ABSTRACT Background Vascular dementia (VaD) includes a group of brain disorders that are characterized by cerebrovascular pathology.Neuroinflammation, disruption the blood–brain barrier (BBB) permeability, white matter lesions, and neuronal loss all significant pathological manifestations VaD play key role in disease progression. Necroptosis, also known asprogrammed necrosis, is mode programmed cell death distinct from apoptosis closely associated with ischemic injury neurodegenerative diseases. Recent studies have shown necroptosis exacerbates BBB destruction, activates neuroinflammation, promotes loss, severely affects prognosis. Results Conclusions In this review, we outline roles its molecular mechanisms process VaD, particular focus on modulating neuroinflammation exacerbating permeability elaborate regulatory centrally involved cells mediated tumor necrosis factor‐α VaD. We analyze possibility specific strategy targeting would help inhibit destruction With necroptosis, study delved into impact changes prognosis to provide new treatment ideas.

Vascular dementia (VD) is a prevalent cognitive disorder among the elderly. Its pathological mechanism encompasses neuronal damage, synaptic dysfunction, vascular abnormalities, neuroinflammation, and oxidative stress, others. In recent years, extracellular vesicles (EVs) derived from mesenchymal stem cells (MSCs) have garnered significant attention as an emerging therapeutic strategy. Current research indicates that MSC-derived (MSC-EVs) play pivotal role in both diagnosis treatment of VD. Thus, this article delves into advancements MSC-EVs VD, discussing mechanisms by which EVs influence pathophysiological processes These form theoretical foundation for their neuroprotective effect VD treatment. Additionally, highlights potential applications diagnosis. conclusion, present promising innovative strategy With rigorous ongoing innovation, concept can transition practical clinical treatment, providing more effective options patients.

There evidence supporting hypothesis that inflammatory immune mechanisms involved Microglia, resident macrophage tissues central nervous system, play significant role neuroinflammation an important amyloid-β clearance brain, impaired microglial has also been shown be pathogenesis disease. However, abundant microglia have harmful actions Once activated, they can mediate uptake at neuronal synapses. They exacerbate tau pathology secrete deleterious factors directly or indirectly damage neurons. Thus, depending on stage disease, act both protectively detrimentally. Therefore, it still necessary continue with studies better understand Currently available drugs only improve cognitive symptoms, no impact progression not curative, so identifying studying new therapeutic approaches important.
