Summary

This study is a registry that will follow up to 1,000 adults with treatment-resistant depression or obsessive-compulsive disorder (OCD) who receive electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), or ketamine/esketamine. Researchers will collect data from brain scans, cognitive tests, voice recordings, and genetic tests before, during, and after treatment. The goal is to find biological markers that can predict which therapy works best for each person, moving toward personalized psychiatry.
