Diagnosing migraine

Migraine is considered a diagnosis of exclusion. That means in order to diagnose migraine, other possible causes of the symptoms must be ruled out or excluded.

Migraine diagnosis typically centers around a description of the different migraine symptoms, how long they occur and how long they last. That’s why it’s key to keep a record of your symptoms—their intensity and frequency—in your migraine symptoms journal. This will help your migraine specialist determine what tests to run to rule out other reasons for your discomfort.
