About migraine
Migraine is a complex genetic neurological disorder that affects up to 1 in 5 people. It is a spectrum disorder, rendering some completely disabled, while others are able to live fairly normal lives with only the occasional attack. It is an invisible disability, not a temporary condition, nor something that will go away. There is no cure for migraine, however, in most cases, it can be managed.
The research around migraine is rapidly changing, with significant breakthroughs in recent years. We now understand all migraine to have a genetic cause. Some types are caused by a single gene defect, and others are polygenetic or a combination of a number of genes.
