The major vitamin deficiency in Wernicke’s encephalopathy is :
Correct Answer: B1
Description: Wernicke's disease is a common and preventable disorder due to a deficiency of thiamine. Alcoholics account for most cases, but patients with malnutrition due to hyperemesis, starvation, renal dialysis, cancer, AIDS, or rarely gastric surgery are also at risk. The characteristic clinical triad is that of ophthalmoplegia, ataxia, and global confusion. However, only one-third of patients with acute Wernicke's disease present with the classic clinical triad. Most patients are profoundly disoriented, indifferent, and inattentive, although rarely they have an agitated delirium related to ethanol withdrawal. Ref: Hemphill, III J.C., Gress D.R. (2012).
