Infrared Light Therapy as a New Approach to Dementia
A group of researchers from the United Kingdom conducted a pilot study of near-infrared transcranial PMB therapy. They used a specifically created helmet that emits infrared light. The helmet was tested on middle-aged people with mild intellectual disabilities. The results were enhanced memory, motor functions, and processing abilities.
PMB is a therapy that generally uses red or near-infrared light to evoke a response in tissues and cells. The examination of PMB started in the 1960s when scientists were using lasers for the first time to reduce pain and heal wounds. Not long ago, lasers were replaced by sources of light, such as LEDs. This means that PBM technology is now available for home use at a significantly lower cost.
In the course of the PBM therapy, the photons interact with the mitochondria. If the treatment parameters are correct, ATP levels will rise. The new PBM air-cooled helmet, Cerebrolite, is designed for home use.
Study participants were divided into two groups: treatment and placebo. The treatment group had improvements in general performance, memory, and motor functions. The participants in the placebo group experienced degradation in processing speed and had no improvement in the other categories.
Dr. Chazot, a researcher at Durham University, said that it is a safe, economical treatment for Alzheimer’s disease and other dementia types. However, this study has limitations, because after all, it is a pilot study. For instance, all of the participants were in good health. Another limitation is the lack of balance between the treatment and the placebo group.
In any case, there is a need for a large-scale study that would include a greater number of participants with different health conditions.
