About

Objectives:The purpose of the study is to explore the efficacy and safety of H1-Coil deep brain rTMS in subjects with negative symptoms and cognitive deficits of schizophrenia (deficit syndrome), currently treated with atypical antipsychotics.

Patient Population: The intention is to treat 45 patients diagnosed with schizophrenia, who are currently suffering mainly from negative symptoms and cognitive deficits (deficit syndrome). The patients will be of all racial, ethnic and gender categories, ranging from 18 to 65 years of age, and have PANSS negative≥21 and PANSS positive<24. Patients will be recruited from both academic and private research centers.

Structure: The study is a randomized, prospective, 8 weeks, double blind study. Blinding: The treatment administrator and the study personnel and patients will be masked to the treatment being administrated.

Concurrent Control: The study group will receive active rTMS treatment and the control group will receive an inactive, sham treatment.

Enrollment: 45 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers
