Epidemiology of young strokes in rural Kashmir, India

Stroke in young adults and children

Data from studies of 337 children and 1606 young adults are summarized to identify the major causes of stroke in these age groups. In children under 15 years of age, stroke occurs in patients with congenital heart disease, nonatherosclerotic vasculopathies, infection, and hematologic defects like sickle cell disease. In patients 15 to 35 years of age, dissection, cardioembolism, nonatheroslerotic vasculopathies, and prothrombotic states cause a significant percentage of strokes. In adults over 35 years of age, traditional atherosclerotic risk factors predominate. Lifestyle choices (e.g., cigarette smoking, alcohol consumption, and illicit drug use) can significantly increase the rate of stroke among young adults in a community. Limited access to healthcare may increase the role of infectious disease and peripartum complications.

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.
