- ECT shows 51-53% complete recovery rates. A 2012 review of 1,106 patients found that over half with depression or bipolar disorder fully recovered after ECT.
- ECT works fastest for severe depression. When rapid symptom relief is critical, such as with suicidal patients, ECT acts faster than medication or therapy.
- Treatment-resistant depression responds well. Many patients who haven't improved with multiple medication trials find success with ECT.
- Modern ECT is safer than historical versions. Today's ECT uses anesthesia and muscle relaxants, making it much gentler than outdated depictions suggest.
- Memory side effects remain a concern. Short-term memory issues are common, and some patients experience longer-lasting memory problems.
- ECT requires ongoing maintenance. Many patients need continuation treatment after the initial course to prevent relapse.
