Tinnitus has been implied as a "soft" sign of neurodegenerative disease, which is characterized by progressive loss of neuronal function, such as Alzheimer's disease (AD) and Parkinson's disease (PD). This study aimed to determine whether the risk of developing AD/PD increases after having tinnitus. We conducted a retrospective matched cohort study with 12,657 tinnitus patients and 25,314 controls from the National Health Insurance Research Database (NHIRD) in Taiwan with almost 10 years follow-up. Tinnitus-related risk on developing AD/PD followingly was determined by the Cox regression to identify potential confounding factors. Through the 10-year follow-up period, 398 individuals with tinnitus (3.1%) and 501 control individuals (2.0%) developed AD (P < 0.001), and 211 tinnitus patients (1.7%) and 249 control patients (1.0%) developed PD (P < 0.001). Compared with controls, patients with tinnitus were 1.54 times more likely to develop AD (95% confidence interval (CI) 1.34–1.78, P < 0.001) and 1.56 times more likely to develop PD (95% CI 1.29–1.89, P < 0.001), after adjusting confounding factors. Our results indicate an association between tinnitus and higher risk of developing AD and PD. Additional physical comorbidities may also increase the risk of developing AD and PD.

Background: The comorbidity of depression with anxiety disorders is associated with poorer treatment outcomes, worse quality of life, poorer adherence to treatment, and greater suicide risk in cancer patients. Objective: To assess the risk of comorbid anxiety and depressive disorders after the diagnosis of esophageal cancer compared with a matched cohort by using the Taiwan National Health Insurance Research Database (NHIRD). Methods: We conducted a retrospective study of 28,454 patients (14,227 patients with esophageal cancer and 14,227 matched patients) who were selected from the NHIRD. Patients were observed for a maximum of 12 years to determine the incidence of new-onset anxiety and depressive disorders for which antidepressants had been prescribed. A Cox regression analysis was performed to identify the risk factors associated with anxiety and depressive disorders in esophageal cancer patients. Results: The cumulative incidence of anxiety and depressive disorders in the esophageal cancer patients was significantly higher than that in the matched cohort ( P < .001). The adjusted hazard ratio (HR) was 2.24 (95 % confidence interval, CI = 1.95-2.56, P < .001) in the esophageal cancer cohort compared with the matched cohort. Independent risk factors for developing anxiety and depressive disorders among the patients with esophageal cancer included cirrhosis, cerebrovascular disease, and surgical treatment. Conclusion: Esophageal cancer may be a prominent risk factor for anxiety and depressive disorders. Based on our data, we suggest that attention should be focused on esophageal cancer patients with comorbid cirrhosis and cerebrovascular disease and those who have received surgical interventions.
