To determine whether cognitive tests predict fitness to drive in patients with dementia.
Two group comparison of patients with dementia and healthy elderly volunteers, and comparison of patients with dementia who were found safe to drive and those found unsafe, followed by a validation study.
Forty-two people with dementia and 33 healthy elderly volunteers with no known memory problems who were driving. Of the 42 people with dementia 37 were assessed on the road. A second sample of 17 people with dementia was also assessed on the road.
Stroke Drivers Screening Assessment, Mini Mental State Examination, Salford Objective Recognition Test, Stroop Test, Test of Everyday Attention, Visual Object and Space Perception Battery, Behavioural Assessment of the Dysexecutive Syndrome, Adult Memory and Information Processing Battery.
All healthy elderly volunteers were safe to drive but 10 of the 27 patients with dementia were unsafe. Discriminant function analysis identified a combination of tests, which correctly classified 92% of drivers with dementia as safe or unsafe. Validation of this prediction on an independent sample had 59% accuracy using a cut-off of 0 but 88% accuracy using a cut-off of 5.
Safety to drive in people with dementia could be predicted from a combination of six cognitive tests. These correctly identified 67% of safe drivers in a validation sample. This assessment could be used to identify those who need evaluation of their safety on the road.
确定认知测试能否预测痴呆患者的驾驶适宜性。
对痴呆患者与健康老年志愿者进行两组比较，并对被判定驾驶安全和不安全的痴呆患者进行比较，随后进行一项验证研究。
42名痴呆患者和33名无已知记忆问题且正在驾车的健康老年志愿者。42名痴呆患者中有37名接受了道路评估。另一组17名痴呆患者样本也接受了道路评估。
中风驾驶员筛查评估、简易精神状态检查表、索尔福德客观认知测试、斯特鲁普测试、日常注意力测试、视觉物体与空间感知成套测验、执行功能障碍综合征行为评估、成人记忆与信息处理成套测验。
所有健康老年志愿者驾驶安全，但27名痴呆患者中有10名驾驶不安全。判别函数分析确定了一组测试组合，其将92%的痴呆驾驶员正确分类为安全或不安全。在一个独立样本上对该预测进行验证时，使用临界值0的准确率为59%，使用临界值5的准确率为88%。
通过六项认知测试的组合可以预测痴呆患者的驾驶安全性。这些测试在一个验证样本中正确识别了67%的安全驾驶员。该评估可用于识别那些需要进行道路安全评估的人。
