Optimizing ECT for difficult-to-treat depression
Changing Tactics? Optimizing ECT in Difficult-to-treat Depression: A Randomized Trial Comparing Continuation of Right Unilateral ECT and Switching to Bitemporal ECT in Case of Early Non-response During an Acute Course of ECT for Difficult-to-treat Depression
This study is testing whether sticking with one type of electroconvulsive therapy or switching to another can help people with tough-to-treat depression recover faster and with less impact on their thinking.

What this trial studies
This randomized controlled trial aims to determine whether continuing with right unilateral (RUL) electroconvulsive therapy (ECT) or switching to bitemporal (BT) ECT is more effective in speeding up recovery and minimizing cognitive impact for patients with difficult-to-treat depression who show no early response to treatment. Participants will be assessed for antidepressant efficacy and cognitive performance during the acute ECT course and up to three months post-treatment. The study will involve patients diagnosed with major depressive disorder or bipolar disorder who have not responded adequately after four ECT sessions.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 and older diagnosed with major depressive disorder or bipolar disorder who have not shown a significant response to initial ECT treatments.
Not a fit: Patients with contraindications for general anesthesia, non-Dutch speakers, or those with certain psychiatric disorders such as schizophrenia will not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved treatment strategies for patients with difficult-to-treat depression, enhancing recovery rates while preserving cognitive function.
How similar studies have performed: Other studies have explored ECT techniques, but this specific comparison of RUL versus BT ECT in early non-responders is relatively novel.
