TY - CHAP M1 - Book, Section TI - DIZZINESS AND VERTIGO A1 - Walker, Mark F. A1 - Daroff, Robert B. A2 - Hauser, Stephen L. A2 - Josephson, S. Andrew PY - 2018 T2 - Harrison's Neurology in Clinical Medicine, 4e AB - Dizziness is an imprecise symptom used to describe a variety of sensations that include vertigo, light-headedness, faintness, and imbalance. When used to describe a sense of spinning or other motion, dizziness is designated as vertigo. Vertigo may be physiologic, occurring during or after a sustained head rotation, or it may be pathologic, due to vestibular dysfunction. The term light-headedness is commonly applied to presyncopal sensations due to brain hypoperfusion but also may refer to disequilibrium and imbalance. A challenge to diagnosis is that patients often have difficulty distinguishing among these various symptoms, and the words they choose do not reliably indicate the underlying etiology.
