Rationale:

Efficacy of EEG Biofeedback training in Attention Deficit Hyperactivity Disorder (ADHD) on brain electrical activity was studied.

Methods:

Thirty sessions (45 minutes each) of EEG Biofeedback training were applied to 40 ADHD subjects aged 9-13 years. Two-channel Brainfeedback® equipment was used. Training protocols addressed ADHD symptoms (left hemisphere inattentiveness and right hemisphere hyperactivity). The EEG conditioning protocols rewarded EEG amplitudes in the 15-20 and 12-15 Hz frequency bands respectively, and inhibited theta (4-7 Hz) and fast beta (>20 Hz) bands. Independent EEG assessments were provided.

Results:

Clinical EEG evaluations before and after treatment were followed by quantitative EEG and multivariate mathematical analyses by Wave-Finder software. Pre-training EEG of subjects averaged moderate to heavy retarded EEG (an insufficient alpha presence, and a diffuse slow activity). Post-training signal decreased significantly in delta (1-3 Hz; p<0.001) and fast beta (>20 Hz; p<0.05) activity in the stimulated areas. Mathematical analyses confirmed significant changes in the increase of stability; lower amplitude and amplitude variance; the maximum occurrence of the alpha activity moved from central-parietal areas into parietal-occipital.

Conclusions:

The efficacy study has reached changes in EEG native signal following the training: post-training clinical evaluation found significant (p<O.001) shift in the group average to age-adequate maturation level. Overall brain electrical activity has matured and normalized in 85 per cent of the ADHD subjects.
