DALLAS: A research team has successfully used blue LED light to suppress a known cause of Alzheimer’s disease: plaque of beta-amyloids, a protein commonly found in the brain.
Light-induced treatments using organic photosensitizers have the advantages of restricted treatment time and area. In the case of cancer treatments, doctors use photodynamic therapies where a patient is injected with an organic photosensitizer and a light is shed on the patient’s lesion. However, such therapies had never been employed to treat neurodegenerative diseases.
