Call for routine cognitive screening for over-50s

Annual cognitive screening for all older people should be the new normal to rule out preclinical Alzheimer’s disease, according to a leading neuropsychologist

Dr Duke Han, an associate professor of family medicine at the University of Southern California, says standard cognitive tests can detect early Alzheimer’s disease before symptoms arise, negating the need for PET scans or cerebrospinal fluid analysis up front.

He points to the results of his latest research, a meta-analysis of 61 studies, which found that people who had amyloid plaques performed worse on neuropsychological tests
