Ethаnоl hаs myriаd effects оn the central nervоus system. Wernicke's encephalopathy is a medical condition resulting from thiamin deficiency. It is most commonly observed in individuals who drink heavily but consume little food. Since the metabolism of alcohol requires this nutrient, the body's stores of thiamin can become depleted under these conditions. The signs and symptoms of Wernicke's encephalopathy are similar to acute alcohol intoxication: disorientation, confusion, indifference, inattentiveness, and incoordination/gait ataxia. The feature that distinguishes Wernicke's encephalopathy, however, is ophthalmoplegia, which reverses rapidly following intravenous infusion of thiamin. Patients with Wernicke's encephalopathy who remain untreated often develop permanently impaired past and new memory but preservation of long-term memory and other cognitive skills, a condition known as Korsakoff's syndrome. Beriberi is also a condition resulting from a deficiency of dietary thiamin. Acutely, patients experience high-output cardiac failure with vasodilation, edema, and cardiac enlargement with wet beriberi. Dry beriberi usually affects both peripheral and central nervous system. Symptoms resolve with thiamin infusion in half of patients. The symptoms of acute alcohol intoxication vary by the amount consumed. At low levels, alcohol causes relaxation and a slowing of fine motor function. As more is consumed, speech becomes slurred, eyesight becomes blurry, and balance becomes unstable. Once the blood alcohol level exceeds 0.20 g/dL, the anesthetic properties of alcohol become prominent; the individual is likely to lose consciousness. Patients with suspected WE require immediate parenteral administration of thiamine. A recommended regimen is 500 mg of thiamine IV infused over 30 minutes three times daily for two consecutive days and 250 mg IV or IM once daily for an additional five days, in combination with other B vitamins. Administration of glucose without thiamine can precipitate or worsen WE; thus, thiamine should be administered before glucose. Because gastrointestinal absorption of thiamine is erratic in alcoholic and malnourished patients, oral administration of thiamine is an unreliable initial treatment for WE. High-dose parenteral thiamine therapy is justified based on the failure of lower doses to produce clinical improvement in some patients with WE; however, there are no randomized studies to support a particular dosing regimen.
