Wernicke's Encephalopathy may progress to Korsakoff syndrome. Which option lists Korsakoff syndrome?

Wernicke's Encephalopathy may progress to Korsakoff syndrome. Which option lists Korsakoff syndrome?

• A. Huntington disease
• B. Korsakoff syndrome
• C. Parkinson disease
• D. Guillain-Barré syndrome

Answer: (B)

Korsakoff syndrome is the chronic amnestic sequel of Wernicke's encephalopathy caused by prolonged thiamine deficiency. It presents with profound anterograde amnesia, confabulation, and difficulty forming new memories, often with relatively preserved other cognitive functions early on. The question is asking for the term that names this progression, so the correct choice is Korsakoff syndrome. The other listed conditions—Huntington disease, Parkinson disease, and Guillain-Barré syndrome—are distinct disorders with different causes and presentations and do not represent this progression.
