Transcranial infrared light to the prefrontal cortex for adults with ADHD

Effects of Transcranial Photobiomodulation on Cognition and Brain Metabolism in Adults With ADHD

NA · University of Texas at Austin · NCT07203092

This trial will try using transcranial infrared light on the prefrontal cortex to see if it improves attention, impulse control, and working memory in adults with ADHD.

What this trial studies

This double-blind, sham-controlled trial randomizes adults aged 18–44 with a medical history of ADHD to receive either active or sham transcranial photobiomodulation (tPBM) to the prefrontal cortex. Participants receive three weekly in-person sessions using a 1064 nm laser, with cognitive testing (continuous performance task and 2-back) performed at baseline and after the final session. Functional near-infrared spectroscopy (fNIRS) is recorded before and after treatment to measure prefrontal hemodynamics and connectivity, and ADHD symptoms are tracked with the Adult ADHD Self-Report Scale at baseline, post-treatment, and four-week follow-up. The protocol allows participants on stable ADHD medication regimens or not taking medication, and includes one remote follow-up visit.

Who should consider this trial

Good fit: Ideal candidates are English-speaking adults aged 18–44 with a medical diagnosis of ADHD who can attend three in-person sessions in Austin and either are on a stable ADHD medication regimen or are not taking medication.

Not a fit: People who are pregnant, who received any photobiomodulation within the past five weeks, who cannot travel to Austin, or who have unstable ADHD medication changes are unlikely to qualify or benefit from this protocol.

Why it matters

Potential benefit: If successful, this noninvasive, non-drug approach could improve attention, impulse control, working memory, and reduce ADHD symptoms for some adults.

How similar studies have performed: Prior small studies of transcranial photobiomodulation have reported improvements in cognition and prefrontal oxygenation, but randomized sham-controlled evidence specifically in ADHD is limited.
