Cerebral blood flow in geriatrics--a review

Area of Science:

• Neurology
• Physiology
• Pathology

Background:

• Cerebral circulation is vital for brain function.
• Ageing, hypertension, cerebral infarction, and dementia significantly impact brain blood flow.

Purpose of the Study:

• To review physiological and pathological changes in cerebral circulation.
• To highlight the relevance of these changes in specific neurological conditions.

Main Methods:

• Literature review of studies on cerebral circulation.
• Analysis of research focusing on ageing, hypertension, stroke, and dementia.

Main Results:

• Identified alterations in cerebral blood flow patterns associated with ageing.
• Documented the effects of hypertension on cerebral circulation and infarction risk.
• Reviewed the link between impaired cerebral circulation and dementia pathogenesis.

Conclusions:

• Cerebral circulation changes are critical in ageing and neurological diseases.
• Further research into cerebral hemodynamics can inform therapeutic strategies for dementia and stroke.
