Which vitamin deficiency is linked to Wernicke encephalopathy?

• A. Thiamine
• B. Riboflavin
• C. Niacin
• D. Ascorbic Acid

Answer: (A)

Thiamine (vitamin B1) deficiency is linked to Wernicke encephalopathy. Thiamine is a crucial cofactor for enzymes that convert glucose into usable energy in the brain. Without it, brain cells can’t generate enough ATP, leading to energy failure in key areas such as the mammillary bodies and thalamus. This energy shortfall produces the distinctive neurologic signs of Wernicke: eye movement abnormalities, ataxia, and confusion. It commonly occurs in people with chronic alcohol use or malnutrition, and it’s a medical emergency because rapid treatment can prevent progression and long-term damage. Treating with thiamine promptly is important, ideally before giving glucose, to avoid worsening neurologic injury. Other vitamins listed are associated with different deficiency syndromes, not Wernicke encephalopathy.
