Participate in our studies


Why do we need your participation?

In order to know more about Parkinson's disease (and other related neurological disorders) and how this affects not only movement skills, but also thinking abilities, emotion and learning we need your participation in our research. 

What are the benefits of participating in our research?

  1.  You will contribute to the develop more knowledge on Parkinson's disease and may thereby help others.
  2.  You will receive individual feedback about your performance during the computer tasks that measure thinking abilities.
  3.  Participation provides you with the opportunity to learn about cognitive changes in Parkinson's disease.

What can you expect?

  • Computer study

When you participate in a computer study, you will be asked to perform different tasks that measure thinking ability and reaction time. Tasks measuring reaction time will require you to make quick button presses with your left and right thumbs as you see objects appear on the computer screen. No computer experience is necessary to perform these tasks and rest breaks are provided frequently.

  • MRI study

For the Magnetic resonance imaging (MRI) study, you will be asked to lie still while being scanned in the magnet for about 40 minutes. The study does not required the use of injection.
