Treatment consists of reversing the thiamine deficiency by giving supplemental thiamine, usually by starting with an initial intravenous or intramuscular dose followed by supplemental oral doses. It is important to start the thiamine treatment before giving any glucose as the encephalopathy will be worsened by the glucose. (Glucose administration promotes dehydrogenation of pyruvate, a biochemical reaction which consumes thiamine.)  By the time amnesia and psychosis have occurred, complete recovery is unlikely.
