Terms such as “vertigo” and “dizziness” have different meanings to different people, including different interpretations among medical practitioners, despite attempts to encourage semantic standardization. Research has shown that the specific term used (by a patient or by a physician) has nearly no diagnostic value; rather, it is more helpful to focus on features such as the onset of the symptom, whether it is continuous or episodic, its duration, associated symptoms, and exacerbating and ameliorating factors. In this work, we have elected to use the term “disequilibrium” because of its neutrality.
