Neurological disorder marked by severe amnesia despite clear perception and full consciousness, resulting from chronic alcoholism, head injury, brain illness, or thiamin deficiency. Persons with the syndrome typically cannot remember events in the recent or even immediate past; some retain memories only a few seconds. Longer periodsup to 20 yearsmay also be forgotten. Confabulation (recounting detailed, convincing memories of events that never happened) sometimes coexists with the syndrome, which may be transient or chronic.
