Prevention and treatment of Wernicke-Korsakoff syndrome

Abstract

Wernicke's encephalopathy (WE) is both common and associated with high morbidity and mortality and yet there is evidence that appropriate and effective prophylaxis and treatment are often not given. Effective treatment and prophylaxis may only be achieved by use of parenteral vitamin supplements, since oral supplements are not absorbed in significant amounts. Although there are rare anaphylactoid reactions associated with the use of parenteral thiamine preparations, the risks and consequences of inadequate prophylaxis and treatment, in appropriately targeted groups of patients, are far greater. It is therefore proposed that all in-patient alcohol withdrawal should be covered by prophylactic use of parenteral thiamine, that there should be a low threshold for making a presumptive diagnosis of WE, and that there is a need for guidelines to assist physicians in appropriate management of this common clinical problem. © 2000 Medical Council on Alcoholism.
