Sodium Channel Blockers for Vestibular Paroxysmia in Children.

As vestibular paroxysmia (VP) has recently been described in children, with an incidence of up to 4% of vertigo, and a promising therapeutic response to sodium-channel-blocking drugs has also been reported, the aim of this paper is to review the available literature on this topic and to provide the best possible guidance for diagnosis and treatment. : PubMed, Medline, Cochrane, and Crossref databases were searched, and all studies on VP in children and sodium channel blockers were selected. : Only five articles reporting small case series or single case reports were identified. To date, oxcarbazepine (OXC) and carbamazepine (CBZ) are the only two molecules prescribed. The recommended doses were 300 to 360 mg/day and 50 to 200 mg/day for OXC and CBZ, respectively, for a total duration of 6 weeks. Fast efficacy (one week) was reported. : VP has been identified in pediatric patients and appears to respond to sodium channel blockers in a manner similar to adults. Only a limited number of cases have been reported to date; thus, there is a need to raise awareness about this treatable cause of episodic vertigo in children.
