Vascular headache may be caused by head vasoconstriction-diastolic dysfunction, hypertension, intracranial organic lesions and other reasons. 1. Head vasoconstriction-diastolic dysfunction: when head vasoconstriction-diastolic dysfunction is caused by environmental and psychological factors, taking medication, etc., the patient will have throbbing pain on one side of the head or on both sides of the head, which manifests itself as distension, nausea, vomiting and other symptoms. 2. Hypertension: vascular headache caused by hypertension usually manifests as bilateral swelling and pain in the top of the head, fronto-temporal area, soreness, etc. Vascular throbbing headache may also occur. 3. Intracranial organic lesions: Cerebral infarction, intracranial hemorrhage and other intracranial organic lesions lead to ischemia of brain tissue and formation of hematoma outside the dura mater, which can induce vascular headache. Patients may have headache, dizziness, nausea, vomiting, numbness of one side of the limbs or even hemiplegia and other symptoms. It is recommended that patients with vascular headache should seek medical treatment in time to complete the relevant examinations and make a clear diagnosis for targeted treatment.
