Cerebral vasospasm, a condition where the blood vessels in the brain constrict and reduce blood flow, can lead to serious neurological complications. Synonyms for this condition include cerebral artery vasospasm, brain artery spasm, and intracranial arterial spasm. Another term used to describe cerebral vasospasm is cerebral vasoconstriction syndrome. This may encompass a wider range of symptoms beyond the narrowing of the blood vessels, such as headaches, seizure, and confusion. Other related conditions that may be associated with cerebral vasospasm include subarachnoid hemorrhage, aneurysm, and traumatic brain injury. Accurate diagnosis and treatment of this condition are critical for preventing long-term neurological damage.
