Classification of Amnesia

Introduction

Amnesia is a profound memory loss which is usually caused either by physical injury to the brain or by the ingestion of a toxic substance which affects the brain. In addition, the memory loss can be caused by a traumatic, emotional event. (Parkin, 1999)

They may be disoriented and confused. Their memory deficit causes problems for them either at work, in school, or in social settings. Sometimes the memory loss is severe enough to necessitate a supervised living situation may receive an injury.

With more specialized look indicates that memory is the potential that the central nervous system to define, organize, update and recognize our past mental events, closely associated with the function of attention. I would say that human memory can store more data, and is far more complex than any existing computer, although both systems store data in three similar stages: encoding, storage and recall. Poisoned by drugs (for example, chronic inhalation of organic solvents, amphotericin, alcohol, lithium, etc.) are another cause of brain degeneration. In medical parlance, the 'amnesia is a disorder of long-term memory episodic. It is generally found in a person where amnesia may be unable to recall events in his life recently or in severe cases even remote events, and may not be able to acquire permanent new memories, while it is generally preserved the ability to learn new actions. The more general overview of amnesia is provided below which contain the classification of the topic where as the habits attained due to the problem.

It is a progressive disorder, static or in remission, which affects short term memory and long term memory loss. There is loss of view, including mental functions.

Classification of Amnesia

Retrograde amnesia

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.

Transient global amnesia

A temporary loss of all memory, but it particularly affects the ability to form new memories (severe anterograde amnesia), with milder loss of past memories (retrograde amnesia) going back a few hours.

Traumatic amnesia

Traumatic amnesia is caused by brain damage from a hard blow to the head, such as in a car accident. It can lead to anything from a brief loss of consciousness to coma.

Wernike-Korsakoff's psychosis

Wernike-Korsakoff's psychosis is memory loss caused by extended alcohol abuse. This tends to be a progressive disorder and is usually accompanied by neurological problems, such as uncoordinated movements and loss of feeling in the fingers and toes. Memory impairment in the short and long term, and is of organic origin such as stroke, head trauma, hypoxia, herpes simplex encephalitis, hipotiaminosis and alcohol and not due to a confessional state or dementia.

Hysterical (fugue) amnesia

There are two or more personalities or personality states in the same individual, each with its own memory, worst may share memories, and one of the personalities can have the memory of all others, by giving ...
