Abstract

Non-vestibular dizziness is a common complaint in patient who seeking dizzy clinic. Patients with non-vestibular dizziness presented their dizziness as light-headed, free floating sensation, or dissociated from body whereas patients with vertigo usually complained of an illusion sensation of an environment (i.e., a sensation of spinning). It is known that non-vestibular dizziness is more common than vestibular dizziness with vertigo in dizzy outpatient clinic. Presyncopal light-headedness due to orthostatic hypotension and psychogenic dizziness are two common causes of non-vestibular dizziness. Here the author reviews the clinical features of non-vestibular dizziness and the keys to the differential diagnosis of non-vestibular dizziness from vestibular dizziness.
