MIGRAINE CAUSES

In up to 70 percent of cases migraine is inherited. However, the exact mode of inheritance is poorly understood. Evidence shows that complex genetic factors can increase the chance of developing migraine by fourfold. If both parents suffer from migraine then you have a 75 percent chance of developing migraine. If one parent suffers then you have a 50 percent chance. Most patients experience their first attack by their late teens. However, a 25-year-old’s risk of developing migraine is still much greater than the general population when both parents suffer from migraine.
