[Vertigo in children].

Oto-neurologic investigation in the child with vertigo is fundamentally important. In 3% of cases, it reveals the presence of a cerebral tumour. Technical difficulties in examining a child under 5 years of age stem from their fear of the dark, insecurity in a medical setting and a labile attention span. Major causes are migraine (in 28% of cases) and childhood idiopathic paroxysmal vertigo, and recurring vestibular disorders (13% of cases). Classic disorders such as Ménière's disease are rare in the child (3% of cases), as are benign paroxysmal positional vertigo and cupulolithiasis (only 5% of children with vertigo).
