Cognito Therapeutics is reporting that its wearable device, Spectris, raises levels of protective brain proteins in people with early Alzheimer's disease. The device works by delivering light and sound stimulation to trigger gamma-frequency brain waves — a pattern associated with healthy brain function. In a study of patients with amyloid-positive mild cognitive impairment, Spectris increased HDL-like lipid transport proteins in cerebrospinal fluid. These proteins help clear harmful lipids and may support brain resilience. The findings will be presented at the Alzheimer's Association International Conference in July 2026. Earlier studies suggested the device may slow brain shrinkage and preserve daily function. Researchers see lipid transport as a promising new pathway for protecting the aging brain.
