RESUMEN

Forty-one boys diagnosed with Duchenne muscular dystrophy (DMD) were each compared to an unaffected sibling on a battery of neuropsychological tests. Verbal. visuospatial, attention/memory, abstract thinking, and academic achievement skills were tested. Results indicated the boys with DMD performed similarly to their siblings on the majority of measures, indicating intact verbal, visuospatial, long-term memory, and abstract skills. However, the DMD group did significantly more poorly than their siblings on specific measures of story recall, digit span, and auditory comprehension, as well as in all areas of academic achievement (reading, writing, and math). This profile indicates that verbal working memory skills are selectively impaired in DMD, and that that likely contributes to limited academic achievement. The association between the known impact of the genetic mutation on the development of the central nervous system and boys' cognitive profile is discussed.

RESUMEN

OBJECTIVE: To determine whether all boys with Duchenne muscular dystrophy (DMD) have a similar verbal and memory profile of skills, or whether only a subset is affected, and to determine whether the weak areas in their profile are substantially different from a control group. METHODS: Performance of patients with DMD on neuropsychological tests of verbal and memory skills was examined in two ways. Standardized test scores for 80 boys with DMD (estimated IQ range, 70 to 160) were ranked individually from worst to best, and the individual rankings were compared across the group using Friedman rank analysis. Additionally, performance of 41 boys with DMD was compared with that of their sibling control subjects of similar age and estimated IQ using multivariate analysis of variance. RESULTS: Individual cognitive profiles were significantly similar among the subjects with DMD, such that for most subjects digit span, story recall, and comprehension were the tests on which each performed most poorly. This finding remained true regardless of whether they were of high or low intellectual function. In contrast, no significant cognitive profile was found among their sibling control subjects, and when compared with their siblings, the DMD group scored significantly more poorly on digit span, comprehension, and story recall, but not on other verbal and memory measures. CONCLUSIONS: Boys with DMD have a specific cognitive profile, regardless of their general level of cognitive function. Specifically, boys with DMD performed more poorly on tests requiring attention to complex verbal information than they did on other verbal or memory measures. The possibility that the missing dystrophin brain products may contribute to selective cognitive processing is considered.

RESUMEN

OBJECTIVE: To assess intellect and adaptive behavior in children with hypoplastic left heart syndrome (HLHS) who had undergone at least two surgical stages of the Norwood procedure. METHODS: Fourteen children with HLHS >3 years of age participated in the study. The patients underwent intelligence quotient (IQ) testing, and their parents were interviewed regarding their children's adaptive behavior. Results were compared with those of 10 family controls. Outcomes were studied for possible correlation with perioperative variables. RESULTS: Among the HLHS patients, the median scores for full scale IQ and adaptive behavior were 88 and 91, respectively (normal = 100 +/- 15). One child met criteria for mental retardation. Family controls scored generally higher than did HLHS patients, but only differences in adaptive behavior were statistically significant. A negative correlation was found between stage I circulatory arrest time and full scale IQ. CONCLUSIONS: Children with HLHS most often function in the low-normal range of intelligence and adaptive behavior. A prolonged circulatory arrest time may result in decreased intellectual function.
