Which chronic condition results from thiamine deficiency and is characterized by confusion, memory problems, and coordination issues?

• A. Wernicke-Korsakoff syndrome
• B. Wernicke encephalopathy
• C. Withdrawal
• D. Delirium

Answer: (A)

Thiamine deficiency damages brain areas essential for memory and coordination, and it can produce a spectrum called Wernicke-Korsakoff syndrome. The chronic form, Korsakoff syndrome, mainly presents with confusion and significant memory problems, often accompanied by coordination difficulties from underlying brain damage. The acute phase is Wernicke encephalopathy, which includes confusion plus eye movement problems and ataxia; if not treated, it can progress to Korsakoff syndrome. So the described chronic features point to Wernicke-Korsakoff syndrome. The other options refer to different conditions: Wernicke encephalopathy is the immediate, acute phase; withdrawal and delirium are distinct states not specifically defined by thiamine deficiency.
