Investigating brain effects of depression treatments using advanced imaging

The Neurobiological Fundaments of Depression and Its Relief Through Neurostimulation Treatments

Observational Haukeland University Hospital · NCT05135897

This study looks at how different depression treatments, like ECT and TMS, affect the brain using advanced imaging to see how well they work for people with major depressive disorder compared to healthy individuals.

What this trial studies

This observational study explores the neurobiological foundations of major depressive disorder by utilizing advanced magnetic resonance imaging (MRI) techniques. It aims to correlate imaging findings with psychiatric responses, neuropsychological functioning, and genetic biomarkers in patients undergoing electroconvulsive therapy (ECT) and repetitive transcranial magnetic stimulation (rTMS). The study includes three groups: patients receiving ECT, patients receiving TMS, and healthy controls, with assessments conducted at multiple time points over six months to document treatment effects and potential side effects.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with moderate to severe major depressive disorder who are eligible for ECT or TMS.

Not a fit: Patients with mild depression or those not meeting the diagnostic criteria for major depressive disorder may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of depression treatments and lead to improved therapeutic strategies.

How similar studies have performed: Other studies have shown promising results using similar neuroimaging approaches to understand the effects of depression treatments.
