Dissociative amnesia is loss of memory due to head trauma. People who suffer from dissociative amnesia struggle to recall crucial details about their past. This forgetfulness may be confined to a particular region or encompass a significant portion of the person's identity or life history.
Dissociative amnesia typically occurs after a traumatic experience and is not caused by obvious brain damage. It is believed to represent a reversible impairment in memory retrieval, most likely brought on by memory repression. However, it is unclear what brain mechanisms underlie this syndrome. Overwhelming stress, which can be brought on by traumatic events like war, abuse, accidents, or disasters, has been related to dissociative amnesia.
