The aim of our study was to know the incidence of vertigo, to study the clinical pattern and presentation of patient with vertigo, to study the role of history taking, clinical neurotological tests and laboratory tests in diagnosis of vertigo and to establish the site of lesion and etiology using proper examination and investigation parameter. A total of 80 patients presenting with vertigo were studied. The clinical diagnosis was made after detailed history taking, otoneurological examination, relevant audiovestibular tests and radiological tests where ever needed. In our study vertigo was more common in males. Peripheral vertigo was found in 52 cases and central vertigo in 28 cases. Amongst the peripheral causes BPPV (44.23), Menieres disease (19.23 %) and vestibular neuritis (13.46 %) were three common causes in descending order. The central causes include cervical vertigo (25 %), VBI (14.28 %) and Migraine (14.28 %) were three common causes in descending order. Results of our study were compared with the published data available in the literature.
