Migraine can affect people of all ages, but it usually starts in the early teenage years. Some younger children may suffer migraine attacks, but they may be of shorter duration and not associated with symptoms as severe as are typically seen in later years.
Studies report that up to the mid to late teens, around one in ten boys get migraine headaches, and around half as many girls. By the early twenties, that ratio is reversed and about one in five girls report recurrent migraines, compared to about one in six boys. Throughout adult life, the ratio of females to males keeps increasing until in later years, nearly three times as many women are suffering from migraines as men.
