The New York Times - For Alzheimer’s, Detection Advances Outpace Treatment Options
A new brain scan technology, which went on the market in June, is spreading fast. The scans show plaques in the brain — barnaclelike clumps of protein, beta amyloid — that, together with dementia, are the defining feature of Alzheimer’s disease. Those who have dementia but do not have excessive plaques do not have Alzheimer’s. It is no longer necessary to wait until the person dies and has an autopsy to learn if the brain was studded with plaques. At The Mount Sinai Medical Center in New York, Dr. Samuel E. Gandy has been ordering at least one a week for people with symptoms ambiguous enough to suggest the possibility of brain plaques. Dr. Gandy said that as many as 30 percent of people who seem to have Alzheimer’s turn out not to have it when they get the scan.
