Outcome of stroke in Saudi children.
OBJECTIVE
To report on the prognosis, neurologic outcome, and recurrences of stroke in Saudi children.


METHODS
We evaluated a cohort of 104 Saudi children with stroke at the Division of Pediatric Neurology at King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, Saudi Arabia from July 1992 to February 2001 (retrospective study) and February 2001 to March 2003 (prospective study). We analyzed the salient clinical, neuroimaging, neurophysiological, neuropsychological and laboratory data following retrieval from a specialty designed comprehensive protocol.


RESULTS
Of the 104 children in the cohort (aged one month to 12 years), 5 (4.8%) died during the study period and 9 (8.7%) were lost to follow-up. The mean duration of follow-up for the remaining 90 children was 40 months (median 33 months). Recovery was judged complete in 6 (6.7%) of these 90 children. We detected residual hemiparesis (irrespective of its effect on daily functions) in 73 (81%) and this was combined with other motor deficits in 45 children (50%). Forty-one children (46%) had residual dysphasia or language deficits, whereas 45 (50%) were judged to have had cognitive deficit. Psychometry revealed an abnormal intelligence quotient test (<70) in 19 of 26 (73%) children. Other neurologic sequelae included epilepsy in 52 (58%), recurrent headaches in 13 (14%) and hydrocephalus in 4 (4.4%) patients. Six of the 95 (6.3%) children, who were ascertained to have died or kept their follow-up, had one or more recurrences, one month to 5 years after the initial stroke (median 23 months). Patients who had recurrent strokes were significantly more likely to be the product of consanguineous marriages (p=0.04). Regarding the group of 23 children with perinatal stroke, neither deaths nor recurrences occurred during the follow-up period. However, 20 (87%) of them had significant delays in their developmental milestones.


CONCLUSIONS
The toll of stroke in Saudi children is demanding, with most children demonstrating persistent neurologic or cognitive deficits. Primary prevention for recurrences is feasible through informed genetic counseling.
