The MIDAS questionnaire, otherwise known as the 'Migraine Disability Assessment Questionnaire', is a questionnaire developed to help physicians and patients assess headaches so that the proper treatment can be rendered correctly. It measures disability that is caused by headaches by counting the number of days lost as a result of headaches.

This questionnaire was developed by Professor Richard Lipton of the Albert Einstein College of Medicine in New York and Dr. Walter Steward of the Johns Hopkins School of Public Health in Baltimore. For more information on the MIDAS questionnaire, please visit the MIDAS website.

Please answer the all of the following questions regarding your headaches. After completing the questionnaire, please note the total at the bottom. This total is used to measure the grade of your headaches, as determined by your disability level. Please refer to the legend at the bottom of the table for grade information.
