Alteration of Functional Connectivity before and after Electroconvulsive Therapy in a Single Patient with Depression and Catatonia.

Catatonia, a severe neuropsychiatric condition, is distinguished by a range of prominent motor features such as immobility, mutism, negativism, rigidity, posturing, staring, stereotypy, automatic obedience, echolalia, and mannerism. A female patient of middle age was admitted to the open psychiatric ward of a hospital after exhibiting suicidal ideation, delusions, depression, insomnia, refusal to eat, difficulty in swallowing, and decreased motivation for four months prior to admission. Following 14 electroconvulsive therapy (ECT) sessions, her symptoms improved in the order of appetite, immobility, speech volume, mood, and delusions. The post-ECT functional connectivity was found to be improved compared to pre-ECT. The patient was discharged to outpatient clinics with medications that included aripiprazole, mirtazapine, quetiapine, and trazodone. This case reveals that ECT is an efficacious treatment in a depressive patient with catatonia, with movement symptoms responding to ECT more rapidly than affective symptoms. In addition to the improvement of movement and affective symptoms, functional connectivity much improved after ECT.
