[Stroke and intracranial hemorrhage after cocaine abuse].

Cocaine abuse as a risk factor for acute cerebrovascular events has received too little attention, in particular in young patients. Cocaine hydrochloride causes mainly intracerebral and subarachnoidal bleeding, while crack (freebase) causes intracranial hemorrhage and ischemic infarctions with equal frequency. Although no specific antidote is known, an attempt should be made to detect the substance or its metabolites in the urine so as to provide optimal management, and encourage the patient to seek expert counselling.
