Project summary
Driving is a complex activity requiring a multitude of cognitive skills and abilities. For persons with dementia (PWD) cognitive impairment affects their ability to engage with activities of daily living; driving inevitably becomes difficult and they may become unsafe on roads.
Defective eye scanning (inadequate scanning, loss of central field advantage affecting response times etc) has been shown to be an early feature in the prodromal phases of dementia called mild cognitive impairment.
A decline in visual scanning skills, which help drivers judge risk and predict upcoming traffic problems, could play a large role in making people with early dementia unsafe drivers. For example, small changes in visual scanning may reduce reaction times and/or result in failure to notice important cues.
Loughborough University, in collaboration with the Monash University Accident Research Centre, aims to investigate the sensitivity and specificity of non-invasive eye scanning on driving ability in older people with and without early dementia/MCI, comparing it against usual dementia screening tests.
Using a novel ‘walking and talking’ technique the project will also explore the needs and preferences of people with cognitive impairment who are no longer able to drive safely with regard to feedback mechanisms they would like to have (voice over, automated vehicle derived actions etc).
