Commercial advertising of computerized "brain games" may result in clinicians being asked whether brain games prevent dementia. To address this question, we conducted a review of computerized cognitive training (CCT) interventions in older adults with Mild Cognitive Impairment (MCI). Studies were identified using a PubMed and PSYCinfo search for review articles. Within 11 review articles we identified 15 unique studies. Nine of these studies used commercially available "brain games" as their primary CCT intervention. Nine of 12 studies that examined the effect of CCT on episodic memory performance showed significant improvements in this domain. Furthermore, four of six studies that examined mood and or anxiety showed improvements in these domains following a CCT intervention. While more than double the amount of time was spent on the training that used commercially available "brain games" versus those designed by investigators, there were no differences in outcomes. Overall, it appears that "brain games" may modestly benefit aspects of cognition and aspects of mood in patients presenting with MCI. However, there is no direct evidence from the studies presented here that "brain games"/CCT can prevent dementia. We present recommendations to consider when discussing "brain games" with persons with MCI.
商业广告宣传的电脑化“大脑游戏”可能会导致临床医生被问到大脑游戏是否可以预防痴呆。为了解决这个问题，我们对轻度认知障碍（MCI）老年人的计算机认知训练（CCT）干预措施进行了综述。使用 PubMed 和 PSYCinfo 搜索综述文章来确定研究。在 11 篇综述文章中，我们确定了 15 项独特的研究。其中 9 项研究使用商业上可用的“大脑游戏”作为主要的 CCT 干预措施。在 12 项研究中，有 9 项研究检查了 CCT 对情景记忆表现的影响，显示出该领域的显著改善。此外，在进行 CCT 干预后，有 4 项研究中的 6 项研究检查了情绪和/或焦虑状况，显示出这些领域的改善。尽管使用商业上可用的“大脑游戏”进行训练的时间是使用研究人员设计的训练时间的两倍多，但结果没有差异。总体而言，“大脑游戏”似乎可以适度改善 MCI 患者的认知和情绪方面。然而，从这里呈现的研究中没有直接证据表明“大脑游戏”/CCT 可以预防痴呆。我们提出了一些建议，以便在与 MCI 患者讨论“大脑游戏”时考虑。
