<p>Driver Self-Regulation Practices in Older Drivers with and Without Mild Cognitive Impairment</p>

Abstract

Objective: To assess the impact of cognitive, socio-demographic and driving-related characteristics on self-regulation practices in older drivers with mild cognitive impairment (MCI) (determined by the Telephone Cognitive Screen (T-CogS) score), compared with drivers with no cognitive impairment. Design, Setting, Participants: A cross-sectional study collected information from 362 drivers with MCI and 611 drivers with no cognitive impairment, who were aged 65+ years, and were living in Western Australia between November 2018 and February 2019. Measurements: Self-reported self-regulation driving practices. Results: The majority of drivers with MCI (62.4%) and those with no cognitive impairment (57.1%) reported self-regulating their driving in at least one situation, in the past three months. The most common situations that both groups of drivers self-regulated in were "driving at night in the rain", "parallel parking", and "driving when raining". Drivers with MCI were only significantly more likely to self-regulate when "making turns across oncoming traffic" and "driving at night". They also had 39% greater odds of self-regulating in at least one driving situation, compared with drivers with no cognitive impairment (OR: 1.39, 95% CI=1.04-1.85, p=0.02). Females also had 2.3 times greater odds of self-regulating (OR=2.34, 95% CI=1.76-3.12, p<0.001). Drivers aged 75+ years had 1.6 times greater odds of self-regulating, compared with drivers aged 65-69 years (OR=1.58, 95% CI=1.12-2.23, p=0.01). Conclusion: Older drivers with MCI were more likely to self-regulate their driving, compared to drivers with no cognitive impairment, particularly in complex driving situations. This suggests that some drivers with MCI may be able to recognize their cognitive limitations and adjust their driving accordingly. However, several drivers with MCI, particularly males, did not self-regulate their driving. This highlights the importance of advising patients about the impact of MCI on driving ability, suitable self-regulation strategies, as well as monitoring their driving ability.

Driving Performance and Its Correlation with Neuropsychological Tests in Senior Drivers with Cognitive Impairment in Japan

“…In our sample, younger people, males, and those with longer driving experience were more likely to be current drivers, in the light of demographic and driving-related characteristics. A similar pattern emerged in several previous studies [49][50][51]. As expected, current drivers performed better in neuropsychological testing than retired ones, which is in agreement with the findings of Vaughan et al [52].…”

Medications and risk of motor vehicle collision responsibility in British Columbia, Canada: a population-based case-control study

“…Drivers with minor impairment might minimise collision risk through selfregulation of their driving practices. 5 Hence, realworld epidemiological research is required to better quantify the collision risk associated with medication use. A comprehensive review of epidemiological research on this topic identified cohort designs comparing collisions in people taking medication versus those not taking medication, standard casecontrol designs comparing medication use in drivers involved in a collision with drivers who were not involved in a collision, and caseonly designs such as casecrossover studies and responsibility analyses.…”

The Impact of Cognition and Gender on Speeding Behaviour in Older Drivers with and without Suspected Mild Cognitive Impairment

“…Participants were recruited from the initial 1001 drivers who completed the first phase of the study (telephone interview). 26 Those who met eligibility requirements, expressed an interest and agreed to participate in the naturalistic driving phase of the study, were recruited between October 2019 and March 2020.…”

“…This cross-sectional naturalistic driving study examining speeding events in older drivers is part of a larger prospective cohort study examining the association between cognitive ability and driving. [26][27][28] Speeding events, which were measured using an in-vehicle monitoring device over a two-week period, were examined in 35 older drivers with suspected MCI, defined by the Montreal Cognitive Assessment (MoCA), and 36 older drivers with no cognitive impairment.…”
