Reversal of Acquired Prosopagnosia Using Quantitative Electroencephalography-Guided Laser Therapy

Publication: Photobiomodulation, Photomedicine, and Laser Surgery
Volume 40, Issue Number 3


Background: Currently treatment for prosopagnosia is limited.
Methods: We report the reversal of acquired associative-type prosopagnosia (AAP) using quantitative electroencephalography (qEEG)-guided transcranial laser therapy (qGLT) in a subject with temporal lobe epilepsy (TLE) and mild cognitive impairment (MCI).
Results: Objective and subjective measures of improvement in AAP, TLE, and MCI are presented. Additional improvement, measured through qEEG, was found 1-month post-treatment.
Conclusions: There was no recurrence of AAP for 1 year. We conclude that further research into the utility of qGLT in the treatment of AAP is warranted.
