Physical trauma such as a head injury or stroke can damage the brain and impair a person's 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.
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. A person with dissociative amnesia may have experienced the trauma or witnessed it.
Physical, emotional, and psychological trauma can all play a factor with memory loss. You can experience permanent or temporary memory loss depending on the type of trauma.
Trauma can shutdown episodic memory and fragment the sequence of events. The hippocampus is responsible for creating and recalling episodic memory. Trauma can prevent information (like words, images, sounds, etc.) from differ- ent parts of the brain from combining to make a semantic memory.
Healing from trauma is possible. And that includes possible symptoms of it, such as memory loss. Amnesia from traumatic experiences can be better addressed with the support of a mental health professional.
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.
Intrusive memories
Recurrent, unwanted distressing memories of the traumatic event. Reliving the traumatic event as if it were happening again (flashbacks) Upsetting dreams or nightmares about the traumatic event. Severe emotional distress or physical reactions to something that reminds you of the traumatic event.
These traumas can impact your brain's ability to form memories. It could be due to a physical impact on your brain, which impairs your ability to create memories. It also could be from your brain's attempt to cope with the emotional and psychological impact of the trauma. Sometimes you can develop dissociative amnesia.
PTSD related memory loss can make it difficult to remember lists or facts, can make memory seem fragmented or disorganized, or can lead to large gaps in memory altogether. These issues can have a serious impact on daily functioning, and one might not realize that these problems are related to PTSD.
The good news is that it's completely normal not to remember much of your early years. It's known as infantile amnesia. This means that even though kids' brains are like little sponges, soaking in all that info and experience, you might take relatively few memories of it into adulthood.
Suffering from chronic or ongoing depression. Practicing avoidance of people, places, or things that may be related to the traumatic event; this also can include an avoidance of unpleasant emotions. Flashbacks, nightmares, and body memories regarding the traumatic event.
Childhood trauma in adults also results in feeling disconnected, and being unable to relate to others. Studies have shown that adults that experience childhood trauma were more likely to struggle with controlling emotions, and had heightened anxiety, depression, and anger.
Signs and Symptoms
Strong reactions: Strong reactions can often catch you off guard. You might feel unsafe around a person you just met because the person reminds you of someone involved in your childhood trauma. Anxiety: Childhood trauma increases the risk of anxiety.
Smiling when discussing trauma is a way to minimize the traumatic experience. It communicates the notion that what happened “wasn't so bad.” This is a common strategy that trauma survivors use in an attempt to maintain a connection to caretakers who were their perpetrators.
Psychological, physical, or sexual abuse. Community or school violence. Witnessing or experiencing domestic violence. National disasters or terrorism.
Feeling jittery, nervous or tense.
Women experiencing PTSD are more likely to exhibit the following symptoms: Become easily startled. Have more trouble feeling emotions, experience numbness. Avoid trauma reminders.
Re-experiencing is the most typical symptom of PTSD. This is when a person involuntarily and vividly relives the traumatic event in the form of: flashbacks. nightmares.
People with PTSD have intense, disturbing thoughts and feelings related to their experience that last long after the traumatic event has ended. They may relive the event through flashbacks or nightmares; they may feel sadness, fear or anger; and they may feel detached or estranged from other people.
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.
Your brain is equipped with an alarm system that normally helps ensure your survival. With PTSD, this system becomes overly sensitive and triggers easily. In turn, the parts of your brain responsible for thinking and memory stop functioning properly.
There are absolutely health impacts from unresolved trauma. Unresolved trauma puts people at increased risk for mental health diagnoses, which run the gamut of anxiety, depression and PTSD. There are physical manifestations as well, such as cardiovascular problems like high blood pressure, stroke or heart attacks.
