AIM
Despite the recent upsurge of interest in mind wandering (i.e. the occurrence of task-unrelated and stimulus-independent thoughts), little research has attempted to evaluate mind wandering in Alzheimer's disease (AD). We addressed this issue by evaluating intentional and unintentional mind wandering, as well as the relationship between both mind-wandering domains. We also investigated the relationship between mind wandering and depression and working memory.
METHODS
A total of 30 participants with AD and 33 control participants participated in the study.
RESULTS
The results showed higher intentional and unintentional mind wandering in AD participants than in controls. In AD participants and controls, both mind wandering domains were significantly correlated with depression, but not with working memory.
CONCLUSIONS
The present findings show a tendency of AD patients to shift from external stimuli to task-unrelated thoughts and concerns, a tendency that seems to be related with depression. Geriatr Gerontol Int 2019; 19: 342-346.
目的
尽管最近人们对思维漫游（即任务无关和刺激独立的思维的出现）产生了浓厚的兴趣，但很少有研究试图评估阿尔茨海默病（AD）中的思维漫游。我们通过评估有意和无意的思维漫游，以及这两个思维领域之间的关系来解决这个问题。我们还研究了思维漫游与抑郁和工作记忆之间的关系。
方法
共有 30 名 AD 患者和 33 名对照组参与者参加了研究。
结果
结果表明，AD 患者的有意和无意思维漫游均高于对照组。在 AD 患者和对照组中，两个思维领域都与抑郁显著相关，但与工作记忆无关。
结论
本研究结果表明，AD 患者有从外部刺激转移到与任务无关的想法和担忧的趋势，这种趋势似乎与抑郁有关。老年医学与老年病学国际 2019；19：342-346。
