Cerebrovascular spasm can cause persistent dizziness and, in severe cases, neurological deficits such as inflexibility of limbs, sensory numbness, and clumsy speech.1 If cerebrovascular spasm is not relieved, the patient’s dizziness will persist and, in severe cases, lead to severe headache, nausea, vomiting, and other problems. It is recommended that patients can consult a hospital to improve the examination of the blood vessels in the head, and after clarification, patients can be given symptomatic oral nimodipine, flunarizine hydrochloride, cipro and other drugs to relieve the patient’s vascular spasm and improve the patient’s dizziness. 2. There are many causes of cerebral vascular spasm, which may occur because of the patient’s exertion, cold or poor rest.
