The EEG biofeedback treatment of ADHD may be important in prevention for children and adolescents at risk for developing SUD. It may be possible that EEG biofeedback therapy of childhood ADHD may result in a decrease in later life SUD (Wilens et al. 1998). This remains speculative, as there have been no reported studies of the effects of neurofeedback treatment on prevention of SUD to date.
