Successful Resolution of Messianic Delusion following Bi-temporal Modified Electroconvulsive Therapy in a Patient with Treatment-resistant Schizophrenia

Messianic delusion comprises a delusional system centered on the patient’s conviction that he has been selected by God for a special task or mission and has unique abilities to carry it out. The present case report describes a case of Treatment-Resistant Schizophrenia (TRS) with Messianic delusion in a 23-year-old unmarried male who presented to the Emergency Department with complaints of muttering to himself, decreased sleep, suspiciousness, socio-occupational dysfunction, aggressive behaviour, and a recent suicide attempt. Key interventions offered during the ward stay included rapid tranquilisation, antipsychotics, and benzodiazepines. The patient completely recovered with the concurrent use of clozapine and Modified Electroconvulsive Therapy (MECT). The patient received 16 sessions of MECT. He achieved both short-term and long-term remission with the therapy, as observed during regular follow-ups in the next six months. The present case emphasises the need for a multidisciplinary approach to the management, early detection, and adequate treatment of this challenging illness.
