Cognitive Effects Associated With Hippocampal Neurogenesis Induced by ECT in the Treatment of Depression
- Conditions
- Major Depressive Disorder (MDD)Bipolar Disorder Depression
- Registration Number
- NCT06661616
- Lead Sponsor
- Centre Hospitalier St Anne
- Brief Summary
Electroconvulsive therapy (ECT) is the treatment of choice for drug-resistant depression (30% of patients), or when there is a short-term risk to the patient's life. Despite its robust efficacy and rapid onset of action, its use is limited both by the limited range of treatment available and by the cognitive effects sometimes induced. The present study focuses on the links between the efficacy of ECT, its cognitive effects and the formation of new neurons in the hippocampus (hippocampal neurogenesis) associated with this treatment.
