### Summary box #### What are the new findings? #### How might it impact on healthcare in the future? 115.4 million individuals are projected to live with dementia by 2050.1 Notably, there is consensus that a substantial proportion of dementia cases may be preventable.2 Therefore, identifying individuals exhibiting cognitive impairment in conjunction with dementia risk factors could improve intervention and reduce disease burden.3 Existing smartphone-based assessment tools have demonstrated validity in cognitive screening, however, none combine cognitive screening with risk factor assessment and few have the accessible design necessary for unsupervised use at home.4 5 Mindset4Dementia is a new smartphone-based application seeking to address this gap by integrating both cognitive screening and risk factor identification. The application can be completed unsupervised at home and takes only 5 min to complete. The user is guided through a conversational interface where risk factors are identified and cognitive screening is assessed via a modified Stroop and Symbol digit modality test.6 7 Poor performance on the Stroop and Symbol Digit Modalities (SMT) tests is linked with dementia and mild cognitive impairment (MCI).7–9 Studies suggest that Stroop (among other tests) is able to distinguish between patients with dementia and normal controls.8 9 The SMT is well suited for distinguishing between people with either MCI and dementia versus normal ageing7 and …

Mindset4Dementia 应用程序的初步验证研究：评估远程收集痴呆症风险因素和认知表现

### 摘要框#### 有哪些新发现？#### 它对未来的医疗保健有何影响？到 2050 年，预计将有 1.154 亿人患有痴呆症。1 值得注意的是，人们一致认为，很大一部分痴呆症病例可能是可以预防的。2 因此，识别表现出认知障碍和痴呆症风险因素的个人可以改善干预并减轻疾病负担。 3现有的基于智能手机的评估工具已经证明在认知筛查中是有效的，但是，没有一个将认知筛查与风险因素评估结合起来，而且很少有在家中无人监督使用所需的无障碍设计。4 5 Mindset4Dementia 是一种基于智能手机的新应用程序，旨在解决这个问题通过整合认知筛查和风险因素识别来实现差距。该申请可以在无人监督的情况下在家中完成，只需 5 分钟即可完成。用户通过对话界面进行引导，在该界面中识别风险因素并通过修改后的 Stroop 和 Symbol 数字模态测试评估认知筛查。6 7 Stroop 和 Symbol 数字模态 (SMT) 测试表现不佳与痴呆和轻度认知有关损伤 (MCI)。7-9 研究表明，Stroop（以及其他测试）能够区分痴呆患者和正常对照。8 9 SMT 非常适合区分患有 MCI 和痴呆的人与正常衰老 7 和……
