Sleep Modulation to Treat Depression
NCT06443216
Summary
Current first-line treatments for major depression (antidepressants and psychotherapy) show a long latency to response, and less than half of all patients experience full remission with optimized treatment, indicating the need for new developments. The aim of this study is to extend and further develop a longstanding line of research of using sleep neurophysiology as a 'window to the brain' and treatment development in major depression. Particularly, this project is designed to test the feasibility, efficacy and mechanisms of action of a new sleep-based treatment technology.
