Evaluation of the dizzy patient

This discussion has focused primarily on the history and physical examination of the patient with dizziness which, in fact, are the two most important elements in the evaluation process. To perform the examination expeditiously and completely, a broad differential diagnosis of dizziness must be kept in mind. The clinician should also keep in mind two basic objectives: first, to identify serious pathology (e.g., central nervous system lesion, brainstem ischemia, cardiac arrhythmia); and second, to recognize diseases that can be specifically treated, such as an endocrine abnormality, middle ear infection, Meniere's disease, or a drug reaction. Reassurance and/or vestibular rehabilitation are the mainstays of therapy for the patients not falling into the above two categories.
