History is very important in the diagnosis of Crystal Shift Disease. When this disease is suspected, the diagnosis is made with a maneuver called the 'Dix-Hallpike' maneuver. When the diagnosis is made with this maneuver, the crystals are placed in place by using gravity with a maneuver called the 'Epley' maneuver in the treatment, and the patient is thus treated. The effectiveness of even a single treatment maneuver is very high. In the Epley treatment maneuver, the patient is informed about which position to sleep for 10 nights. After the 10th night, the patient can sleep in the normal position. The place of drug therapy in the treatment of positional vertigo is very small. Rarely, if the patient experiences excessive nausea and vomiting during diagnosis-treatment maneuvers, anti-nausea drugs can be used.
