Examining the Impact of Photobiomodulation on Cognition, Behavior, and Biomarkers of Alzheimer's Disease
In Brief
A clinical study evaluating Vielight Neuro Gamma and Sham Vielight Neuro Gamma for Alzheimer Disease. Completed, enrolled 23 participants across 2 sites.
Detailed Summary
Photobiomodulation (PBM) describes the use of near-infrared light (which is not visible to the eye) to heal and protect tissue that has either been injured, is degenerating, or else is at risk of dying. Research suggests that the light delivered during PBM enhances the body's biochemical ability to store and use energy and increase blood flow, which triggers the body's natural healing processes. The primary goal of this study is to determine if PBM administered transcranially (through the scalp and skull) and intranasally (inside the nose) with a commercially available device is safe and tolerable for patients with mild-to-moderate Alzheimer's disease (AD). Secondary goals are to examine whether tPBM has an effect on cognitive function and behavioral symptoms in patients with AD and whether tPBM has an effect on fluid biomarkers of AD. A biomarker is a specific physical trait used to measure the progress of a disease or condition.

Interventions
The Vielight Neuro Gamma is headset that delivers transcranial (through the scalp and skull) and intranasal (through the nose) near infrared (NIR) light. The device is engineered for increased efficacy and easy domestic use for comprehensive brain photobiomodulation (PBM). The NIR lights are pulsed at a 40 Hz rate, which correlates with electroencephalogram (EEG) gamma brain wave entrainment.
The Sham Vielight Neuro Gamma headset is identical to the active Vielight Neuro Gamma headset and intranasal light emitting diode (LED) except it has a power output of 0.
