By Michael Nielsen One day in the mids, a Moscow newspaper reporter named Solomon Shereshevsky entered the laboratory of the psychologist Alexander Luria. Shereshevsky's boss at the newspaper had noticed that Shereshevsky never needed to take any notes, but somehow still remembered all he was told, and had suggested he get his memory checked by an expert. Luria began testing Shereshevsky's memory. He began with simple tests, short strings of words and of numbers.
Types[ edit ] Anterograde amnesia is the inability to create new memories due to brain damage, while long-term memories from before the event remain intact. The brain damage can be caused by the effects of long-term alcoholism, severe malnutritionstrokehead traumaencephalitissurgery, Wernicke—Korsakoff syndromecerebrovascular eventsanoxia or other trauma.
Anterograde amnesia cannot be treated with pharmacological methods due to neuronal loss. Likewise, social and emotional support is critical to improving quality of life for anterograde amnesia sufferers.
One may be able to encode new memories after the incident. Retrograde is usually caused by head trauma or brain damage to parts of the brain besides the hippocampus. The hippocampus is responsible for encoding new memory.
Episodic memory is more likely to be affected than semantic memory.
The damage is usually caused by head trauma, cerebrovascular accident, stroke, tumorhypoxiaencephalitisor chronic alcoholism. People suffering from retrograde amnesia are more likely to remember general knowledge rather than specifics.
Recent memories are less likely to be recovered, but older memories will be easier to recall due to strengthening over time. The operation of this longer-term consolidation process is seen in the retrograde amnesia of patients with hippocampal damage who can recall memories from childhood relatively normally, but are impaired when recalling experiences that occurred just a few years prior to the time they became amnesic.
Traumatic amnesia is often transient, but may be permanent or either anterograde, retrograde, or mixed type. The extent of the period covered by the amnesia is related to the degree of injury and may give an indication of the prognosis for recovery of other functions.
The sufferer may also lose knowledge of who people are. Having longer periods of amnesia or consciousness after an injury may be an indication that recovery from remaining concussion symptoms will take much longer.
Dissociative amnesia can include: Repressed memory is the inability to recall information, usually about stressful or traumatic events in persons' lives, such as a violent attack or disaster.
The memory is stored in long-term memory, but access to it is impaired because of psychological defense mechanisms. Persons retain the capacity to learn new information and there may be some later partial or complete recovery of memory. Formerly known as "Psychogenic Amnesia".
Dissociative fugue formerly psychogenic fugue is also known as fugue state. It is caused by psychological trauma and is usually temporary and unresolved, and therefore may return.
An individual with dissociative fugue disorder is unaware or confused about his or her identity and will travel in journeys away from familiar surroundings to discover or create new identities. The episodes, called fugues, result from trauma or stress. Dissociative fugue often manifests as sudden, unexpected, purposeful travel away from home.
Posthypnotic amnesia occurs when events during hypnosis are forgotten, or where past memories are unable to be recalled.To arrive at the edge of the world's knowledge, seek out the most complex and sophisticated minds, put them in a room together, and have them ask each other the questions they are asking themselves.
