Background: Dizziness ranks among the most common complaints in medicine. The termdizziness encompasses a variety of different sensations; each points in distinct diagnosticdirection. In the face of such diagnostic challenges and in the era of efficiency and costreduction, a simple, inexpensive, and accurate questionnaire-based diagnostic algorithmwould be highly welcome.Objectives: To develop an Arabic dizziness questionnaire for adults. Modification andapplication of the pediatric dizziness questionnaire in children, and to compare thequestionnaire conclusion with the results of vestibular evaluation.Subjects and Methods: Twenty dizzy adults aged 21-60 years, and 20 dizzy childrenaged 6-17 years were subjected to: an interview with patients using the Arabic dizzinesspediatric or adult questionnaire, otological examination, bedside examination for the dizzypatients, basic audiological evaluation, and vestibular assessment including:Videonystagmography(VNG), cervical vestibular evoked myogenic potentials (cVEMP), andSensory Organization Testing(SOT) via dynamic posturography. Parameters under studywere questionnaire scores and conclusion, VNG results including canal paresis, cVEMPlatency, amplitude,and threshold. SOT result analysis in the form of equilibrium scores andsensory analysis.Results: Comparisons and correlations between the vestibular score of the adult andpediatric questionnaires and the results of the vestibular assessment were non- statisticallysignificant. The most common diagnoses for dizziness in the adult group were vestibularneuritis (20%), ménière’s disease (20%), Benign paroxysmal positioning vertigo (15%),migraine associated dizziness (15%). The most common diagnoses in the pediatric groupwere Benign paroxysmal vertigo of childhood (20%), epilepsy (15%), migraine associateddizziness (10%), general causes (10%), vestibular disorder (10%), and cerebellopontine anglelesions (10%).Conclusion: Adult and pediatric patients sharing the same diagnosis consistently answeredcertain questions positively in the questionnaire. Children complaining of headache should becarefully evaluated as migraine associated dizziness and migraine equivalents are among themost common causes of dizziness in children. We recommend the use the dizzinessquestionnaires as a first step of the test battery for evaluation of dizzy patients
