ABSTRACT

Background: Vertigo is the term used to describe the illusory perception of movement. This, and the dizziness, cause spatial disorientation, anxiety, anguish, depression and a perception of functional handicap which cannot be quantified with the conventional vestibulometric techniques. The impact of this symptom, especially if it’s chronic, exceeds simple organic involvement. The Dizziness Handicap Inventory (DHI) has been designed to evaluate this impact in the patient’s daily life, from his own perspective. Methods: This is an observational, descriptive, prospective and survey study; performed between March of 2000 and October of 2003 at the Otolaryngology Department of the Centro Médico Nacional Siglo XXI. There were 159 patients with vertigo or dizziness, with a duration of at least 5 months; the questionnaire was applied to them in order to analyze their answers and obtain a final score. Results: The physical handicap was the feature more frequently affected (82%), followed by the functional feature (55%), and finally, the emotional one (48%). The internal consistency (Cronbach’s a) was a acceptable for the sample. Conclusion: The DHI is a useful, practical and valid instrument to evaluate the impact of vertigo in the patient’s quality of life.
