BACKGROUND/AIMS: To date, there are few studies on gender differences in patients with mild cognitive impairment (MCI) and Alzheimer disease (AD). In the present study, the existence of differences between sexes in verbal and visuospatial working memory tasks in the evolution of cognitive and pathological aging was examined.
Ninety participants took part in this study: 30 AD, 30 MCI, and 30 healthy elderly participants (50% men and 50% women).
There were no significant differences between men and women with AD in visuospatial tasks, whereas these differences were found within the MCI group, with the average of men achieving significantly higher results than women. In verbal tasks, there were no differences between sexes for any of the groups.
Execution in visuospatial tasks tends to depend on gender, whereas this does not occur for verbal tasks.
背景/目的:迄今为止,关于轻度认知障碍(MCI)和阿尔茨海默病(AD)患者性别差异的研究较少。在本研究中,我们检验了在认知和病理性衰老过程中,言语和视觉空间工作记忆任务中性别差异的存在情况。
90名参与者参与了本研究:30名AD患者、30名MCI患者和30名健康老年参与者(男性和女性各占50%)。
AD患者在视觉空间任务上男女之间无显著差异,而在MCI组中发现了这些差异,男性的平均成绩显著高于女性。在言语任务中,任何一组的男女之间均无差异。
视觉空间任务的执行往往取决于性别,而言语任务则不然。
