Summary

Dopamine has been closely associated with prefrontal function. The hypothesis that a lower dopaminergic activity is associated with negative symptoms and cognitive dysfunction observed in the patients of schizophrenia is of a heuristic value in guiding research in this area. This hypothesis led us to test whether pergolide, a D1/D2 agonist, could improve negative symptoms and cognitive impairments prevailing in most patients with schizophrenia. This double-blind placebo controlled study will investigate the remedial effect of pergolide on negative symptoms and cognitive impairments in schizophrenia.
