The present study examined whether changes of electrophysiological late event related potential pattern could be used to reflect clinical changes from therapeutic intervention with a LASER device in a group of patients with symptoms of central auditory processing disorder (CAPD). The contingent negative variation (CNV) and event related auditory cortical potentials (AERP) reflect a synchronization of together firing wired neural assemblies responsible for auditory processing, suggesting an accelerated neuromaturation process when applying a LASER device stimulation. This was discussed already in Part I of this article (1), where a model was presented explaining possible effects of LASER application of auditory neurons by inducing the respiratory chain of the mitochondria.
Part II of the article now provides clinical data, that a LASER stimulation might be useful for the clinical improvement of attention (distraction) symptoms caused by auditory processing deficits.
Subjects consisted of 59 patients average age 14 years (range 7-53 years) with normal hearing threshold, learning disability and attention deficits caused by central auditory processing disorder.
These patients were stimulated with a LASER-device system. Results after 10 LASER stimulation sessions indicated, that this type of LASER-device stimulation significantly improved auditory CNV and p200/p300 pattern morphology.
