The concept of pseudo-obsessive schizophrenia has been often used in the past. Clinically, severe obsessive-compulsive disorders (OCD) are closed from psychotic symptoms and ask questions about differential diagnosis with schizophrenia. Moreover some characterized schizophrenia may present in some cases obsessive compulsive symptoms (OCS).
