Vascular dementia Insights and Trends
- Vascular dementia is a common and complex neurocognitive disorder characterized by cognitive decline, executive dysfunction, and impaired reasoning, arising from cerebrovascular pathology and chronic or acute disruptions in cerebral blood flow that damage key neural networks involved in cognition, memory, and behavioral regulation.
- In 2025, the total number of diagnosed prevalent cases of dementia across the 7MM was approximately 17 million.
- In 2025, the total number of diagnosed prevalent cases of vascular dementia across the 7MM was approximately 3 million.
- Diagnosis of vascular dementia remains inconsistent due to variability in clinical criteria, overlap with other dementias (particularly Alzheimer), and reliance on advanced neuroimaging techniques that are not uniformly accessible. Early-stage disease is often underdiagnosed, as subtle cognitive and vascular changes may not be detected in routine clinical settings.
- Patients with vascular dementia frequently experience neuropsychiatric symptoms such as apathy, depression, agitation, and emotional lability, which significantly impact quality of life and caregiver burden.

Vascular dementia Understanding
Vascular dementia Overview and Diagnosis
Vascular dementia is a progressive neurocognitive disorder caused by reduced or impaired blood flow to the brain, leading to a gradual decline in cognitive and functional abilities. It is recognized as the second most common form of dementia after Alzheimer’s disease, particularly among the elderly population. Despite its prevalence, vascular dementia remains underdiagnosed and is often confused with Alzheimer’s disease due to overlapping clinical features; in many cases, both conditions may coexist.
The diagnosis of vascular dementia is typically based on a combination of clinical history, cognitive impairment, and evidence of cerebrovascular disease. A key feature supporting diagnosis is a history of stroke or multiple silent infarcts accompanied by a noticeable decline in cognitive function. The disease often shows a characteristic “stepwise progression”, where sudden declines in cognition occur following vascular events, with periods of relative stability in between. In settings where advanced imaging is not available, clinical history, along with the presence of vascular risk factors and family history, may be sufficient for a probable diagnosis.

Vascular Dementia Epidemiology
Key Findings from Vascular Dementia Epidemiological Analysis and Forecast
- The 7MM accounted for approximately 3 million diagnosed prevalent cases of vascular dementia in 2025, highlighting the substantial and growing burden of vascular cognitive impairment across major global healthcare markets.
- Disease burden increased markedly with age, with individuals aged 81–90 years representing the largest patient group in the 7MM in 2025 (1.4 million cases), followed by those aged =91 years (840,000 cases) and 71–80 years (660,000 cases). This trend underscores the strong association between advancing age and vascular dementia prevalence.
- Across the EU4 and the UK, small vessel disease (SVD) was the leading etiological contributor to vascular dementia in 2025, accounting for approximately 790,000 cases, substantially exceeding large vessel disease (LVD) and mixed etiologies. This finding highlights the dominant role of microvascular pathology in driving the overall disease burden.
Industry Experts and Physician Views for Vascular Dementia
To keep up with vascular dementia dynamic epidemiology trends, we take Key Opinion Leaders (KOLs) and Subject Matter Experts (SMEs) opinions working in the domain through primary research to fill the data gaps and validate our secondary research. Industry Experts were contacted for insights on the vascular dementia epidemiology, including MD, PhD, Instructor, Postdoctoral Researcher, Professor, Researcher, and others.
DelveInsight’s analysts connected with 8+ KOLs to gather insights at country level. Centers such as the University of Santo Tomas, Berlin Institute of Health at Charité, Paris-Est Créteil University, UCL Queen Square Institute of Neurology etc. were contacted.

“Vascular dementia is often identified relatively late in its course, not because the pathology emerges abruptly, but because early clinical manifestations, such as slowed processing speed and subtle executive dysfunction are frequently attributed to normal aging or comorbid conditions, delaying formal diagnosis.” |
|
Italy |
“A substantial proportion of patients diagnosed with Vascular dementia actually have mixed pathology, where vascular lesions coexist with neurodegenerative changes such as Alzheimer’s disease. This overlap complicates diagnosis, as targeting a single mechanism may not yield meaningful clinical benefit.” |
