Hypertension may associate with cerebral small vessel disease and infarcts through the pathway of intracranial atherosclerosis.

Hypertension, a major modifiable risk factor for cardiovascular diseases, is linked to late-life neurocognitive disorders such as vascular dementia and Alzheimer's disease (AD). This study explores the associations between hypertension, intracranial atherosclerotic disease (ICAD), cerebral small vessel disease (cSVD), and Alzheimer's disease neuropathologic change (ADNC) in a large community-based autopsy study. This cross-sectional study used data from the Biobank for Aging Studies of the University of São Paulo Medical School.

The Association Between Neuropathological Lesions and Body Mass Index Is Independent of Cognitive Abilities.

Background: The association of moderate and severe dementia with low body mass index (BMI) is well described, but weight decline seems to also occur in individuals with preclinical neuropathologies. Considering that up to one-fifth of individuals with normal cognition meet the criteria for a dementia-related neuropathological diagnosis, autopsy studies are key to detecting preclinical neurodegenerative and cerebrovascular diseases that could be underlying weight changes.

Objective: We investigated the association between dementia-related brain lesions and BMI and evaluated whether the cognitive function was a mediator of this association.

Causes of death in individuals with lifetime major depression: a comprehensive machine learning analysis from a community-based autopsy center.

Background: Depression can be associated with increased mortality and morbidity, but no studies have investigated the specific causes of death based on autopsy reports. Autopsy studies can yield valuable and detailed information on pathological ailments or underreported conditions. This study aimed to compare autopsy-confirmed causes of death (CoD) between individuals diagnosed with major depressive disorder (MDD) and matched controls.
