- Percent change of cerebral blood flow (CBF) [ Time Frame: Baseline, Visit 18 (Week 10) ]
Cerebral blood flow (CBF) is measured as Blood oxygen Level Dependent (BOLD) signal on functional magnetic resonance imaging (fMRI). BOLD signal reflect changes in regional cerebral blood flow that delineates regional activity, A positive BOLD signal marks an increase in regional blood flow while a negative BOLD signal marks a decrease in regional blood flow. A positive percent change indicates that blood flow increased in the region of interest between scans, a negative percent change indicates blood flow decreased between scans.
- Change in the Montgomery-Asberg Depression Rating Scale (MADRS) score [ Time Frame: Baseline, Visit 17 (Week 9, endpoint) ]
Montgomery-Asberg Depression Rating Scale (MADRS) is a 10-item diagnostic questionnaire that psychiatrists use to measure the severity of depressive episodes in patients with mood disorders. Each item is rated on a 0-6 scale, resulting in a total score range of 0-60. The higher the score, the more severe the depression.

Transcranial Near Infrared Radiation and Cerebral Blood Flow in Depression - R33
|
Transcranial Near Infrared Radiation and Cerebral Blood Flow in Depression - R33
|
The purpose of this research study is to determine if application of near infrared energy to the forehead can change blood flow in the brains of people with depression. Near infrared energy is like light but is not visible to the human eye.
|
In this multi-center study, approximately 60 subjects with Major Depressive Disorder (MDD) will undergo Magnetic Resonance Imaging (MRI) scanning during transcranial Photobiomodulation (tPBM) before and after a randomized, double-blinded, controlled 16 session course of treatment with tPBM or sham.
