The regional cerebral blood flow of 12 patients with severe alcohol
withdrawal reactions (delirium tremens or impending delirium tremens) was
measured during the acute state before treatment and after recovery.
Greater cerebral blood flow was significantly correlated with visual
hallucinations and agitation during the acute withdrawal reaction. The
results suggest that delirium tremens and related clinical states represent
a type of acute brain syndrome mainly characterized by CNS
hyperexcitability.
