Comparing Clinical Profiles in Alzheimer's Disease and Parkinson's Disease Dementia
Background: Greater understanding of differences in baseline impairment and disease progression in patients with Alzheimer's disease (AD) and Parkinson's disease dementia (PDD) may improve the interpretation of drug effects and the design of future studies. Methods: This was a retrospectiv...
