impair the ability of the hippocampus to form and recall memory, especially long-term memory. Note that the hippocampus plays a great role in converting short-term memories to long term memories.
The process that can make cortisol impair the functions of the hippocampus is quite ironic, since the hippocampus itself can regulate the production of cortisol under normal circumstances . But when the hormone is already produced and continues to be produced in excess, it can overwhelm the hippocampus and impair its job of forming and recalling memory!
