Episodic Syndromes That May Be Associated With Migraine: AKA the Childhood Periodic Syndromes

The specific disorders reviewed in this article include: benign paroxysmal torticollis, benign paroxysmal vertigo, abdominal migraine, and cyclical vomiting syndrome, as well as infantile colic, which was recently added under the appendix section in ICHD-III beta.
