NCT03750409 · ACTIVE NOT RECRUITING
Assessing Feasibility of Prolonged Repetitive Near Infrared Light Stimulation in Early to Mid-Stage Dementia
This trial is testing whether a light-emitting helmet that delivers infrared and near-infrared light to the brain can support brain cell activity and self-repair in people already living with mild to moderate Alzheimer's-type dementia. It is a feasibility study, meaning the goal is simply to see whether the approach is practical and safe enough to study further. No drug is involved. Details beyond that are limited.
You may qualify if
- Aged 50-85 years with an independently provided diagnosis of dementia, probable Alzheimer's type.
- Dementia symptoms not greater than early to mid-stage dementia
- Generally healthy as indicated by recent physical examination within the last 6 months
- If labs are available within the last 6 months, renal function, hepatic function, cardiac function should be normal
You're excluded if
- Diagnosed actively growing intracranial pathology (tumors etc.)
- Misusing illegal substances or alcohol
- Previous history of stroke
- History of aggression or violence
- History of major psychiatric illness
- No underlying CNS pathology (confined to tumor, epilepsy only)
