Cognitive Examination Of Emotional Memory
Among 18 reports, 11 studies reported differences in emotional memory between PTSD patients and control groups.
To summarize, among these seven free recall studies, four suggest that PTSD is associated with specific emotional memory, while another observed that PTSD and TE are associated with specific emotional memory , and the two other studies did not find specific emotional memory performance in any group . Overall, during a recall task, PTSD patients seem to memorize more negative information, whether this negative information is directly related to the trauma or is generally negative . This negative memory facilitation could be due to attentional bias, which generates focused attention on negative and trauma-related words for PTSD sufferers . Indeed, PTSD patients seem to have difficulties in avoiding the memorization of negative stimuli that would underlie an inhibition deficit for negative information .
Three other studies used cued recall tests: either word-pair tasks, word-stem completion tasks, or both. These studies also produced contradictory results. A study found that PTSD and HC have the same emotional memory performance and two studies found a greater memory for negative information in PTSD groups .
This memory bias and difficulties in disengaging attention could also be interpreted as a reduction of the inhibition capacities specific to negative information.
What Kind Of Trauma Causes Memory Loss
Trauma refers to an emotional response to any significantly distressing event or incident.
Whats significantly painful to you may not be the same as whats significant for somebody else. So, the traumatic experience that leads to memory loss may be different for everyone.
Not every traumatic experience leads to memory loss. This effect may vary based on factors such as:
- your mental health status at the moment of the event
- the support you received immediately after the event
- your emotional resources at the moment of the event
- the intensity and length of the incident
What Is The Outlook For People With Dissociative Amnesia
For most people with dissociative amnesia, memory eventually returns, sometimes slowly and sometimes suddenly, which makes the overall outlook very good. In some cases, however, the person is never able to fully recover their lost memories.
To improve a persons outlook, its important to treat any dissociative amnesia problem as soon as possible. It is also important to treat any other problems or complications, such as depression, anxiety or substance abuse.

Emotional/psychological Childhood Trauma And Memory Loss
Emotional memory loss can be your way of natural survival to protect yourself from psychological damage. You may experience something called dissociative amnesia.
Dissociative amnesia is a condition where you are unable to remember important information about your life. Your amnesia can either be limited to certain times in your life or can be general . You will experience greater memory loss with dissociative amnesia than you would with normal forgetting.
Dissociative amnesia can either be mild or severe. If you have severe dissociative amnesia it can keep you from being able to function . Dissociative amnesia can also affect your relationships.
Dissociative amnesia is associated with traumatic events because you may forget or block out a memory from the trauma. For example, if you were sexually assaulted, you may not remember specific details of the assault.
Dissociative amnesia is temporary and you may eventually begin to remember details of your past trauma.

Memory And Ptsd Frameworks
There are two primary frameworks for understanding memory impairment in PTSD. The first posits that memory deficits are a product of neurobiological abnormalities caused by PTSD. The second framework posits that preexisting memory deficits serve as a risk factor for the development of PTSD following trauma exposure. Each model represents either end of the nature vs nurture paradigm – either that the environment impacts neurobiology or that, genetics influence one’s predisposition to PTSD.

Brain Exercises For Better Memory
People who have PTSD may keep their memory and higher brain functions in a healthy state by using daily mental exercises. Some brain exercises to consider include:
- Recall testing by memorizing a daily grocery list or route to work.
- Switch up and use your opposite hand, or whichever is weaker. Switching to a non-dominant hand is difficult and requires mental focus.
- Mental math, drawing a map from memory or reading books aloud.
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.

Neurobiological Abnormalities In Ptsd
Researchers have established multiple neurobiological systems and structural and functional abnormalities involved in PTSD.31–32 Here, key systems and structures and their relationship to declarative memory will be briefly summarized. Memory deficits appear to be most related to abnormalities in the hippocampus and hypothalamic-pituitary-adrenal axis, and the prefrontal cortex and catecholamine system.
Over 15 years of PTSD research has focused on the role of the hippocampus, a brain area particularly sensitive to the effects of stress. Studies showing glucocorticoid toxicity in the hippocampus and memory dysfunction in animals under stress33–34 led to the hypothesis that severe stress, in particular traumatic stress, may result in similar changes in humans. Meta-analyses35, 36 of adults with PTSD reveal smaller hippocampal volume in both the left and right sides. Functional imaging studies have demonstrated abnormal cerebral blood flow to the hippocampus37, 38 during declarative memory tasks. Other studies have found reductions in N-acctyl aspartate , a marker of neuronal integrity.39, 40 In addition, dysregulation of the hypothalamic-pituitary-adrenal axis is associated with PTSD.41–45
The Arrest And Initial Trial
On November 10, 1995, Judge Gabrielle Kirk MacDonald confirmed the indictment of Anto Furundzija, a Croatian paramilitary soldier, charging him with grave breaches of the Geneva Conventions and violations of the laws and customs of war . Mr. Furundzija was charged with three individual counts of: torture and inhumane treatment torture and outrages upon personal dignity, including rape. These charges were linked to acts alleged to have been committed at headquarters of the âJokers,â a special unit within the armed forces of the Croatian community of Bosnia-Herzegovina, known as the Croatian Defense Counsel, or HVO. In her decision, Judge MacDonald ordered that there be no public disclosure of the indictment.
Mr. Furundzija was arrested on December 18, 1997, by members of the International Stabilization Force, also known as SFOR. He was immediately transferred to The International Tribunal and detained in its detention unit in The Hague, The Netherlands. The same day, the president of the Tribunal assigned the case to Trial Chamber II. The initial appearance of the accused was on December 19, 1997. The accused was represented by Mr. Srdjan Joka, a member of the bar of the Republic of Croatia, who rendered a plea for the defendant of not guilty to all counts of the indictment. Mr. Furundzija was subsequently found to be indigent and assigned Mr. Luka Misetic, a practicing attorney in Chicago, Illinois, as defense counsel with fees paid by The International Tribunal.

Eleven studies involved patients with one or two specific types of traumatic event , six studies involved patients with different traumatic events , and one study did not specify .
Among 18 reports, eight studies used two control groups. One study compared PTSD patients to patients with current major depression, as well as TE participants. Another study compared PTSD to HC and patients suffering from depression/anxiety. Six other studies compared PTSD patients with TE and HC.
Ten studies used one control group: four studies only compared PTSD patients with TE and six studies only compared PTSD patients with HC.
All 18 reports were published between 1991 and 2017.
What Are The Symptoms Of Dissociative Amnesia
There are three types, or patterns, of dissociative amnesia:
- Localized: Memory loss affects specific areas of knowledge or parts of a persons life, such as a certain period during childhood, or anything about a friend or coworker. Often the memory loss focuses on a specific trauma. For example, a crime victim may have no memory of being robbed at gunpoint, but can recall details from the rest of that day.
- Generalized: Memory loss affects major parts of a persons life and/or identity, such as a being unable to recognize your name, job, family and friends.
- Fugue: With dissociative fugue, the person has generalized amnesia and adopts a new identity. For example, one middle manager was passed over for promotion. He did not come home from work and was reported as missing by his family. He was found a week later, 600 miles away, living under a different name, working as a short-order cook. When found by the police, he could not recognize any family member, friend or coworker, and he could not say who he was or explain his lack of identification.
Dissociative amnesia is different from amnesia caused by medical problems, such as illnesses, strokes or brain injuries. In medically caused amnesia, recovering memories are rare and generally a slow and gradual process.
Most cases of dissociative amnesia are relatively short. Often, memories return suddenly and completely. Memory recovery may be triggered by something in the persons surroundings, or in therapy.

Trauma & Memory Loss: The Amygdala
Your amygdala regulates fear and fear-based memories.
For example, a child who touches a hot stove stores that memory in their amygdala.
It teaches them that a behavior is dangerous by remembering the pain it caused.
This memory becomes imprinted by the rush of adrenaline produced by the traumatic event of pain.
The amygdala stores the emotion of the event and can be triggered into reproducing it in subsequent traumatic events.
A damaged amygdala can lead to difficulty regulating emotions or to feeling that the trauma is still happening.
When trauma occurs, the amygdala becomes hyperactive.
It becomes more sensitive to stimuli and often places the person into a constant fright response.
The effects of a traumatized amygdala are chronic stress, increased fear response, loss of sleep, and an inability to calm down.

Cognitive Risk And Protective Factors In Ptsd
PTSD is a unique psychiatric disorder in that it is the result of a traumatic life event. As such, it would be assumed that all neuropsychological and neurobiological abnormalities associated with PTSD are also caused by that event. However, prospective and twin studies offer compelling support, for the model that, pre-existing memory and learning deficits, and related hippocampal dysfunction, increase one’s vulnerability to developing PTSD. Gibertson et al75 studied monozygotic twin pairs who were discordant for combat exposure and found that the identical co-twins of combat veterans with PTSD, who had not, experienced combat exposure or PTSD themselves, showed similar deficits in verbal memory. In addition, both combat, veterans with PTSD and their co-twins exhibited smaller hippocampi,76 suggesting that a smaller hippocampus and memory impairments in PTSD represent a pre-existing, genetic factor. Further support for this framework has come from a recent longitudinal study, where researchers examined the extent, to which poorer neurocognitive functioning prior to a major natural disaster predicted the development, of PTSD symptoms.77 Development of PTSD symptoms was inversely associated with word recall, as well as working memory, processing speed, and verbal intelligence performance assessed pretrauma.
Work On Your Mindfulness
PTSD symptoms can be very distracting. You may find that you spend so much time focused on your fear, anger, or shame, for instance, that it affects your memory. One way to overcome this is to become more mindful.
Mindfulness involves being in the here and now. It requires letting go of the past, not worrying about the future, and being totally present in what is happening this moment. Ultimately, this removes your mental distractions.
You can improve your ability to stay in the present by practicing mindfulness meditation. Spend a few minutes each day sitting in a quiet, comfortable place and pay attention to your body as you breathe in and out. Try to clear your mind of all thoughts. When your mind wanders , just put those thoughts aside and bring your attention back to your breath.
Mindfulness meditation not only increases self-awareness and attention control, but it also helps you better regulate your emotions. So, it offers many benefits beyond those related to PTSD and memory loss.

Other Effects Of Ptsd
If you are experiencing symptoms of PTSD, you might also find that you have difficulty with some everyday aspects of your life, such as:
- looking after yourself
- remembering things and making decisions
- your sex drive
- coping with change
- simply enjoying your leisure time.
If you drive you may have to tell the DVLA that you have PTSD. For more information on your right to drive, including when and how to contact the DVLA, see our legal pages on fitness to drive.

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.

What Is The Difference Between An Er And A Trauma Center
A trauma center is equipped to handle the most serious of conditions such as car accident injuries, gunshot wounds, traumatic brain injuries, stab wounds, serious falls, and blunt trauma. While the ER treats a wider range of ailments ranging from non-life threatening injuries to potential heart attacks and strokes, a trauma center is equipped to handle the most serious of conditions such as car accident injuries, gunshot wounds, traumatic brain injuries, stab wounds, serious falls, and blunt trauma.
Memory Distortion Can Worsen Trauma Stress
Some people who experience trauma may remember the event happening, but not all of the details, such as the time or location where it took place.
The Mayo Clinic explains that this can happen because the traumatic event is recorded and embedded in their memory. However, the specific details or central facts may not be encoded in the persons memory, so it will be challenging to retrieve that information years later after the trauma has passed.
While some people may not be able to recall everything that happened, others may end up remembering things that didnt actually happen or did not happen the way they think they did. This is called memory distortion, or over-remembering trauma, and it can affect ones recollection of distressing experiences.
Psychology Today writer Nathan H. Lents, Ph.D., and Deryn Strange, professor of forensic psychology, explain this, writing, In fact, traumatic memory distortion appears to follow a particular pattern: people tend to remember experiencing even more trauma than they actually did. This usually translates into greater severity of Post-traumatic Stress Disorder symptoms over time, as the remembered trauma grows.
Adding on to the memory of a traumatic experience can harm ones mental health. The authors write that over-remembering has been linked to an increase in PTSD symptoms.
