Rare‐Variant Burden across Lysosomal Genes Implicates Sialylation and Ganglioside Metabolism in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Lysosomal dysfunction is central to Parkinson's disease (PD) pathogenesis, with GBA1 representing the strongest established genetic risk factor. Numerous other genes involved in lysosomal sphingolipid, glycosphingolipid, and ceramide metabolism have been proposed as contributors to PD, highlighting the need for genetic analyses ...

Plasma p‐tau217 Versus p‐tau181 in Parkinson's Disease: Differential Associations with Alzheimer's Disease‐Related Neurostructural Changes and Cognitive Function

Movement Disorders, EarlyView.
Abstract Background Plasma phosphorylated‐tau at threonine‐217 (p‐tau217) and threonine‐181 (p‐tau181) are scalable, minimally invasive biomarkers of Alzheimer's disease (AD) pathology. In Parkinson's disease (PD), AD co‐pathology may contribute to its clinical heterogeneity.

Spatiotemporal Progression Patterns of Striatal Dopamine Depletion and Cerebral Hypoperfusion in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background The identification of Parkinson's disease (PD) subtypes is crucial for predicting the disease course and designing personalized therapeutic strategies. Objectives The aim of the study was to characterize the heterogeneity of the spatiotemporal evolutionary patterns of striatal dopamine depletion and cerebral hypoperfusion in PD ...

Association Between Plasma Phosphorylated Tau‐217 and Cognition in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Alzheimer's disease (AD) co‐pathology contributes to dementia in PD, but its role in earlier cognitive impairment remains uncertain. Objective To determine if p‐tau217, a biomarker of early AD, is associated with cognitive impairment in PD.

Greater Motor and Nonmotor Burden at Diagnosis Is Associated With Amyloid Copathology in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Concurrent Alzheimer's disease pathology is increasingly recognized as a poor prognostic factor in Parkinson's disease (PD), yet reliable clinical indicators for early identification of AD copathology remain poorly established.

Rare‐Variant Burden Analysis of Dystonia Genes in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Dystonia frequently coexists with Parkinson's disease (PD), yet the extent of genetic overlap remains insufficiently explored. Objective The aim was to examine whether rare variants in dystonia‐related genes are associated with PD or early‐onset PD (EOPD).

Apathy in Lewy Body Disorders: A Position Paper

Movement Disorders, EarlyView.
Abstract Apathy is one of the most prevalent and disabling non‐motor symptoms in Parkinson's disease (PD) and dementia with Lewy bodies (DLB), collectively referred to as Lewy body disorders (LBDs). It is associated with reduced quality of life, accelerated cognitive decline, increased caregiver burden, and poorer functional outcomes, yet remains ...
