Subclinical reductions in cardiac output relate to cognitive decline. We examined the relationship between cardiac output and cerebrospinal fluid (CSF) biomarkers of Alzheimer's disease pathologies in 153 participants from the Vanderbilt Memory and Aging Project. Linear regression and linear mixed effects regression mo...

Medical computer vision presents unique challenges compared to natural images, largely due to the high dimensionality of the data (e.g., 3D and 4D imaging) and limited training samples. Certain medical imaging modalities, such as Diffusion-weighted Magnetic Resonance Imaging (dMRI) - a critical tool for examining brain...

Incomplete field-of-view (FOV) diffusion MRI (dMRI) acquisitions compromise whole-brain white matter analysis by excluding brain regions from tractography and connectivity studies. While deep generative models for dMRI FOV extension have been proposed, their generalizability remains limited by the acquisition-dependent...

This study developed an iPSC line harboring doxycycline-inducible mutant MAPT, which encodes the microtubule-associated protein tau that is implicated in tauopathies, and developed an approach for controlling the initiation and progression of proteinopathy-like pathology in neural organoid systems.

Abstract. Purpose Normative modeling of quantitative brain measurements is being widely adopted as a promising method for charting population-level developmental trajectories and identifying abnormalities in groups and individuals. Generalized additive models for location, scale, and shape (GAMLSS) are a statistical fr...

INTRODUCTION Alzheimer’s disease (AD) disproportionately affects women, but the underlying mechanisms are not fully understood. We compare sex-specific molecular changes across AD with and without dementia at single-cell resolution. METHODS We performed sex-stratified single-nucleus transcriptomic analysis of human AD...
An APOE-independent polygenic risk score for Alzheimer’s disease derived from multiancestry GWAS summary statistics shows consistent associations with cognitive, imaging, biomarker and neuropathological features in diverse populations.

A single-nucleus transcriptomic atlas spanning the human lifespan is used to show that the dorsolateral prefrontal cortex exhibits non-linear, cell-type-specific transcriptional trajectories characterized by dynamic remodelling during development, relative stability in midlife and selective molecular reactivation in la...

A population-scale single-cell transcriptomic atlas of the human dorsolateral prefrontal cortex provides a perspective of the transcriptomic landscape in neurodegenerative and neuropsychiatric disorders, and offers potential targets for therapeutic intervention.

GenFAR, a modular deep learning framework that learns general, clinically informed features from brain MRIs, is introduced, showing that using the learned feature representation can substantially increase the sample efficiency of secondary deep learning training tasks and models, as well as improve their accuracy.

High-dimensional, multimodal predictors and partially observed multivariate outcomes are common in psychometric research. However, existing regularization methods often do not accommodate hierarchical predictor structures and are primarily designed for univariate outcomes. We propose SHIM, a Bayesian framework for stru...
