Brain scans lead to misdiagnosis of Alzheimer's disease
This is the first study to my knowledge to present objective evidence suggesting caution about the use of brain scans to make a diagnosis of Alzheimer's disease. The unique thing about this study was that the scans were done on community dwelling participants (mean age of about 64). Studies used to make the case for the accuracy of scans have so far only used highly selected participants — a sampling bias that distorts results. - naplesnews.com
