Neurofeedback, has been used successfully for the treatment of substance abuse for over 25 years. Built on the work of Kamiya and Green (Budzynski, 1999), Eugene Peniston published a series of papers using alpha-theta neurofeedback with a Veteran’s Administration (VA) population of Vietnam War veterans diagnosed with alcohol abuse and post-traumatic stress disorder (PTSD) (Peniston & Kulkosky, 1989; Peniston & Kulkosky, 1990; Peniston, Marrinan, Deming, & Kulkosky, 1993). These important ‘Peniston papers’ no doubt facilitated a wave of EEG practitioners who rely on alpha-theta neurofeedback, or its modified forms, to treat substance abuse (as well as PTSD) that continues to this day.
