Which condition is associated with Vitamin B1 deficiency and may be corrected nutritionally?

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

Answer: (C)

Vitamin B1 (thiamine) deficiency leads to acute brain problems that can be reversed with proper nutrition and thiamine supplementation. The condition that best fits this description is Wernicke's disease, which presents with sudden neurological symptoms like confusion, unsteady movement (ataxia), and eye movement abnormalities. Providing thiamine at once can reverse or lessen these symptoms and prevent progression to more permanent damage. It’s important to recognize that Korsakoff’s psychosis, while related, is usually a later, more chronic consequence that often includes lasting memory problems and is not fully reversible. Other terms like blackout or alcoholic dementia are less specific to the acute, treatable deficiency focus.
