Evidence that 40Hz gamma stimulation promotes brain health is expanding

A decade of peer-reviewed studies from MIT's Picower Institute and independent labs worldwide show 40Hz sensory stimulation reduces Alzheimer's pathology (amyloid, tau proteins) in mice, prevents neuron death, and phase II clinical trials demonstrate significant slowing of brain atrophy and cognitive improvements in human Alzheimer's patients. Multiple independent research teams (China, Harvard Medical School, Scotland) have corroborated results using different stimulation methods.

Phase III clinical trial results are not yet published; mechanisms underlying the treatment are still being explored; efficacy for other neurological conditions (Parkinson's, stroke, epilepsy, MS) remains speculative with only preliminary evidence; long-term safety and optimal protocols not yet established.
