Brain wave test may predict ketamine success for severe depression

This study looks at whether specific brain wave patterns (gamma oscillations) can help predict how well ketamine therapy works for people with treatment-resistant depression. Researchers will measure brain activity using EEG before and during ketamine treatment and track depression symptoms over four weeks. The goal is to find a simple brain-based marker that could guide personalized treatment decisions for those who haven't benefited from other antidepressants.
