All patients will receive supportive psychotherapy both during the hospitalization and in clinic follow-up. Discharged patients will be followed in the outpatient clinic of the Beersheba Mental Health Center by a physician plus dietician team dedicated to this study. Each patient will be followed for six months. Outcome measures will be BPRS ratings over the course of the half year, readmissions, Global Clinical Assessment of function at the end of the half year, and risperidone dose.
