Amyloid imaging in aging and dementia: testing the amyloid hypothesis in vivo. [PDF]

, 2009
Amyloid imaging represents a major advance in neuroscience, enabling the detection and quantification of pathologic protein aggregations in the brain. In this review we survey current amyloid imaging techniques, focusing on positron emission tomography ...

Improving the identification of dementia with Lewy bodies in the context of an Alzheimer’s-type dementia

Alzheimer’s Research & Therapy, 2018
Background Dementia due to Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB) are the two most common neurodegenerative causes of dementia. They commonly occur together, especially in older people, but clinical identification of these diseases ...

Genetic and Pathological Testing Attitudes for Parkinson's Disease in At‐Risk Relatives

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's disease (PD) is increasingly recognized as a neurodegenerative disorder with a broad clinical spectrum and diverse biomarkers enabling early detection. α‐synuclein seed amplification assays (SAA) and genetic testing now allow identification of PD pathology in asymptomatic individuals.

cAMP-Inhibits Cytoplasmic Phospholipase A(2) and Protects Neurons against Amyloid-beta-Induced Synapse Damage [PDF]

, 2015
A key event in Alzheimer’s disease (AD) is the production of amyloid-β (Aβ) peptides and the loss of synapses. In cultured neurons Aβ triggered synapse damage as measured by the loss of synaptic proteins. α-synuclein (αSN), aggregates of which accumulate

Alzheimer'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.

Cognitive fluctuations in connection to disgraphia a comparison of Alzheimer's disease with dementia Lewy bodies [PDF]

, 2015
Background: The purpose of the present study was to examine the relationship between cognitive impairment and the performance of handwritten scripts presented as “letter-writing” to a close relative by patients with dementia Lewy bodies (DLB), as ...

Exocrine Gland Dysfunction in Parkinson's Disease: Pathophysiology, Clinical Manifestations, and Therapeutic Perspectives—A Narrative Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Non‐motor symptoms, especially autonomic dysfunction, are major contributors to disability and decreased quality of life in Parkinson's disease (PD). Despite being common and having a wide range of clinical facets, exocrine gland dysfunction is still not well recognized and managed.

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 ...
