Alzheimers Dement
December 2024
University of Southern California, Los Angeles, CA, USA.
Background: Blood pressure (BP) management is an accessible therapeutic target for dementia prevention. BP variability (BPV) is a newer aspect of BP control recently associated with cognitive decline, dementia and Alzheimer's disease (AD), independent of traditionally targeted mean BP levels. Most of this work has relied on largely non-Hispanic White study samples in observational cohorts.

Method: To investigate the relation of AHT with change in cognitive function and postmortem brain pathology, we evaluated 4,207 older persons without known dementia at enrollment and a subset of 1880 participants who died and came to autopsy.

Alzheimers Dement
December 2024
Institute for Memory Impairments and Neurological Disorders, University of California, Irvine, Irvine, CA, USA.
Background: Participant dropout from study treatment in a clinical trial can leave a trial underpowered, produce bias in statistical analysis, and limit interpretability of study results. Retaining participants in clinical trials for the full study duration is therefore as important as participant recruitment. This analysis aims to identify the baseline characteristics of participants who discontinued during the blinded phase of one of the first and largest preclinical AD trial completed to date, the Anti-Amyloid treatment in Asymptomatic AD (A4) Study.

Alzheimers Dement
December 2024
University of California, Irvine, Irvine, CA, USA.
Background: Recruitment challenges in people with and without Down syndrome (DS) can delay research progress and risk sample bias. This study identified and quantified differences in research attitudes across populations of research enrollment decision-makers for individuals with and without DS.
Method: We compared scores on the Research Attitudes Questionnaire (RAQ) of individuals enrolled in two recruitment registries: the UCI Consent to Contact [C2C (N = 4818)] and DS-Connect (N = 976).

Alzheimers Dement
December 2024
HealthPartners Institute, Minneapolis, MN, USA.
Background: Cholinesterase inhibitors (ChEIs) are cornerstones in the symptomatic treatment of Alzheimer's disease (AD) and dementia with Lewy bodies (DLB) and are also prescribed for vascular dementia (VD). Despite their widespread use, patterns of prescribing ChEIs are not fully understood.
Objective: Examine the prevalence, timing, and types of ChEI prescriptions before and after dementia diagnosis including prescribing patterns by patient sex and race.
