Basic Science and Pathogenesis.

Background: Age, sex, and APOE genotype are well-established risk factors for late-onset Alzheimer's Disease (LOAD). Previous findings demonstrate that neuroinflammatory profiles of the human midlife female brain closely resemble the human AD brain. Given APOE's role in LOAD pathogenesis, here we investigate the contribution of this risk factor on targeted AD relevant transcriptional pathways.

Basic Science and Pathogenesis.

Background: APP duplications are a rare form of familial Alzheimer's disease (AD). Research has shown variability in clinical presentation with full duplications. There is limited information on those with partial duplications, especially in underrepresented minorities.

Clinical Manifestations.

Background: Hispanic adults comprise 19% of the US population, yet <8% of Alzheimer's Disease and Related Dementia (ADRD) research cohorts. Hispanic adults in the US are 1.5 times more likely to develop ADRDs compared to Non-Hispanics.

Rates and Predictors of Performance Validity Test Failure in Adults Treated for Post-COVID-19 Condition: a Brief Report.

>objective: Cognitive dysfunction is a common symptom of post-COVID-19 condition (PCC). Few studies have examined rates and predictors of cognitive performance validity test (PVT) failure in patients seeking treatment for PCC.

>methods: We report the rates of PVT failure in 323 patients who received care in a long-COVID-19 clinic for any post-COVID-19 health concern and underwent routine telephone cognitive testing that included two embedded PVTs.

Unraveling the clinical-pathological correlations of subjects with isolated and mixed neurodegenerative processes in the National Alzheimer's Coordinating Center dataset.

Although Alzheimer disease neuropathologic change (ADNC) is the most common pathology underlying clinical dementia, the presence of multiple comorbid neuropathologies is increasingly being recognized as a major contributor to the worldwide dementia burden. We analyzed 1051 subjects with specific combinations of isolated and mixed pathologies and conducted multivariate logistic regression analysis on a cohort of 4624 cases with mixed pathologies to systematically explore the independent cognitive contributions of each pathology. Alzheimer disease neuropathologic change and limbic-predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) were both associated with a primary clinical diagnosis of Alzheimer disease (AD) and were characterized by an amnestic dementia phenotype, while only ADNC associated with logopenic variant primary progressive aphasia (PPA).
