Evolution of prodromal Parkinson’s disease and dementia with Lewy bodies: a prospective study [PDF]
Brain, 2019 Abstract Parkinson’s disease has a long prodromal stage with various subclinical motor and non-motor manifestations; however, their evolution in the years before Parkinson’s disease is diagnosed is unclear. We traced the evolution of early motor and non-motor manifestations of synucleinopathy from the stage of idiopathic rapid eye ...

Focused Ultrasound for the Treatment of Circuit and Molecular Pathology in Parkinson's Disease
Movement Disorders, EarlyView.Abstract Focused ultrasound is rapidly emerging as a novel technology for the development of symptomatic therapies and supporting disease‐modifying treatments for Parkinson's disease (PD). At the forefront of this development is thermoablation using high‐intensity focused ultrasound, an incisionless treatment that has been extensively tested in ...

Pathogenic or Likely Pathogenic GRN Variants Are Found in 0.1% of Parkinson's Disease Patients
Movement Disorders, EarlyView.Abstract Background Parkinsonism may be observed in multiple neurodegenerative diseases, including GRN‐associated frontotemporal dementia (FTD‐GRN), complicating the differential diagnosis of Parkinson's disease (PD). Objectives To investigate the presence of GRN variants in a large group of PD patients.

Serum metabolic biomarkers for synucleinopathy conversion in isolated REM sleep behavior disorder
npj Parkinson's Disease, 2021 Isolated rapid eye movement (REM) sleep behavior disorder (iRBD) is a prodromal stage of Lewy-type synucleinopathies (LTS), which can present either with an initial predominant parkinsonism (Parkinson’s disease (PD)) or dementia (dementia with Lewy ...

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.

Pay attention to the basal ganglia: a volumetric study in early dementia with Lewy bodies
Alzheimer’s Research & Therapy, 2019 Background Cortical and subcortical cognitive impairments are usually found in dementia with Lewy bodies (DLB). Roughly, they comprise visuo-constructive/executive function and attention/processing speed impairments, whereas memory would remain ...

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

Early functional changes in lewy body dementia: roles of dynamics, locus coeruleus, and compensation
Alzheimer’s Research & TherapyDementia with Lewy bodies (DLB) is marked by multidomain cognitive impairments, with fluctuations in cognition and alertness being among the most common clinical features. Disruptions in functional connectivity are thought to underlie these fluctuations,

Journal of Neuropsychology, EarlyView.Abstract Apathy is a common neuropsychiatric symptom in Alzheimer's disease (AD) associated with cognitive and functional impairment. Longitudinal studies have examined the associations between apathy and cognition in AD and other dementias, but more information is needed to understand whether the relationships are consistent longitudinally, and ...
