کیا ہے 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.

MIDAS Score = Q1 (missed work/school days) + Q2 (reduced work/school days ≥50% less productive) + Q3 (missed housework days) + Q4 (reduced housework days ≥50% less productive) + Q5 (missed family/social/leisure days); Range 0 to unlimited (typically capped at 90 for a 3-month window)متغیر کی تشریح

▾
- 1Ask the patient to recall the past 3 months specifically, as the recall period is standardised to ensure comparability across assessments.
- 2Record Q1: number of days missed at work or school due to migraine (0 to ~90).
- 3Record Q2: number of days at work or school with productivity reduced by 50% or more due to migraine.
- 4Record Q3: number of days missed from household chores or errands due to migraine.
- 5Record Q4: number of days when household chore productivity was reduced by 50% or more.
- 6Record Q5: number of days missed from family, social, or leisure activities due to migraine.
- 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.

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.
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.
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.
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.

Professionals in health and medical use Migraine Disability as part of their standard analytical workflow to verify calculations, reduce arithmetic errors, and produce consistent results that can be documented, audited, and shared with colleagues, clients, or regulatory bodies for compliance purposes.
University professors and instructors incorporate Migraine Disability into course materials, homework assignments, and exam preparation resources, allowing students to check manual calculations, build intuition about input-output relationships, and focus on conceptual understanding rather than arithmetic.
Consultants and advisors use Migraine Disability to quickly model different scenarios during client meetings, enabling real-time exploration of what-if questions that would otherwise require returning to the office for detailed spreadsheet-based analysis and reporting.
Individual users rely on Migraine Disability for personal planning decisions — comparing options, verifying quotes received from service providers, checking third-party calculations, and building confidence that the numbers behind an important decision have been computed correctly and consistently.

MIDAS Score Grades and Clinical Implications

| Grade | Score | Disability Level | Typical Management |
|---|---|---|---|
| I | 0-5 | Minimal or infrequent | Acute therapy only (OTC analgesics, triptans) |
| II | 6-10 | Mild or infrequent | Optimise acute therapy; consider preventive if attacks frequent |
| III | 11-20 | Moderate | Preventive therapy recommended; specialist review |
| IV | ≥21 | Severe | Comprehensive preventive therapy; CGRP mAbs, onabotulinumtoxinA |
اکثر پوچھے جانے والے سوالات
▾
What does MIDAS stand for?
In the context of Migraine Disability, this depends on the specific inputs, assumptions, and goals of the user. The underlying formula provides a deterministic relationship between inputs and output, but real-world application requires interpreting the result within the broader context of health and medical practice. Professionals typically cross-reference calculator output with industry benchmarks, historical data, and regulatory requirements. For the most reliable results, ensure inputs are sourced from verified data, understand which assumptions the formula makes, and consider running multiple scenarios to bracket the range of likely outcomes.
How often should MIDAS be completed?
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.

What is the difference between MIDAS and HIT-6?
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.

عام غلطیاں جن سے بچنا ہے
▾
- !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.
پرو ٹپ
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.
کیا آپ جانتے ہیں؟
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.
