Presentation of Acute Wernicke's Encephalopathy and Treatment with Thiamine

Thirty two cases of acute Wernicke's encephalopathy were observed in a period of 33 months, and prior to the mandatory thiamine enrichment of Australian bread-making flour in 1991. These cases were carefully assessed by multiple tests at specified intervals prior to, and following thiamine administration until discharge from hospital. Structured scoring of neurological signs and symptoms, CT scans, psychometry, nutritional measurements, and liver biopsies were performed. There was variation in the presentation and severity of clinical signs and symptoms and in response to treatment. All patients had alcohol-related liver disease, and the results indicated that fatty liver was important in presentation and in response to treatment with thiamine. Other forms of alcohol related brain damage were present in these patients, most of whom were in the 4th or 5th decade of life and had been drinking beer to excess for more than 20 years.
