Difference between ocd and paranoid delusions?

Anxiety v. psychosis: Ocd has two major components: intrusive and inappropriate thoughts (not worries about real-life problems), and repetitive behaviors aimed at preventing or reducing distress. With ocd, people recognize that the thoughts are creations of their own anxious minds. With paranoid delusions, people have fixed beliefs that they believe are actually true in the real world--even though they are false.
