 Cerebral Vasospasm (CVS) is characterized by the narrowing of blood vessels in the brain, resulting in decreased blood flow and subsequent brain tissue damage. The Circle of Willis, located at the base of the brain and connecting its major arteries, is frequently affected. This condition commonly arises following a subarachnoid hemorrhage, which occurs when an aneurysm ruptures, leading to bleeding around the brain. CVS affects approximately 75% of individuals who survive such hemorrhages, although only about 30% experience symptomatic cognitive deficits. Intracranial arterial constriction typically emerges several days after an aneurysm rupture and persists for 2 to 3 weeks. Our research has shown that symptomatic vasospasm is linked to diminished cognitive function and reduced quality of life, though not necessarily to death or severe disability. Delayed cerebral ischemia (DCI) appears to be the most comprehensive and clinically relevant definition for capturing the adverse cons...
