Diagnosis of Alzheimer's dementia and vehicle driving restriction: a scoping review.

There are doubts about vehicle driving restriction for patients with Alzheimer's disease. A scoping review was carried out using the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis Protocols (PRISMA‐ScR) methodology. Relevant databases were searched for articles published between 2000 and 2022 in English, Spanish, or Portuguese. Articles were included if they specifically addressed driving, risk of accidents, permission or licence to drive a motor vehicle in a context of important cognitive decline, or if addressed traffic legislation on driving and dementia. Twenty‐three articles were selected for full reading, six of which were observational studies and only one with an interventionist method. All articles were carried out in high‐income countries such as the UK, the US, and Australia. As a conclusion, there is no psychometric test in the literature sensitive enough to assess vehicle driving competence in older adults with cognitive deficits. Based on selected studies, there is no robust evidence to make recommendation for or against the cessation of vehicular driving for patients with mild cognitive decline or with mild dementia. In some situations, vehicle driving cessation can impact patients and their families. In addition, legal regulations regarding vehicle driving for older adults and people with dementia are scarce worldwide. Despite the scarcity of studies addressing the theme of vehicle driving in the context of dementia, there is some level of consensual reasoning that patients with moderate to severe dementia should halt driving activities, but the same does not apply for patients with mild levels of cognitive impairment, including mild dementia.
