ECT & Depression: 34% Lower Suicide Risk – Review
Electroconvulsive therapy (ECT) dramatically lowers suicide risk for individuals battling severe depression, as revealed by a new meta-analysis. The study found a 34% reduction in suicide risk for patients undergoing ECT, compared to standard treatments. this research, examining data from over 43,000 individuals, also highlights a meaningful 30% decrease in overall mortality. ECT appears to offer broader health benefits, perhaps extending beyond mental health treatment.News Directory 3 brings you this crucial update, emphasizing the importance of ECT for treatment-resistant depression. Discover what’s next regarding neurostimulation techniques and their impact on suicidal behavior.
ECT Effective in Reducing Suicide Risk in Severe Depression
Updated June 13, 2025
Electroconvulsive therapy (ECT) considerably reduces suicide risk among individuals with severe depression, according to a new meta-analysis published in Neuroscience Applied. The study found that patients receiving ECT were 34% less likely to die by suicide compared to those treated with standard alternatives, such as antidepressant medication.
The research, conducted by scientists at the University Psychiatric Clinics Basel in switzerland, also indicated a 30% reduction in deaths from any cause for patients undergoing ECT, suggesting broader health benefits.The analysis pooled data from multiple high-quality studies, encompassing over 43,000 individuals.

Major Depressive Disorder (MDD) affects approximately 300 million peopel globally, a number that continues to rise.suicide, often linked to depression and mood disorders, is a leading cause of death worldwide, especially among young people.
The study focused on individuals with treatment-resistant depression, who do not respond to conventional treatments like selective serotonin reuptake inhibitors (SSRIs). Researchers examined the impact of three neurostimulation techniques: ECT, repetitive Transcranial Magnetic Stimulation (rTMS), and Vagus Nerve Stimulation (VNS), on suicidal behavior.
While the data for rTMS were inconclusive, and VNS showed potential but limited evidence, ECT demonstrated a clear and significant reduction in both suicide risk and overall mortality.
“To our knowledge, this is the first Meta-Analysis to demonstrate a survival benefit of ECT for individuals with depression,” said lead researcher Dr. Timur Liwinski.”Recent studies confirm that ECT remains the most effective treatment available for severe depression. Our work shows that suicide and all-cause mortality are also reduced.”
Dr. Liwinski also noted that more recent studies suggest even greater benefits from ECT, possibly due to advancements in the treatment’s methodology over time.
“We observed that newer studies tended to report greater benefits from ECT than older ones,” Liwinski said. “since our analysis spans many decades,it’s likely that today’s ECT offers even stronger protection against suicide than the 34% reduction we identified overall.”
Professor Martin balslev Jørgensen, who was not involved in the study, commented on the findings, stating, “This valuable study is critically important as, even though the effect of ECT on suicidality is well known among clinicians, it is indeed helpful to have it so clearly documented.”
What’s next
Further research is needed to explore the mechanisms behind ECT’s life-extending effects and to gather more robust data on the effectiveness of rTMS and VNS in reducing suicide risk among individuals with severe depression.
