Energy Homeostasis and Metabolism in Patients With Schizophrenic Disorders Under Treatment With Atypical Antipsychotics

The purpose of this study is to evaluate the effects of different atypical antipsychotics on weight changes, energy homeostasis, metabolism, energy intake as well as activity.

Patients with schizophrenia or schizoaffective disorders will be randomly assigned to be treated with ziprasidone or olanzapine for 24 weeks.
