A pilot study hints that flickering light and sound may help treat Alzheimer’s by restoring connectivity in the brain and mobilizing the immune system.

There were assumptions that flickering light and sound waves can trigger brain function and have a negative effect on the person.

The promise of flickering light to treat Alzheimer's takes another step forward in this new study, which reveals stark biochemical mechanisms: 40 Hertz stimulus triggers a marked release of ...

Hope may be in sight for millions of Alzheimer's patients as scientists have found a way to slow disease progression and treat its symptoms using only light and sound.

Fascinatingly, the researchers then discovered similar effects could be generated in the mouse brain through simple external exposure to a light flickering at 40 Hz.
