  • Title: Vertigo and dizziness--a clinical approach.
    Author: Mukherjee A, Chatterjee SK, Chakravarty A.
    Journal: J Assoc Physicians India; 2003 Nov; 51():1095-101. PubMed ID: 15260396.
    Abstract:
    Dizziness is a term which is used to describe a variety of sensations. It is possible to group these complaints into four types: a rotational sensation (Type I dizziness), impending faint (Type II dizziness), dysequilibrium (Type III dizziness) and vague lightheadness (Type IV dizziness). Type I dizziness or vertigo is due to disease of the vestibular system--peripheral or central, and is characterized by a feeling of movement relative to one's surrounding. The majority of dizzy patients, however, belong to Types II, III and IV, collectively called the non-vestibular system disorders. The distinction is usually possible by a detailed history and clinical examination, but some special bedside tests--the dizziness simulation battery--are often required for properly distinguishing the various types of dizziness. Important causes of vertigo and the non-vestibular system disorders have been discussed with focus on benign positional vertigo, acute peripheral vestibulopathy, Menieres' disease, toxic damage to labyrinths, perilymph fistula, cerebrovascular disease, multiple sclerosis, cerebellopontine angle tumors, basilar migraine, vestibular epilepsy, cervical vertigo and phobic postural vertigo.
