Amnesia
Amnesia, the partial or complete loss of memory, most commonly is temporary and for only a short span of experience. There are both organic and psychological causes for amnesia. Some organic causes include inflammation of the brain, head injury, or stroke. This type of memory loss occurs suddenly and can last a long time. The person may be able to recall events in the distant past but not yesterday or today. If the amnesia is caused by alcohol abuse, it is a progressive disorder, and there are usually neurological problems like uncoordinated movements and loss of feeling in the fingers and toes. Once these problems occur, it may be too late to stop drinking. In contrast, psychologically-based amnesia is almost always temporary. This type of memory loss may be triggered by a traumatic event with which the mind can not deal. Usually, the memory slowly or suddenly comes back a few days later, though not all of the trauma may be recalled. Only rarely does a person lose the memory of larger portions of their life. It is important to seek medical care if the symptoms of amnesia occur.
