Abstract:
Thiamine deficiency (vitamin B1) is common in patients with alcohol dependence. Cognitive impairments may be an early consequence of thiamine deficiency. Wernicke's encephalopathy is underdiagnosed and undertreated. In patients with established Wernicke's encephalopathy, parenteral thiamine 200-500mg three times a day should be given for 3-5 days, followed by oral thiamine 250-1000mg/day. In patients with suspected Wernicke's encephalopathy, parenteral thiamine 250-300mg should be given two times a day for 3-5 days, followed by oral thiamine 250-300mg/day. In patients at high risk of thiamine deficiency, parenteral thiamine 250-500mg/day should be given for 3-5 days, followed by oral thiamine 250-300mg/day. In patients at low risk (with uncomplicated alcohol dependence), oral thiamine 250-500mg/day should be given for 3-5 days, followed by oral thiamine 100-250mg/day.
