Unified Parkinson’s Disease Rating Scale (UPDRS) motor score subscale trajectories in Dementia with Lewy Bodies and Parkinson Disease Dementia in a community autopsy cohort

We previously reported that in our autopsy‐confirmed cohort of Dementia with Lewy Bodies (DLB), Parkinson’s Disease Dementia (PDD) and Alzheimer’s Disease (AD), DLB with parkinsonism (DLB+Park) predicted faster progression of UPDRS‐III scores compared to PDD, DLB without parkinsonism (DLB‐Park), and AD. This study examined annualized rate of change of UPDRS‐III subscales in our cohort.
