Quantitative EEG as outcome measure of the therapeutic effects of transcranial pho-tobiomodulation: A systematic review

Background: Transcranial Photobiomodulation (t-PBM) is a current, innovative method that used in the therapy of many neurological and psychological diseases. Its mechanisms action have been investigated most well described ways are its effects on mitochondrial function heat/light-activated ion channels neurons membrane. It has suggested increase cerebral blood flow alterations membrane dominant potential cause PBM quantitative electroencephalography (qEEG), some recent studies reported. Aim: The aim this review to describe t-PBM brain oscillations, as these measured by qEEG. Methods: research was carried out Pubmed database it included all had published until February 2022. Results: Overall, sixty-eight were located considered, searching with terms or Light Therapy Near Infrared EEG. Only eleven them order observe effect can human Two reported EEG after application hand instead head. Thus, nine review, which applied observed brought upon qEEG healthy adults patients memory problems. Conclusion: showed increases high frequency neural activity inhibits low oscillations. varied lot light parameters itself, their study population.
