Attention deficit hyperactivity disorder in school-aged children. Test performance in cognitive and neuropsychological measures

Abstract

The study presented examines cognitive and neuropsychological processes underlying behavioural symptoms of attention deficit hyperactivity disorder (ADHD). Information about the diagnostic process of ADHD is provided by corresponding study results. In English- speaking countries measures based on PASS processes are applied to assess the cognitive and executive deficits specific to ADHD. By considering several dynamic cognitive processes the PASS theory has been shown to be sensitive to the specific cognitive problems and executive deficits of children with ADHD. The role of a current measure based on the PASS theory, the Kaufman-Computerized Assessment Battery for Children (K-CAB), is discussed regarding the diagnostic process. This neuropsychological test battery is able to detect global deficits such as reduced reaction time or unexpected variability in reaction time. Inferences about specific cognitive abilities or behaviour patterns based solely on test results cannot be made.
