Wernicke's encephalopathy and Korsakoff's psychosis in alcoholics are thought to be due to thiamine deficiency. When the process goes untreated, patients may develop alcohol-induced persisting dementia. We review the literature on thermal dysregulation and the place of thiamine treatment in Wernicke's encephalopathy, Korsakoff's psychosis, and alcohol-induced persisting dementia. We describe a patient with alcohol-induced persisting dementia who showed thermal dysregulation which responded to parenteral but not oral thiamine. Subsequently, he developed aspiration pneumonia with associated fever reaction and expired. We describe the neuroimaging findings—diffuse cortical atrophy, ventricular dilatation, atrophy of the corpus callosum, hypothalamus, and medulla, and a probable arachnoid cyst in the left temporal tip. We conclude that thermal dysregulation was likely related to dysfunction of temperature regulatory brain centers, that thermal dysregulation was stabilized with parenteral but not oral thiamine, and that parenteral thiamine may have a role even in chronic cases of alcohol-induced persisting dementia.
