Abstract
Three individual studies were done to assess the effectiveness of neurofeedback
treatment for Attention Deficit Hyperactivity Disorder (ADHD). The subject
pool for these studies 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
presentations were contingent on the production of 16-20 hz. (beta) activity
in the absence of 4-8 hz. (theta) activity. Changes in EEG activity, Test
of Variables of Attention (T.O.V.A.) performance, Attention Deficit Disorder
Evaluation Scale (ADDES) behavior ratings, and WISC-R performance following
neurofeedback training were assessed. Our results were as follows: Study
I indicated that subjects who successfully decreased theta activity showed
significant improvement in T.O.V.A. performance; Study II revealed significant
improvement in parent ratings following neurofeedback training; and Study
III indicated significant increases in WISC-R scores following neurofeedback
training. These studies are important in that they examine the effects
of neurofeedback training on both objective and subjective measures of
Attention Deficit Disorder under relatively controlled conditions. The
results support and extend previous published findings, indicating that
neurofeedback training is an appropriate and efficacious adjunctive treatment
for ADHD.

INTRODUCTION This presentation will consist of two parts. The first portion will provide both the scientific basis and a model for understanding neocortical dynamics and the EEG. The second portion will show how EEG biofeedback and related methodologies that modify the EEG and behavior can be explained by neocortical dynamics. |
