Alzheimer’s is the most common type of dementia and unfortunately there is no cure for this disease. Its treatment typically focuses on improving the quality of life of the patients or slowing down the symptoms. Some studies suggest that exposure to flickering lights may help fight the disease. Gamma brainwaves - electrical activity in the brain - helps connect and process information in the brain. These gamma waves are diminished in people with Alzheimer's disease. Researchers suggest that exposure to lights flickering may improve gamma-wave brain activity and help eliminate beta-amyloid plaques. These plaques are a key hallmark of Alzheimer’s.
