Near-infrared light therapy for brain function in adults
Part of Brain & nervous system, Mental health clinical trials.
This study tests whether shining a special near-infrared light on the head can improve how well your brain works and how clearly you think. It is for healthy younger and older adults who want to help find new ways to support brain health.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 21 and 85 years old.
- You can see and hear well enough to do the tests (with glasses or hearing aids if needed).
- You can read and write in English.
- You do not have an active brain disease like multiple sclerosis, uncontrolled seizures, or brain cancer.
- You have not had a stroke (other than a mini-stroke) in the last 60 days.
- You are not currently using a brain stimulation device (like tDCS, TMS, etc.) or taking certain supplements for brain blood flow (like NAD, NR, L-citrulline, urolithin).

This study tests whether light therapy can help improve thinking and memory in older adults with mild cognitive changes. Researchers will use light exposure to see if it supports brain health in people with signs of blood vessel disease in the brain.
This study tests how non-invasive near-infrared light may affect brain function. You may be able to join if you’re an adult, since there are no other listed eligibility restrictions.
This trial studies a non-invasive light therapy (transcranial photobiomodulation) applied to the scalp to see how it affects brain activity. It is for young, healthy volunteers to find the best light frequency.
This study tests a non-invasive light therapy on the head to see if it can safely change brain activity and improve fine hand movements in healthy young adults.
This study tests a light-based therapy (photobiomodulation) applied to the head to see if it can improve thinking and memory by boosting energy in brain cells. It may help healthy adults sharpen their cognitive abilities.
This study tests whether a painless light therapy applied to the head can help older adults (55-85) who had a moderate or severe traumatic brain injury 1-2 years ago. It aims to see if the treatment improves thinking and memory.
