Tested prefrontal and hippocampal functions in school-aged individuals with Down syndrome (DS) compared functions with those of typically developing children individually matched on mental age. Found that hippocampal and prefrontal composite scores contributed unique variance to the prediction of mental age and adaptive behavior. Noted a…
