Light waves are able to treat Alzheimer’s patients.

I wrote several articles last week on Alzheimer’s disease (AD) and was delighted to see new information on the treatment of AD today – with light and sound. Some diseases are treated with light or sound, such as skin rashes, seasonal affective disorder, sleep issues, jet lag, and more. For example, Parkinson’s disease research shows positive results with light therapy.

Sound (ultrasound) is used to treat neuropathies, depression, epilepsy, traumatic brain injury, etc.

Modulated Light & Sound Alzheimer’s patients were exposed to a rhythmic brain pattern focused on gamma rays, the fast brain activity. It is where we learn, process, and remember.

Scientists found reductions in amyloid plaque by using visible light flashes at 40 Hz manipulated gamma brain waves. The testing was successful on laboratory animals, and human testing began using synchronized audio with the flashing light. In addition, a placebo white noise and random light flashes were used as a placebo.

Results After three months of human studies using light and sound, the brains of AD patients showed improvement – brain degeneration slowed. No side effects were noted.

A second study was done for six months with about five times the number of AD patients. A similar placebo treatment was incorporated into the test. The placebo group in both studies showed no improvement in the progression of AD. This second study noted a 65% improvement in disease progression.


The light and sound show appears to be an excellent non-invasive option for further clinical trials. All reports indicate that it is safe and tolerated well by those being tested.

  1. Great info on the slowing in the progression of AD. Might this technology be introduced to nursing homes and other facilities caring for AD patients?
    This comment box is really great.
