Neurocognitive function profile in HIV-infected school-age children.

Objectives: Evaluation of neurocognitive function of school-age children with HIV.

Design: Cross-sectional observational study.

Methods: Twenty-two children (median age 9.

Inhibition of prepotent responding and attentional flexibility in treated phenylketonuria.

Inhibition of prepotent responding and attentional flexibility were assessed in 58 early and continuously treated phenylketonuria (PKU) patients and 69 controls, age 7 to 14 years. A computerized task was used requiring participants to process consecutive stimuli according to various attentional sets. Analysis of error rate suggested poorer inhibition of prepotent responding in PKU patients compared with controls.
