Abstract
This single case study describes the audiological and vestibular findings of a female patient, aged 62, with diabetes mellitus and rheumatoid arthritis. Based on this case study, we hypothesize that individuals with diabetes mellitus and rheumatoid arthritis are more vulnerable to vestibular impairment. The current findings indicate that central vestibular lesions and bilateral sensorineural hearing loss are related to rheumatoid arthritis and diabetes. Therefore concluding early detection and follow-up is required to understand pathophysiology in detail.
