People who declined to participate in a prospective study of aging developed dementia more quickly than those who joined the study…Among participants in the study, dementia was diagnosed at a rate of 19.1 per 1,000 person-years, compared with 23.6 per 1,000 person-years among those who refused participation but who had previously allowed their medical records to be reviewed for research purposes, said David Knopman, MD, of the Mayo Clinic in Rochester, Minn.
