Study data is beginning to support the idea that apparently healthy people who believe something is off with their memory or cognitive abilities may be picking up on very early signs of dementia or may be more likely to develop the condition. "These people are sensing something, and there's some biological signals that correlate," said Dr. Ronald Petersen of the Mayo Clinic's Alzheimer's center. Subjective screening criteria could be useful in clinical trials of treatments intended for people at higher risk of developing dementia.
