Dissociative amnesia is one of a group of conditions called dissociative disorders. Dissociative disorders are mental illnesses that involve disruptions or breakdowns of memory, consciousness, awareness, identity, and/or perception. When one or more of these functions is disrupted, symptoms can result. These symptoms can interfere with
a person's general functioning, including social and work activities, and relationships. Dissociative amnesia occurs when a person blocks out certain information, usually associated with a stressful or traumatic event, leaving them unable to remember important personal information. With this disorder, the degree of memory loss goes beyond normal forgetfulness and includes gaps in memory for
long periods of time or of memories involving the traumatic event. Dissociative amnesia is not the same as simple amnesia, which involves a loss of information from memory, usually as the result of disease or injury to the brain. With dissociative amnesia, the memories still exist but are deeply buried within the person's mind and cannot be recalled. However, the memories might
resurface on their own or after being triggered by something in the person's surroundings. There is some debate among professionals as to when “buried” memories may not always be true, and some experts warn against about the risks of “recovering” false traumatic memories. Dissociative amnesia has been linked to overwhelming stress, which might be the result of traumatic events -- such as war, abuse, accidents, or disasters -- that the person has experienced or
witnessed. There also might be a genetic link to the development of dissociative disorders, including dissociative amnesia, because people with these disorders sometimes have close relatives who have had similar conditions. Dissociative amnesia is more common in women than in men. The frequency of dissociative amnesia tends to increase during stressful or traumatic periods, such as during wartime or
after a natural disaster. The primary symptom of dissociative amnesia is the sudden inability to remember past experiences or personal information. Some people with this disorder also might appear confused and suffer from depression and/or
anxiety, or psychiatri disorders. If symptoms of dissociative amnesia are present, the doctor will begin an evaluation by performing a complete medical history and
physical exam. Although there are no lab tests to specifically diagnose dissociative disorders, the doctor might use various diagnostic tests, such as as neuroimaging, electroencephalograms (EEGs), or blood tests, to rule out neurological or other illnesses or
medication side effects as the cause of the symptoms. Certain conditions, including brain diseases, head injuries, drug and alcohol intoxication, and
sleep deprivation, can lead to symptoms similar to those of dissociative disorders, including amnesia. If no physical illness is found, the person might be referred to a psychiatrist or psychologist, health care professionals who are specially trained to
diagnose and treat mental illnesses. Psychiatrists and psychologists use specially designed interview and assessment tools to evaluate a person for a dissociative disorder. How Is Dissociative Amnesia Treated?The first goal of treatment for dissociative amnesia is to relieve symptoms and control any problem behavior. Treatment then aims to help the person safely express and process painful memories, develop new coping and life skills, restore functioning, and improve relationships. The best treatment approach depends on the individual and the severity of their symptoms. Treatments may include the following:
The outlook for people with dissociative amnesia depends on several factors, including the person's
life situation, the availability of support systems, and the individual's response to treatment. For most people with dissociative amnesia, memory returns with time, making the overall outlook very good. Can Dissociative Amnesia Be Prevented?Although it may not be possible to prevent dissociative amnesia, it might be helpful to begin treatment in people as soon as they begin to have symptoms. Immediate intervention after a traumatic event or emotionally distressing experience can help to reduce the likelihood of dissociative disorders. What is psychological amnesia?Psychogenic amnesia refers to cases of memory loss presumed to have a psychological, rather than neurological, cause; and is either 'global' or situation-specific (Kopelman, 1987, 2002a). Global psychogenic amnesia is characterized by a sudden loss of autobiographical memories for the whole of a person's past.
