Targeted treatment options for treatment-resistant depression.
Learn what treatment-resistant depression means, how clinicians evaluate persistent symptoms, and which treatment approaches may be considered when standard treatments have not provided enough improvement.
- Common TRD definition
- Evaluation & reassessment
- Treatment approaches
A commonly used definition of treatment-resistant depression involves inadequate response to at least two adequate antidepressant trials, although definitions vary across clinical and research settings.
Definitions varyOptions can include medication changes or augmentation, psychotherapy, rTMS, esketamine, and ECT, depending on clinical circumstances.
Clinician-guided selectionThe length and frequency of treatment depend on the approach used, the person’s response, and the treatment plan developed with a clinician.
Individualized planningDepression that resists medication is not a failure of willpower
Treatment-resistant depression (TRD) generally refers to major depressive disorder that has not improved adequately after appropriate trials of antidepressant treatment. A commonly used definition involves inadequate response to at least two antidepressants given at adequate doses and for an adequate duration, with appropriate adherence. However, there is no single universally accepted definition of TRD.
Before depression is considered treatment-resistant, clinicians may reassess the diagnosis, medication dose and duration, adherence, side effects, co-occurring conditions, substance use, medical contributors, and other factors that can affect treatment response.
Common Features of Treatment-Resistant Depression
Symptoms can vary widely and may overlap with other forms of depression. Clinicians consider the full clinical picture and treatment history when evaluating possible TRD.
Persistent Depressive Symptoms
Symptoms may continue despite appropriate treatment attempts.
Loss of Interest or Pleasure
Anhedonia can remain prominent even when other symptoms change.
Sleep or Energy Changes
Sleep disruption, fatigue, or reduced energy may persist.
Cognitive Symptoms
Difficulty concentrating, slowed thinking, or problems with decision-making can occur.
Functional Impairment
Depression may continue to interfere with work, relationships, school, or daily activities.
Ongoing Emotional Symptoms
Low mood, hopelessness, guilt, or other depressive symptoms may remain clinically significant.
Clinical note: These features are not specific to TRD. A clinician evaluates the full clinical picture and treatment history when determining whether depression may be treatment-resistant.
Common Treatment Approaches
Options may include medication strategies, psychotherapy, and specialized treatments. The appropriate approach depends on clinical circumstances.
rTMS
A noninvasive brain-stimulation treatment using magnetic pulses to target specific brain regions. Courses involve repeated sessions over several weeks.
Explore rTMSEsketamine (Spravato®)
An FDA-approved option for adults with TRD, administered under healthcare-provider supervision with monitoring after each treatment session.
Explore esketamineMedication Optimization
Clinicians may adjust, switch, or augment medications based on response, side effects, treatment history, and individual clinical factors.
Explore medication optionsPsychotherapy
Psychotherapy may be continued, changed, or combined with medication when symptoms persist or response to treatment is incomplete.
Explore psychotherapyECT
A brain-stimulation treatment used for severe or treatment-resistant depression, especially when a rapid response may be needed.
Explore ECTClinical Trials
Research studies may provide access to investigational treatments that are still being evaluated for safety and effectiveness.
Explore clinical trialsUnderstanding the TRD Evaluation & Treatment Path
Evaluation and treatment planning for persistent depression can involve several stages. The exact approach varies by person and by the clinician or clinic providing care.
Review Treatment History
Clinicians review previous medications, doses, duration, adherence, benefits, side effects, psychotherapy, and other treatments.
Reassess the Clinical Picture
The evaluation may consider diagnosis, co-occurring conditions, medical contributors, substance use, and factors that can affect treatment response.
Discuss Treatment Options
Depending on the clinical situation, options may include medication strategies, psychotherapy, rTMS, esketamine, ECT, or other approaches.
Monitor Response & Adjust
Symptoms, functioning, side effects, and safety are monitored over time so treatment can be continued, changed, or adjusted as appropriate.

Frequently Asked Questions
Educational answers about treatment-resistant depression, evaluation, and commonly discussed treatment approaches.
How does TMS therapy differ from electroconvulsive therapy (ECT)?
TMS uses repeated magnetic pulses and does not intentionally induce a seizure. ECT uses a controlled electrical stimulus to induce a therapeutic seizure under anesthesia. ECT is generally used for more severe depression or when a rapid response may be needed, while rTMS is a noninvasive option commonly used for depression that has not responded adequately to medication.
Do I need to stop taking my current antidepressants to start TMS?
Not necessarily. Medication is often continued during rTMS, but the approach depends on the treatment plan and the specific medications involved. People should not stop or change antidepressants without guidance from their prescribing clinician.
How long does relief last after completing an intensive treatment course?
The duration of benefit varies. Some people maintain improvement while others experience a return of symptoms over time. Follow-up care and maintenance strategies depend on the treatment used and the individual’s response.
What if my insurance denies prior authorization?
Coverage and prior-authorization requirements vary by insurer, treatment, plan, and location. A clinic or treating clinician can explain the documentation required and whether an appeal or other coverage pathway may be available.
How is treatment-resistant depression diagnosed?
There is no single universal definition of TRD. A commonly used clinical definition involves inadequate response to at least two adequate antidepressant trials. Clinicians also review diagnosis, treatment adherence, dose and duration, co-occurring conditions, and other factors that may affect response.
Is ECT used for treatment-resistant depression?
Yes. ECT is an established treatment for severe depression and may be considered when depression has not responded to other treatments. It can also be considered when a rapid response is needed in certain severe or life-threatening situations.
