BPPV consists of recurrent, transient rotatory vertigo and nystagmus associated with head movement in the plane of the affected semicircular canal. <br>It is usually idiopathic, but may follow head injury or ear pathology. <br>The posterior semicircular canal is most commonly involved. <br>It is due to loose otoconial debris (canaliths) exerting an effect on the vestibular sensors in the ampulla of the semicircular canals. <br>The Dix-Hallpike test is diagnostic, producing characteristic nystagmus. <br>The torsional nystagmus occurs after a latent period and lasts < 1 minute. <br>Canalith-repositioning manoeuvres are usually curative. <br>Brandt-Daroff exercises are a useful patient-led alternative.
