Electronystagmography Outcome and Neuropsychological Findings in Tinnitus Patients

Author(s): Magdalena Jozefowicz-Korczynska, Elzbieta Agata Ciechomska and Anna Maria Pajor

Because psychological aspects often are underscored in the generation of tinnitus, we assessed the neuropsychological status in our group of patients. We found an increased number of abnormal electronystagmography (ENG) recordings in tinnitus patients. The aim of this study was to compare the ENG outcome with the patients' neuropsychological status. We carried out the study on 69 subjects complaining of tinnitus and on 43 healthy persons. We performed clinical neurootological examinations and ENG tests on all patients. Neuropsychological evaluation was conducted by means of the Beck Depression Inventory (BDI), the Hospital Anxiety and Depression (HAD) test, the Mini Mental Status (MMS) test, and the TrailMaking Test (TMT). In 46 patients (66.6%), we found abnormal ENG outcomes (central, 42%; peripheral, 13.0%; mixed, 1l.6%). Neuropsychological tests revealed abnormal scores: for the BDl, 43.5% of patients; for the HAD-A, 72.5%; for the HAD-D, 47.8%; for the MMS, 27.5%; and forthe TMT, 55.1 %. We did not find correlation between the ENG outcomes and neuropsychological test scores. We did not find correlation between the overall ENG outcomes and neuropsychological test scores, with one exception; we found the occurrence of abnormal neuropsychological test scores and the ENG outcome indicating central vestibular dysfunction. Our study showed that despite a high frequency of vestibular system dysfunction signs and a high incidence of abnormal neuropsychological test scores in tinnitus patients, only one correlation existed between these two results.
