The diagnosis of migraine is based on the patient’s description of symptoms and a clinical evaluation by the doctor. The diagnosis is usually made based on the patient’s symptoms and medical history, and it can be confirmed by ruling out other possible causes for the symptoms. Typical migraine symptoms include recurrent, severe headaches that may be throbbing and focused on one side of the head. Symptoms may also include nausea, vomiting, and sensitivity to light or sound.
