Understanding Treatment-Resistant Depression
Nicholas Bowen, M.D.
Most people with depression improve with a combination of psychotherapy, medication, lifestyle interventions, or time. However, some individuals continue to experience significant symptoms despite appropriate treatment.
This is often referred to as treatment-resistant depression, generally defined as depression that has not responded adequately to at least two antidepressants taken at appropriate doses and durations.
Treatment resistance does not mean depression is untreatable. It simply means that standard treatments have not produced the desired response.
When depression persists, it’s important to step back and reconsider the entire clinical picture. Factors such as bipolar disorder, thyroid disease, sleep apnea, ADHD, trauma, substance use, chronic inflammation, medication interactions, and metabolic health may all influence treatment response.
Additional treatment options—including medication optimization, augmentation strategies, psychotherapy, neuromodulation, and ketamine—may then be considered.
Final Thoughts
Treatment-resistant depression is not the end of the road. It is often the beginning of a more comprehensive and individualized approach to care.
