[An etiological analysis of 367 neurological outpatients with complaint of vertigo]
1Department of Neurology, Navy General Hospital, Beijing 100037, China.
Objective:
To explore the etiology of patients with chief complaint of vertigo in the department of neurology in order to reduce the rate of misdiagnosis.
Methods:
A total of 367 patients with chief complaint of vertigo in our department of neurology were followed up. The associated medical history, symptoms and physical examination were obtained.
Results:
The main diagnoses for the 367 patients were benign paroxysmal positional vertigo (BPPV) (219, 59.7%), posterior circulation ischemia (PCI) (65, 17.7%), migraine (31, 8.4%), hypertension (18, 4.9%) and psychogenic vertigo (17, 4.6%).
Conclusions:
Presentation of vertigo can be clinically diagnosed in most diseases, with the most common cause of BPPV. Combination of the prominent clinical features, physical examinations and especially Dix-Hallpike maneuver may guide the general physicians to a most proper cause of vertigo.
