PET imaging tracer binds to plaque in the brain to identify Alzheimer’s disease, University of Pittsburgh study finds
A new innovation in brain scans could help detect Alzheimer’s disease in its early stages.
Alzheimer’s disease (AD) is the most common form of dementia, or cognitive decline that interferes with daily life. Symptoms of Alzheimer’s disease include memory issues, confusion about time and place, mood changes and eventually physical symptoms such as difficulty walking and swallowing. Most Alzheimer’s disease patients are over the age of 65.
One characteristic of the disease is the development of plaques in the brain. Amyloid plaques are collections of protein that build up in between nerve cells, according to the Alzheimer’s Association. Recent studies have discovered that the disease could be detected early with the help of materials that can bind to brain plaque during PET, or positron emission tomography, scans which take pictures of the brain.
