This is an extension study to further test the efficacy and safety of asenapine compared with a marketed agent (olanzapine) in the treatment of patients with persistent negative symptoms of schizophrenia.

To investigate the 'estrogen-protection' hypothesis by comparing changes in psychotic symptoms between one group of patients receiving standard antipsychotic drug treatment plus placebo and a second matched group receiving standard antipsychotic drug treatment plus 100microgram estradiol patch in a double blind controlled trial. Hypothesis : That the women receiving adjunctive estradiol will demonstrate a more rapid and more substantial decrease in psychotic symptoms over the course of the study than the women receiving adjunctive placebo.

This study design is subject to relevant SFDA regulations about clinical trials. Patients will be screened for inclusion into the study at the initial visit(240 patients to be recruited) and then undergo a minimum of 3-7 day's placebo washout period(placebo wash out is to eliminate the effect of prior antipsychotic medication with tablets without any active ingredients)(patients without prior antipsychotic medication are exempt from the washout phase). After screening and washout period, eligible patients will be randomly assigned to the two treatment group, Aripiprazole or Risperidone, for 6 week's treatment. Patients will be hospitalized for the entire duration of the study. Patients' condition will be assessed weekly.

The primary purpose of this project is to evaluate the efficacy of a group therapy intervention, cognitive behavioral social skills training (CBSST), that teaches social functioning skills and cognitive-behavioral compensatory aids to older patients with schizophrenia. CBSST, therefore, targets the multidimensional deficits that lead to disability in aging veterans with severe mental illness.
