amnestic syndrome a mental disorder characterized by impairment in short- and long-term memory, with anterograde and sometimes retrograde amnesia, occurring in a normal state of consciousness. Disorientation, confabulation, and a lack of insight into the memory deficit may be present. The most common cause is thiamine deficiency associated with chronic alcohol abuse (alcohol amnestic disorder, korsakoff's syndrome), but the syndrome may result from any pathologic process causing bilateral damage to certain structures in the medial temporal lobe and diencephalon, including head trauma, brain tumors, infarction, cerebral hypoxia, carbon monoxide poisoning, and herpes simplex encephalitis.
