Studies on headache burden are mostly performed to show the size of the public health problem. This chapter, dealing with the noneconomic aspects of headache burden, describes the methods and validated instruments to measure disability and reduction in the quality of life due to headache and refers some interesting results from such studies. Most studies until now have dealt with migraine, but there are also some studies on headache in general and cluster headache in particular. According to disease burden assessments by the World Health Organization, migraine alone may be among the 20 most disabling conditions worldwide. For tension-type headache, there are not sufficient data yet. Some data indicate that this headache type, due to its high prevalence, may entail a higher burden than migraine. Part of the headache burden may be due to psychiatric comorbidities of headache. A few studies indicate that headaches may lead to reductions in quality of life that are higher than in many other chronic disorders. The interictal burden of, e.g., migraine and cluster headache is probably mostly related to worry for later attacks and restrictions in lifestyle to avoid attacks, but some people also fail to recover completely. It has also been shown that migraine, in several ways, influences the lives of partners and children.
