Migraine headache may be diagnosed by your doctor based on your symptoms, history of migraines in the family, and your response to treatment. Your doctor will take a detailed history to make sure that your headaches are not due to tension, sinus inflammation, or a more serious underlying brain disorder. On physical examination, your doctor is likely to find nothing wrong with you.
Sometimes an MRI or CT scan is obtained to rule out other causes of headache like sinus inflammation or a brain mass. In the case of a complicated migraine, an EEG may be needed to exclude seizures. Rarely, a lumbar puncture (spinal tap) might be performed.
