Children migraine syndrome: Definition and classification through the time

Even today, the migraine syndrome is not completeley defined knowing that it does not have either clear laboratory correlate or objectively defining marker. There is a great number of differential diagnostic references to define and classify migraine headaches; from Galen to ICHD-II (International Classification of Headache Disorders); from September 2003. Migraine syndrome represents a current problem of both paediatrics and children's neurology. The aim of this paper is to understand and define the migraine syndrome among children through the history of medical science, in order to enable the interpretation of the most acceptable defining and classification criteria of the children's migraine syndrome.
