Summary

This study tested a light therapy called transcranial photobiomodulation (tPBM) to see if it could safely reduce autistic traits and ADHD symptoms in children and teens. 38 participants aged 9 to 17 with ADHD and at least moderate autism symptoms received the treatment. The goal was to measure changes in ADHD and social behavior scores, and to check for any discomfort from the device.
