MIT scientists discover effective, non-drug treatment for Alzheimer’s disease

Cheers to the non-invasive future of medicine! Researchers at MIT have developed a protocol that uses flashing LED lights (at a precise frequency) to reduce the plaques associated with Alzheimer’s disease. Li-Huei Tsai et al. used a simple strip of LEDs to test the effects of various frequencies on the visual cortex of mice with advanced accumulation of beta-amyloid plaques. Following an hour of exposure to 40Hz flickering light for seven consecutive days, free floating amyloid plaques were markedly reduced.

Dr. Tsai’s research is groundbreaking because it uses harmless light to stimulate the natural healing processes of the brain and body. Rather than attempting to treat Alzheimer’s disease with toxic pharmaceutical drugs, the researchers discovered a way to activate the body’s natural immune response. Microglia, which account for approximately 15% of all cells found in the brain, are macrophage cells that act as the main immune defense cells for the central nervous system. Tangles formed by abnormal Tau proteins, also associated with Alzheimer’s disease, were reduced following the treatment.

Dr. Tsai’s research underscores the importance of keeping our immune systems healthy. Current research suggests that some of the best foods and supplements for overall brain health and Alzheimer’s prevention include DHA, EPA, probiotics, B vitamin complex, vitamin D, magnesium, astaxanthin, compounds found in cinnamon, coconut/MCT oil, blueberries and fresh, organic vegetables.

==================

More on the science: The LEDs worked by boosting gamma oscillations in the brain, which helped restore the natural morphology and vitality of microglia cells. The healthier microglia cells were more able to engulf amyloid plaques. In addition to failing to engulf plaques, sick microglia cells wreak havoc on other brain cells by secreting toxic chemicals.
