Observational Study to Evaluate Efficacy and Remission Status for Schizophrenia Patients Under Atypical Treatment

A Naturalistic Observational Study to Evaluate Efficacy of 2nd-generation Antipsychotics and Remission Status for Patients With Schizophrenia / Schizoaffective Disorder

The objective of this study is to evaluate under routine clinical setting the efficacy and remission status from treatment of 2nd-generation antipsychotic in patients who is upon acute episode or not achieving remission under regular treatment from schizophrenia/schizoaffective disorder.

Side effect of movement disorder will be evaluated by Drug Induced Extrapyramidal Symptoms Scale (DIEPSS). Tolerability for treatment will be monitored by documenting spontaneous reports on adverse events as well as change in body weight.
