ISOLATED EPILEPTIC VERTIGO AN UNDER RECOGNIZED FORM OF EPILEPSY

Abstract

BACKGROUND Epileptic vertigo (EV) is an uncommon but treatable form of epilepsy with vestibular symptoms as either the sole or predominant manifestation due to epileptiform discharges originating in vestibular cortex. OBJECTIVE To review the clinical characteristics and to establish the contribution of EEG in epileptic vertigo . A prospective SETTINGS AND DESIGN: observational study of fteen epileptic vertigo patients (7 females and 8 males) selected from outpatient clinic of neurology department at Dr S N medical college from the september , 2015 to august , 2018. METHODS AND MATERIAL: Their ages ranged from 15 to 40 years with mean age of onset 28 yrs. All patients , were subjected to neurological examination , interictal electroencephalogram (EEG), audiovestibular tests , cardiac test , carotid Doppler; brain stem evoked potential and brain MRI . STATISTICAL ANALYSIS USED:All data were expressed as mean or patient's number (n) and percentage (%) as appropriate . Fifteen epileptic vertigo patients (7 females and 8 male RESULTS: s) were included. Mean age of onset was 28yrs . symptoms of Dizziness[n=4(26.6%)], true vertigo [n= 9(60%)], vertigo with nausea [n=2 (13.33%)]. EEG was abnormal in all patients . Most common site involved is temporal lobe [n= 15 (100%)] and there was a right hemisphere predominanace [n= 8 (53.33%) ] in our study. MRI brain was normal in all (100%). All patients responded well with anti epileptic drugs. Vertigo c CONCLUSIONS: an be a form of focal epilepsy. EEG has an important role in diagnosing epileptic vertigo.
