Irregularities of nystagmus can be found almost in every electronystagmographic record, but only a few are pathological. In this investigation, the authors try to define the border line between pathological and nonpathological irregularities of nystagmus and according to this measure the diagnostic use of findings of irregularities of nystagmus.

Objectives: We examined the association between the size and cross-sectional area of the superior vestibular nerve as measured on constructive interference in steady-state (CISS) parasagittal magnetic resonance imaging (MRI) and the vestibular nerve function as measured by electronystagmography.
Methods: The retrospective observational cohort study took place at an academic tertiary referral center. Twenty-six patients who met established clinical and electronystagmographic criteria for vestibular neuritis and who underwent parasagittal CISS MRI were identified.

Background: The probable cause of Benign Paroxysmal Positional Vertigo (BPPV) is a degeneration of the oto lithic organs (utricle and saccule). The aim of the study is to find possible alterations in Vestibular Evoked Myogenic Potentials (VEMP) recordings in BPPV patients, because the saccule is part of the VEMP pathway.
Material/methods: 27 BPPV patients (24 unilateral and 3 bilateral) aged 20 to 70 years and 30 healthy age matched controls.

Objective: Multiple sclerosis (MS) may give rise to a variety of clinical signs and symptoms including vertigo and/or other problems related with equilibrium. In this study, we aimed to evaluate clinical and electronystagmographical (ENG) characteristics of relapsing remitting MS (RRMS) patients.
Design: This is a prospective controlled study consisting of 30 patients who were diagnosed as definite RRMS according to McDonald's diagnostic criteria and 30 healthy individuals.

Purpose: To study the audiovestibular functions in cases of migraine with or without vertigo.
Materials And Methods: This was a prospective study involving 50 cases of migraine who were divided into 2 groups: patients with vertigo and those without. All patients underwent a detailed otological and neurootological examination followed by full audiological and vestibular investigation including pure tone audiometry, speech reception threshold, speech discrimination score, tone decay, short increment sensitivity index, auditory brainstem-evoked responses, and electronystagmography (ENG).
