Serum p‐tau217 Is a Prognostic Indicator of Cognitive Impairment in Idiopathic REM Sleep Behavior Disorder

open access: yesAnnals of Neurology, EarlyView.
Objective Assess the performance of serum phosphorylated tau 217 (p‐tau217) and neurofilament light chain (NfL) in predicting risk of cognitive impairment or phenoconversion to dementia in individuals with iRBD. Methods We measured serum p‐tau217 and NfL levels by electrochemiluminescence across 4 polysomnographically confirmed iRBD cohorts (n = 300 ...

Clinical biomarkers for Lewy body diseases

open access: yesCell & Bioscience, 2023
Synucleinopathies are a group of neurodegenerative disorders characterized by pathologic aggregates of neural and glial α-synuclein (α-syn) in the form of Lewy bodies (LBs), Lewy neurites, and cytoplasmic inclusions in both neurons and glia.

Protein Aggregates and Polyglutamine Tracts In Neurodegenerative Disease [PDF]

open access: yes, 2018
The incidence of neurodegenerative diseases such as Alzheimer\u27s Disease, Parkinson\u27s Disease, Huntington\u27s Disease and other Polyglutamine Diseases is projected to dramatically increase throughout the developed world, and yet the pathology of ...

C-elegans model identifies genetic modifiers of alpha-synuclein inclusion formation during aging [PDF]

open access: yes, 2008
Inclusions in the brain containing alpha-synuclein are the pathological hallmark of Parkinson's disease, but how these inclusions are formed and how this links to disease is poorly understood.

Toward Harmonizing Quantification of Dopamine Neuron Imaging Biomarkers in Parkinson's Disease: The Centamine Scale

open access: yesAnnals of Neurology, EarlyView.
Objective Dopaminergic imaging is a key biomarker for both the investigation of the biology of Parkinson's disease and related synucleinopathies and the evaluation of potential therapies in clinical trials. This work presents a harmonized approach for quantifying dopaminergic molecular imaging tracers, such as [123I]ioflupane (dopamine transporter scan

Depopulation of dense α-synuclein aggregates is associated with rescue of dopamine neuron dysfunction and death in a new Parkinson's disease model.

open access: yes, 2019
Parkinson's disease (PD) is characterized by the presence of α-synuclein aggregates known as Lewy bodies and Lewy neurites, whose formation is linked to disease development. The causal relation between α-synuclein aggregates and PD is not well understood.

The Phenotypic Spectrum of Sporadic Creutzfeldt‐Jakob Disease Cortical Subtype

open access: yesAnnals of Neurology, EarlyView.
Objective The objective of this study was to characterize the phenotypic spectrum of the rare sporadic Creutzfeldt‐Jakob disease cortical subtype (sCJDMM/MV2C) in a large multicentric autopsy cohort. Methods We evaluated clinical histories, biofluid markers, brain diffusion‐weighted (DW)‐magnetic resonance imaging (MRI), and electroencephalogram (EEG ...

Environmental risk factors provoke new thinking for prevention and treatment of dementia with Lewy bodies

open access: yesHeliyon
In recent years, environmental factors have received attention in the pathogenesis of neurodegenerative diseases. Other than genetic factors, the identification of environmental factors and modifiable risk factors may create opportunities to delay the ...

Improving the clinical detection of Lewy body dementia with the Lewy body composite risk score

open access: yesAlzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, 2015
Introduction Dementia with Lewy bodies (DLB) is a challenge to diagnose, particularly outside of expert centers with long delays in diagnosis leading to significant burden to patients and caregivers. Although consensus criteria have excellent specificity,

α-Synuclein pathology in post-mortem retina and optic nerve is specific for α-synucleinopathies

open access: yesnpj Parkinson's Disease, 2023
There is increasing interest in studying retinal biomarkers for various neurodegenerative diseases. Specific protein aggregates associated with neurodegenerative diseases are present in the retina and could be visualised in a non-invasive way. This study
