A migraine is an intense headache that can cause severe throbbing pain or a pulsing sensation, usually on one side of the head. It is often accompanied by nausea, vomiting and extreme sensitivity to light and sound. Migraine attacks can last for hours to days, and the pain can be so severe that it interferes with daily activities.
For some, a warning symptom known as an aura occurs before or with the headache. An aura can include visual disturbances, such as flashes of light or blind spots, or other disturbances, such as tingling on one side of the face or in an arm or leg and difficulty speaking.
Migraines can progress through four stages: prodrome, aura, attack and post-drome. Not everyone who has migraines experiences all stages.
- Prodrome – subtle changes that occur one to two days before a migraine.
- Mood changes

Symptoms should be discussed with a primary care physician first to diagnose migraines and prescribe treatment. In serious cases, a primary care physician can refer patients to a neurologist to diagnose migraines and conduct a physical and neurological examination. Tests can include magnetic resonance imaging (MRI) and computerized tomography (CT or CAT) scan.
Individualized treatment options depend on the frequency and severity of migraines and the symptoms associated with migraines. Pain-relieving medications can be taken during migraine attacks to stop symptoms. Preventative medications can be taken regularly to reduce the severity or frequency of migraines.
