Comparison of behaviors exhibited by 19 hyperactive and 17 nonhyperactive (learning disordered) children found differences between groups to be more often qualitative than quantitative. Hyperactive students demonstrated more talking, unsystematic search, and motor impersistence while nonhyperactive students demonstrated more upper extremity…

The sleep profiles of 13 children (ages 5-13) with attention deficit hyperactivity disorder (ADHD) who were treated with a fixed dose of methylphenidate for at least one month were compared with those of 16 healthy siblings. Significantly more children with ADHD demonstrated sleep disturbances and higher rates of sleep disorders. (Author/CR)

A study of 62 children (ages 7 to 12) with attention-deficit hyperactivity disorder (ADHD) and 62 controls found that behavioral variables established robust, statistically significant differences between groups. Children with ADHD also scored worse on 31 out of 61 neuropsychological variables, but obtained better scores on WISC-R Comprehension…

This study compared parent and teacher behavioral ratings for 77 children (ages 5-16) diagnosed as having attention deficit disorder with hyperactivity (ADD/H), attention deficit disorder without hyperactivity (ADD/WO), or learning disabilities (LD). ADD/WO and LD children were rated similarly on symptoms of withdrawal and impulsivity but differed…

A three-year study found that children with learning disabilities displayed a persistent pattern of maladaptive classroom behavior that distinguished them from average achievers and was associated with continued underachievement, especially for attention and conduct problem subtypes. The developmental relationship between learning disabilities,…
