The recovery is often gradual, the memory slowly reclaiming isolated events while others are still missing. In another form, only certain isolated events are lost to memory.Īmnesia victims usually have a good chance of recovery if there is no irreparable brain damage. When amnesia results from a single physical or psychologic incident, such as a concussion suffered in an accident or a severe emotional shock, the victim may forget only the incident itself the victim may be unable to recall events occurring before or after the incident or the order of events may be confused, with recent events imputed to the past and past events to recent times.
Rarely is the memory completely obliterated. The technical term for this is repression. Psychologic factors may also cause amnesia a shocking or unacceptable situation may be too painful to remember, and the situation is then retained only in the subconscious mind. Amnesia is usually the result of physical damage to areas of the brain from injury, disease, or alcoholism. While very frightening for the patient, transient global amnesia generally has an excellent prognosis for recovery. In severe attacks, a person is completely disoriented and may experience retrograde amnesia that extends back several years. Attacks can be as brief as 30-60 minutes or can last up to 24 hours. (A transient ischemic attack, sometimes called "a small stroke," occurs when a blockage in an artery temporarily blocks off blood supply to part of the brain.) A victim experiences sudden confusion and forgetfulness. Over time I began noticing more missing time and then my spouse told me about my other personality. I just assumed I was daydreaming and lost track of time. This type of amnesia has no consistently identifiable cause, but researchers have suggested that migraines or transient ischemic attacks may be the trigger. Answer (1 of 4): The first few times I experienced Disassociative Amnesia I had no idea I missed anything. In some ways, this form of amnesia is the opposite of anterograde amnesia: the victim can recall events that occurred after a trauma, but cannot remember previously familiar information or the events preceding the trauma. However, unlike Localized Amnesia, individuals experiencing selective amnesia will have some limited memories remaining from the given time period. Selective amnesia is in a sense, a component of localized amnesia in that the individual can recall some, but not all, of the details during a specific time. Recent experiences and short-term memory disappear, but victims can recall events prior to the trauma with clarity. This form of amnesia follows brain trauma and is characterized by the inability to remember new information.
