Summary

Story summary

Massachusetts Institute of Technology (MIT) researchers developed gamma entrainment using sensory stimulation (GENUS) with 40Hz light and sound to slow cognitive decline in Alzheimer's disease.
In a two-year study of five participants, the late-onset group maintained higher cognitive scores and showed reduced biomarkers.
Early-onset participants did not benefit.
The therapy was safe and well-tolerated.
Results were published in Alzheimer's & Dementia, and future trials will confirm findings and broaden applicability for those at risk.
