5. Study Description
Brief Summary
The primary purpose of this study is to determine the effects of methylphenidate versus placebo on driving ability of adult ADHD patients.
Detailed Description
This study was set-up to examine the controversial issue whether or not it is safe to drive a car or not when treated with methylphenidate.
On-the-road driving tests during normal traffic are conducted to determine the effects of methylphenidate versus placebo on driving ability of adult ADHD patients.In addition, two laboratory tests are conducted to examine memory functioning and inhibitory control.
