[Is migraine a progressive cerebral disease?].
Migraine is a primary neurovascular headache which affects approximately 12% of the adult population. Migraine particularly affects women of working age and is associated with significant disability and reduced quality of life. During migraine attacks, the capacity to engage in daily activities such as child care, work, and social activities is reduced, and relationships with family members and friends become strained. In this respect, migraine places a heavy economic burden on both the individual and society. It is also known migraine is a risk factor for ischemic stroke in young women with migraine with aura. Recently, it was reported that some individuals that experience migraine with and without aura may be at an increased risk for subclinical lesions in certain areas of the brain. Cerebral white matter lesions (WMLs) are a common finding on cerebral MRI scans. Although, it appears that cerebral WMLs are more common in migraineurs than in the general population, the nature, association and the clinical significance of cerebral WMLs in migraineurs are not yet conclusive. Furthermore, there is no good evidence to support the notion that cerebral WMLs in migraineurs can predict subclinical or clinical stroke in these individuals. Needless to say, the need for more longitudinal and prospective migraine research is immense. The aim of the future migraine research should be to obtain more information about the natural course of migraine as well as evaluate the association between migraine and cerebral WMLs and their consequences. In addition, continuing genetic identification of key proteins involved in migraine will improve our understanding of this common and sometimes most debilitating disorder, which can strike during the most productive years of a person's life.
