[The performances of attention deficit/hyperactivity disorder on neuropsychological tests of children].
The purpose of this study was to investigate the Attention Deficit/Hyperactivity Disorder (ADHD) by neuropsychological tests of children. There were two groups of subjects; one group was 23 ADHD children, the other group was 33 normal children. All of the subjects were 5 to 8 years old (mean = 7.05). The social economic status differences were nonsignificant between the two groups (chi-square = 0.52, p > 0.05). The instruments were WISC-R, Tests of Psycholinguistic Abilities, Diagnostic Arithmetic Test, and Reitan-Indiana Neuropsychological test for yound children. The findings were: (1) For all IQs (verbal, performance, full), the ADHD group was significantly lower than the normal group, and there were 8 (34.8%) ADHD children who were mental retards, 3 (13.0%) ADHD children were borderline mental retards, and there was just one (3.0%) normal child who was a borderline mental retard. (2) For academic abilities (Tests of Psycholinguistic Abilities, and Diagnostic Arithmetic Tests), the ADHD group was significantly (p < 0.05) lower than the normal group, and the higher the grade, the larger the difference. (3) For neuropsychological tests, if cut-off points of performance level (0, 1, 2, 3) were percentile 5, 10, and 25 for all of the subjects, then there 12 variable criteria were lower than the Reitan's, 3 variable criteria were higher than the Reitan's, 29 variable criteria were similar with Reitan's, and 8 variables were indiscriminate between individuals. (4) The motor functions and higher cognitive abilities of the ADHD group were worse than those of the normal group.
