The aim of this study was to explore the impact of sleep quality on cognitive function in patients with chronic subjective tinnitus.
The Pittsburgh Sleep Quality Index (PSQI) and the Montreal Cognitive Assessment Scale (MoCA) were used to assess sleep quality and cognitive function in patients with chronic subjective tinnitus, sleep disorder patients (SD), and normal controls (NC). The tinnitus evaluation questionnaire (TEQ) and tinnitus loudness were used to assess the severity in patients with chronic subjective tinnitus. Tinnitus patients were divided into two groups based on PSQI results: "tinnitus with sleep disorder (TwSD)" and "tinnitus without sleep disorder (TnSD)." The MoCA scores in TwSD and TnSD groups were compared with those in SD and NC groups, and the correlation between PSQI, TEQ, tinnitus loudness, and MoCA scores in subjective tinnitus patients were analyzed.
Whether TwSD group or TnSD group, the MoCA score was significantly lower than those in the NC group and SD group. Meanwhile, there was no significant difference between TwSD and TnSD groups in MoCA score, and PSQI, TEQ, and tinnitus loudness were not significantly correlated with MoCA.
Subjective tinnitus may be an independent risk factor for cognitive impairment. The underlying neural mechanisms between subjective tinnitus, sleep disorders, and cognitive impairment need to be further explored and clarified.
本研究旨在探讨睡眠质量对慢性主观性耳鸣患者认知功能的影响。
采用匹兹堡睡眠质量指数（PSQI）和蒙特利尔认知评估量表（MoCA）评估慢性主观性耳鸣患者、睡眠障碍患者（SD）和正常对照组（NC）的睡眠质量和认知功能。采用耳鸣评估问卷（TEQ）和耳鸣响度评估慢性主观性耳鸣患者的严重程度。根据 PSQI 结果将耳鸣患者分为“伴睡眠障碍的耳鸣（TwSD）”和“不伴睡眠障碍的耳鸣（TnSD）”两组。比较 TwSD 和 TnSD 组与 SD 和 NC 组的 MoCA 评分，并分析主观耳鸣患者 PSQI、TEQ、耳鸣响度与 MoCA 评分之间的相关性。
无论是 TwSD 组还是 TnSD 组，MoCA 评分均明显低于 NC 组和 SD 组。同时，TwSD 组和 TnSD 组的 MoCA 评分无显著差异，且 PSQI、TEQ 和耳鸣响度与 MoCA 评分均无显著相关性。
主观性耳鸣可能是认知障碍的独立危险因素。需要进一步探讨和阐明主观性耳鸣、睡眠障碍和认知障碍之间的潜在神经机制。
