A case series of young stroke in Rome

In this hospital case series study we enrolled 394 consecutive ischemic stroke patients aged 14-47 years, all of whom were submitted to a diagnostic protocol. We evaluated the incidence of cerebral ischemia in young adults, as well as the risk factors and the etiopathogenesis of this pathology. Modified diagnostic criteria adopted from the TOAST and Baltimore-Washington Cooperative Young Stroke Study were used for the etiologic classification. The crude annual incidence rate was 8.8/100 000 (95% CI 7.7-9.9), which is in keeping with the rates reported in comparable registries. Risk factors were distributed as follows: smoking in 56% of patients, hypertension in 23%, dyslipidemia in 15%, migraine in 26%, and diabetes mellitus in 2%. Oral contraceptives were being taken by 38% of the women enrolled. The etiology of stroke in the patients was as follows: cardioembolism in 34%, atherothrombosis in 12%, non-atherosclerotic vasculopathies in 14% (including arterial dissection in 12%), other determined causes in 13%, lacunar stroke in 2.5%, migraine in 1%, and undetermined causes in 24%. Despite its biased sampling frame, this large hospital case series, in which risk factor distribution and etiopathogenesis were investigated, stresses the need for an adequate diagnostic approach in young ischemic patients.
