Characteristics of a "nonspecific" ENG population

Fifty-one patients with "nonspecific" (nonlocalizing) electronystagmograms were studied both concurrently and retrospectively to determine the characteristics of this sample population. Data were gathered for the following categories: (1) vestibular signs/symptoms; (2) trauma; (3) aural signs/symptoms; (4) hearing loss; (5) psychosocial behavior; (6) other neurological findings; and (7) other medical problems. Analysis indicates that twice as many females have nonspecific electronystagmogram findings. The majority of these are in the menopausal age range. Most patients are uncertain about the onset, duration, and frequency of their vestibular problems. A high percentage of the population had a history of psychiatric treatment.
