By applying sound and light at the same frequency, the cognitive function can be improved, and also helps remove plaque displaying symptoms of the disease.
The treatment has at the moment been used in mice and now is intended to be tested in humans.
The practical applications of the method seem limited though, as the effect is limited to visual parts of the brain, bypassing important zones that are key in memory formation and retrieval. Also, considering the differences between mice and humans, it will imply more work to scale the treatment, but the findings have encouraging implications for future development.
This research, run by MIT, proved that this treatment provokes gamma frequencies in the brain (people suffering from Alzheimer’s have an impedance of these gamma waves), stimulates the hippocampus —which is believed to modulate short-term memory— and helps keep remote regions in sync.
The hopes are that this could become an inexpensive way, drug-free, to treat Alzheimer.
