. 2025 Jan;
21(2):e14500.
PMID: 39888320
Introduction: This study investigates the inter-related roles of hippocampal neuronal loss (HNL), limbic-predominant age-related TAR-DNA binding protein of 43 kDa (TDP-43) encephalopathy neuropathologic changes (LATE-NC), and Alzheimer's disease neuropathologic changes...

PMID: 39606348
Background: This study investigates associations between diet patterns and the risk of intracranial atherosclerosis (ICAD) in individuals with preexisting hypertension (HTN) or myocardial infarction (MI). Method: 676 autopsied participants (mean...

. 2024 Feb;
83(3):181-193.
PMID: 38300796
This study examined the frequency of chronic traumatic encephalopathy-neuropathologic change (CTE-NC) and aging-related tau astrogliopathy (ARTAG) in community-dwelling older adults and tested the hypothesis that these tau pathologies are associated...

. 2023 Oct;
96(2):563-578.
PMID: 37840485
Background: Assessments of Alzheimer's disease pathology do not routinely include lower brainstem, olfactory bulb, and spinal cord. Objective: Test if amyloid-β (Aβ) and paired helical filament (PHF) tau-tangles outside the...

Alzheimers Dement
. 2023 Jun;
19(9):4150-4162.
