Introduction

Vertigo is an unpleasant distortion of static gravitational orientation, or an erroneous perception of motion of either the sufferer or the environment. It is not a well-defined disease entity, but rather may be the outcome of many pathological or normal processes. It is best described as a multisensory syndrome which is induced either by stimulation of the intact sensory systems by motion, or by pathological dysfunction. Different treatments are appropriate for different types of vertigo, and may include drug therapy, physical therapy (exercises), surgery and psychotherapy.
