A retrospective chart review of 56 Veterans who completed a program combining sublingual ketamine therapy with a transdiagnostic intensive outpatient program (IOP) found significant reductions in symptoms of depression, anxiety, and posttraumatic stress, along with improved quality of life. Clinically meaningful improvements were most notable among those with moderate to severe baseline symptoms. The intervention is thought to enhance neuroplasticity and emotional learning while increasing treatment engagement and long-term resiliency. The lack of a control group limits the findings, and further research is needed to validate the results and adapt the model for Veterans.
