[The Relationship of Deficit Syndrome with Clinical Symptoms, Summer Births and Heritability in Patients with Schizophrenia].
AIM: The aim of this study was to compare deficit schizophrenia patients with non-deficit schizophrenia patients for negative and positive symptome scores, rate of summer births, and rate of familial history of psychosis.
METHOD: 110 patients with schizophrenia diagnosed via Structured Clinical Interview for DSM-IV (SCID-I) aged between 18-65 were included in the study. All the patients were evaluated using the Scale for the Assessment of Negative Symptoms (SANS), Scale for the Assessment of Positive Symptoms (SAPS), and The Schedule for the Deficit Syndrome (SDS), and sociodemographic information was obtained.
RESULTS: The deficit syndrome group had higher negative and positive scores compared to the non-deficit group. The rate of summer births were higher in the deficit group. Although the rate of positive family history for psychosis was higher in deficit group compared with the non-deficit group, the difference did not achieve statistical significance.
CONCLUSION: Our results that depict higher severity of negative and positive symptom scores and higher rate of summer births with deficit schizophrenia, provides more evidence that deficit and non-deficit schizophrenia are different subtypes having different pathophysiologies. But statistically nonsignificant difference of positive familial history between two groups suggests that the thesis of deficit schizophrenia may be related to genetic factors more than enviromental factors needs to be invesigated further.
