Effects of Transcranial Photobiomodulation in ADHD
Sponsor: University of Texas at Austin
Summary
The investigators have previously shown that non-invasive methods of brain stimulation such as the administration of transcranial infrared light to the prefrontal cortex (PFC) can result in improvements to cognition and emotion as well as brain oxygenation. This method is called transcranial photobiomodulation (tPBM). The investigators hypothesize that tPBM can improve cognition and brain oxygenation in adults with attention deficit hyperactivity disorder (ADHD). The investigators will investigate the effects of repeated tPBM sessions on cognitive functioning in adults with ADHD. Specifically, the investigators hypothesize that participants that receive tPBM will show improvements in response control, sustained attention, and working memory, as well as improvements in prefrontal hemodynamics and a reduction in ADHD symptoms.

Interventions
Active transcranial photobiomodulation
Active transcranial photobiomodulation to the forehead targeting prefrontal cortex involves administration of 1064-nm light delivered via laser with a 4 centimeter beam diameter and 250 mW/cm2 power density for 8 minutes per treatment.
Sham transcranial photobiomodulation
Identical procedure as active group, but without 1064-nm light emitted by the device.
