Clinical symptoms of headache can be diagnosed by CT and other imaging tests, blood pressure tests, blood and cerebrospinal fluid tests, etc., and it is recommended to consult a doctor in time. 1. Imaging examination: clinically, for those who have headache, head CT, magnetic resonance imaging (MRI) and head angiography (CTA) can be performed to clarify whether there is intracranial hemorrhage, obstruction, or space-occupying lesions, etc., and for those who have cervical vertebrae discomfort, cervical vertebrae MRI can be performed to clarify the diagnosis. 2. Blood pressure examination: For patients with a history of hypertension, hyperlipidemia, etc., further blood pressure examination is needed to exclude headache caused by high blood pressure. 3. Blood and cerebrospinal fluid examination: For patients with unclear etiology, blood and cerebrospinal fluid examination is also needed to clarify whether there are infections and other causes of headache. Headache patients are recommended to consult a doctor in time, and choose the appropriate tests under the doctor’s advice to clarify the diagnosis, which will help to carry out the treatment.
