Five cases of presumed nicotine withdrawal delirium among brain-injured patients treated in a neurologic intensive care unit are presented. Each patient had a history of heavy tobacco use and experienced dramatic and sustained clinical improvement within hours of transdermal nicotine replacement. These preliminary observations suggest that nicotine withdrawal may be an under-recognized cause of delirium in patients with acute brain injury.
