Biophoton Therapy Study is about testing a new light-based treatment for brain disorders like Alzheimer's, dementia, stroke, traumatic brain injury, or Parkinson's. Biophoton Therapy involves using light particles, known as photons, to influence brain function. This study checks if it helps patients feel better. The study is "triple-blinded," meaning neither the patients, doctors, nor the people giving the treatment know who's getting the real or fake treatment (called a placebo). About 80 people will stay at a research center in Butler, PA, for 4 to 6 weeks, using the treatment during sleep.

• Participants stay at the center for 4 to 6 weeks.
• No one knows who gets the real treatment first, not even the doctors.
• Tests include surveys, neurologic exams, and brain scans.

To join, you must be 18 or older, speak English, and have a brain disorder diagnosis. You cannot join if you have certain other health issues or are pregnant. Participants need a caregiver's support. This study aims to see if Biophoton Therapy is a safe and effective option for brain disorder patients.
