The syndrome can develop from unrecognized or undertreated Wernicke encephalopathy. The intra-individual course of Wernicke-Korsakoff syndrome has not been studied extensively, nor has the temporal progression of gait disturbances and other symptoms of Wernicke encephalopathy. Here we present the detailed history of a patient whose acute symptoms of Wernicke encephalopathy were far from stable. We follow his mobility changes and the shifts in his mental status from global confusion and impaired consciousness to more selective cognitive deficits. His Wernicke encephalopathy was missed and left untreated, being labeled as “probable” Korsakoff syndrome. Patients with a history of self-neglect and alcohol abuse, at risk of or suffering with Wernicke encephalopathy, should receive immediate and adequate vitamin replacement. Self-neglecting alcoholics who are bedridden may have severe illness and probably active Wernicke encephalopathy. In these patients, mobility changes, delirium, or impaired consciousness can be an expression of Wernicke encephalopathy, and should be treated to prevent further damage from the neurologic complications of thiamine deficiency. © 2014 by Lippincott Williams & Wilkins.
