Stroke: Improving characterization of childhood cerebral arteriopathies.

There is notable variation in incidence, presentation, risk factors, and prognosis for strokes occurring in children. At present, there is no stroke classification system specifically tailored to the multiple risk factors and etiologies of pediatric stroke. The study by the international Pediatric Stroke Study investigators on predictors of cerebral arteriopathy in children with arterial ischemic stroke deserves special attention in planning secondary stroke prevention strategies in this population of patients.
