A study with three component parts was performed to assess the effectiveness of neurofeedback treatment for Attention Deficit/Hyperactivity Disorder (ADHD). The subject pool consisted of 23 children and adolescents ranging in age from 8 to 19 years with a mean of 11.4 years who participated in a 2- to 3-month summer program of intensive neurofeedback training. Feedback was contingent on the production of 16-20 hertz (beta) activity in the absence of 4-8 hertz (theta) activity. Posttraining changes in EEG activity, T.O.V.A. performance, (ADDES) behavior ratings, and WISC-R performance were assessed. Part I indicated that subjects who successfully decreased theta activity showed significant improvement in T.O.V.A. performance; Part II revealed significant improvement in parent ratings following neurofeedback training; and Part III indicated significant increases in WISC-R scores following neurofeedback training. This study is significant in that it examines the effects of neurofeedback training on both objective and subjective measures under relatively controlled conditions. Our findings corroborate and extend previous research, indicating that neurofeedback training can be an appropriate and efficacious treatment for children with ADHD.

The objective of this study was to determine whether Ritalin (methylphenidate, MPH) affects cognitive flexibility and creativity in children with Attention Deficit Hyperactivity Disorder (ADHD). Measures administered included the Wisconsin Card Sorting Test-Revised (WCST-R), the Test of Divergent Thinking (TDT), and the Conners' ADHD rating scale, for both on and off MPH conditions. Comparison of on and off MPH data indicated that MPH administration significantly decreased symptoms of ADHD, as rated by parents on the Conners'. No significant differences were found on the WCST-R as a function of MPH administration. The Elaboration subscale of the TDT was the only scale to show a significant decrease in scores with MPH administration.
