Bayesian modeling of item heterogeneity in dichotomous recognition memory data and prospects for computerized adaptive testing

open access: yesScientific Reports, 2022
Most current models of recognition memory fail to separately model item and person heterogeneity which makes it difficult to assess ability at the latent construct level and prevents the administration of adaptive tests.

Caudo‐rostral brain spreading of α‐synuclein through vagal connections

open access: yesEMBO Molecular Medicine, 2013
α‐Synuclein accumulation and pathology in Parkinson's disease typically display a caudo‐rostral pattern of progression, involving neuronal nuclei in the medulla oblongata at the earliest stages.

TALKING TIME: A pilot randomized controlled trial investigating social support for informal caregivers via the telephone

open access: yesBMC Health Services Research, 2020
Background Caring for people with dementia at home requires considerable time, organization and commitment. Therefore, informal caregivers of people with dementia are often overburdened. This study examined the effects of the telephone-based Talking Time

Glucocerebrosidase is imported into mitochondria and preserves complex I integrity and energy metabolism

open access: yesNature Communications, 2023
GBA1 mutations cause Gaucher’s disease and are the strongest risk factor for Parkinson’s disease. Using stable cell lines and patient iPSCs, the authors show mitochondrial localization of GBA1, which may affect neurodegenerative disease risk.

FRET-based Tau seeding assay does not represent prion-like templated assembly of Tau filaments

open access: yesMolecular Neurodegeneration, 2020
Tau aggregation into amyloid fibers based on the cross-beta structure is a hallmark of several Tauopathies, including Alzheimer Disease (AD). Trans-cellular propagation of Tau with pathological conformation has been suggested as a key disease mechanism ...

Exploring the ATN classification system using brain morphology

open access: yesAlzheimer’s Research & Therapy, 2023
Background The NIA-AA proposed amyloid-tau-neurodegeneration (ATN) as a classification system for AD biomarkers. The amyloid cascade hypothesis (ACH) implies a sequence across ATN groups that patients might undergo during transition from healthy towards ...

Improving 3D convolutional neural network comprehensibility via interactive visualization of relevance maps: evaluation in Alzheimer’s disease

open access: yesAlzheimer’s Research & Therapy, 2021
Background Although convolutional neural networks (CNNs) achieve high diagnostic accuracy for detecting Alzheimer’s disease (AD) dementia based on magnetic resonance imaging (MRI) scans, they are not yet applied in clinical routine.

The economic burden of subjective cognitive decline, mild cognitive impairment and Alzheimer's dementia: excess costs and associated clinical and risk factors

open access: yesAlzheimer’s Research & Therapy
Background With the availability of first disease-modifying treatments, evidence on costs across the entire Alzheimer's Continuum, especially for early disease stages, becomes increasingly important to inform healthcare planning, resource allocation, and

Anti-aggregant tau mutant promotes neurogenesis

open access: yesMolecular Neurodegeneration, 2017
Background The microtubule-associated protein Tau plays a role in neurodegeneration as well as neurogenesis. Previous work has shown that the expression of the pro-aggregant mutant Tau repeat domain causes strong aggregation and pronounced neuronal loss ...

Dysfunction of the episodic memory network in the Alzheimer’s disease cascade

open access: yesNature Communications
Alzheimer’s disease (AD) is a major cause of dementia and cognitive decline. Here, we assessed how episodic memory (EM) network dysfunction, a hallmark of AD, is related to the longitudinal progression of AD biomarkers, neurodegeneration and cognition ...
