A non-drug and non-invasive approach, using sound and light, would eliminate amyloid plaques. Despite the accumulation of promising experimental results, this hypothesis continues to be debated.
Could simple visual and auditory stimulations slow the progression of Alzheimer’s disease? Or to put it even more simply, might sound and light succeed where so many medications have failed? This is a hypothesis that has been in vogue for several years, but is still debated in the scientific community. Experimental data, published in the journal Nature on February 28, nevertheless provide new convincing elements in favor of this “sensory gamma stimulation”, which is still little known.
The person who led this work is none other than Li-Huei Tsai, professor at the Massachusetts Institute of Technology (Boston – United States) and director of the Picower Institute for Learning and Memory. This specialist in Alzheimer’s disease has been working for around ten years on the cerebral effects of sensory stimulation, particularly in neurodegenerative diseases. She conducted the first studies…
