Moderate and Severe Retardation

Eight to Twelve Hertz Occipital EEG Training with Moderate and Severely Retarded Epileptic Individuals

Three retarded epileptic individuals, with a variety of seizure disorders, were provided with 8-12 Hz occipital EEG biofeedback training. While seizures were not totally eliminated in any of the subjects, the results of the study indicated that all subjects exhibited decreases in some aspect of their seizure activity. The inability of all of the subjects to increase 8-12 Hz activity may best be explained in terms of the differing degree of effectiveness of the feedback stimuli in terms of their functionality as reinforcers. The results of the study indicate that changes in procedures will be necessary in order to determine if 8-12 Hz occipital EEG training is effective in reducing epileptic seizures.
