We are inviting young people aged 16 to 25 years, with moderate-to-severe depression, to take part in this research. Participants will divided into two groups. One group will receive a low dose of ketamine once a week for four weeks. The other group will receive a low dose of another medication, called midazolam, once a week for four weeks.

We hope that the results of this study will help us to provide the best possible care in the future for young people with depression.
