Ptsd Memory Loss Makes Little Room In The Brain For The Little Things
Memory loss sufferers may struggle to recall small details of their daily lives. You may forget your address, medical appointments, or loved ones’ birthdays. Things that were once routine or automatically came to mind may need prompting or reminders.
If you are a parent or in a romantic relationship, it may seem callous or uncaring if you forget significant dates or events and don’t share how much you’re struggling.
What Causes Dissociative Amnesia
Dissociative amnesia has been linked to overwhelming stress, which may be caused by traumatic events such as war, abuse, accidents or disasters. The person may have suffered the trauma or just witnessed it. There may be a genetic connection in dissociative amnesia, as close relatives often have the tendency to develop amnesia.
Types Of Dissociative Amnesia
Dissociative amnesia is a dissociative disorder. Dissociative disorders are a type of mental illness. Theyre characterized by disconnect between things like your memories, identity, and surroundings.
If you have a dissociative disorder you may feel disconnected from the world that surrounds you. Periods of dissociation can last for hours or days and in some cases can last longer for weeks or months.
There are a few different types of DA:
- Localized. This is where you cannot remember events from a specific time period.
- Generalized. This is a complete loss of memory, including things like identity and life history. Its very rare.
- Fugue. In dissociative fugue you forget most or all of your personal information and may wander or travel to places you wouldnt usually go. In longer-lasting cases, you may even take on a whole new identity.
DA can be characterized by the following:

Why Is Memory Affected By Ptsd
In essence, the brain takes on a huge effort trying to sort, calm and organize the traumatic memories that led to the stress disorder. In addition, the brain also attempts to recall and store a constant, stream of daily input.
Its no wonder that the PTSD memory loss suffered by trauma survivors only serves to further heighten anxiety and frustration as they try to relate to others and interact with the present world.
Often, their minds are repeating past, traumatic information in ways that are too overwhelming to distinguish quickly. So, as past mental and sensory memories intrude on the present, via flashbacks, nightmares, etc. they may concentrate heavily on avoidance or overreact to the memories. Over time, the memory distortion and losses add up, causing a confusing blend of upsetting, incomplete impressions about their pasts and the present moment.
Unfortunately, those that care about them may feel confused and hurt as well, uncertain of how present or emotionally available their loved one can be.
How Ptsd Impairs Learning And Memory
Most people associate post- traumatic stress disorder with anxiety, anger, and, at its worst, suicide. But one of the most pervasive symptoms of PTSD is not directly related to emotions at all: individuals suffering from a stress-related disorder experience cognitive difficulties ranging from memory loss to an impaired ability to learn new things.
One of the most crucial cognitive deficits of PTSD involves how we handle new experiences and fold them into the fabric of memory. Its called pattern separationliterally, the brains way of separating similar experiences, places, and events.
Even though I may remember 9/11, when I see an airplane over New York City, I am able to recognize that its a different situation and process it accordingly. Someone in the same situation who has PTSD may re-experience the traumatic events of 9/11 and have a panic attack, said Rene Hen, a Columbia University Medical Center researcher. Dr. Hen recently led a study showing that boosting the number of neurons in the adult mouse brain led to improved pattern separation.
The area of the brain that Hen targeted in his studythe hippocampusmay be where the seemingly disparate areas of learning and mood come together. Both Hens research and a new study led by Dr. Andrew R Marks may contribute to potential treatment for PTSD and related anxiety disorders.

What Part Of A Persons Memory Is Altered By Trauma
Trauma seems to be specifically linked to a persons autobiographical memory. Autobiographical memory is part of our explicit memory and helps us remember the things that have happened in our life and the world around us. This form of memory allows you to develop a logical understanding of the flow of life.
But because your memory of the trauma isnt as consistent as normal autobiographical memories, researchers think this is where the problem lies. Your memory of the trauma is broken, fragmented. It may even feel separate from your life. Because it feels foreign to you, you end up experiencing it as intrusive.

Ptsd Changes The Brain’s Memory Centers
“PTSD has been linked with changes to brain structures that are implicated in the processing of strong memories, including the hippocampus and amygdala,”Sean Clouston, Ph.D., an associate professor of public health at Stony Brook Medicine, tells Bustle.
Specifically, research has found that PTSD affects the parts of the brain that process experiences in context, including the hippocampus and the prefrontal cortex. Dr. Israel Liberzon, M.D., head of the Department of Psychiatry at Texas A& M University and a PTSD researcher, tells Bustle that according to a study published in Biological Psychiatry in 2018, people with PTSD have smaller hippocampus volume, and that different centers in their brains don’t communicate efficiently.
Ptsd And Traumatic Memories: Whats The Connection
ScienceDirect explains that traumatic memory plays a central role in the criteria used to diagnose PTSD. It also cites research that shows memory capacity, contents of memory, and memory processes that are affected by traumatic events could transition to the development of PTSD.
Helping people manage their traumatic memories is essential to treating the disorder. Traumatic memories can be formed after an experience boosts stress hormone levels and emotional arousal levels. WebMD writes that stressful events can create bad memories that are challenging to forget.
The theory: In stressful situations, the stress hormone norepinephrine may prime the brain to remember what happened in order to avoid the same threat in the future, according to the health site.
Another challenge traumatic memories present is that they are not always realized by or accessible to the people who have them. This group includes those who have not been formally diagnosed with PTSD.
Not being able to tap into distressing memories makes it harder for some people to connect their inability to function to the trauma loop they are stuck in. They are experiencing stressful events repeatedly without knowing it.
A 2015 Northwestern University report states that traumatic memories hide in the brain like a shadow. It goes on to say that, At first, hidden memories that cant be consciously accessed may protect the individual from the emotional pain of recalling the event.

Memory Types And Bipolar Disorder
Many people with bipolar disorder are extremely bright, so memory or other thinking problems can be extremely frustrating and confusing.
1. Bipolar disorder and the loss of semantic memory:
Semantic memory is a long term memory of facts, definitions of words, and other concepts that make up our general knowledge about the world.
Studies do not show a link between bipolar disorder and loss of semantic memory. For example, even during a profound episode of mania or depression, we are likely to remember that London is in England, that ducklings grow up to be ducks, and that a dictionary contains definitions for words.
2. Loss of sensory memory and bipolar:
Sensory memory is the retention of stimulus received through our senses of sight, hearing, smell, taste and touch. Sensory perception is sometimes disturbed during bipolar disorder for example, the hallucinations experienced in bipolar psychosis.
A national study of over 14,000 bipolar patients found the lifetime prevalence of psychosis in manic and depressive episodes to be 19% and 15%, respectively.
However, this is not the same as a loss of sensory memory. Research in this area is lacking, but it seems that bipolar disorder does not interfere with how we remember the smell of roses, the color of the sky, or the softness of our favorite sheets.

Ptsd Memory Loss Compromises How Well You Interpret Current Place And Time
Meaning, your ability to calm and soothe yourself in places that remind you of your trauma may be affected. Do you feel triggered even when there is the slightest reminder of your experience in a setting?
Therefore, this problem of sorting out environmental context is related to your reduced capacity to limit the flood of old memories.

Memory And Trauma: What’s The Link
28 May, 2020
There have been many studies aimed at figuring out what trauma or intense emotional experiences can do to the way a person classifies, stores, and retrieves memories. Is there a link between memory and trauma? Can traumatic memories leave a bigger mark on you than regular ones?
Some people say that we process traumatic experiences differently than we do normal ones. That difference would come in the form of an altered memory thats harder to retrieve. But other people say that stress doesnt alter the quality of memories and that we process them in a similar way.
People have based these positions on lab studies. The truth is that its hard to reproduce trauma in a controlled, safe environment. The best means we have of studying this is by analyzing people with post-traumatic stress disorder . The idea is that their experience is a good place to start studying the link between memory and trauma.
Why Its Important To Treat Ptsd
PsychCentral writes that many people who survive trauma struggle with what comes after the experience because they dont understand the biological changes the brain and body go through and what that process means for how their lives will be affected and how the condition can be treated.
The biological changes are worsened by what it says are three major brain function dysregulations, which are:
An overstimulated amygdala: This mass is located deep in the brain and is responsible for tagging memories with emotion and identifying survival-related threats. Once trauma occurs, it can remain in high alert and look for threats everywhere.
Underactive hippocampus: This part of the brain becomes less effective at making synaptic connections needed for memory consolidation because an increase in glucocorticoid, a stress hormone, kills cells in that area. This break in communication keeps the body and brain in reactive mode because it is not aware that the distressing event has passed.
Ineffective variability: Elevated stress hormones keep the body in a state where it cant regulate itself. As a result, the sympathetic nervous system remains highly activated, which can keep the body and its systems fatigued.
All of these dysregulations illustrate why getting help for post-traumatic stress is in the best interest of the person who is living with it.

How Acute Covid Infection Affects The Brain
An acute infection is a sudden and active infection. According to NINDS, COVID probably does not infect the brain or nerves directly. Inflammation and damage are caused by proteins called antibodies that the immune system makes in response to the infection. These antibodies may cause a severe immune system reaction that could cause brain or nerve swelling. There are also other ways COVID can cause neurological symptoms:
- COVID mainly affects the lungs and causes oxygen levels to drop. The brain and spinal cord require oxygen to function. Low oxygen levels can cause damage to the central nervous system. Without oxygen brain cells start to die.
- Some research shows that COVID viruses can attack the cells in the walls of blood vessels and make them weak. This can cause microbleeds. In the brain, these microbleeds lead to mini-strokes.
- COVID may also increase the risk for blood clots. A blood clot in a blood vessel that supplies part of the brain can also cause a mini-stroke.
- A large bleed or large blood vessel clot in the brain can cause a full-blown stroke with permanent brain damage.
Common COVID symptoms dont typically include neurological symptoms, but brain fog and memory loss can occur because of long COVID.
Is There Any Covid Brain Fog Treatment
Until we have more time and more studies, there are more questions than answers. We dont know how long brain fog lasts after COVID or how long fatigue lasts after COVID. Until we know more, there is no known treatment for long COVID neurological symptoms. The best thing to do is tell your doctor about your symptoms and work with your doctor to find what works best for you.

How Does Hypothyroidism Affect Memory
Thyroid hormones help to regulate many aspects of bodily function, including mood, energy levels, and cognitive performance. When levels are low, as is the case with hypothyroidism, these functions can be impaired. This can lead to problems with memory, focus, and thinking skills.
Many of the symptoms of hypothyroidism are very similar to those experienced by people who are experiencing early stages of dementia. Memory loss is often one of the first symptoms, so being able to recognize hypothyroidism early can be beneficial in terms of establishing a proper treatment plan.
People who have chronic medical conditions or have suffered an injury may experience memory loss. Hypothyroidism can cause mild cognitive impairment, which may look similar to memory loss caused by other conditions. With this in mind, its important that patients visit their doctor for regular checkups and comprehensive testing if they are experiencing any symptoms. This will not only help you identify whether you have hypothyroidism but also rule out any other potential causes for your symptoms.
Core Symptoms Of Ptsd: Flashbacks
Some of the biggest, most limiting symptoms of PTSD include things such as avoidance, bottling up emotions, hyperactivation, re-living events, and intrusive memories.
Those last ones all involve some form of re-living a traumatic event in a persons life. This could happen through nightmares, intrusive memories, or flashbacks.
That these things happen doesnt mean this person doesnt still have gaps in their memory. They still cant remember certain parts of what happened. But certain details or scenes may flash clearly into their mind for a brief moment. The big problem with this is that these flashbacks are uncontrollable and unavoidable for them.

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.
Persistent Sadness And Being Suicidal
Complex trauma survivors often experience ongoing states of sadness and severe depression. Mood disorders are often co-morbid with complex PTSD.
Complex trauma survivors are high risk for suicidal thoughts, suicide ideation and being actively suicidal. Suicide ideation can become a way of coping, where the survivor feels like they have a way to end the severe pain if it becomes any worse. Often the deep emotional pain survivors feel, can feel unbearable. This is when survivors are at risk of developing suicidal thoughts.

Some Statistics About Ptsd And Its Link To Memory And Trauma
The basic definition of PTSD is that its an irregular response people have to a traumatic, devastating, or painful experience. Referring to it as not normal is a mistake, though. In the end, these are reactions from normal people to things that have never happened to them before.
An inability to confront that memory leads people to experience intrusion symptoms related to the original event.
Those symptoms include things such as recurring, anxious memories, dreams, nightmares, dissociation , psychological discomfort, avoidance of anything that has even the smallest relationship to that experience, and intense physiological responses.
The most common causes of PTSD are things such as natural disasters , accidents, and illnesses. But theres one thing that gives people a 70-80% chance of developing it: human atrocities. That includes everything from assault, terrorism, sexual abuse, rape, and concentration camps.
Connection Between Brain Injury And Memory Loss
Your cherished memories can all but disappear through a particularly hard blow to the head or by falling and striking your head on a hard surface. Memories of your childhood, your first kiss, first love, graduation or wedding can all be erased in a single instant of violence or calamity.
This article will look at the connection between a brain injury and memory loss, the different types of memory loss and whether or not there is a chance that these memories will ever return.
