is a severe disruption of memory without deficits in intelligence,
attention, perception or judgment. It may occur following
damage to any of several brain structures which are critical
There are three major classes of amnesia:
amnesia, which is an impairment in storing new memories,
amnesia, which is a loss of old memories, and psychogenic
amnesia (or fugue state), which involves temporary loss
of identity. Anterograde and retrograde amnesia usually result
from brain injury or disease, while psychogenic amnesia is
a psychological condition that occurs in the absence of brain
injury. When the term "amnesia" is used alone, it usually
connotes a syndrome of anterograde amnesia (possibly including
some degree of retrograde amnesia).
Temporary amnesia can also follow use of
certain drugs. In these cases, the individual may experience
anterograde amnesia for events that occurred while under the
influence of the drug; events occurring after the drug has
worn off are remembered normally. Drugs which can cause temporary
amnesia include benzodiazepines (e.g. Valium and Mogadon)
and anticholinergics (e.g. scopolamine). Electroconvulsive
therapy can also cause amnesia for the period of treatment.
