Delirium or acute confusional state among hospitalized patients is a frequent and serious problem. It is characterized by acute onset symptoms, fluctuating course, impaired attention, unorganized thinking, and altered level of conciousness. Delirium, as a manifestation of acute nicotine withdrawal syndrome has been reported in the reviewed literature only in eight cases. We report the case of a heavy smoker admitted because of a reagudization of his chronic obstructive pulmonary disease. At the third day of nicotine abstinence, he developed delirium with a rapid improvement of his symptoms after treatment with a transdermal nicotine patch. This description suggests that in hospitalized heavy smokers who develop delirium with agitation, a simple trial with a nicotine patch can offer a dramatic therapeutic response in a few hours, constituing additionally a confirmatory test. The recognition of delirium as a manifestation of nicotine withdrawal could allow to determine the origin of symptoms and to apply the appropriate therapy, in certain complex cases that now remain undiagnosed.
