Aetiology – believed to be due to free-floating endolymph particles in semi-circular canal. 
  • Most cases (60-70%) are idiopathic
  • Secondary BPPV may be due to 
    • Head trauma (7-17% of all cases of BPPV) 
    • Viral (up to 15% of all cases of BPPV)
    • Meniere’s disease (around 5% of cases of BPPV) 
    • Migraines (less than 5% of all cases of BPPV) 

Diagnosis:  Dix-Hallpike manoeuvre – look for nystagmus 

Treatment: Epley’s manoeuvre – series of head movements with the purpose of encouraging any foreign material out of the canal and into the utricle
