The proposed study will be conducted to compare the efficacy of maintenance ECT (M-ECT) vs Clozapine in treatment resistant schizophrenia (TRS) in terms of change in psychopathology measures and cerebral hemodynamics.
The proposed study is a prospective, randomized clinical trial in patients suffering from treatment-resistant schizophrenia (TRS) and will be conducted in the Department of Psychiatry, AIIMS, Bhubaneswar, over a period of 16 months. Sixty patients with TRS (TRRIP consensus criteria, 2017), fulfilling the inclusion and exclusion criteria will be recruited for the study. Written informed consent will be taken after explaining the objectives and procedure of the study in detail. The detailed history, relevant social-demographic and clinical data will be collected in a structured case record form (CRF). At baseline, PANSS will be administered to determine the severity of positive symptoms, negative symptoms, and general psychopathology, Global assessment of functioning (GAF), and CGI to determine the baseline severity of the illness and improvement with treatment and MoCA to assess change in cognitive impairment. Before starting the treatment, brain SPECT-CT will be done to measure baseline regional brain blood perfusion. The study cohort will be randomized into two treatment groups by computer-generated random numbers, each group comprising 30 patients. One group will receive maintenance ECT (M-ECT) following acute treatment of bilateral ECT of six sessions along with ongoing antipsychotic and the other group will be treated with Clozapine monotherapy. PANSS, GAF, CGI, MoCA will be re-administered at 6 weeks, 3 months, and 6 months follow-up visits to compare the changes within each group and between the groups. Post-treatment SPECT-CT of the brain will be done at the end of 6 months to document changes in the regional cerebral blood perfusion.

Following acute treatment with bilateral ECT of 6 sessions over a period of two weeks, Bilateral M-ECT will be administered at a frequency of 1 session/week for one month, then 1 session / 2 weeks for 2 months and then 1 session/month for next 3 months.
Clozapine will be given in accordance with Maudsley guideline: 12.5 mg on the first day, followed by 12.5mg twice daily on the second day, followed by 25mg twice daily for next two days and then increment of 25mg every two days till the target dose of 250-400 mg per day in two divided doses as per tolerability of the patients

Change in severity of psychopathology
Severity will be assessed by Positive and Negative Symptom Scale (PANSS) PANSS Score ranges from 30- 210. A higher score represents more severe psychopathology
Time frame: 24 weeks
Change in illness severity, and global improvement with treatment
Assessed by change in Clinical Global Impression Schizophrenia (CGI-SCH) scores.
Time frame: 24 weeks
Change in global functionality
Assessed by change in Global assessment of functioning (GAF) scores.
Time frame: 24 weeks
Change in Cognitive impairment
Assessed by change in Montreal Cognitive Assessment (MoCA) scores.
Time frame: 24 weeks
Number of patients receiving rescue medications.
Patients with "treatment relapse" or "treatment non-response" will receive rescue medications.
Time frame: 24 weeks
Change in regional cerebral blood flow
Change in regional cerebral blood flow will be measured by SPECT-CT Brain
Time frame: 24 weeks
