BPPV (benign paroxysmal positional vertigo) causes an eyeball twitch known as nystagmus. Depending on the nystagmus orientation, the appropriate maneuver to treat the BPPV varies. Video demonstrates all the different types of nystagmus, how it is described, and how it can be treated whether Epley, Gufoni, Deep-Head Hanging, Semont, BBQ, or Half-Somersault.

Do keep in mind that if nystagmus is absent (but you are dizzy)... or if the nystagmus persists even when totally still for more than 10 minutes, you do NOT have BPPV and some other cause for dizziness must be pursued. General flowchart to diagnose most types of dizziness can be found here: [ Ссылка ]
