Neurology :不食人间烟火真的好吗?对周遭事物不感兴趣的人更易患老年痴呆症

2020-10-22 生物世界 Bio生物世界

每个人都有自己独特的性格,有的人冲动活泼,而有的人则是沉稳冷静,两者各有优劣。实际上,虽然性格一经形成便比较稳定,但也并非是一成不变的,许多时候我们也可以通过有意识地改变在一定程度上重塑自己的性格。

每个人都有自己独特的性格,有的人冲动活泼,而有的人则是沉稳冷静,两者各有优劣。实际上,虽然性格一经形成便比较稳定,但也并非是一成不变的,许多时候我们也可以通过有意识地改变在一定程度上重塑自己的性格。

心理学研究表明,性格反映出一个人对现实的稳定态度,因此,性格更多的是影响着我们的人际关系。

然而,令人意外的是,10月14日一篇发表在 Neurology 杂志上的研究论文表明,性格冷漠的人患老年痴呆症的风险更大!

该研究由加州大学旧金山分校的Meredith A. Bock博士等人完成,文章题为:Apathyand risk of probable incident dementia among community-dwelling older adults。

不得不说的是,在现代社会,每个人的工作、学习和生活压力都大如山岳,这也使得许多人身心共疲而对周遭事物愈发漠不关心——有时候尽管时间很充裕,但却对很多东西都提不起兴趣。

阿尔茨海默症(Alzheimer's disease, AD),俗称“老年痴呆症”,是一类主要发生于老年人且以进行性认知功能障碍和行为损害为特征的中枢神经系统退行性病变。更重要的是,除了少数病例涉及基因突变外,阿尔茨海默症的病因尚不完全清楚。

随着世界人口老龄化形势也来越严峻,阿尔茨海默症的发病率也在不断攀升。那么,冷漠的性格态度与老年痴呆症的发生发展之间是否有着此前未被发现的联系呢?

在此项研究中,研究团队招募了2018名社区居住的老年志愿者进行了相关的问卷调查,并将冷漠与抑郁、焦虑区分开来。

修改后的冷漠评估量表的问题和回答选项

具体而言,冷漠的人往往对周围的世界缺乏兴趣,其表现包括停止参与正常活动、表现出很少的情感和缺乏活力等。研究人员更具问卷结果将这些志愿者分成低冷漠、中度冷漠和严重冷漠三组。

此外,研究小组通过一种基于痴呆症药物使用信息、医院记录以及临床相关的认知能力测定的算法来确定志愿者是否患上了痴呆症或是表现为记忆力和思维能力的显着下降。同时,研究人员还使用Cox比例风险模型其他因素进行调整修正,以此更好地验证冷漠与痴呆症之间联系。

不同程度的冷漠与老年痴呆症的联系

在长达9年的随访调查中,研究团队发现有381名志愿者可能患上了痴呆症。更重要的是,在未调整(HR 1.9, 95% CI 1.5-2.5)和调整模型(HR 1.7, 95%CI 1.3-2.2)中,与低冷漠相比,严重冷漠的志愿者更可能患上痴呆症(25%vs14%)。并且,研究人员还发现冷漠与记忆力和思维能力的下降有关,但与时间的变化率无关。

在Cox比例风险模型中,冷漠致痴呆症的风险

对此,英国阿尔茨海默病研究中心负责人SaraImarisio博士表示:“在痴呆症中,冷漠的症状很常见,但许多痴呆症患者被误诊为抑郁症,尤其是在早期阶段。因此,更好地了解一些不太为人所知的痴呆症症状,比如冷漠,将有助于我们开发更好的治疗方法!”

总而言之,这项近期发表的研究在一组社区成年人中发现,冷漠——即对周遭事物不感兴趣的人患上老年痴呆症的风险更大。同时,这项研究还为冷漠是痴呆的早期症状提供了新的证据。

不管怎么说,我们要时常对生活充满热情,如果你发现自己对周围世界越来越提不起兴趣时,那可要小心得老年痴呆症哦!
