Vestibular evaluation in patients with early multiple sclerosis.

Multiple sclerosis (MS) is a chronic, debilitating disease characterized by multiple areas of focal demyelination that develop throughout the white matter of the central nervous system at varying times. Most patients report disequilibrium at some point in the course of their disease. When balance disturbance occurs early in the course of the disease prior to diagnosis, the patient may present to the otolaryngologist for evaluation. Are there any patterns of balance dysfunction that might suggest the diagnosis to the evaluating physician? An evaluation of ten patients with known early MS suggests that platform posturography and ENG is the test most likely to provide useful diagnostic information in patients with early MS.
