Abstract:
This content focuses on some of the less common causes of dizziness in the adult. The diseases have been divided into the 2 broad categories of those causing chronic symptoms and those causing episodic symptoms. Presented here are the unusual causes of chronic disequilibrium in the adult, including bilateral vestibular loss, progressive supranuclear palsy, spinocerebellar ataxias, and mal de debarquement. Also discussed are the unusual causes of episodic disequilibrium in the adult, including psychogenic disequilibrium, vestibular paroxysmia, episodic ataxia, vestibular seizures, and cervicogenic vertigo.
