Last summer, I wrote about a light and sound therapy to help those with Alzheimer’s disease. Here is an excerpt from that article.

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.

Another leap forward in the battle against dementia has been achieved using infrared light. Late last year, a Durham University study showed that motor function and processing skills improved with light therapy.

Transcranial PBM-T (Photobiomodulation therapy) uses an infrared wavelength at 2068 nanometers twice daily for six minutes each time. The pilot study was very promising, and it is believed that the memory performance achieved could be beneficial to both those with and without dementia. The study was published in the Photobiomodulation, Photomedicine and Laser Surgery Journal

A control group and a placebo group were tested for one month. Significant improvement was noted in the control group. Motor function, memory, and brain processing speed improved. A helmet delivered infrared light directly into the cranium. It is believed that dying brain cells are regenerated into fully functional cells.


I have written over 40 articles on Alzheimer’s and other neurodegenerative diseases. In the past month, new studies have revealed potential new ways to diagnose or treat dementia. This study looks promising, and I hope that the follow-on clinical studies prove successful in treating Alzheimer’s and other related diseases.

  1. Good day! Do you know if they make any plugins to assist with SEO?
    I’m trying to get my blog to rank for some targeted keywords but I’m not seeing very good gains.
    If you know of any please share. Cheers! I saw similar article here:
