Cerebral artery spasm is a condition in which the walls of the arteries supplying the brain are irritated by various causes, causing vasospasm and reducing cerebral blood flow. Simple cerebral vasospasm is an abnormal constriction of the cerebral arteries over a period of time, which can lead to headache, dizziness, tinnitus, transient blindness, speech disorders, distorted eyes and mouth, numbness or mobility impairment of one limb, etc. If the spasm is short-lived, the symptoms are mild, or there are no obvious symptoms. Simple cerebrovascular spasm is a functional disease, which generally occurs in young people, especially in the case of irregular life, tension, and increased stress, and the symptoms are relatively mild. Most patients have good self-regulation ability and can be cured after treatment and relaxation. Severe cases can be treated with appropriate relaxation, avoiding strain, and adequate rest, and can also be treated with oral calcium antagonists such as flunarizine and nimodipine. If cerebral vasospasm is combined with intracranial aneurysm, or cerebral arteriosclerosis, hypertension and other diseases, it can easily lead to cerebral hemorrhage, secondary to subarachnoid hemorrhage or hypertensive vasospasm, if not treated in time, paralysis or other neurological symptoms or even life-threatening, and should be treated in time at a specialized hospital. Therefore, most cerebral vasospasms are functional diseases that do not require special treatment, but we should be alert to vasospasms caused by organic lesions such as severe hypertension, cerebral hemangioma, and vascular malformation, etc. Regardless of which lesion is present, we should seek help from hospitals for regular diagnosis and treatment to avoid delayed treatment and serious consequences.
