How early in childhood can a migraine show up?
A migraine can occur very early in the course of the life of a child, as young as 1-2 years of age or may be even earlier. Colickiness in children may be one of the early signs of migraine. In fact, a large number of infants who are colicky go on to have migraines in later life. Early and significant motion sickness may also be a sign of early migraine tendency. Up to 39% of children and 70% of adolescents experience at least an occasional headache. Migraine headaches can begin at any time during childhood and may affect up to 5% of all school-age children.
