Questionnaire used to assess the negative impact of headaches on normal daily activates.
6-item survey with the following domains:
Adverse impact of headache and social functioning
Frequency of severe headache pain
The answers for questions are scored from never to always with five alternatives. These are scored from 6 (never) to 13 (always). The higher the patient scores, the greater the migraine impact on life.

MIDAS measures headache-related disability with a 5-item questionnaire
The three domains assessed include:
Everyday activities in work
Everyday activities at home
Answers to domains 1 to 5 are scored by number of days. The number of days from each question are added together to form total number of days. Based on the total days, a MIDAS Grade I-IV is created. Grade I indicates mild or no disability (low number of total days) and Grade IV indicates severe disability (high number of total days).
