Preliminary study of working memory in children with stroke related to sickle cell disease.
The verbal working memory abilities of children with stroke related to sickle cell disease (SCD) (n = 20) were compared to those of control children with SCD who had no history of stroke (n = 11). Memory span for one-, two-, and three-syllable words was assessed. For children with anterior infarcts, overall span was comparable to that of controls, but the typical effect of word length on span was reduced. For children with diffuse infarcts, overall span was reduced in comparison to that of controls, but the typical effect of word length on span was observed. For children with posterior infarcts, overall span was comparable to that of controls and the typical effect of word length on span was observed. These results provide preliminary evidence that patterns of working memory performance may vary across children with infarcts affecting different regions of the brain.
