Background: Previous studies have demonstrated spatial cognitive deficits in patients with bilateral vestibulopathy (BVP). However, BVP patients frequently present with a concomitant sensorineural hearing loss, which is a well-established risk factor of cognitive impairment and incident dementia. Nonetheless, previous research on spatial cognitive deficits in BVP patients have not taken hearing status into account. Objective: This study aims to compare spatial cognition of BVP patients with healthy controls, with analyses adjusting for hearing status. Methods: Spatial cognition was assessed in 64 BVP patients and 46 healthy controls (HC) by use of the Virtual Morris Water Task (VMWT). All statistical analyses were adjusted for hearing (dys)function, sex, age, education, and computer use. Results: Overall, patients with BVP performed worse on all outcome measures of the VMWT. However, these differences between BVP patients and healthy controls were not statistically significant. Nonetheless, a statistically significant link between sensorineural hearing loss and spatial cognition was observed. The worse the hearing, the longer subjects took to reach the hidden platform in the VMWT. Furthermore, the worse the hearing, the less time was spent by the subjects in the correct platform quadrant during the probe trial of the VMWT. Conclusion: In this study, no difference was found regarding spatial cognition between BVP patients and healthy controls. However, a statistically significant link was observed between sensorineural hearing loss and spatial cognition.

虚拟莫里斯水任务在64例双侧性眼动病患者中的作用及听觉状态的影响。

背景:先前的研究表明双侧前庭病(BVP)患者的空间认知功能障碍。但是,BVP患者经常伴有感觉神经性听力损失,这是公认的认知障碍和突发性痴呆的危险因素。尽管如此,先前有关BVP患者空间认知缺陷的研究并未考虑听力状态。目的:本研究旨在比较具有健康对照的BVP患者的空间认知能力,并针对听觉状态进行分析调整。方法:通过使用虚拟莫里斯水任务(VMWT)评估了64位BVP患者和46位健康对照(HC)的空间认知。所有统计分析均针对听觉(功能障碍),性别,年龄,学历和计算机使用情况进行了调整。结果:总体而言,BVP患者在VMWT的所有结局指标上均较差。但是,BVP患者和健康对照者之间的这些差异在统计学上并不显着。尽管如此,仍观察到感觉神经性听力损失与空间认知之间的统计学显着联系。听觉越差,受试者越长才能到达VMWT中的隐藏平台。此外,听力越差,在VMWT的探查试验中,受试者在正确的平台象限中花费的时间就越少。结论:在这项研究中,BVP患者和健康对照组之间在空间认知方面没有发现差异。然而,在感觉神经性听力损失和空间认知之间观察到统计学上的显着联系。BVP患者和健康对照者之间的这些差异在统计学上无统计学意义。尽管如此,仍观察到感觉神经性听力损失与空间认知之间的统计学显着联系。听觉越差,受试者越长才能到达VMWT中的隐藏平台。此外,听力越差,在VMWT的探查试验中,受试者在正确的平台象限中花费的时间就越少。结论:在这项研究中,BVP患者和健康对照组之间在空间认知方面没有发现差异。然而,在感觉神经性听力损失和空间认知之间观察到统计学上的显着联系。BVP患者和健康对照者之间的这些差异在统计学上无统计学意义。尽管如此,仍观察到感觉神经性听力损失与空间认知之间的统计学显着联系。听觉越差,受试者越长才能到达VMWT中的隐藏平台。此外,听力越差,在VMWT的探查试验中,受试者在正确的平台象限中花费的时间就越少。结论:在这项研究中,BVP患者和健康对照组之间在空间认知方面没有发现差异。然而,在感觉神经性听力损失和空间认知之间观察到统计学上的显着联系。到达VMWT中隐藏平台所需的时间更长。此外,听力越差,在VMWT的探查试验中,受试者在正确的平台象限中花费的时间就越少。结论:在这项研究中,BVP患者和健康对照组之间在空间认知方面没有发现差异。然而,在感觉神经性听力损失和空间认知之间观察到统计学上的显着联系。到达VMWT中隐藏平台所需的时间更长。此外,听力越差,在VMWT的探查试验中,受试者在正确的平台象限中花费的时间就越少。结论:在这项研究中,BVP患者和健康对照组之间在空间认知方面没有发现差异。然而,在感觉神经性听力损失和空间认知之间观察到统计学上的显着联系。
