Which condition is the memory-related disorder characterized by an inability to recall recent events and learn new information, often linked to alcohol use?

• A. blackout
• B. Wernicke's disease
• C. Korsakoff's psychosis
• D. Alcoholic dementia

Answer: (C)

Korsakoff's psychosis is a memory-related disorder caused by chronic alcohol use leading to thiamine (vitamin B1) deficiency that damages brain areas involved in memory, especially the mammillary bodies and thalamus. The hallmark is severe difficulty forming new memories and recalling recent events, while some older memories may be relatively preserved. People often struggle to learn new information and may fill memory gaps with fabricated stories (confabulation) to make sense of gaps. This condition commonly follows an episode of Wernicke's encephalopathy if not treated, linking the memory impairment directly to alcohol-related brain injury. By contrast, a blackout refers to temporary memory loss for events during intoxication, Wernicke's disease is an acute neurologic syndrome with confusion and coordination problems, and alcoholic dementia is a broader label that doesn’t pinpoint the specific memory pattern described.
