Neuropsychological Correlates of Cystic Fibrosis in Patients 5 to 8 Years Old

Abstract

Intellectual, academic, and neuropsychological tests were administered to 20 children with cystic fibrosis (CF). Results were compared to test results from 20 controls matched for gender, age, and socioeconomic status. No differences between the groups were found. For children with CF, Verbal IQ, sensory-perceptual skills, and incidental learning correlated (rs = .39-.67) with Shwachman criteria of disease severity, with significant positive relations with the Growth and Nutrition measure, an index of the severity of the disease. Processing of tactile-perceptual information may be particularly vulnerable to disease severity. This study provides more information than previously available on the neuropsychological status of young children with CF, and it offers some hypotheses regarding the relation between disease severity and neuropsychological function.
