A small number of patients are suffering from more than one psychiatric disorder at the same time, known as overlap syndrome. One form is OCD with anxiety. In this disorder, the fear of contamination is associated with the anxiety of phobias; an example might be an agoraphobic OCD patient who is afraid that he might be sick or die if he wanders into a public restroom. Another patient might have social anxiety and OCD that cause him to be afraid of public speaking.
