Zusammenfassung

Hintergrund

Depressive Störungen sind häufig und führen zu hohem individuellem Leiden sowie sozioökonomischen Kosten. Trotz verschiedener effektiver Therapieoptionen wird die Remission als Ziel der Behandlung oft nicht erreicht. Der Einsatz der Elektrokonvulsionstherapie (EKT) kann hier eine sinnvolle Option sein.

Ziel der Arbeit

Diese Arbeit stellt die aktuelle Evidenz zu Wirksamkeit, Sicherheit und Verträglichkeit der EKT bei depressiven Störungen dar.

Material und Methoden

Es wurde eine selektive Literaturrecherche unter besonderer Berücksichtigung von Metaanalysen, systematischen Reviews sowie Empfehlungen nationaler und internationaler Leitlinien durchgeführt.

Ergebnisse

EKT stellt ein wirksames und für die meisten Patienten sicheres und gut verträgliches Verfahren zur Therapie depressiver Störungen dar. Auch bei Pharmakotherapieresistenz finden sich noch relativ hohe Remissionsraten. Für bestimmte Populationen scheint eine besonders gute Wirksamkeit zu bestehen. Im Gegensatz zur gut belegten Wirksamkeit der Akuttherapie fehlen weitgehend belastbare Daten zur Erhaltungstherapie. Unerwünschte Wirkungen, insbesondere kognitive Störungen, sind in der Regel nur kurzfristig vorhanden. Modifikationen in der Durchführung haben Auswirkungen auf die Wirksamkeit und Verträglichkeit.

Diskussion

Mit der EKT steht ein bei korrekter Anwendung hochwirksames Therapieverfahren zur Behandlung depressiver Störungen zur Verfügung. Angesichts der Häufigkeit depressiver Störungen und einer vielfach nicht erreichten Remission wäre eine weitere Ausweitung der Verfügbarkeit und Anwendung der EKT genauso wünschenswert wie eine intensivierte, ggf. multizentrische Forschung zu den Wirkmechanismen und Responseprädiktoren der EKT.

Summary

Background

Depressive disorders are common and lead to both individual suffering and high socioeconomic costs. Despite the fact that several effective therapies are available, remission is often not achieved. Electroconvulsive therapy (ECT) can be a therapeutic option in these cases.

Objectives

This review outlines the current evidence for the efficacy, safety and tolerability of ECT for depressive disorders.

Material and methods

A selective literature search was carried out with particular consideration of meta-analyses, systematic reviews, and recommendations of national and international therapy guidelines.

Results

For the majority of patients ECT is an effective, safe and well-tolerated therapy for the treatment of depressive disorders. There are relatively high remission rates even in patients with pharmacoresistant depression. There is evidence for a particularly high responsiveness in specific populations. In contrast to the proven effectiveness in the acute treatment of depressive disorders, there is a relative lack of data concerning maintenance therapy. Side effects including cognitive deficits are mostly transient. Modifications in the ECT technique have an impact on effectiveness and tolerability.

Conclusion

When administered correctly ECT is a highly effective therapy for the treatment of depressive disorders. In the light of the abundance of depressive disorders and lack of remission despite adequate pharmacological treatment, a broader availability and application of ECT would be desirable. The same is true for a more intensive research into the mechanisms of action and response predictors of ECT.
