More than just noise: Association of pulsatile tinnitus with anxiety, depression, and reduction of quality of life.

BackgroundWhile many of the causes of pulsatile tinnitus (PT) are treatable with endovascular approaches, the risks of treatment must be balanced with the risks of the underlying cause and the psychological impact of symptoms on patients. While many physicians have anecdotal experience, the comorbid relationship of depression and anxiety with PT is unknown. The objectives of this study are to quantify the prevalence of depression and anxiety, and, to identify the demographic risk factors for impactful depression and anxiety in patients with PT.MethodsSubjects recruited from online PT groups filled out secure online questionnaires that included demographic questions, validated Tinnitus Functional Index (TFI) as well as PHQ-9 and GAD-7 questionnaires to assess the prevalence of concurrent depression and anxiety, respectively.ResultsSample included 515 surveys (84% female, 65% unemployed, mean(sd) age = 46.4 years (14.2)). Median symptom duration was 1.9 years. Data showed 46% and 37% of patients with moderate to severe depression and anxiety, respectively. Higher TFI scores were associated with moderate to severe depression (OR 1.07; 95% CI 1.06-1.09, p < 0.001) and anxiety (OR 1.05, 95% CI 1.04-1.06, p < 0.001), with TFI subscores also independently being associated in a univariate analysis.ConclusionsThe prevalence of moderate to severe depression and anxiety in the PT population, which was previously unknown, is estimated in our study to be 46% and 37%, respectively. Significant association of TFI score with increased depression and anxiety scales adds further evidence of the impact of PT on the psychological health of these patients.
