Patients with alcoholism and patients with malnutrition are prone to thiamine and vitamin B-12 deficiency, which can cause delirium.


For alcohol withdrawal and in cases of Wernicke encephalopathy.

Cyanocobalamin (Physicians EZ Use B-12, Nascobal)

Vitamin B-12 deficiency can cause confusion or delirium in patients who are elderly. Deoxyadenosylcobalamin and hydroxocobalamin are active forms of vitamin B-12 in humans. Vitamin B-12 is synthesized by microbes but not by humans or plants. Vitamin B-12 deficiency may result from intrinsic factor deficiency (pernicious anemia), partial or total gastrectomy, or diseases of the distal ileum.
