About
Our overall aim is to determine if the administration of guanfacine in combination with aripiprazole, olanzapine, quetiapine, and/or risperidone is significantly more effective than any of those medications alone in treating some of the cognitive impairment in schizophrenia.
Full description
The proposed study is a double blind, placebo controlled, parallel designed investigation comparing the effect of one of four atypical antipsychotics (aripiprazole, olanzapine, quetiapine, and/or risperidone), treatment alone to treatment with one of these in addition to treatment with guanfacine to maximum dose of 3.0 mg per day on a cognitive task performance in schizophrenic patients. The study will take place over fourteen weeks. Patients will receive study medication for the last ten weeks of the protocol.
