Four episodic syndromes are recognized in the current version of the International Classification of Headache Disorders (ICHD): cyclic vomiting syndrome (CVS); abdominal migraine; benign paroxysmal vertigo; benign paroxysmal torticollis. Previously called childhood periodic syndromes, they are thought to be early expressions of a migrainous spectrum. They usually occur in childhood or adolescence and some of these patients will develop migraine later in childhood or in adulthood. More rarely, some of these disorders, in particular CVS and abdominal migraine, can persist or even begin at adulthood. The concept of episodic syndromes associated with migraine in adults is relatively recent, recognized for the first time in the version III-beta of the ICHD (2013). It is important for the adult neurologist to recognize the clinical pattern of these disorders. Lack of knowledge of these disorders often leads to delayed diagnosis, and a large number of complementary tests. Treatments are often borrowed from migraine abortive and preventive treatments. This review summarizes the characteristics of episodic syndromes and is particularly focused on data in adults.
