How Exactly Does Anxiety Takes A Toll On Your Memory
Anxiety is a stumbling block. If you already suffer from anxiety, then you already have an idea about the trouble it can cause. Your worries about things that you have no control of can occupy your thoughts to the point where you start living with them. You cant escape them even if you try.
Worries and anxieties will eventually become a part of your daily routine where you will be constantly worried about reaching on time, pairing the right jeans with a top, or adding the right amount of spice to your dinner. Whatever you do, anxious thoughts are there for you to be managed at the same time. It makes it difficult to pay full attention to what you want to focus on.
As you continue to focus on the reasons behind your worries, your brain will start shifting its focus towards the potential threats in normal life situation to keep you safe. You might wont leave the kitchen while boiling the milk just because you feat that it will spill if you dont take it off the stove on the right time.
This makes it impossible for the brain to process additional information, and it begins to fade. Once you realize that you have been missing some important things, you might wonder if something serious is going on. This might increase your worries and make the situation even worse.
What Is The Relationship Between Stress And Memory Loss How Are They Connected
Stress and memory loss relationship is quite strong and directly related to each other. As a part of the human body that has a strong impact on our nervous system, an acute amount of stress and anxiety can damage our memory and basic learning functions. So, this is the main evidence that proves that anxiety and stress are strongly associated with each other.

How Anxiety And Memory Loss Are Connected
The stress response sheds light on how repeated anxiety can lead to memory loss. When your body reacts to real or perceived threats, electrical activity in the brain increases and produces adrenaline and cortisol. Memory loss can result if that process occurs when fear or anxiety is excessive or persists beyond developmentally appropriate periods. Thats because anxiety and stress tax the bodys resources.
Research like the study published in Brain Sciences acknowledges the relationship between high levels of anxiety and memory loss. One study in the International Journal of Geriatric Psychiatry found that anxiety disorder is interrelated and inseparablewith loss of memory. It added how anxiety is likely an early predictor of future cognitive decline and possibly future cognitive impairment.
There is still a great deal to learn about the connection between anxiety and memory loss, which is an ongoing research topic. For instance, thanks to a first-of-its-kind study, there is now evidence that acute stress disrupts the process behind collecting and storing memories. Researchers found that short-term stress-activated certain molecules that in turn limit processes in the brains learning and memory region. As a result, given the link between anxiety and stress, both long-term and short-term anxiety can impact memory.
The Toll Of Anxiety And Stress On Memory
Similarly, anxiety and chronic stress have been associated with memory problems, according to research in Neurology and BMJ Open. Brain circuits involved in chronic anxiety and fear overlap those seen in Alzheimers disease. In addition, chronic stress shrinks volume in the hippocampus. One study in the International Journal of Geriatric Psychiatry found that anxiety is inter-related and inseparable with loss of memory. The researchers suggested that anxiety is an early predictor of cognitive decline. Whats behind this strong link?
In general, anxiety requires a lot of mental horsepower and steals mental energy from the memory formation process. Spending so much time stressing about things means you may not have the brainpower to effectively process incoming information for storage as memories. For example, a 2008 study found that short-term, acute stress interferes with cell communication in the brains memory centers.
Because of this, it is critical that you learn to control anxiety and stress. Take note that brain SPECT imaging studies show that some anti-anxiety medications, such as benzodiazepines, are actually harmful to the brain. In fact, a 2019 review in the Journal of Clinical Neurology found that long-term use of these prescription drugs increases the risk of dementia by more than 50%. For better brain health, look for natural alternatives to anti-anxiety pills to calm anxiety and stress.

Infections Of The Brain Or Its Lining
Infections like HIV, tuberculosis and herpes can cause memory problems. HIV puts the function of nerve cells at risk by infecting the cells that protect and support them. The virus can also trigger inflammation that can damage the brain and cause forgetfulness. With tuberculosis, memory loss can be a complaint. However, prompt treatment can resolve these problems. Meanwhile, herpes simplex virus can cause a rare neurological disorder called herpes simplex encephalitis. This inflammation of the brain can lead to memory loss. Antiviral drugs may help if treatment is started right away.
Do Panic Attacks Cause Memory Loss
Panic attacks are a common symptom of panic disorder . Panic-related memory loss happens for a few reasons similar to those youve just read.
These are more likely to affect the memories leading up to, during, and directly after the panic attack. They dont tend to be total. Folks usually remember having the attack, but the details and specifics outside of feeling ahhhhhhhhhhhhhhh are vaguer than a Senate floor filibuster.
Continuing the theme of anxiety being terrible, having panic attacks can lead to intense anxiety about having panic attacks. This in turn causes more memory loss. Its the circle of life, but instead of musical cartoon animals, we get terror and confusion.
If youre prone to hypochondria, its best not to get too caught up in the other possible causes of memory loss. But a lot of these conditions are pretty serious. You should speak with your doctor if your memory loss symptoms dont get better or actively become more severe as your anxiety clears up.

How Can Stress Cause Memory Loss
When we are stressed, our adrenal glands produce more cortisol, one of the bodys key stress hormones. The cortisol shuts down bodily functions that may get in the way of survival until the crisis has passed.
The problem is that if we stay in a state of stress, our bodies do not return to normal. If we want to know what causes memory loss, we have to look at chronic stress and what it can do to the brain.
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.

Neurobiological Mechanisms Involved In Deleterious Effects Of Chronic Stress On Brain And Behavior
First, it is important to note that the mechanisms whereby chronic stress impairs cognitive function are not necessarily the same as the ones mediating acute stress effects. While neural alterations involved in acute stress effects seem to be mainly mediated by dynamic functional alterations among cellular and molecular interactions, chronic stress is now known to have a major impact on both functional aspects and neuronal structures. In this section, the main structural and functional effects of chronic stress on specific neural circuits will be discussed, followed by an overview of the molecular processes reported to contribute to such effects.
12.1.7.1. Structural Effects of Chronic Stress
Because many examples in the literature indicating impairing effects of chronic stress in memory processes were obtained in hippocampus-dependent tasks, the hippocampus is the brain region that has received the most attention. However, intensive work during the past few years is providing increasing evidence for a more integral impact of chronic stress throughout the brain that, as illustrated below, is now documented to a certain extent at the level of the prefrontal cortex and amygdala.
Hippocampus
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.

Why Has Stress Been Linked To Dementia
There are many logical reasons why stress could be linked to dementia. Stress affects the immune system, which is known to play an important role in the development of dementia.
A key hormone released when youre stressed, cortisol, has been linked to problems with memory. Stress is also closely linked to conditions such as depression and anxiety, which have also been suggested as factors that could increase the risk of dementia.
Some research has found that stress appears to have a direct impact on some of the mechanisms underlying dementia in animal models.
However, as with many things in the research world, understanding whether any of these theories are correct has turned out to be a long and winding road.
Common Signs Of Anxiety
Anxiety doesnt work like depression as you don’t forget the key events in your life, but it generally affects working memory. You can retain instructions, directions, conversation, or your exam material. You are unable to remember and focus on minor details due to anxiety.
The constant struggle that your mind does to keep it out of stress leads to forgetting little things and significant events, resulting in conflicts and tension. You will also feel trouble carrying out daily essential tasks like cooking or driving as you might forget to keep turn the gas off or the fear of missing the right turn wont let you focus on other road details.

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.
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.

Panic Attacks And Memory Loss
Some people who have panic attacks find it difficult to recall what happened just before or during an attack. Panic-related memory loss can happen for some of the same reasons that general anxiety leads to memory loss.
Panic attacks brief episodes of extreme fear are a type of anxiety. They come on quickly, often without warning, triggering symptoms that can feel overwhelming and terrifying:
- difficulty breathing or feelings of choking
- pounding or racing heart
- numbness, tingling, or blurred vision
- feeling of doom
- feeling of losing control
Some people having a panic attack might believe theyre dying or having a heart attack. You might feel totally preoccupied by these unpleasant feelings, lose track of time, and think about nothing except getting through the attack.
Afterward, you might recall the intense panic vividly, but you might not recall exactly how you made it through.
If youve had a panic attack before, you might also worry about having one again, especially when you find yourself in a situation that triggers feelings of worry or fear. When this increase in anxiety occupies your focus, you might also notice some memory trouble.
Memory loss can happen for plenty of reasons.
A few of the other potential causes include:
- regular alcohol or substance use
- side effects of certain prescription medications
Even when you live with anxiety, other concerns can contribute to memory loss, so its important to monitor your difficulty remembering things.
What Causes Stress And Memory Loss
Stress is caused by various factors and influenced by genetics and the environment. Any challenge in life, no matter what form it takes, can cause stress. Acute stress is experienced when faced with a suddenly threatening situation, such as a car accident. The body pumps out cortisol and then returns to normal once the threat has passed.
Chronic stress occurs when stress is experienced over an extended time period, such as when living with a chronic illness, experiencing financial troubles or conflict in a relationship. This is typically the type of stress that leads to health problems, such as memory loss.

What Stress Can Do To Your Brain
The brain is particularly vulnerable to stress because of all the nutrients and oxygen it needs to function optimally. When the body is using those resources to deal with stress, the brain has access to less of them.
A new study published in the journal Neurology looked at men and women with an average age of 48. The researchers gave more than 2,000 people with no signs of dementia various psychological tests to measure thinking skills. The participants were all part of a long-term study, the Framingham Heart Study, which has followed the health of Framingham, Massachusetts, and their children since 1948.
The whole group was reevaluated eight years after first being tested. The level of cortisol in the blood was measured, brain MRIs done and cognitive tests were repeated. The data was adjusted to take sex, age, smoking, and body mass into account. It was found that those with the highest levels of cortisol experienced the most memory loss.
What was different about this study is that MRI brain scans were done of the whole brain whereas previous studies focused on the hippocampus, the memory area of the brain. This study also focused on people in mid-life whereas others focused on the elderly.
Researchers found that higher levels of cortisol seem to predict brain size, brain functions and performance on cognitive tests. They also found evidence of brain shrinkage in young people before any memory loss symptoms could be seen.
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.
