Cross‐ancestry polygenic risk scores enhance Alzheimer's disease risk prediction in multiethnic cohorts

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Genome‐wide association studies (GWAS) have identified 80+ genetic loci associated with Alzheimer's disease (AD), enabling the development of polygenic risk scores (PRS). However, the predictive accuracy of PRS in diverse populations remains low.

Linear Active Disturbance Rejection Control for Processes With Time Delays: IMC Interpretation

IEEE Access, 2020
This paper investigates linear active disturbance rejection control (ADRC) for processes with time delay. In the past years several modified active disturbance rejection control methods, including Smith predictor based ADRC (SP-ADRC), predictor observer ...

Classification of tau status with machine learning models in amyloid‐positive cohorts

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Although tau positron emission tomography (PET) imaging is effective for staging tau pathology, it is limited clinically by cost and availability. Machine learning models based on magnetic resonance imaging (MRI)– and amyloid PET–derived features may serve as useful screening tools for tau pathology.

Characterization of [18F]SMBT‐1 binding substrates in Alzheimer's disease and related disorders: A postmortem biochemical and immunohistochemical study

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Neuroimaging studies report associations of amyloid beta (Aβ) positron emission tomography (PET) with [18F](S)‐(2‐methylpyrid‐5‐yl)‐6‐[(3‐fluoro‐2‐hydroxy)propoxy]quinoline ([18F]SMBT‐1), a novel reactive astrogliosis surrogate radiotracer with high affinity for monoamine oxidase B (MAO‐B) in Alzheimer's disease (AD).

Engagement of understudied populations as community change: The South Texas ADRC model

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract Many populations experiencing the highest burdens of Alzheimer's disease and related dementias remain understudied, in part because traditional recruitment and retention models are insufficient to support sustained engagement. The Outreach, Recruitment, and Engagement Core (OREC) of the South Texas Alzheimer's Disease Research Center ...

The role of vascular risk factors in white matter tract microstructure: a multi‐cohort study in older adults

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Vascular risk factors (VRFs) contribute to white matter microstructural degeneration, but their tract‐specific contributions are unclear. We assessed the independent associations of four major VRFs with white matter microstructure in a large, multi‐cohort study.

Stratification by a polygenic risk score of common variation aids in Alzheimer's disease rare variant discovery

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION We utilized an Alzheimer's disease (AD) polygenic risk score (PRS) to discover associations with novel rare variants (RVs). METHODS PRSs for European ancestry (EA) participants of the Alzheimer's Disease Sequencing Project were calculated using summary statistics from a large genome‐wide association study.
