X-Ray May Detect Alzheimer's Disease Early
Researchers have developed a highly detailed x-ray machine that can detect Alzheimer’s disease early. Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory developed the x-ray technique in hopes of helping scientists track dense areas of protein that form in the brain of Alzheimer’s disease patients, called amyloid beta (Aß) plaques. The x-ray could aid in the development of drugs to remove the harmful proteins that lead to cognitive decline associated Alzheimer’s disease.
Amyloid beta plaques are tiny, and cannot be found with current brain imaging techniques. The research is the first to use the x-ray technique, previously used to find small tumors in the breast, and in cartilage and joints of the knee and ankle. The x-ray would prove to be an inexpensive way to find miniscule plaques, identifying Alzheimer’s disease in patients before it progresses, while tracking the progress of drugs that might be developed for treatment.
