Study 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 which may help people with anxiety. The research team proposes a novel approach to treating anxiety by using transcranial light therapy.
Primary Outcome
This instrument is completed by the clinician based on his/her assessment of the patient's anxiety symptoms, using a structured interview, specific instructions, and defined anchor points. Answers to the questions are rated on a scale of 0-4, with higher scores indicating more severe pathology. Scores range between 0 to 56; \<17 indicates mild severity, 18-24 mild-to-moderate severity, and 25-30 moderate to severe.
