| Purpose Recent literature suggests that tinnitus can impact cognition, but results were varied due to a diversity in investigated aspects of cognition and utilized tests, as well as the possible influence of confounding factors. The purpose of this study was to assess the impact of tinnitus loudness on cognition by use of a within-subjects design in patients with a cochlear implant (CI). In this population, tinnitus loudness can be modulated by switching the CI on or off as CI is known to highly suppress tinnitus. Methods A total of 18 CI users completed two versions of the Repeatable Battery for Assessment of Neuropsychological Status for Hearing Impaired individuals (RBANS-H), once in unaided condition and once in best aided condition. Tinnitus suppression was defined as a difference in score on a visual-analogue scale (VAS) of at least one point out of ten between these two conditions. Results No significant differences in RBANS-H scores were found between the suppression and no suppression group, nor for the suppression group alone. No significant correlations between tinnitus loudness and RBANS-H were found, neither for the suppression group alone, nor for the group as a whole. Conclusion The current study shows no significant effect of tinnitus loudness on cognition, which contradicts previous literature. This discrepancy could be explained by the use of a within-subjects design, which controls for confounding factors. Future research should include a larger and more diverse study sample to draw definitive conclusions on this topic. |
