Impact of cerebral small vessel disease on cognitive outcomes in early age at onset MCI and dementia: Findings from the DIASPORA study. [PDF]
Abstract BACKGROUND This study assessed the impact of cerebral small vessel disease (CSVD) on cognition in individuals with early‐onset (EO; <65 years) and late‐onset (LO; ≥65 years) cognitive complaints. METHODS Participants underwent prospective evaluations including cognitive testing, hyperphosphorylated tau‐217 (p‐tau217) and neurofilament‐light ...

Alzheimer's disease patients have smaller venous drainage system compared to cognitively healthy controls. [PDF]
Abstract INTRODUCTION One of the pathological hallmarks of Alzheimer's disease (AD) is the accumulation of amyloid beta 42 (Aβ42). Decreased venous drainage may enhance Aβ42 accumulation. We aimed to compare venous cross‐sectional area (CSA) of AD patients to cognitively healthy controls.

Study of brain perfusion in adults with Down syndrome along the Alzheimer's disease continuum. [PDF]
Abstract INTRODUCTION We assessed pseudo‐continuous arterial spin labeling (pCASL) sensitivity to detect changes in cerebral blood flow (CBF) in adults with Down syndrome (DS) along the Alzheimer's disease (AD) continuum and explored the similarity with sporadic AD (sAD) hypoperfusion profile.

Generational effects in Down syndrome: Enriched environment enhances functionality without reducing Alzheimer's disease risk. [PDF]
Abstract INTRODUCTION Down syndrome (DS) is the leading cause of intellectual disability (ID) and a genetic form of Alzheimer's disease (AD). We wanted to assess whether generational changes have induced (1) milder ID with greater independence and (2) delayed AD diagnosis.

Characterization of white matter hyperintensities in Down syndrome. [PDF]
Abstract INTRODUCTION In Down syndrome (DS), white matter hyperintensities (WMHs) are highly prevalent, yet their topography and association with sociodemographic data and Alzheimer's disease (AD) biomarkers remain largely unexplored. METHODS In 261 DS adults and 131 euploid controls, fluid‐attenuated inversion recovery magnetic resonance imaging scans

Alpha-synuclein co-pathology in Down syndrome-associated Alzheimer's disease. [PDF]
Abstract INTRODUCTION Alpha‐synuclein (αSyn) seed amplification assay (SAA) enables in vivo study of αSyn but remains underexplored in Down syndrome‐associated Alzheimer's disease (DSAD). METHODS We analyzed αSyn‐SAA in cerebrospinal fluid (CSF) from 270 adults with Down syndrome, from the Down Alzheimer Barcelona Neuroimaging Initiative and from the ...

Cortical microinfarcts in adults with Down syndrome assessed with 3T-MRI. [PDF]
Abstract BACKGROUND Cortical microinfarcts (CMI) were attributed to cerebrovascular disease and cerebral amyloid angiopathy (CAA). CAA is frequent in Down syndrome (DS) while hypertension is rare, yet no studies have assessed CMI in DS. METHODS We included 195 adults with DS, 63 with symptomatic sporadic Alzheimer's disease (AD), and 106 controls with ...

Basal forebrain atrophy along the Alzheimer's disease continuum in adults with Down syndrome
Abstract Background Basal forebrain (BF) degeneration occurs in Down syndrome (DS)‐associated Alzheimer's disease (AD). However, the dynamics of BF atrophy with age and disease progression, its impact on cognition, and its relationship with AD biomarkers have not been studied in DS. Methods We included 234 adults with DS (150 asymptomatic, 38 prodromal

classecol: Classifiers to understand public opinions of nature
Abstract Human perceptions of nature, once the domain of the social sciences, are now an important part of environmental research. However, the data and tools to tackle this research are lacking or are difficult to apply. Here, we present a collection of text classifier models to identify text relevant to the broad topics of hunting and nature ...
