Dementia is increasingly being recognized in cases of Parkinson's disease (PD); such cases are termed PD dementia (PDD). The spread of fibrillar α-synuclein (α-syn) pathology from the brainstem to limbic and neocortical structures seems to be the strongest neuropathological correlate of emerging dementia in PD. In addition, up to 50% of patients with PDD also develop sufficient amyloid-β plaques and tau-containing neurofibrillary tangles for a secondary diagnosis of Alzheimer's disease (AD), and these pathologies may act synergistically with α-syn pathology to confer a worse prognosis. Understanding the relationships between these three distinct pathologies and their resultant clinical phenotypes are crucial to the development of effective disease-modifying treatments for PD and PDD.
