Advances in chronic cerebral circulation insufficiency

Area of Science:

• Neurology
• Vascular Medicine
• Gerontology

Background:

• Chronic cerebral circulation insufficiency (CCCI) represents a persistent state of reduced blood flow to the brain, stemming from diverse underlying causes.
• It is strongly associated with significant neurological outcomes, including ischemic stroke, vascular cognitive impairment, and vascular dementia.
• These conditions contribute substantially to global disability and mortality.

Purpose of the Study:

• To provide a comprehensive overview of the current understanding of CCCI.
• To summarize recent advancements in the epidemiology, pathophysiology, and etiology of CCCI.
• To discuss clinical manifestations, diagnostic approaches, and potential therapeutic strategies for CCCI.

Main Methods:

• This review synthesizes existing literature on chronic cerebral circulation insufficiency.
• It focuses on epidemiological data, experimental research findings, and established pathophysiological mechanisms.
• Clinical, imaging, and etiological aspects are analyzed, alongside therapeutic interventions and future research directions.

Main Results:

• CCCI is characterized by long-term cerebral blood flow reduction with multifactorial origins.
• It is a critical precursor and contributor to ischemic stroke, cognitive decline, and dementia.
• Current understanding encompasses its epidemiology, pathophysiology, clinical presentation, and diagnostic tools.

Conclusions:

• CCCI is a significant clinical state, not merely an independent disease, impacting brain health globally.
• Effective management requires understanding its diverse etiologies and associated risks like stroke and dementia.
• Further research is needed to refine diagnostic criteria and develop targeted therapeutic regimens.
