Wernicke's syndrome is generally common in alcoholic persons, which is characterized by less mental activity and dual vision. It is caused by the deficiency of Riboflavin, Pyridoxine, Thiamine, or Retinol?

Vitamin-B, (thiamine) deficiency is most commonly observed in alcoholic persons. Prolonged deficiency of thiamine may lead to decreased mental function, double vision, reduced muscular contraction, and a lack of decision-making capability. These ill effects result in a disorder known as Wernicke's syndrome.
