Greater locus coeruleus vulnerability in atypical clinicopathologic forms of Alzheimer's disease. [PDF]

Alzheimers Dement
Abstract INTRODUCTION The locus coeruleus (LC) degenerates early in Alzheimer's disease (AD). However, the extent of rostrocaudal degeneration across clinicopathologic heterogeneity remains underexplored in AD. METHODS Using digital pathology, we quantified LC neuronal density and area at three neuroanatomic levels in a large AD series.

Longitudinal 123I‐FP‐CIT SPECT Analysis Using DaTQUANT Software in Autopsy Confirmed Dementia with Lewy Bodies Patients [PDF]

Alzheimers Dement
Abstract Background Dementia with Lewy Bodies (DLB) has been overlooked or misdiagnosed as Alzheimer's disease (AD) dementia due to its frequent concomitant AD pathology with Lewy Body Disease (LBD) pathology. Although autopsy confirmation has been the gold standard for the precise diagnosis of DLB, time‐course 123I‐FP‐CIT SPECT (DaT‐SPECT) findings in

Association between visual hallucinations and α-synuclein oligomers in patients with dementia with Lewy bodies. [PDF]

Alzheimers Dement
Abstract INTRODUCTION Visual hallucinations (VHs) represent one of the core clinical features of dementia with Lewy bodies (DLB); however, their underlying pathology remains unclear. METHODS We employed proximity ligation assay (PLA) and phosphorylated α‐synuclein (αSYN) immunohistochemistry to compare αSYN oligomers and Lewy‐related pathology across ...

Association between Human Leukocyte Antigen Alleles and Neuropathological Outcomes in Lewy Body Disease. [PDF]

Ann Neurol
Objective Lewy body disease (LBD) is a complex neurodegenerative disorder characterized by the accumulation of misfolded α‐synuclein in the brain. Neuroinflammation has long been implicated in LBD pathogenesis, and recent genetic studies in Parkinson's disease (a clinical manifestation of LBD) have shown consistent association with the human leukocyte ...

Imperfect Synthetic Controls. [PDF]

J Appl Econ (Chichester Engl)
ABSTRACT The synthetic control method assumes the existence of a perfect synthetic control, which cannot exist if the outcomes are functions of transitory shocks with nonzero asymptotic variance and may not exist even in expectation for the treated unit. This paper first shows the benefits of estimating synthetic controls for all units.

No childhood advantage in the acquisition of skill in using an artificial language rule. [PDF]

PLoS ONE, 2010
A leading notion is that language skill acquisition declines between childhood and adulthood. While several lines of evidence indicate that declarative ("what", explicit) memory undergoes maturation, it is commonly assumed that procedural ("how-to ...

NODDI reveals white matter microstructural changes in isolated REM sleep behavior disorder [PDF]

Alzheimers Dement
Abstract Background Isolated REM sleep behavior disorder (iRBD) is a parasomnia that reflects an evolving α‐synucleinopathy disorder, providing an opportunity to study early pathological changes. While diffusion tensor imaging (DTI) studies have shown white matter changes in iRBD, Neurite Orientation Dispersion and Density Imaging (NODDI) may offer ...

Substantia Nigra Iron Deposition in Lewy Body Disease: A Magnetic Resonance Imaging and Neuropathology Study. [PDF]

Mov Disord
Abstract Objective To compare iron deposition in the substantia nigra (SN) as measured with quantitative susceptibility mapping (QSM) on antemortem magnetic resonance imaging (MRI) between individuals with and without Lewy‐related pathology at autopsy. Methods We performed a retrospective cohort study including 54 participants who underwent autopsy and
