Abstract
BACKGROUND: The purpose of this review is to clarify the natural course of benign paroxysmal torticollis (BPT) and update the information on the relationship of this disorder with migraine. BPT belongs to a group of "episodic syndromes that may be associated with migraine" and is diagnosed according to diagnostic criteria of the International Classification of Headache Disorders, 3rd edition. BPT affects infants and young children and is often an underdiagnosed manifestation since it is not recognized in cases with a benign evolution, requiring a careful differential diagnosis. It was first described by Snyder in 1969 as a movement disorder, a cervical dystonia consequent to labyrinthic disorder. MATERIALS AND METHODS: The PubMed and Web of Science databases were consulted from 1968 to 2024, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. RESULTS: In total, 113 articles were identified, 86 selected, and 25 considered for the purpose of this review. Clinical studies were considered in relation to evolution, cognitive, and motor development; genetic and not genetic etiology; the relationship with migraine with and without aura; vestibular migraine; hemiplegic migraine; and paroxysmal vertigo.
