Potential of the Migraine Disability Assessment (MIDAS) Questionnaire as a public health initiative and in clinical practice

Migraine is not always well managed in clinical practice, often being under-diagnosed and undertreated. As a result, many sufferers never consult a physician or lapse from care after physician contact. Although most migraine care is provided by general practitioners, others, including specialists, emergency room physicians, pharmacists, and alternative practitioners, may also be involved. A method of standardizing clinical information about migraine is essential for coordinated, logical, and systematic care. The impact of migraine on the patient is an important clinical parameter but one that is seldom inquired about, perhaps because it exhibits such marked variability among and within individuals. Headache-related disability can be an objective and measurable index of this impact. The Migraine Disability Assessment (MIDAS) Questionnaire is a simple and validated instrument with potential for use in clinical practice, research, and public health. It can improve communication between patients and health-care professionals regarding the impact of migraine which, in turn, allows tailoring of the intensity of treatment to the severity of the illness. Changes in the MIDAS score may serve as an end point in assessing treatment efficacy. In populations, MIDAS scores may indicate the burden of migraine in the community and spark public health initiatives to improve management.
