• fetal alcohol spectrum disorder
• prenatal alcohol exposure
• neuropsychological assessment
• age-related differences
• childhood and adolescence.

This cross-sectional study examined 6 key areas of neuropsychological functioning (cognitive, academic, attention, executive function, adaptive skills) comparing adolescents and school-age children with prenatal alcohol exposure (PAE). The aims were: (i) to examine which neuropsychological measures were predictive of an FASD diagnosis in adolescents and school-age children with PAE, and (ii) to compare the neuropsychological performance of adolescents and children diagnosed with FASD. Hierarchical logistic regressions determined that the Full-Scale IQ, Verbal Comprehension and Perceptual Reasoning indices, basic reading and math skills, adaptive functioning at school, and components of executive functioning (dependent on age) improved the probability of an accurate FASD diagnosis in both groups: 9.1% to 19.2% for adolescents and 10.9% to 19.4% for school-age children (61.5%-80.9% correct classifications overall). For the age comparison analyses (ANOVAs/MANOVAs), a significant difference was observed in the cognitive domain, as well as with basic math skills (trend) in the sample diagnosed with FASD, with lower scores observed for adolescents across these measures. These findings provide further evidence for age differences in neuropsychological assessment as well as increased neuropsychological difficulties in adolescence by comparison with childhood with FASD. Longitudinal studies will be needed to make further inferences about developmental changes in neuropsychological functioning in FASD.
