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

Movement 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.

Quantitative Analysis of Locus Coeruleus Neurons and Thalamic Noradrenergic Axons in a Progressive 1‐Methyl‐4‐phenyl‐1,2,3,6‐tetrahydropyridine Monkey Model of Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Parkinson's disease is mainly characterized by dopaminergic neurodegeneration in the substantia nigra pars compacta (SNc) and α‐synuclein accumulation. The locus coeruleus (LC) is also affected in Parkinson's disease and linked to some nonmotor symptoms, but the extent and timing of its degeneration remain unclear.

Altered Cerebrospinal Fluid Tryptophan–Kynurenine Pathway Metabolism in Multiple System Atrophy

Movement Disorders, EarlyView.
Abstract Background Alterations in tryptophan–kynurenine (TRP‐KYN) metabolism, which is associated with neuroinflammation, remain unclear in multiple system atrophy (MSA). Objective The aim was to investigate cerebrospinal fluid (CSF) TRP metabolites in MSA and their associations with other biomarkers.

In Vivo Mapping of Catecholaminergic Loss and Iron Deposition in Huntington's Disease

Movement Disorders, EarlyView.
Abstract Background The pathophysiology of Huntington's disease (HD) remains obscure. Magnetic resonance imaging (MRI) can reveal in vivo molecular changes related to disease pathology. Objectives To investigate catecholaminergic neuronal integrity and subcortical brain iron accumulation in HD employing neuromelanin‐sensitive MRI, and quantitative ...
