Stroke in children in Yaounde, Cameroon.

ABSTRACT

Thirty five children aged 5 months to 15 years suffering from stroke were studied from August 1984 to July 1990 from two hospitals in order to determine the incidence, the etiological factors and the short term outcome of the stroke. The average annual incidence was 1.85 per 1000 pediatric hospitalizations. There was a progressive rise in the number of cases from 1985, with a peak in 1990. Motor impairment of one half of the body was the commonest clinical feature seen in 97.1% of the cases. Other clinical signs were facial paralysis (62.9%) and aphasia (28.6%). The main etiological factors were homozygous sickle cell disease (31.4%), heart disease (17.1%), cerebral malaria (14.3%) and meningitis (14.3%). No causative factor was identified in 7 patients (20%). The mortality rate was low (2.9%) and all the children had neurological deficit after a mean hospital stay of 15 days. Laboratory investigations including lipid analysis, platelet count, and skull X-rays proved to be of no diagnostic value. However, computed tomography (CT) scan confirmed the diagnosis of ischemic stroke whenever it could be done.
