Was ist MIDAS Migraine Disability Assessment?

▾

The Migraine Disability Assessment (MIDAS) questionnaire is a validated patient-reported outcome measure that quantifies the impact of migraine headaches on daily functioning over the previous three months. Developed by Richard Lipton and Walter Stewart in the late 1990s, MIDAS was designed to be a simple, self-administered tool that captures disability across three domains of activity: paid work or school, household chores, and family, social, or leisure activities. The questionnaire consists of five core items asking patients to report the number of days in the past three months on which migraine caused them to miss school or work, to be at least 50% less productive at work or school, to miss household work, to be at least 50% less productive in household work, and to miss family or social activities. These five scores are summed to produce a total MIDAS score ranging from 0 to 90 or beyond, which is then classified into four disability grades: Grade I (0-5, minimal or infrequent disability), Grade II (6-10, mild or infrequent disability), Grade III (11-20, moderate disability), and Grade IV (21 or above, severe disability). The MIDAS score is used clinically to guide treatment intensity and matches patients to appropriate preventive versus acute therapies. It is also widely used in clinical research and health economic studies to demonstrate the burden of migraine. Crucially, it assesses functional impact rather than pain intensity, making it a more meaningful measure of treatment success.

Anleitung MIDAS Migraine Disability Assessment

▾
  1. 1Ask the patient to recall the past 3 months specifically, as the recall period is standardised to ensure comparability across assessments.
  2. 2Record Q1: number of days missed at work or school due to migraine (0 to ~90).
  3. 3Record Q2: number of days at work or school with productivity reduced by 50% or more due to migraine.
  4. 4Record Q3: number of days missed from household chores or errands due to migraine.
  5. 5Record Q4: number of days when household chore productivity was reduced by 50% or more.
  6. 6Record Q5: number of days missed from family, social, or leisure activities due to migraine.
  7. 7Sum all five values to get the MIDAS score and classify: 0-5=Grade I (minimal), 6-10=Grade II (mild), 11-20=Grade III (moderate), ≥21=Grade IV (severe); use the grade to match treatment intensity.

Gelöste Beispiele

▾
Beispiel 1Grade I — Minimal Disability
Gegeben:Patient with 1 migraine/month, misses 1 day of work, slightly reduced productivity 2 other days
Ergebnis:MIDAS = 4 — Grade I (Minimal disability)

Acute therapy only; reassess if frequency increases

Low total indicates migraine is not significantly disrupting daily life. Simple analgesics or triptans as needed are usually sufficient.

Beispiel 2Grade III — Moderate Disability
Gegeben:Patient missing work 3 days, reduced at work 5 days, housework affected 4 days, social events missed 3 days
Ergebnis:MIDAS = 17 — Grade III (Moderate disability)

Consider prophylactic therapy; specialist referral appropriate

Significant but not severe impact. This patient is a candidate for preventive treatment such as topiramate, amitriptyline, or a CGRP antagonist.

Beispiel 3Grade IV — Severe Disability
Gegeben:Patient bedridden with migraine 5 days/month, missing 8 work days, 10 housework days, 6 social days over 3 months
Ergebnis:MIDAS = 36 — Grade IV (Severe disability)

Urgent preventive therapy and specialist migraine clinic referral

Score above 21 indicates migraine is severely affecting all domains of life. Comprehensive preventive therapy (CGRP mAbs, onabotulinumtoxinA) should be considered.

Beispiel 4Post-Treatment Reassessment
Gegeben:Same patient 6 months after starting CGRP monoclonal antibody
Ergebnis:MIDAS = 6 — Grade II (Mild disability)

Treatment response confirmed — continue current regimen

Reduction from Grade IV to Grade II demonstrates significant treatment benefit. MIDAS is used as a before/after measure to quantify response to preventive therapy.

Häufig gestellte Fragen

▾
Q

How often should MIDAS be completed?

A

Recalculate Migraine Disability whenever a significant input changes — for example, when rates are updated, new measurements become available, costs are revised, or time horizons shift. In fast-moving health and medical environments, monthly or quarterly recalculation is prudent. For one-time decisions, running the calculation with multiple scenarios (optimistic, baseline, and conservative) at the time of the decision is usually sufficient. Tracking results over time creates a valuable record that reveals trends, validates earlier assumptions, and supports more accurate forecasting in future planning cycles.

Q

What is the difference between MIDAS and HIT-6?

A

Migraine Disability is a specialized calculation tool designed to help users compute and analyze key metrics in the health and medical domain. It takes specific numeric inputs — typically drawn from real-world data such as measurements, rates, or quantities — and applies a validated mathematical formula to produce actionable results. The tool is valuable because it eliminates manual calculation errors, provides instant feedback when exploring different scenarios, and serves as both a decision-support instrument for professionals and a learning aid for students studying the underlying principles.

Q

What are the different grades of migraine-related disability according to the MIDAS questionnaire?

A

The MIDAS questionnaire categorizes migraine-related disability into four grades: Grade I (0-5 points), Grade II (6-10 points), Grade III (11-20 points), and Grade IV (21 or more points). These grades are calculated based on the number of days in the last 3 months that migraine symptoms forced the patient to miss work, school, or other activities. For example, if a patient missed 3 days of work and 2 days of household work due to migraine, their MIDAS score would be 5 points, placing them in Grade I. Understanding these grades helps clinicians assess the severity of migraine-related disability.

Q

How does the MIDAS questionnaire account for the impact of migraine on household work and other activities?

A

The MIDAS questionnaire assesses the impact of migraine on household work and other activities by asking patients to report the number of days in the last 3 months that they were unable to do household work or chores due to migraine. This includes activities such as cleaning, cooking, and childcare. For each day that household work was missed, 1 point is added to the MIDAS score. For example, if a patient missed 4 days of household work due to migraine, 4 points would be added to their MIDAS score. This helps clinicians understand the broader impact of migraine on daily life.

Q

Can the MIDAS questionnaire be used to track changes in migraine-related disability over time?

A

Yes, the MIDAS questionnaire can be used to track changes in migraine-related disability over time. By administering the questionnaire at regular intervals, such as every 3 months, clinicians can monitor changes in a patient's MIDAS score and adjust treatment plans accordingly. For instance, if a patient's MIDAS score decreases from 18 to 12 over a 6-month period, it may indicate that their current treatment plan is effective in reducing migraine-related disability. This information can be used to make informed decisions about treatment and improve patient outcomes.

Häufige Fehler vermeiden

▾
  • !Counting total headache days rather than days where headache caused the specific functional impairment described in each question.
  • !Double-counting the same day across multiple questions — the same day of missed work and missed housework correctly scores 1 point on each relevant question.
  • !Using a recall period other than 3 months — some clinicians ask about 'last month', making scores incomparable to published norms.
  • !Ignoring Q3 and Q4 (housework items) in employed patients, missing a significant disability domain particularly relevant for primary caregivers.
  • !Treating MIDAS as a pain intensity scale — it measures lost function, not pain severity.
  • !Failing to document whether high scores reflect medication overuse headache versus true migraine burden, which changes treatment priority.
💡

Profi-Tipp

Use MIDAS together with a headache diary to fully characterise migraine burden. The diary provides attack frequency and acute medication use data that MIDAS alone does not capture, and medication overuse can be identified before prescribing preventive therapy.

Wussten Sie?

When the MIDAS questionnaire was first validated, researchers discovered that patients systematically underreported their disability on physician-directed interviews compared to the anonymous self-completed questionnaire. This highlighted that migraine carries substantial hidden disability not captured in standard clinical consultations.
