痴呆症（PWD）患者经常会迷失方向，这增加了他们迷路的风险。本文探讨了在何种程度上，我们可以预测未来的行踪，通过学习他们过去的移动模式，使用全球定位系统（GPS）跟踪设备。7名老年痴呆症患者和8名健康老年人完成了为期8周的GPS数据收集。我们计算的概率，一个适当的算法可以正确地预测参与者的未来目的地使用空间和时间模式，在每个参与者的GPS轨迹。根据空间和时间模式，我们的研究结果表明，4周的移动模式记录显示痴呆组的潜在可预测性为95%，显著高于对照组的92%，t（13）=-3.39，P <0.01，d =-1.75。也就是说，我们可以希望能够预测PWD的目的地约95%的时间和控制的目的地约92%的时间。我们对残疾人流动模式可预测性的研究结果为预测流动模型提供了新的视角，这些模型可用于定位痴呆症失踪人员。
People with dementia (PWD) often become disoriented, which increases their risk of getting lost. This article explores the extent to which we can predict future whereabouts of PWD by learning from their past mobility patterns using Global Positioning System (GPS) tracking devices. Seven older adults with dementia and eight healthy older adults completed 8 weeks of GPS data collection. We computed the probability that an appropriate algorithm can correctly predict the participant's future destinations using spatial and temporal patterns in each participant's GPS trajectories. Relying on both spatial and temporal patterns, our results suggest that a 4‐week record of mobility patterns displays 95% potential predictability across the dementia group, which is significantly higher than 92% potential predictability among the controls, t(13) = –3.39, P < .01, d = –1.75. That is, we can hope to be able to predict destinations of PWD about 95% of the time and destinations of controls about 92% of the time. Our findings on predictability of mobility patterns among PWD offer new perspectives on predictive mobility models that can be used to locate missing persons with dementia.
