Neuropsychologic consequences of Reye syndrome.

R L Brunner, D J O'Grady, J C Partin

    The Journal of Pediatrics
    |November 1, 1979
    PubMed
    Summary

    Reye syndrome can cause lasting, subtle brain function deficits in children, impacting cognitive abilities. Early disease severity correlates with the extent of neuropsychological impairment, even after recovery.

    Area of Science:

    • Neuroscience
    • Pediatrics
    • Psychology

    Background:

    • Reye syndrome is a serious condition affecting children, with potential long-term neurological consequences.
    • Assessing the full spectrum of Reye syndrome's impact on brain function requires detailed neuropsychological evaluation.

    Purpose of the Study:

    • To quantitatively assess long-term behavioral and neuropsychological outcomes in children following Reye syndrome recovery.
    • To identify correlations between Reye syndrome severity and the degree of lasting cognitive and functional deficits.

    Main Methods:

    • Neuropsychological testing, including intelligence, school achievement, visual-motor coordination, social maturity, and Halstead-Reitan Batteries, was administered to 40 children post-Reye syndrome.
    • Data were analyzed to correlate clinical factors (grade, consciousness duration, transfusions) with neuropsychological test results.

    Main Results:

    • A strong correlation was found between Reye syndrome severity (clinical grade, consciousness duration, exchange transfusions) and the degree of neuropsychological impairment.
    • Children with milder Reye syndrome exhibited normal brain function and fewer academic issues.
    • While some functions like language and perceptual-motor skills improved over time, subtle, lasting higher cognitive deficits were identified, correlating with neurological involvement.

    Conclusions:

    • Reye syndrome can result in persistent, often subtle, higher cognitive deficits not always evident clinically.
    • Neuropsychological assessment is crucial for evaluating the "quality of survival" after Reye syndrome.
    • These quantitative measures are essential for comparing the effectiveness of different Reye syndrome treatment strategies.
