Cerebral Vascular Disease and Neurovascular Injury in Ischemic Stroke

Area of Science:

• Neuroscience
• Vascular Biology
• Neurology

Background:

• Cerebrovascular diseases, encompassing large and small cerebral vessel disease, are leading causes of global mortality and morbidity.
• These conditions contribute significantly to stroke, neurological dysfunction, and degeneration, with hypertension being a primary risk factor.
• Current understanding of neurovascular disease and ischemic injury mechanisms lags behind general neuroprotection and vascular biology.

Purpose of the Study:

• To review key structural and functional vascular changes that lead to hypoperfusion and ischemia.
• To discuss the mechanisms of blood-brain barrier damage during ischemia, including cellular and molecular factors.
• To identify targets for novel therapeutic strategies to mitigate cerebrovascular disease progression and ischemic event impact.

Main Methods:

• Literature review focusing on structural and functional vascular changes in the brain.
• Analysis of cellular and molecular mechanisms affecting blood-brain barrier integrity post-ischemia.
• Synthesis of current knowledge on risk factors, injury, and therapeutic interventions.

Main Results:

• Cerebral small and large vessel diseases are significant contributors to stroke and neurological decline.
• Hypertension is identified as the foremost risk factor driving these vascular pathologies.
• Ischemia-induced blood-brain barrier disruption involves endothelial cells, pericytes, immune cells, and matrix metalloproteinases.

Conclusions:

• Understanding vascular changes and blood-brain barrier alterations in ischemia is critical for advancing treatment.
• Identifying key cellular and molecular pathways offers potential for novel therapeutic approaches.
• Targeting these mechanisms may slow cerebrovascular disease progression and reduce the impact of ischemic events.
