"Multisensory Stimulation Clears Amyloid and Slows Alzheimer's Progression"
Multisensory 40 Hz gamma stimulation has been found to promote glymphatic clearance of amyloid in the brain, potentially offering a therapeutic intervention for Alzheimer's disease. This stimulation increased arterial pulsation, CSF influx, and meningeal lymphatic vessel diameter, leading to enhanced clearance of amyloid. The stimulation also modulated astrocytic endfeet, promoting AQP4-dependent glymphatic clearance of amyloid. These findings suggest that noninvasive gamma stimulation may have a role in promoting brain health and potentially alleviating Alzheimer's disease pathology.
