Driving practice effects for older drivers with mild cognitive impairment: A preliminary study

Research output: Contribution to journalArticlepeer-review


Background: Older drivers with mild cognitive impairment (MCI) often show declining driving performance. Evidence is lacking regarding whether their driving skills can be improved after practice. Aims/Objectives: To compare the practice effects of older drivers with MCI and drivers with normal cognition in an unfamiliar, standardized driving course with three practices. Materials and Methods: Single-blind two-group observational design. Twelve drivers with confirmed MCI as the experimental group and ten with normal cognition (NC) as the control, all ≥ 55 years old. The primary outcome was to assess the practice effects, measured with an in-car global-positioning-system mobile application to compare the speed and directional control of a complex manoeuvre after practices. Secondary outcomes were to assess the pass/fail rate and mistakes observed for the 3rd/final on-road driving practice. No instructions were given during practice. Descriptive statistics and the Mann–Whitney U test were used for data analysis. Results: No significant inter-group difference in the pass/fail rate and number of mistakes. Some MCI drivers performed better in the speed and directional control of the S-Bend manoeuvre after practices. Conclusions: The driving performance of drivers with MCI may improve with practice. Significance: Older drivers with MCI may potentially benefit from driver retraining. Clinical Trial Registration: ClinicalTrials.gov (Identifier: NCT04648735).
