Cognitive Decline and Older Driver Crash Risk

Sleep duration, cognitive decline, and dementia risk in older women.

INTRODUCTION Consistent evidence linking habitual sleep duration with risks of mild cognitive impairment (MCI) and dementia is lacking. METHODS We conducted a prospective study on 7444 community-dwelling women (aged 65-80 y) with self-reported sleep duration, within the Women's Health Initiative Memory Study in 1995-2008. Incident MCI/dementia cases were ascertained by validated protocols. Co...

Evidence and Dimensions of Commercial Driver Differential Crash Risk

This paper highlights evidence from several instrumented vehicle studies that crash risk varies significantly among commercial truck drivers, and also cites findings from surveys of fleet safety managers and other experts on the topic of individual differences in commercial driver crash risk. Within various subject groups, 10-15% of the drivers typically account for 30-50% of the crash risk. Th...

The Effect of Cognitive Impairment on Older Pedestrian Behaviour and Crash Risk

Pedestrians are an extremely vulnerable road user group and make up approximately 15 percent of all road fatalities and 12 percent of all serious injuries. A large proportion of pedestrian deaths and serious injuries involve older adults, who are more vulnerable because of age-related frailty. Given that many crashes involving older road users occur in complex situations, it is suggested that a...

Predicting cognitive decline in healthy older adults.

OBJECTIVE Authors performed a neuropsychological determination of which individuals in a group of community-dwelling, healthy elderly volunteers would develop cognitive decline. METHODS A group of 155 volunteers reporting good memory and thinking participated in a prospective study over 4 years. Authors monitored cognitive functioning and incidence of Mild Cognitive Impairment (MCI)/Alzheimer...
