Remote Ischemic Conditioning: A Potential Treatment for Chronic Cerebral Hypoperfusion

Area of Science:

• Neuroscience
• Cerebrovascular Medicine
• Pathophysiology

Background:

• Chronic cerebral hypoperfusion (CCH) involves reduced cerebral blood flow (CBF), linked to cerebrovascular diseases and aging.
• CCH causes neuronal damage, amyloid-beta accumulation, blood-brain barrier disruption, and endothelial dysfunction.
• CCH is a significant risk factor for cognitive impairment, including vascular dementia and Alzheimer's disease.

Purpose of the Study:

• To discuss the mechanisms underlying brain hypoperfusion.
• To explore remote ischemic conditioning (RIC) as a potential treatment for CCH.
• To promote the clinical application of RIC for CCH.

Main Methods:

• Review of existing literature on CCH and RIC mechanisms.
• Analysis of pathophysiological pathways in CCH models.
• Evaluation of RIC's therapeutic effects in preclinical and clinical studies.

Main Results:

• RIC increases CBF in CCH models and patients.
• RIC inhibits neuronal apoptosis, reduces amyloid-beta deposition, and protects blood-brain barrier integrity.
• RIC alleviates neuroinflammation and improves cognitive deficits, demonstrating neuroprotective effects.

Conclusions:

• RIC is a safe and effective therapeutic strategy for CCH.
• RIC offers significant neuroprotection by addressing multiple pathological aspects of CCH.
• Further research and clinical translation of RIC for CCH are warranted.
