Schizoaffective disorder and schizophrenia: Clinical differences - 08/07/17
Résumé |
Introduction |
Schizoaffective disorder (SAD) and schizophrenia (SZ) are important causes of disability and morbidity. Finding clinical features that can help in their early differentiation may lead to a better understanding of these two nosologic entities.
Objectives |
The purpose of this study was to find clinical differences between SAD and SZ.
Methods |
We selected for this study 83 inpatients from the Timisoara Psychiatric Clinic, diagnosed with either SAD (n=35) or SZ (n=48), according to ICD-10 criteria. The research was conducted between 2014 and 2016. Socio-demographic (age, sex, education, marital status) and clinical data were analysed. The Brief Psychiatric Rating Scale (BPRS) was used to assess symptom severity.
Results |
Delusions of grandiosity were found significantly more frequent in SAD patients (P=0.001). By contrast, bizzare delusions (P=0.025), derealization phenomena (P=0.03) and negative symptoms (P=0.003) appeared more frequent in schizophrenic patients. We found no significant differences between the two samples regarding onset age, number of episodes, duration of episode, duration of remission and suicidal thoughts/attempts. Although the SZ sample had higher BPRS total scores than SAD patients, the differences were not statistically significant.
Conclusions |
Even though SAD and SZ are very similar in respect to their clinical presentation, this study also revealed certain differences that may enhance specific knowledge regarding these two disorders.
