The present autism rate in the US is 1 in 150. New Jersey has the highest rate in the nation and stands at 1 in 90. There have been several preliminary investigations into how the autistic child appears on a QEEG examination. The results have presented a diverse set of findings from paucity in the alpha frequency to issues of connectivity problems between different regions of the brain with a focus on the left hemisphere in one study. The diversity of findings only renders it more important to understand that each case needs to be addressed individually, although some consistent global patterns may be documented in the future.
Of particular importance to note, however, is that the attempt to ameliorate the symptoms through the use of EEG biofeedback has been promising. In one study (presently in peer review process) the intervention resulted in a 40% reduction in symptoms (on parent questionnaires) following 20 sessions. This is an encouraging result, given the fact that the most well known intervention (ABA) for autism consume years of intervention.
