1.3 Special Considerations in Treating Pediatric Schizophrenia and BipolarI Disorder
Pediatric schizophrenia and bipolarI disorder are serious mental disorders; however, diagnosis can be challenging. For pediatric schizophrenia, symptom profiles can be variable, and for bipolarI disorder, pediatric patients may have variable patterns of periodicity of manic or mixed symptoms. It is recommended that medication therapy for pediatric schizophrenia and bipolarI disorder be initiated only after a thorough diagnostic evaluation has been performed and careful consideration given to the risks associated with medication treatment. Medication treatment for both pediatric schizophrenia and bipolarI disorder should be part of a total treatment program that often includes psychological, educational and social interventions.
