A recent study has raised doubts about the effectiveness of Ketamine as a potential treatment for Depression. Researchers discovered that individuals with depression who received either saline or ketamine prior to undergoing anesthesia for surgery exhibited comparable outcomes. This finding challenges the previous notion that ketamine might have significant benefits for individuals battling depression. While ketamine has shown promise in some studies, this research highlights the need for further investigation into its efficacy and raises questions about its role as a primary treatment option for depression.
