Overview

Migraine is a recurrent headache disorder with intense pain. Many patients can identify triggers that cause or aggravate the headache. Usual triggers include certain food, anxiety and stress, changes in the weather, l ack of sleep or too much sleep and sensory stimuli. Hormonal changes may induce pain for some female patients. Headache caused by migraine is ususally described as moderate to severe, intense, throbbing or pounding pain which may be confined to one side or may affect both sides of the head. Other symptoms include nausea with or without vomiting, sensitivity to light and sound. Typical trigger and symptoms with a family history of migraines may help the doctor diagnose migraine. For atypical patients, the doctor may order head images to rule out other possible causes of headache. Pain relievers including NSAIDS and acetaminophen may help relieve pain and reduce frenquency. Many patients with migraine can relieve pain and reduce frenquency with treatments.

Diagnosis

• Head images such CT and MRI are needed to rule out other possible causes of headache.
• Lumbar puncture: When your headache is suspected meningitis, the doctor may order this test. During this procedure, the patient lies on the side, with knees pulled up toward the chest, and chin tucked downward. After injecting the anesthetic into the lower spine, the doctor insert a spinal needle into the lower back area to measure CSF pressure and collect a sample. The patient is often asked to lie down for a while after the process.
