You probably know of cases where people who have been through severe trauma tend to have cognitive problems, particularly involving related memories with the traumatic event. For example, an abused child may grow completely forgetting the cases of such abuse, or unconsciously modify their memories of it. The same can happen for those who have experienced war, have suffered a terrible accident, have witnessed a violent death or have suffered sexual abuse. Extreme trauma may have lasting effects on a person and have many symptoms associated with it, such as amnesia, nightmares and panic attacks.
Clinically, the condition known as posttraumatic stress disorder or PTSD. Is defined as an acute anxiety disorder and persistent, it is a reaction to the serious psychological trauma of the experience of serious physical danger or a threat to psychological integrity of a person (in cases of emotional abuse or rape, for example). PTSD is different from the more common cases of PTSD, as defined as having symptoms lasting more than six months while the second is usually temporary. Other terms used to identify in the past include posttraumatic stress syndrome (PTS), the traumatic neurosis war, and war neurosis to the affected veterans.
Even relatively normal amounts of stress have been linked to poor memory and cognitive function, so it can be s memory loss symptoms of PTSD as well? The answer is obvious, but the explanation is not as simple as saying the memories traumatic forgetting is only a survival mechanism. Importantly, the memory loss associated with PTSD is not limited to block past traumatic experiences, but also can affect short-term memory or the brain's ability to store and retrieve new memories.
Studies suggest that the psychological effects of traumatic stress may actually correspond to actual physical damage in the brain as a result of trauma. Particularly affected by stress is part of the brain called the hippocampus, which is responsible for organizing the memories and make associations. Thus, loss of memory can be a symptom of stress disorder. Fragmented memory and dissociative some signs of deterioration, and experiencing flashbacks or nightmares may be related to the symptoms.
Brain scans with magnetic resonance imaging (MRI) can illustrate the magnitude of physical damage incurred in connection with PTSD. A number of veterans Vietnam War proved to have an 8% reduction in size of right hippocampus, while other differences were observed in other sections of the brain.
Damage to the hippocampus may get in the way of making new memories and general cognitive function as well. Some of the latest research shows that among the functions of the hippocampus is the building of new nerve cells, also called neurons, which are responsible for the transmission of impulses in the brain. Stress, especially PTSD, can damage the function. Respectively, a decrease in the number of neurons depending on the results of poor memory. Among the many concerns about the implications of the research is that those who have experienced trauma, especially in childhood may be at a great disadvantage when about learning.
