Sequence of decline on the NIH-toolbox cognitive battery in a predominantly Latino sample with autosomal dominant Alzheimer's disease.

Background: Understanding the sequential progression of cognitive decline in autosomal dominant Alzheimer's disease (ADAD) in the Latino population is crucial for enhancing early identification for targeted interventions. Given the tablet-based administration and increasing frequency of use in epidemiological research, validating this progression within the NIH Toolbox cognitive battery (NIHTB-CB) is important.

Objective: The first aim was to utilize an innovative Event-Based Modeling (EBM) analytic approach to estimate the sequence of cognitive declines in persons at risk for ADAD enriched for being of Latino origin.

Motor abilities and cognitive performance in Latinos with autosomal dominant Alzheimer's disease.

Background: Declining motor abilities might be a noninvasive biomarker for Alzheimer's disease (AD). Studying motor ability and AD progression in younger Latinos with autosomal dominant Alzheimer's disease (ADAD) can provide insights into the interplay between motor ability and cognition in individuals with minimal confounding from age-normative changes and comorbid medical conditions.

Objectives: This study aimed to (1) examine motor abilities as a function of years to dementia diagnosis and (2) examine associations between motor ability and cognitive performance.

The Association between Exposure to Fine Particulate Matter and MRI-Assessed Locus Coeruleus Integrity in the Vietnam Era Twin Study of Aging (VETSA).

Background: Increased exposure to ambient air pollution, especially fine particulate matter () is associated with poorer brain health and increased risk for Alzheimer's disease (AD) and related dementias. The locus coeruleus (LC), located in the brainstem, is one of the earliest regions affected by tau pathology seen in AD. Its diffuse projections throughout the brain include afferents to olfactory areas that are hypothesized conduits of cerebral particle deposition.

Data-driven sequence of cognitive decline in people with Parkinson's disease.

Background: Understanding the sequential progression of cognitive impairments in Parkinson's disease (PD) is crucial for elucidating neuropathological underpinnings, refining the assessment of PD-related cognitive decline stages and enhancing early identification for targeted interventions. The first aim of this study was to use an innovative event-based modeling (EBM) analytic approach to estimate the sequence of cognitive declines in PD. The second aim was to validate the EBM by examining associations with EBM-derived individual-specific estimates of cognitive decline severity and performance on independent cognitive screening measures.
