Risk factors
Headaches, especially migraines, have a tendency to run in families. Four out of 5 migraine sufferers have a family history of migraines. Children who have migraines usually have at least one parent who also suffers from the condition. If one parent has a history of migraines, the child has a 50 percent chance of developing migraines, and if both parents have a history of migraines, the risk jumps to 75 percent. People with migraines may inherit abnormalities in certain areas of the brain, as well as the tendency to be affected by certain migraine triggers, such as fatigue, bright lights, or weather change.
