Summary: | BackgroundPrenatal alcohol exposure (PAE) impacts cognition in childhood and early adulthood. Here we evaluate the cognitive abilities of middle‐aged adults with and without a history of PAE.MethodsParticipants (N = 200) were recruited from longitudinal cohorts in the Atlanta and Seattle metropolitan areas and completed measures comprising the National Institutes of Health Toolbox's Fluid Cognition Composite.ResultsWe found that individuals with PAE had lower Fluid Cognition Summary scores and lower Dimensional Change Card Sort and Flanker task subtest scores than non‐PAE controls, after accounting for both potentially confounding demographic variables using propensity scores and the effects of study site. When we evaluated the effects of PAE with and without dysmorphic physical features, we found that middle‐aged adults in both groups had lower fluid cognition scores than non‐PAE controls. However, only the presence of PAE with dysmorphic features was associated with lower performance on the Dimensional Change Card Sort Test and Flanker tasks.ConclusionWhile all participants with PAE had lower fluid cognition, those with PAE and dysmorphic features also exhibited specific deficits in their performance on measures of inhibition, attention, and cognitive flexibility. Thus, PAE is associated with ongoing cognitive deficits in middle adulthood, which can be observed most clearly among individuals with dysmorphic features. |
