The Migraine Disability Assessment Test (MIDAS) is a test used by doctors to determine how severely migraines affect a patient's life.
Patients are asked questions about the frequency and duration of their headaches, as well as how often these headaches limited their ability to participate in activities at work, at school, or at home.
The test was evaluated by the professional journal Neurology in 2001; it was found to be both reliable and valid.

[3] Once scored, the test gives the patient an idea of how debilitating his/her migraines are based on this scale: 0 to 5, MIDAS Grade I, Little or no disability 6 to 10, MIDAS Grade II, Mild disability 11 to 20, MIDAS Grade III, Moderate disability 21+, MIDAS Grade IV, Severe disability[4]
