Migraine Q&A - Is migraine inherited?

Yes. The exact mode of inheritance is poorly understood. Complex genetic factors are involved increasing its risk up to fourfold. If both parents suffer from migraine then you have about an 80% chance of developing migraine. If one parent suffers then you have a 60% chance. Most migraineurs have experienced their first attack by their late teens. A 25-year-old's risk of developing migraine is still much greater than the general population when both his/her parents suffer from migraine. Some years ago, a major breakthrough was made in this field when scientists discovered that an abnormality on Chromosome 19 passed on through families was responsible for a rare type of migraine called Familial Hemiplegic Migraine.
