A migraine headache causes symptoms such as severe head pain and sensitivity to light, sound, or smells. In order to be diagnosed with migraines, your doctor may prescribe tests such as blood tests, imaging tests (X-rays, computerized tomography [CT] scan, magnetic resonance imaging [MRI] scan), or lumbar puncture.

A migraine headache is a neurological condition in which patients experience severe head pain along with sensitivity to light, sound, or smells. It is not the same as a “regular” headache and it is treated differently.

Doctors diagnose migraine headaches based on a patient’s medical history and the description of symptoms. A physical examination may be done but usually it will not find anything out of the ordinary. A neurological examination is often performed to help rule out other causes of the symptoms.

Additional tests may also be used to help rule out other causes for the symptoms such as:
