Scale for the Assessment of Negative Symptoms (SANS) [ Time Frame: Every 4 weeks over a 12 week period ]
Scores on the subscales are combined (summed) to compute a total score. There are a total of 17 subscales. Each subscale ranges from 0="Not at all" to 5="Severe". Every 4 weeks the summed subscale scores provide a total score for that week (0-85). These total scores from each week are then combined (summed) for an overall score and then averaged for the two groups after the 12 week period.

Rasagiline in the Treatment of Persistent Negative Symptoms of Schizophrenia
Rasagiline in the Treatment of Persistent Negative Symptoms of Schizophrenia
This is a study of a new medication for the treatment of cognitive impairments (thinking difficulties) and negative symptoms in people with schizophrenia. The new medication is rasagiline. Rasagiline is a drug which has been approved by the Food and Drug Administration for the treatment of Parkinson's disease. It is used to treat cognitive problems.
The study will consist of two phases: a 4-week continued stability phase (lead-in phase) and a 12-week double-blind treatment phase. In the lead-in phase, subjects receiving antipsychotic medication, who manifest moderate to severe and persistent negative symptoms, will remain on their maintenance regimen for at least four weeks. The treatment phase will be a 12-week, parallel groups, double-blind, placebo-controlled trial of adjunctive rasagiline (1 mg/day), a selective MAO-B oxidase inhibitor.
