title: Chronic, habitual cocaine abuse and kindling-induced epilepsy: a case report.
abstract: Kindling has been suggested as a possible mechanism for cocaine-induced seizures in chronic cocaine abusers, even though no convincing examples have been reported. We report a 37-year-old woman who initially experienced generalized tonic-clonic seizures (GTC) only immediately after "crack" use. She had a normal examination, negative family or past history for seizures, and normal cranial computed tomography and EEG. After she had abused cocaine almost daily for 2 years, her EEG demonstrated bitemporal slowing with independent spikes, and seizures were no longer temporally associated with acute cocaine use. Thereafter, despite complete abstinence from cocaine and treatment with phenytoin, she continued to experience four to six GTC a month. In light of the lack of other predisposing factors for epilepsy, this case may represent an example of cocaine-induced kindling in humans.
