Abstract
Objectives. The study aimed to assess the relationship of tinnitus with hyperacusis with cognitive impairment as indicatedby the Montreal Cognitive Assessment (MoCA) tool.

Methods. This multicenter cross-sectional study included individuals with chronic tinnitus from the ¡°Unification of Treat-
ments and Interventions for Tinnitus Patients¡± (UNITI) database. Participants were recruited from four different ter-tiary clinical centers located in Athens and Granada (Mediterranean group), as well as Berlin and Regensburg (Ger-man group). In total, 380 individuals with a diagnosis of non-pulsatile chronic tinnitus (permanent and constant tin-nitus lasting more than 6 months) and no evidence of severe cognitive impairment (MoCA score >22) were enrolled.
The evaluation utilized the following tools: MoCA, Tinnitus Handicap Inventory (THI), Hyperacusis Questionnaire(GUF), Patient Health Questionnaire (PHQ-9), and the European School for Interdisciplinary Tinnitus ResearchScreening Questionnaire.

Results. MoCA scores differed between German and Mediterranean individuals (P <0.01), necessitating separate analysesfor each group. In both cohorts, MoCA scores were significantly associated with education level, age, hearing thresh-old at 8 kHz, and THI. Furthermore, a significant correlation was observed between PHQ-9 scores and both THI andGUF (P <0.01 for both Germans and those from the Mediterranean).

Conclusion. Our data suggest an association between tinnitus handicap, high-frequency hearing loss, and mild cognitiveimpairment. Additionally, PHQ-9 scores were associated with tinnitus and hyperacusis scores, independent of hear-ing loss thresholds.
