Kor·sa·koff syn·drome

(kōr-să'kof),
an alcohol amnestic syndrome characterized by confusion and severe impairment of memory, especially for recent events, for which the patient compensates by confabulation. Typically encountered in patients with long-term alcoholism, delirium tremens may precede the syndrome, and Wernicke syndrome often coexists with it. The precise pathogenesis is uncertain, but direct toxic effects of alcohol are probably less important than severe nutritional deficiencies often associated with chronic alcoholism.

dysmnesic syndrome

[disnē′sik]
a memory disorder characterized by an inability to learn simple new skills, although the person can still perform highly complex skills learned before the onset of the condition. The cause is a disease or injury that affects only certain brain tissues associated with memory. The victim often confabulates about events of the recent past for which there is no clear memory. Also called dysmnesia.
