The schizo-obsessive spectrum. About a clinical case.

Introduction: The coexistence of psychotic symptoms and obsessive-compulsive symptoms (OCS) has been known since the 19th century, with a high prevalence of bothOCS (25%) and obsessive compulsive disorder (OCD) (12%) in patients with schizophrenia. Objectives: The main objective is to assess the validity of the schizoobsessive disorder as a diagnostic entity for those patients who show symptoms of schizophrenia and OCD. Methods: We present the case of a 61-year-old male with a diagnosis of schizophrenia from the age of 28 and obsessive-compulsive symptoms in the last 5 years. Results: The patient has important negative symptomatology, with ideoaffective impoverishment, short speech, abulia, motor slowing, poor social skills, abandonment of self-care, tendency to isolation, obsessive thoughts and compulsions of doubt and verification. He describes the presence of magical thinking, having to leave the doors opened, with the fear of bad things happening instead, he washes hands ten times a day to get rid of the negative energy of the objects, leaves the shoes in the room always in the same way and in the same place to prevent something bad from happening. He also maintains a delusional ideation of unstructured, chronic damage, without behavioral repercussion. Complementary tests (blood test and cranial CT) were normal. Conclusions: The differential diagnosis is made between schizoobsessive disorder and comorbid schizophrenia with OCD. He is being treated with clozapine, which has shown an exacerbation of obsessive symptoms, which is why amisulpride and sertraline are added. The schizo-obsessive disorder has clinical, neurobiological and neurocognitive features distinct from both schizophrenia and OCD. [ABSTRACT FROM AUTHOR]
