Which combination constitutes the classic triad of Wernicke's encephalopathy?

• A. Ataxia, Seizures, Eye paralysis
• B. Confusion, Hypertension, Eye paralysis
• C. Deterioration of memory, disorientation, paresthesias
• D. Ataxia, Confusion, Eye paralysis

Answer: (D)

Wernicke's encephalopathy is defined by a triad of ocular motor dysfunction (eye paralysis/ophthalmoplegia), gait ataxia, and confusion. The combination of ataxia, confusion, and eye paralysis directly reflects these three hallmark features, making it the best match for the classic presentation. The other options mix in signs like seizures, hypertension, memory changes without the full triad, or sensory symptoms that aren’t part of this classic picture. In practice, any suspicion should prompt prompt thiamine administration to prevent progression.
