Ketamine Alcohol (in Treatment-Resistant Depression)

ClinConnect Summary

This clinical trial is exploring how effective a single dose of ketamine, a medication known for its rapid antidepressant effects, can be in treating people who have major depression and have not found relief with standard treatments. The researchers are particularly interested in how a family history of alcohol use disorder might influence the way patients respond to ketamine. They aim to understand whether those with a family background of alcohol issues experience stronger antidepressant effects compared to those without such a history.

To participate, individuals must be between 18 and 55 years old and currently experiencing a major depressive episode lasting at least two weeks. They should also have tried at least one antidepressant in the past without success. Participants will receive a ketamine infusion during a specialized brain scan to measure changes in brain chemistry related to depression. It’s important to note that those with certain medical conditions, current substance use disorders, or a history of specific psychiatric disorders may not be eligible. Overall, this study hopes to gather valuable information that could lead to more personalized and effective treatments for depression in the future.
