The overlap between vascular disease and Alzheimer’s disease - lessons from pathology
Open accessAbstract
Recent epidemiological and clinico-pathological data indicate considerable overlap between cerebrovascular disease (CVD) and Alzheimer's disease (AD) and suggest additive or synergistic effects of both pathologies on cognitive decline. The most frequent vascular pathologies in the aging brain and in AD are cerebral amyloid angiopathy and small vessel disease. Up to 84% of aged subjects show morphological substrates of CVD in addition to AD pathology. AD brains with minor CVD, similar to pure vascular dementia, show subcortical vascular lesions in about two-thirds, while in mixed type dementia (AD plus vascular dementia), multiple larger infarcts are more frequent. Small infarcts in patients with full-blown AD have no impact on cognitive decline but are overwhelmed by the severity of Alzheimer pathology, while in early stages of AD, cerebrovascular lesions may influence and promote cognitive impairment, lowering the threshold for clinically overt dementia. Further studies are warranted to elucidate the many hitherto unanswered questions regarding the overlap between CVD and AD as well as the impact of both CVD and AD pathologies on the development and progression of dementia.
Overview

Written from the paper’s full text.
TL;DR
This review synthesizes pathological and clinicopathological evidence that cerebrovascular disease (CVD) and Alzheimer’s disease (AD) frequently overlap, with additive or synergistic effects on cognitive decline. It emphasizes that vascular lesions may lower the threshold for dementia in early AD, while severe AD pathology often overwhelms the cognitive impact of small vascular lesions.
Key findings
- Up to 84% of aged subjects show morphological substrates of CVD in addition to AD pathology; cerebral amyloid angiopathy (CAA) is present in 82% to 98% of AD patients, and small vessel disease (SVD) is common in both aging and AD.
- In pure vascular dementia (VaD), about 68% of cases show lacunar/strategic subcortical infarcts and 32.5% show multiple large cortico-subcortical infarcts; in mixed dementia (AD + severe CVD), 56.6% show multiple large/lobar or cortico-subcortical lesions and 43.4% show small subcortical lacunar, micro-infarcts, or strategic infarcts.
- Small infarcts in full-blown AD have no impact on cognitive decline and are overwhelmed by Alzheimer pathology, whereas in early AD, cerebrovascular lesions may promote cognitive impairment and lower the threshold for clinically overt dementia.
- Converging autopsy, amyloid PET, functional MRI, and CSF biomarker evidence indicates that AD and CVD exert additive rather than interactive adverse effects on cognitive health, though interactions between vascular factors and amyloidosis/tauopathy remain unresolved.
Methods
- Narrative review of epidemiological, clinico-pathological, and autopsy studies on the overlap between CVD and AD, including data from large cohorts such as the National Alzheimer’s Coordinating Center (NACC) database and the Rush Memory and Aging Project/Religious Orders Study.
- The paper summarizes prevalence and topographical distribution of cerebrovascular lesions across AD, VaD, mixed dementia, and aged controls, using tables from prior autopsy series (e.g., VaD total 188; mixed dementia n = 83; NACC 5,715 autopsy cases).
- Main analysis is qualitative synthesis of reported frequencies, odds ratios, and clinicopathological correlations; no new primary data or systematic meta-analysis are presented.
Limitations
- The paper states that further studies are warranted to elucidate unanswered questions about CVD–AD overlap and that there is still a lack of consensus on incorporating vascular disease into clinical and neuropathological classification schemes for dementias.
- It notes that sample selection may strongly bias results: community samples tend to show greater cerebrovascular pathology than hospital-based samples, and mixed AD/CVD prevalence was higher in the community-based RUSH Memory and Aging Project (44%) than in the RUSH Religious Order Study (28%).
- The text also raises doubts about PiB-PET as representative of Aβ loads in the living brain and states that differentiation of mixed AD/CVD with CSF biomarkers may be difficult; evident from the text, this is a narrative review without a systematic search or quantitative pooling, so findings depend on heterogeneous autopsy cohorts and diagnostic criteria.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
