Alzheimer's Biomarkers and Visuospatial Cognition in Parkinson's Disease: Modification by α‐Synuclein and Mediation of Age Effects

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Visuospatial deficits in Parkinson's disease (PD) often precede dementia and complicate daily functioning. Alzheimer's disease (AD) pathology and α‐synuclein aggregation frequently co‐occur in PD, but their combined impact on cognition is unclear.

Clinical Progression in Alpha‐Synuclein Positive LRRK2‐PD and Sporadic Parkinson's Disease: A Longitudinal Analysis

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background LRRK2‐Parkinson's disease (LRRK2‐PD) is biologically heterogeneous with approximately 30% lacking aggregated alpha synuclein (αSyn) in cerebrospinal fluid by seed amplification assay (SAA). Prior work has suggested slower progression in LRRK2‐PD compared to sporadic PD (sPD).

Sex Differences in Fall Frequency, Risk Factors, and Outcomes in Parkinson's Disease: A Cross‐Sectional Analysis

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Female sex is an independent fall risk factor in Parkinson's disease (PD), yet sex‐specific fall patterns remain unclear. Objectives To compare sex‐specific fall risk and outcomes across PD, prodromal alpha‐synucleinopathy (PAS), and healthy controls (HC); estimate fall frequency across PD progression; and assess how sex modifies ...

Discordance of Dopaminergic Dysfunction and Subcortical Atrophy by α‐Synuclein Status in Sporadic and Genetic Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is characterized by predominantly neuronal α‐synuclein pathology and dopaminergic dysfunction. Cerebrospinal fluid (CSF) seeding amplification assays (SAA) detect α‐synuclein aggregates in vivo, but not all patients with PD have a positive SAA.

Clinical and Imaging Characteristics of Parkinson's Disease with Negative Alpha‐Synuclein Seed Amplification Assay

open access: yesMovement Disorders, EarlyView.
Abstract Background The cerebrospinal fluid alpha‐synuclein seed amplification assay (CSFasynSAA) detects alpha‐synuclein aggregation in over 90% of individuals with sporadic PD (sPD). However, the clinical characteristics of sPD with negative CSFasynSAA remain undefined.

Early Autonomic Burden in Prodromal Parkinson's Disease Predicts Cognitive Impairment

open access: yesMovement Disorders, EarlyView.
Abstract Background Autonomic dysfunction is a known contributor to cognitive impairment in Parkinson's disease (PD), but its impact during prodromal stage is unknown. Objective The aim was to determine whether early autonomic burden predicts incident cognitive impairment in prodromal PD.

Increased Serum Neurofilament Light Chain Levels in Parkinson's Disease Patients Carrying the p.A53T SNCA Mutation: Data from the Parkinson's Progression Markers Initiative Study

open access: yesMovement Disorders, EarlyView.
Abstract Background Serum neurofilament light chain (NfL) levels, a marker of axonal damage, are generally elevated in neurodegenerative conditions, but results in idiopathic Parkinson's disease (iPD) have been inconsistent. The p.A53T SNCA mutation usually leads to a severe form of PD.

Long‐Duration Response to Levodopa in the PPMI‐Cohort

open access: yesMovement Disorders, EarlyView.
Abstract Background Treatment of Parkinson's disease (PD) with levodopa results in a sustained reduction of symptoms. Although the plasma half‐life of levodopa is short, it elicits a lasting effect, the long‐duration levodopa response (LDR). A decrease in LDR as PD progresses has been linked to motor complications, but long‐term data on the LDR and its

The Expanding Landscape of Microbiota Medicine: Indications, Therapeutic Modalities, and the Path Towards Integrative Microbiome‐Targeting Healthcare

open access: yesMicrobiota Medicine Research, EarlyView.
ABSTRACT The growing recognition of the microbiome's role in human health has propelled the emergence of microbiota medicine—a new discipline integrating microbiology, multi‐omics, and clinical science. Advances in sequencing, data integration, and interventions such as fecal microbiota transplantation (FMT) have transitioned the field from ...

What Is Required for AI to Improve the Assessment and Treatment of Patients With Lower Urinary Tract Dysfunction? ICI‐RS 2025

open access: yesNeurourology and Urodynamics, EarlyView.
ABSTRACT Introduction Artificial intelligence (AI) is poised to improve the diagnosis and management of lower urinary tract dysfunction (LUTD). Its effective deployment requires prioritization, regulatory oversight, rigorous validation, and clinician and patient engagement.
