2001 WHO Report Ranks Migraine Among Top 20 Causes of Disability
The WHO report defines the "burden" of migraine to include the economic and emotional difficulties that a family experiences as a result of migraine, as well as the lost opportunities - the adjustments and compromises that prevent other family members from achieving their full potential in work, social relationships and leisure (Gallagher & Mechanic 1996)3. These human aspects of migraine are more difficult to assess and quantify, the report says, but are nevertheless vital to fully understanding the implications of the disorder.
The Global Burden of Disease (GBD) is an analysis of the onset of disorders and the disability caused by them. Using the GBD methodology, the report identifies six neuropsychiatric disorders2 among the top 20 causes of disability in the world: unipolar depressive disorders, alcohol use disorders, schizophrenia, bipolar affective disorder, Alzheimer's and other dementias, and migraine. The final results of the study will be published in 2002.
The report places migraine among all leading causes of disability in the world. Migraine is estimated to account for 2.0% years of life lost due to a disability in women of all ages. In both sexes of all ages, migraine is responsible for 1.4% of total years of life lost due to a disability (see tables below). Years of life lost to a disability is defined as years of "healthy" life lost in states of less than full health.
The WHO's recognition of migraine as a major global disorder, therefore, is a major step toward relieving the burden of headache around the world. The next step will be to develop global and regional education programmes that will increase public awareness of headache disorders, and to increase research for the development of effective headache therapies.
