Delirium
Confusion and delirium are serious issues that may occur in people who have a severe thiamine deficiency. Delirium is particularly common in older individuals who have nutritional deficiencies, and it may also occur in those who are thiamine-deficient due to alcohol abuse.
Delirium makes it hard for people to think clearly, and some people may experience hallucinations. Delirium is a dangerous symptom that requires immediate intervention from a medical professional.
