Stopped: Change in operative and administrative functions
Electroconvulsive therapy (ECT) is an established treatment for medication-resistant schizophrenia. There is debate about the best method of electrode placement. Bitemporal (BT) placement is commonly used for schizophrenia, while right unilateral (RUL) placement in mood disorders is associated with fewer adverse effects on memory and language. This study compares the efficacy, safety and cognitive effects of BT-ECT versus RUL-ECT in hospitalized schizophrenia patients with acute psychosis. Main Question: Does RUL-ECT reduce psychotic symptoms with fewer cognitive effects versus BT-ECT in patients with severe schizophrenia? Hypothesis: RUL-ECT is as effective as BT-ECT in reducing psychotic symptoms with fewer cognitive effects. Methods: Randomized trial in patients with schizophrenia (confirmed by DSM 5 criteria) and severe symptoms (PANSS score ≥60). Patients were assigned to receive BT-ECT or RUL-ECT. Efficacy was measured by a ≥30% reduction in symptom severity on the PANSS scale and overall improvement measured with the Clinical Global Impression scale. Cognitive function was assessed with the Montreal Cognitive Assessment (MoCA) and Brief Assessment of Cognition in Schizophrenia (BACS) scales.
