Quantitative Assessment of Visible Nigrosome‐1 in Patients with Parkinson's Disease
Movement Disorders Clinical Practice, EarlyView.Abstract Background
The nigrosome‐1 (N1) sign on susceptibility‐weighted imaging (SWI) typically disappears in Parkinson's disease (PD), though some patients can show uni−/bilaterally preserved N1. Objective
Investigating whether visible nigrosomes in PD patients differ from those of healthy subjects (HC). Methods
Forty‐eight PD and 35 HC underwent 3 T‐Maria Eugenia Caligiuri, Ilaria Chimento, Marida De Maria, Emma Biondetti, Jolanda Buonocore, Valerio Riccardo Aquila, Maria Celeste Bonacci, Emanuele Tinelli, Umberto Sabatini, Aldo Quattrone, Andrea Quattrone +10 morewiley +1 more sourceAlzheimer's Biomarkers and Visuospatial Cognition in Parkinson's Disease: Modification by α‐Synuclein and Mediation of Age Effects
Movement 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.David Ledingham, Sahana Sathyanarayana, Charlotte B.

The Journal of biological chemistry, 2003 alpha-Synuclein is a small cytosolic protein of presynaptic nerve terminals composed of seven 11-residue repeats and a hydrophilic tail. alpha-Synuclein misfolding and dysfunction may contribute to the pathogenesis of Parkinson's disease and neurodegenerative dementias, but its normal folding and function are unknown.Chandra, S., Chen, X., Rizo, J., Jahn, R., Suedhof, T. +4 moreopenaire +2 more sourcesClinical Progression in Alpha‐Synuclein Positive LRRK2‐PD and Sporadic Parkinson's Disease: A Longitudinal Analysis
Movement 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).Lucy A. Morse, Seung Ho Choi, Caroline Gochanour, David‐Erick Lafontant, Lana M. Chahine, Kalpana M.

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 ...Joaquin A.

Movement 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.Michael Tran Duong, Sandhitsu R.
