Objectives

Narrative objectives1

Broad cognitive domains are impaired in approximately 85% of patients with schizophrenia and cognitive deficits are considered to be a core feature of the disease. Cognitive impairments appear from early stage and have become an important therapeutic target for pharmacotherapy. The purpose of this study is to evaluate the effects of blonanserin and aripiprazole on cognitive function in antipsychotic-naive first-episode schizophrenia.
