The driving performance of individuals with mild cognitive impairment (MCI) is suboptimal when compared to healthy older adults. It is expected that the driving will worsen with the progression of the cognitive decline and thus, whether or not these individuals should continue to drive is a matter of debate. The aim of the study was to provide support to the claim that individuals with MCI can benefit from a training program and improve their overall driving performance in a driving simulator. Fifteen older drivers with MCI participated in five training sessions in a simulator (over a 21-day period) and in a 6-month recall session. During training, they received automated auditory feedback on their performance when an error was noted about various maneuvers known to be suboptimal in MCI individuals (for instance, weaving, omitting to indicate a lane change, to verify a blind spot, or to engage in a visual search before crossing an intersection). The number of errors was compiled for eight different maneuvers for all sessions. For the initial five sessions, a gradual and significant decrease in the number of errors was observed, indicating learning and safer driving. The level of performance, however, was not maintained at the 6-month recall session. Nevertheless, the initial learning observed opens up possibilities to undertake more regular interventions to maintain driving skills and safe driving in MCI individuals.
与健康的老年人相比，轻度认知障碍（MCI）患者的驾驶表现欠佳。预计随着认知能力下降的进展，他们的驾驶能力会恶化，因此，这些人是否应该继续开车是一个有争议的问题。该研究的目的是支持这样一种说法，即MCI患者可以从培训项目中受益，并在驾驶模拟器中提高他们的整体驾驶表现。15名患有MCI的老年驾驶员参加了在模拟器中的五次培训课程（为期21天）以及为期6个月的回访课程。在培训期间，当他们在进行各种已知MCI患者表现欠佳的操作（例如，摇摆行驶、不打转向灯变道、不查看盲点或在通过十字路口前不进行视觉搜索）出现错误时，会收到关于其表现的自动听觉反馈。对所有课程的八种不同操作的错误数量进行了统计。在最初的五次课程中，观察到错误数量逐渐且显著减少，表明学习效果良好且驾驶更安全。然而，在6个月的回访课程中，表现水平并未维持。尽管如此，最初观察到的学习效果为采取更常规的干预措施以维持MCI患者的驾驶技能和安全驾驶开辟了可能性。
