Which symptom set is more characteristic of Wernicke encephalopathy than Korsakoff syndrome?

• A. Ataxia and ophthalmoplegia
• B. Severe anterograde amnesia
• C. Memory confabulation
• D. Auditory hallucinations

Answer: (A)

The key idea is recognizing how Wernicke encephalopathy presents differently from Korsakoff syndrome. Wernicke encephalopathy is an acute neurologic condition from thiamine deficiency and is known for signs that reflect brainstem and cerebellar involvement: gait ataxia and eye movement abnormalities such as ophthalmoplegia (or nystagmus), often with confusion or altered mental status. These motor and eye signs point to the acute, reversible phase affecting coordination and gaze control. Korsakoff syndrome, by contrast, is a chronic amnestic disorder that typically follows or accompanies Wernicke changes and is characterized mainly by severe anterograde amnesia and memory confabulation, with relatively less emphasis on eye or coordination problems early on. So memory problems are the hallmark of Korsakoff, whereas the combination of ataxia and eye movement abnormalities is classic for Wernicke. Auditory hallucinations aren’t typical distinguishing features of either condition and aren’t used to differentiate them. Prompt thiamine treatment is crucial to prevent progression from the acute WE phase to the chronic KS phase.
