Alcohol-related seizures

Alcohol-related seizures are defined as adult-onset seizures that occur in the setting of chronic alcohol dependence. Alcohol withdrawal is the cause of seizures in a subgroup of these patients; however, concurrent risk factors including pre-existing epilepsy, structural brain lesions, and the use of illicit drugs contribute to the development of seizures in many patients. New onset or a new pattern of alcohol-related seizures, e.g., focal seizures or status epilepticus, should prompt a thorough diagnostic evaluation. This is not indicated if patients have previously completed a comprehensive evaluation and the pattern of current seizures is consistent with past events. Treatment is initially directed at aggressively terminating current seizure activity. This should be followed by prevention of recurrent alcohol-related seizures and progression to status epilepticus during the ensuing 6-h high-risk period. Our purpose is to present recommendations for the diagnostic evaluation, treatment and disposition of these patients based on the current literature. (C) 2006 Elsevier Inc.
