The prevalence of amyloid pathology in non-demented subjects: a meta-analysis Lead Investigator: Willemijn Jansen Institution : Maastricht University E-Mail : willemijn.jansen@maastrichtuniversity.nl Proposal ID : 361 Proposal Description: Amyloid pathology in nondemented individuals might reflect an early stage of Alzheimer???s disease (AD). Prevalence estimates of amyloid pathology differ widely across studies. We aim to estimate the prevalence of amyloid pathology in non-demented individuals as assessed by amyloid-PET imaging, CSF amyloid-beta and neuropathological investigation with a meta analysis.
