The purpose of the study was to examine whether schizophrenia with obsessive-compulsive disorder (OCD) represents a severe form of OCD-spectrum disorders on the basis of neurological soft signs (NSS) and obsessive-compulsive (OC) symptoms. Sixteen patients with OCD-schizophrenia, 25 OCD patients and 23 healthy controls (HC) were studied. Scales for the Assessment of Positive (SAPS) and Negative Symptoms (SANS), Clinical Global Impressions Scale and Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) were used to assess the schizophrenic and OC symptomatology. NSS were evaluated with the Neurological Evaluation Scale (NES). OCD-schizophrenics had significantly higher scores on total NES than HC. The patients with OCD were more likely to have total Y-BOCS and subscale scores of compulsions than patients with OCD-schizophrenia. The rate of symmetry obsessions and cleaning/washing compulsions were significantly higher in patients with OCD compared to OCD-schizophrenics. We have found no correlation of OC symptoms with schizophrenic symptomatology. Our findings may suggest that OCD-schizophrenia is a distinct subtype of schizophrenia, not a more severe form of OCD-spectrum disorder.

A substantial proportion of adolescent schizophrenia patients exhibit obsessive-compulsive symptoms/disorder (OCS/OCD). In the present study we sought to provide a clinical characterization of adolescent schizo-obsessive patients. A consecutive sample of 22 adolescent patients (age 13-18 years) who met DSM-IV criteria for both schizophrenia and OCD was compared with 22 non-OCD schizophrenia patients matched for age, gender and number of hospitalizations. The Structured Clinical Interview for DSM-IV Axis I psychiatric disorders (SCID-I), the Scale for the Assessment of Positive (SAPS) and Negative (SANS) Symptoms, the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and the Clinical Global Impression (CGI) were used. We found that schizo-obsessive patients had earlier age at onset of schizophrenia symptoms, had more OCD spectrum disorders, primarily tic disorders, but did not differ in severity of schizophrenia symptoms from non-OCD schizophrenia patients. In a majority of the schizo-obsessive patients, OCS preceded or co-occurred with the onset of schizophrenia and did not correlate with schizophrenic symptoms. As expected, more schizo-obsessive patients than their non-OCD counterparts were treated with adjunctive anti-obsessive agents. These findings indicate that clinical characteristics of adolescent schizo-obsessive patients are generally similar to those previously revealed in their adult counterparts. The neurobiology underlying the co-occurrence of the OC and schizophrenia symptoms merits further evaluation.

A substantial proportion of schizophrenia patients also exhibit obsessive-compulsive symptoms (OCS). We sought to determine whether the revealed symptom dimensions in OCD exist in schizophrenia patients with comorbid OCD. One hundred and ten patients who met DSM-IV criteria for both schizophrenia and OCD were recruited. Exploratory factor analysis of the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) checklist was conducted. The inter-relationship between the resulting factors and schizophrenia symptom dimensions, as assessed by the Schedule for the Assessment of Positive (SAPS) and Negative (SANS) Symptoms, was examined. The principal component analysis of 13 Y-BOCS checklist categories yielded a five-factor solution and accounted for 58.7% of the total variance: (1) aggressive, sexual, religious obsessions and counting, (2) symmetry and ordering/hoarding compulsions, (3) contamination and cleaning, (4) somatic obsession and repeating compulsion, (5) hoarding obsession and checking/repeating compulsions. The Y-BOCS symptom dimensions did not correlate with schizophrenia symptom dimensions. The five symptom dimensions are comparable to those revealed in "pure" OCD, and suggest the involvement of universal mechanisms in the pathogenesis of OCD regardless of the presence of schizophrenia.
