Intelligence after stroke in childhood: a review of the literature and suggestions for future research
Review of published clinical and neuropsychologic outcome studies reveals limited information about intellectual functioning after childhood stroke. The extant data are supplemented here by analysis of intelligence quotient (IQ) results obtained from 38 children in an ongoing study of unilateral middle cerebral artery ischemic stroke. Evidence so far indicates that, after stroke, mean IQ falls significantly below the population mean but remains within the average range. There is no significant difference between hemispheric side of injury; the Verbal and Performance IQ lateralization profile widely recognized in adults with unilateral injury is not apparent in younger children, and there is only a trend toward this profile in older children. The effects of a number of other variables, including sex, site of stroke, and longitudinal assessment, are also considered. Although the generally minor effect of stroke on IQ is encouraging, a number of children do require extra help on return to school. Some suggestions for future research are highlighted in order to encourage further consideration of the issues raised here.

Abstract
Review of published clinical and neuropsychologic outcome studies reveals limited information about intellectual functioning after childhood stroke. The extant data are supplemented here by analysis of intelligence quotient (IQ) results obtained from 38 children in an ongoing study of unilateral middle cerebral artery ischemic stroke. Evidence so far indicates that, after stroke, mean IQ falls significantly below the population mean but remains within the average range. There is no significant difference between hemispheric side of injury; the Verbal and Performance IQ lateralization profile widely recognized in adults with unilateral injury is not apparent in younger children, and there is only a trend toward this profile in older children. The effects of a number of other variables, including sex, site of stroke, and longitudinal assessment, are also considered. Although the generally minor effect of stroke on IQ is encouraging, a number of children do require extra help on return to school. Some suggestions for future research are highlighted in order to encourage further consideration of the issues raised here.
