Stroke in the young in Sicily: prevalence and clinical features.

Few epidemiological reports focus on the prevalence of stroke in the young population. As part of a neuroepidemiological survey on the total population of three Sicilian municipalities, we assessed the prevalence of stroke in the young, describing the clinical features of each patient. We screened 14,832 subjects younger than 40 years with a door-to-door method and a two-phase study design. Phase 1 consisted of a questionnaire and a brief neurological examination; phase 2 was an extensive evaluation performed by a neurologist. On the prevalence day (November 1, 1987), we ascertained six cases of stroke (prevalence rate, 40.5/100,000). Three were hemorrhagic, one ischemic, and two of uncertain type. Recovery was good in five patients; only one needed aids for walking. Stroke is uncommon in the young, but its prevalence rapidly increases in an age-related fashion. Hemorrhagic lesions are probably more represented in this age-group. Survivors tend to show good motor recovery.
