MIDAS Migraine Disability Score Calculator
How much are your migraines actually costing you? The MIDAS questionnaire measures the real impact on your work, home life, and relationships — and tells you when it's time to escalate treatment.
"How bad are your migraines?" is a question most sufferers struggle to answer. Pain is subjective. But missed workdays, cancelled plans, and half-productive afternoons? Those are measurable. And that's exactly what the MIDAS score captures.
The Migraine Disability Assessment (MIDAS)was developed by neurologists Dr. Richard Lipton and Dr. Walter Stewart. It's been validated in clinical trials, used by headache specialists worldwide, and takes about 2 minutes to complete. The result? A single number that tells your doctor exactly how disabled your migraines are making you — which directly influences what treatment they recommend.
Why Your MIDAS Score Matters
Most people dramatically underreport how much migraines affect their life. You power through bad days, skip the party without thinking twice, and slowly adjust your expectations downward. The MIDAS questionnaire forces you to actually count the damage.
Here's why that number matters clinically:
- It changes your treatment. A Grade I patient gets different recommendations than a Grade IV. Higher scores justify more aggressive preventive treatment — CGRP inhibitors, Botox, beta-blockers — that doctors might not suggest for milder cases.
- It speeds up the conversation. Walking in with "I get headaches sometimes" is very different from "My MIDAS score is 34." The second one gets taken seriously immediately.
- It tracks progress. Retake MIDAS every 3 months while on treatment. A dropping score means it's working. A rising score means it's time to adjust.
The MIDAS Grading Scale
Little or No Disability
Headaches cause minimal impact. OTC treatment usually sufficient.
Mild Disability
Starting to interfere with daily life. Worth discussing with your doctor.
Moderate Disability
Significant impact on work, home, and social life. Preventive treatment recommended.
Severe Disability
Major disruption across all areas. Specialist referral and aggressive treatment warranted.

What to Do With Your Score
Bring It to Your Doctor
Print or screenshot your results. The MIDAS score is one of the most widely recognized disability measures in headache medicine — your neurologist will immediately understand what it means. Combined with a headache type assessment and a tracking diary, it gives your doctor a complete picture in under 5 minutes.
Retake It Every 3 Months
A single MIDAS score is a snapshot. The real value is tracking it over time. If you start preventive medication and your score drops from 32 to 12 after three months? That's strong evidence the treatment is working. If it stays at 32? Time to try something different.
Combine It With Daily Tracking
MIDAS measures the what — how many days you lost. Daily headache tracking reveals the why — which triggers, patterns, and circumstances drive your attacks. Together, they give your doctor everything needed to build a treatment plan that actually fits your life.

How Many Migraines Is Too Many?
This is one of the most common questions migraine sufferers search for — and the answer depends on context:
- 4+ migraine days per month — most headache specialists will discuss preventive treatment at this threshold
- 8+ migraine days per month — qualifies for most CGRP inhibitor treatments (Aimovig, Ajovy, Emgality)
- 15+ headache days per month (with at least 8 migraine-type) — clinical definition of chronic migraine, which opens additional treatment options including Botox
But frequency alone doesn't capture the full picture. Two migraines per month that each knock you out for 3 days is arguably worse than four migraines that each last 4 hours. That's why MIDAS measures disability, not just frequency — and why both numbers matter when talking to your doctor.
People Also Ask
Is the MIDAS questionnaire the same one doctors use?
Yes. The MIDAS is the same validated questionnaire used in clinical settings worldwide. It was developed by headache researchers and published in the journal Neurology. Many neurologists use it as a standard intake tool and ask patients to retake it quarterly to track treatment effectiveness.
What if my score seems too low but I still feel disabled?
MIDAS captures missed and reduced-productivity days, but some impacts are harder to quantify — anxiety about the next attack, avoiding trigger situations, reduced quality of life even on "good" days. If you feel your headaches are a significant problem, tell your doctor regardless of the score. MIDAS is one tool, not the whole picture.
Can I use MIDAS for tension headaches, not just migraines?
MIDAS was designed and validated for migraines specifically, but it measures disability from any headache type. If tension headaches are significantly impacting your daily life, the questionnaire is still useful — it quantifies the impact in a way your doctor can act on. Not sure which type you have? Take the migraine vs headache quiz first.
What treatments are available for high MIDAS scores?
Grade III-IV scores typically warrant preventive treatment. Options your doctor may discuss include: daily preventive medications (beta-blockers, topiramate, amitriptyline), CGRP monoclonal antibodies (monthly injections), gepants (oral CGRP blockers), Botox injections (for chronic migraine), neuromodulation devices, and lifestyle modifications. The right choice depends on your specific situation, which is why tracking data matters.
