CAA: cerebral amyloid angiopathy; DLB: dementia with Lewy bodies; F: females; LB: Lewy body; M: males; NBV: normalized brain volume; NFT: neurofibrillary tangles; NGMV: normalized grey matter volume; NWMV: normalized white matter volume; PD: Parkinson’s disease; PDD: Parkinson’s disease dementia; SD: standard deviation. *P < 0.05, **P < 0.01, ***P < 0.001 when compared to controls, and ϮϮP < 0.01 when compared to the PD group
