OCD is a common mental health condition which makes people obsess over thoughts and develop behavior they struggle to control. You can even ask yourself,' Knutson said. 'Still, from a practical point of view it doesn't matter. The team notes a limitation of the research was that participants were only asked one question. It can cause people to have repetitive unwanted or unpleasant thoughts or to develop compulsive behavior  a physical action or something mental  which they do over and over to try to relieve the thoughts.
