title: [Neurologic complications caused by use of cocaine, amphetamines and sympathomimetics].
abstract: Drug abuse has become a social and medical problem. Amphetamine and cocaine have a potent sympathicomimetic action, so they have important effects on the Central Nervous and Cardiovascular Systems. Their neurological complications are principally: psychic alterations, seizures and stroke (hemorrhagic and ischemic). The latter are the most important in the clinical practice. Their capacity to produce transit arterial hypertension and cerebral vascular constriction could be the physiopathological substrate of such alterations. Angiographic studies have shown lesions suggesting vasculopathy. In the last ten years cocaine abuse has become an authentic epidemic. We have reviewed its neurological complications, particularly the vascular ones--42 hemorrhagic and 24 ischemic--and the following conclusions were drawn: it should be considered as a risk factor in the younger age group; a short period of time between the last drug dose and the clinical picture is frequently seen; clinical features may appear with the first drug administration; no characteristic lesion in relation to the way of administration or consumption time was elicited.
