Dizziness is a common patient symptom and often remains medically unex
plained even after an extensive work-up. The otologic disorders, psych
iatric disorders, and functional disability of 75 patients presenting
with dizziness to a community otolaryngology practice were assessed in
1991. The patients were classified according to the presence or absen
ce of at least one current DSM-III-R psychiatric disorder and the pres
ence or absence of a peripheral vestibular disorder. Decrements in men
tal health and role functioning, and increases in bodily pain and hypo
chondriacal focus were significantly associated with the presence of a
psychiatric disorder and whether the etiology of dizziness was due to
a peripheral vestibular dysfunction.
