根据阿尔茨海默氏症协会（2011年），（1）在美国（US），85岁及以上的人中有8人患有阿尔茨海默氏症，85岁及以上的人中约有一半患有阿尔茨海默氏症。有证据表明，患有阿尔茨海默病和相关痴呆症的司机不安全驾驶的风险增加。传感器、计算机和电信技术的最新进展提供了一种自动收集有关驾驶员（包括那些患有早期痴呆症的驾驶员）驾驶性能的详细、客观信息的方法。该项目的目的是使用车载技术来描述一组可能在早期痴呆症患者中常见的驾驶行为（即，诊断为记忆丧失），并将这些行为与一组没有认知障碍的驾驶员进行比较。17名被诊断为早期痴呆症的司机参加了这项研究，他们已经完成了全面的驾驶评估，并被允许驾驶。参与者的车辆装有一套传感器和数据采集系统，并像正常情况下一样驾驶1-2个月。使用研究团队开发的一套算法/算法对车载仪器的数据进行了简化和分析。来自早期痴呆组的数据与来自26名无痴呆症的老年驾驶员的现有数据集的类似数据进行了比较。研究发现，相对于对照组，早期痴呆组的驾驶空间明显受限。与此同时，早期痴呆症组（之前已被职业治疗师确认为安全驾驶）与对照组一样安全驾驶。两组都没有发现与安全相关的行为错误。两组人都很少出现寻路问题，但早期痴呆症组更容易迷路。(C)2011爱思唯尔有限公司保留所有权利。
According to the Alzheimer's Association (2011), (1) in 8 people age 65 and older, and about one-half of people age 85 and older, have Alzheimer's disease in the United States (US). There is evidence that drivers with Alzheimer's disease and related dementias are at an increased risk for unsafe driving. Recent advances in sensor, computer, and telecommunication technologies provide a method for automatically collecting detailed, objective information about the driving performance of drivers, including those with early stage dementia. The objective of this project was to use in-vehicle technology to describe a set of driving behaviors that may be common in individuals with early stage dementia (i.e., a diagnosis of memory loss) and compare these behaviors to a group of drivers without cognitive impairment. Seventeen drivers with a diagnosis of early stage dementia, who had completed a comprehensive driving assessment and were cleared to drive, participated in the study. Participants had their vehicles instrumented with a suite of sensors and a data acquisition system, and drove 1-2 months as they would under normal circumstances. Data from the in-vehicle instrumentation were reduced and analyzed, using a set of algorithms/heuristics developed by the research team. Data from the early stage dementia group were compared to similar data from an existing dataset of 26 older drivers without dementia. The early stage dementia group was found to have significantly restricted driving space relative to the comparison group. At the same time, the early stage dementia group (which had been previously cleared by an occupational therapist as safe to drive) drove as safely as the comparison group. Few safety-related behavioral errors were found for either group. Wayfinding problems were rare among both groups, but the early stage dementia group was significantly more likely to get lost.
