A Clinical Epidemiological Study in 187 Patients with Vertigo

Abstract

A retrospective study to investigate the clinical epidemiological characteristics of vertigo was carried out on 187 patients with vertigo. A clinical history for each patient was recorded precisely about the attack, frequency, and development of vertigo, its duration, intensity, and the accompanied symptoms including the risk factors for cerebrovascular disease, etc. All the patients were subjected to physical examination with special attention to neurologic systems and Dix-Hallpike maneuver, computed tomography/computed tomography-angiography (CT/CTA) and MRI scan were performed when necessary. Majority of the patients in this study suffered with posterior circulation ischemia (59.89%) and benign paroxysmal positional vertigo (16.04%). Other ailments that affected these patients included migraine, Meniere's disease (1.6%), sudden hearing loss (1.07%), vestibular neuronitis, multiple sclerosis, acute viral encephalitis, meningioma, neurosis, posttraumatic vertigo, acute myocardial infarction (0.53%), and neurosis (14.97%). It appeared that in comparison to younger patients the elderly population is likely to be more susceptible to vertigo. Vertigo attacks patients with various diseases, which pre-dispose the patients to this disease. Presentation of vertigo can be clinically diagnosed in most cases of patients suffering from posterior circulation ischemia.
