简要总结
The major objective of this proposal is to test the hypothesis that the addition of divalproex sodium to an atypical antipsychotic drug other than clozapine will significantly improve: a) cognition; and b) psychopathology (positive, negative, and mood symptoms) in a double-blind, randomized trial of 6 weeks duration in patients with schizophrenia or schizoaffective disorder.
详细描述
Cognitive function is one of the most critical deficits in schizophrenia and schizoaffective disorder. It has been found that cognitive dysfunction may be even more important than positive or negative symptoms in predicting functional outcomes such as community adjustment, ability to work, social interactions, and caretaker burden. Preclinical data from our laboratory provided the rationale for a clinical trial to test whether divalproex sodium ER can improve cognitive impairment in patients.

主要结局
Change in Cognition and Psychopathology Disorders as Measured on the MATRICS Consensus Cognitive Battery (MCCB)
时间窗: six weeks
Giving Divalproex Sodium ER to Outpatients with Schizophrenia and Schizoaffective Disorder in addition to taking Atypical Antipsychotic Drug has shown to change their cognition and psychopathology. The MCCB measures cognitive function. The MCCB provides an overall composite score, expressed as a T-score, with a mean of 50 and a standard deviation of 10 The MCCB does not have minimum and maximum scores due to the use of T scores. A typical score will fall within a range of 40-60. Scores below 40 indicate impaired cognitive functioning, while scores above 60 suggest above-average cognitive abilities. The MCCB is often used in clinical research to assess cognitive deficits in individuals with psychiatric disorders, and the T-score scale is used to track cognitive changes over time.
