From an evolutionary perspective it does as well, usually stress would entail danger so OCD like traits might really have helped our ancestors survive in situations like that.

Apparently it's linked to Neurogenesis as well, well that depression and schizophrenia. Stress can create chemicals that decrease the natural rate of Neurogenesis and it's been seen that SSRIs actually promote Neurogenesis and that if you give a patient(I think a patient but it might have been a mouse study) SSRIs yet at the same time you inhibit Neurogenesis then it does not cure depression, so it may be that is what causes it. Exercise also promotes Neurogenesis.
