A consensus or society position rather than new primary data.
This is a narrative review of animal models used to study multi-infarct dementia, comparing embolic, chronic hypoperfusion, hypertensive, and large animal approaches. The authors conclude that current models incompletely recapitulate human MID complexity and that multifactorial, integrative designs are needed to improve translational success.
Narrative review. Multi-infarct dementia in humans; animal models across species examined in review..
MID is the second leading cause of dementia worldwide, characterized by recurrent vascular insults and stepwise cognitive decline No single animal model fully captures human disease complexity Key model limitations include poor replication of infarct heterogeneity, absence of comorbidities, and documented translational failures

This review guides researchers and clinicians on the strengths and limitations of available preclinical MID models, highlighting the need for more integrated paradigms combining multiple pathological hits and comorbidities to better predict clinical trial outcomes.
A systematic review synthesizing methodological approaches and limitations of animal models for multi-infarct dementia, providing guidance on model selection and design rather than reporting novel experimental evidence.

Multi-infarct dementia (MID) is a major subtype of vascular cognitive impairment, second only to Alzheimer's disease as a leading cause of dementia worldwide. Unlike neurodegenerative dementias, MID results from recurrent vascular insults, producing stepwise cognitive decline. Animal models have become indispensable for understanding MID mechanisms and testing therapies, yet no single model fully captures human disease complexity. This review synthesizes current knowledge of embolic, chronic cerebral hypoperfusion, hypertensive, and large animal models of MID. We compare methodological strategies, neuropathological features (including white matter injury, neuroinflammation, and blood-brain barrier disruption), and behavioral outcomes. Key limitations include poor replication of infarct heterogeneity, absence of comorbidities, and translational failures. Emerging directions such as multi-hit paradigms and mixed dementia models are discussed. We conclude that integrative, multifactorial models are essential for improving translational relevance and developing effective therapies.
