NCT00482001

Brief Summary

The goal of the study is to assess the role of cholinesterase inhibitors in affecting the driving ability of cognitively intact seniors using driving simulators. We hypothesize that the use of a cholinesterase inhibitor for two weeks will be associated with improvement in safe driving behavior on a simulated driving task.

Outcome Measures

Primary Outcomes (7)

  • Psychomotor Vigilance Test (PVT)

    A measure of reaction time in milliseconds, using a handheld unit, in which participants respond to a visual simulus

    Day 15

  • Attention Network Test (ANT)

    A measure of reaction time in milliseconds, based on the speed with which participants press a key in response to a visual stimulus

    Day 15

  • Speed Deviation

    A measure of deviation from posted speed limit, measured in km/h

    Day 15

  • Deviation From Road Position

    A measure of deviation from central road position, measured in cm

    Day 15

  • Reaction Time to Wind Gusts

    Reaction time to wind gusts, measured in seconds

    Day 15

  • Percentage of Time in Safe Zone

    Time spent in safe zone (within 10km/h of speed limit and within 0.838m of centre of driving lane), measured as %

    Day 15

  • Collisions

    Number of collisions (on driving simulator)

    Day 15
