Artemisinin With Risperidone for First-Episode and Drug-Naive Schizophrenia
A Double-Blind, Randomized, Placebo-Controlled Trial of Artemisinin as an Add-on Therapy to Risperidone in the Treatment of Drug-Naive First-Episode Patients With Schizophrenia
This study will determine the effectiveness of artemisinin plus risperidone in improving symptoms and cognitive disturbances and in Chinese people with schizophrenia. The study addresses the Toxoplasma infection hypothesis of schizophrenia.
Evidences of high levels of Toxoplasma gondii antibodies in the serum and the cerebrospinal fluid (CSF) of individuals with schizophrenia have suggested that this organism might be involved in the etiopathogenesis of schizophrenia. The investigators hypothesize that antimicrobial therapy by using an add-on agent together with a well-proven neuroleptic may have favorable effects on a subgroup of schizophrenic patients.
