A simplified diagnostic approach to dizziness in children

Abstract 

The objective of the study was to validate the effectiveness of a questionnaire and computer-assisted algorithm in diagnosing children with dizziness or vertigo. Dizziness and vertigo are common complaints in children, causing an extensive, often unnecessary evaluation. A pediatric “dizziness questionnaire” was designed and a computer-assisted algorithm was developed to facilitate the diagnostic task. A retrospective medical record review was conducted on all children presenting to the clinic for dizziness or vertigo throughout a 2-year period. The information was used by one investigator to complete the questionnaire and by the other, the algorithm. The two diagnoses thus obtained were compared by the third investigator to the medical record diagnosis. Sixty-two records were reviewed. The final diagnoses were migraine (39%), benign paroxysmal vertigo (15%), vestibular neuronitis (14%), and anxiety (13%). In 57 patients (92%), the questionnaire-derived diagnosis was identical to the medical record diagnosis. In 52 patients (84%), the algorithm-derived diagnosis matched the medical record diagnosis. The questionnaire and computer-assisted algorithm are reliable diagnostic screening tools for children with dizziness or vertigo. When these tools combined provide a clear-cut diagnosis, no further evaluation is necessary.Ravid S, Bienkowski R, Eviatar L. A simplified diagnostic approach to dizziness in children.
