Research efforts to explore the etiological factors in Schizophrenia have identified the influence of season. Winter season appears to be associated with incidence of schizophrenia, it has been suggested that there is an excess of winter births among schizophrenic patients. There is need to explore the underlying mechanisms for excessive winter births among schizophrenic patients. A survey was carried out to find out the phenomenon of seaonality and its impact on schizophrenic incidence and it was found that majority of schizophrenic patients were born in winter season, thus suggesting a role of seasonality as a cuasal or precipitating factor in schizophrenia.
