JAMA - Amyloid & Dementia

"Prevalence of Cerebral Amyloid Pathology in Persons Without Dementia
A Meta-analysis"

"Conclusions and Relevance  Among persons without dementia, the prevalence of cerebral amyloid pathology as determined by positron emission tomography or cerebrospinal fluid findings was associated with age, APOE genotype, and presence of cognitive impairment. These findings suggest a 20- to 30-year interval between first development of amyloid positivity and onset of dementia."
