Transcranial Near-Infrared Light in Healthy Subjects: a Cerebral Blood Flow Study With Diffuse Correlation Spectroscopy — NIR-Flow  

Cognitive Change Clinical Trial

Official title:
Transcranial Near-Infrared Light in Healthy Subjects: a Cerebral Blood Flow Study With Diffuse Correlation Spectroscopy

Clinical Trial Summary

Transcranial Light Therapy involves non-invasive and invisible beams of light that increase energy metabolism in the brain. Transcranial light therapy has been found to promote brain metabolism. The purpose of the study is: To asses the change in cerebral blood flow induced by the Transcranial Continuous and Pulse Near-Infrared Light Therapy in healthy subjects. To correlate with cognitive performance the change in cerebral blood flow induced by the Transcranial Continuous and Pulse Near-Infrared Light Therapy in healthy subjects. To correlate with skin pigmentation the change in cerebral blood flow induced by the Transcranial Continuous and Pulse Near-Infrared Light Therapy in healthy subjects. To assess the safety and tolerability of the Transcranial Continuous and Pulse Near-Infrared Light Therapy in healthy subjects

Clinical Trial Description

During study visits a clinician applies transcranial light therapy to both sides of a participant's forehead for about 30 minutes. The study involves, 1 screening visit which may last up to 3 hours, 3 transcranial light therapy treatment visits, and 1 posttreatment visit (5 total visits to the Massachusetts General Hospital). All eligible participants will have 1 visit with continuous light, 1 visit with pulsed light, and 1 visit with sham light. Cerebral blood flow will be measured before and after each light session using DCS-spectroscopy. During sham transcranial light therapy visits, the transcranial light therapy device will not produce near infrared waves (e.g., light energy that cannot penetrate the skin and cranium). The participant will not know which treatment is received at each visit. ;
