Schizophrenia is a severely disabling brain disorder. People with schizophrenia often experience hallucinations, delusions, thought disorders, and movement disorders. Proper treatment of first-episode schizophrenia may increase the chances of controlling disease progression on a long-term basis. People experiencing their first episode of schizophrenia are more responsive to treatment than those with chronic schizophrenia, but are also more susceptible to adverse treatment side effects. Atypical antipsychotic medications have been shown to produce fewer extrapyramidal side effects than older "typical" antipsychotics. Oral risperidone is an atypical antipsychotic medication that is very commonly used to control the symptoms of schizophrenia. Adherence to prescribed oral medication continues to be a major clinical issue. This study will determine the effectiveness of oral risperidone versus a long-acting injectible alternative, paliperidone palmitate, in treating people with first-episode schizophrenia. Impact on clinical symptoms and cognitive functioning will be examined.
