Risk factors for earlier dementia onset in autopsy‐confirmed Alzheimer's disease, mixed Alzheimer's with Lewy bodies, and pure Lewy body disease

Abstract

Male sex and APOE ɛ4 alleles increase risk for earlier dementia onset in AD but not LBD. Depression increases risk for earlier dementia onset in AD, LBD, and AD + LBD, but evaluating the course, treatment, and severity is needed in future studies.
