Atherosclerosis and Dementia
A Cross-Sectional Study With Pathological Analysis of the Carotid Arteries
Background and Purpose—Previous ultrasound-based studies have shown an association between carotid artery atherosclerosis and dementia. Our aim was to investigate this association using postmortem examination.
Methods—Postmortem morphometric measurements of carotid stenosis and intima-media thickness were performed in individuals with dementia (n=112) and control subjects (n=577). Multivariate logistic regression models were applied.
Results—High-grade left internal carotid stenosis (≥70%) was associated with increased odds for dementia (OR, 2.30; 95% CI, 1.14–4.74; P=0.02). Intima-media thickness was not associated with dementia.
Conclusions—The likelihood of dementia is increased with high-grade left internal carotid artery atherosclerosis after adjusting for demographic and cardiovascular risk factors.
