Effects of Insomnia on Simulated Driving (MK-0000-183-00)

This is a double-blind, parallel design study in elderly primary insomnia patients and
demographically matched controls. The objectives if this study are primarily: 1. To
determine if functional deficits in simulated driving performance can be demonstrated in
primary insomnia patients, and detected in healthy volunteers, impaired by alcohol; and
secondarily: 2. To compare simulated driving performance deficits in elderly primary
insomnia patients to those in healthy elderly volunteers impaired by alcohol, for at least
one of the following driving endpoints: standard deviation of lane position (SDLP), standard
deviation of speed (speed deviation), lane excursions, and a driving composite score.
