Inclusion criteria
Inclusion criteria: 1.Those whose video head impulse test result is 0.7 or less in at least 1 of the anterior, lateral, or posterior semicircular canals on unilateral. 2.Those whose video head impulse test result is 0.7 or less in at least 1 of the anterior, lateral, or posterior semicircular canals on bilateral. 3.Persons who meet all of the diagnostic criteria for PPPD (hereinafter A to E) A.One or more symptoms of dizziness, unsteadiness, or non-spinning vertigo are present on most days for 3 months or more. B.Persistent symptoms occur without specific provocation, but are exacerbated by three factors: Upright posture, active or passive motion without regard to direction or position, and exposure to moving visual stimuli or complex visual patterns. C.The disorder is precipitated by conditions that cause vertigo, unsteadiness, dizziness, or problems with balance including acute, episodic, or chronic vestibular syndromes, other neurologic or medical illnesses, or psychological distress. D.Symptoms cause significant distress or functional impairment. E.Symptoms are not better accounted for by another disease or disorder.
Exclusion criteria
Exclusion criteria: 1.Patients with structural abnormalities in MRI and MRA. 2.Patients who do not meet the diagnostic criteria for persistent postural perceptual dizziness and whose video head impulse test results in all semicircular canals are 0.7 or more. 3.Patients who are diagnosed with benign paroxysmal positional vertigo based on the results of the Dix-Hallpike test or roll test.
