🩺What is Migraine?
The MIDAS questionnaire was developed by Lipton et al. to measure headache-related disability and guide treatment intensity. It assesses the number of days in the past 3 months that headache impacted work (paid employment or school), household work, and non-work (family, social, leisure) activities. The total score ranges from 0 to 270+, with higher scores indicating greater disability.
📊Clinical Assessment & Risk Scoring
Healthcare professionals use these validated clinical calculators, diagnostic scales, and risk scoring systems to assess the severity, prognosis, or therapeutic dosing requirements for Migraine:
MIDAS — Migraine Disability Assessment Test
The Migraine Disability Assessment (MIDAS) questionnaire quantifies headache-related disability over the past 3 months. It asks 5 questions about days of missed or reduced activity in work, household work, and family/social/leisure activities. The total score stratifies patients into 4 grades of disability (I-IV) to guide treatment decisions.
🧬Diagnostic Logic & Scoring Breakdown
Each of the 5 questions asks about days affected in the past 3 months. Questions 1 and 3 count full days missed. Questions 2 and 4 count days with at least 50% reduced productivity (counted at half value in some scoring systems; the full count method is used here per the original MIDAS validation). The total score determines the grade of disability.
📢Clinical Significance & Implications
Migraine affects 15% of the global population (1 billion people) and is the second leading cause of disability (years lived with disability) worldwide. The MIDAS questionnaire is the most widely used tool for quantifying migraine-related disability and is recommended by the American Headache Society and International Headache Society guidelines for guiding treatment decisions, particularly the need for preventive therapy.
💡 Clinical Assessment Scenario Example
Past 3 months: 5 days missed work, 8 days reduced work, 4 days missed household, 6 days reduced household, 3 days missed family. Total = 5+8+4+6+3 = 26. Grade IV — Severe disability. Recommend preventive therapy and neurology referral.
⚠️Clinical Assessment Pitfalls
❌ Mistake: Forgetting to specify the 3-month recall period when administering MIDAS
✅ Correction: Always specify "over the past 3 months" when asking each question. The 3-month window provides a more representative sample of headache burden than shorter periods.
🚑When to Seek Medical Attention
This reference supports clinical assessment of Migraine; it does not replace urgent evaluation. Seek prompt in-person medical care if symptoms are severe, rapidly worsening, or life-threatening, or if you are unsure about a diagnosis or treatment plan. Patients should always consult their physician before starting or changing any therapy.
❓Frequently Asked Questions
Q: How does MIDAS score guide preventive therapy decisions?
MIDAS Grade III-IV (score ≥11) indicates moderate to severe disability and warrants strong consideration of preventive therapy. Grade II (score 6-10) may benefit from prevention if attacks are frequent or acute treatment is contraindicated. Grade I (score 0-5) can usually be managed with acute treatment alone. The American Headache Society consensus statement recommends offering prevention to patients with MIDAS ≥11.
Q: What is the difference between MIDAS and HIT-6?
MIDAS measures the number of days lost due to headache (lost productivity), while HIT-6 measures the overall impact of headaches on quality of life. HIT-6 includes questions about pain severity and emotional impact that MIDAS does not. Both are validated, and many headache specialists use them together for comprehensive assessment. MIDAS may be slightly better for quantifying economic burden, while HIT-6 captures subjective impact.
