Migraines can occur in children as young as four years of age; most boys will outgrow migraines by their early teens. Girls, however, usually experience more migraines as they enter adolescence as a result of hormonal changes. Most children who have migraines have inherited the tendency, especially if they also experience motion sickness.
Cause of migraines are often called “vascular headaches” because they occur when the blood vessels constrict or expand. Although constricting blood vessels do not cause pain, they can temporarily affect vision or balance. It is when blood
vessels dilate, however, that their expansion triggers pain. In some children, certain things trigger a migraine, such as stress, a change in routine or
sleep patterns, bright lights, loud noises, or certain foods and beverages.
