Anaesthesia => Amnesia


Amnesia, loss or impairment of memory. It may be caused by organic disorders, such as brain injury or cerebral arteriosclerosis, or by functional nervous disorders, such as hysteria. Amnesia may be total, with complete loss of recall; or partial, occurring only immediately before or after a traumatic event; or systematic, relating to a particular type or group of experiences. Amnesia is a symptom rather than a disease, and treatment attempts to determine and remove the basic cause.
