It is so frustrating to have depression that won’t budge even after seeking help. You take antidepressants, go to therapy, put the work in, follow your providers’ treatment plans, and yet, you still feel awful. Sure, maybe your depression symptoms have improved slightly, but the heaviness never completely lifts.
Maybe you’ve gone even further. You’ve tried one medication after another, only to deal with multiple rounds of unpleasant side effects with little meaningful positive change. Or perhaps your treatment plan works for a while, but then your symptoms always end up returning again and again.
If you’re deep in this disheartening cycle, it’s normal to start wondering:
“OK, what now?”
“Why am I still depressed?”
“I’m doing everything right, why don’t I feel better yet?”
“Is this just how things are now? Will I ever feel better?”
This is what it’s like to experience treatment-resistant depression or TRD, depression that doesn’t respond adequately to multiple evidence-based treatment attempts.
You’re not crazy. But you may have heard the phrase, “the definition of insanity is doing the same thing over and over and expecting different results each time.” You’ll know when it’s time to break out of the negative feedback loop.
For many people with TRD, the first step towards freedom simply means accepting that it’s time to try something different. This often takes the form of a question you, yourself may be asking: “When is it time to change course completely and try something different?”
What Is Treatment-Resistant Depression (or TRD, for short)?
Treatment-Resistant Depression, or TRD, generally refers to major depressive disorder that has not improved sufficiently despite repeated treatment attempts.
There isn’t a single universally accepted definition of treatment resistance. When clinicians are determining what qualifies as “treatment resistance” they consider factors such as the type of treatment, dose, duration, adherence, and degree of improvement. In clinical practice, treatment-resistant depression is commonly considered after inadequate response to multiple adequate antidepressant trials.
If an antidepressant didn’t work because you stopped taking it after a week due to side effects, for example, that isn’t necessarily evidence that the medication was ineffective. A doctor is more likely to ask you to switch to another medication before they will label your depression as “treatment-resistant” in that case. Similarly, if a medication helped but didn’t completely eliminate symptoms, your provider may consider adjusting the dose, switching medications, adding another treatment, or combining approaches before concluding that the depression is resistant to treatment.
The VA/DoD clinical practice guideline for major depressive disorder recognizes the importance of reassessing treatment when depression persists and includes options such as medication strategies and transcranial magnetic stimulation (TMS) for people who have not responded adequately to previous treatments.
What Are the Signs of Treatment-Resistant Depression?
There isn’t a specific set of treatment-resistant depression symptoms that can tell you whether you have TRD. The underlying symptoms are generally identical to the symptoms of Major Depressive Disorder (MDD) itself.
MDD symptoms include:
- Persistent sadness, emptiness, or emotional numbness
- Loss of interest or pleasure in activities
- Fatigue or low energy
- Changes in sleep
- Changes in appetite or weight
- Difficulty concentrating or making decisions
- Feelings of guilt, worthlessness, or hopelessness
- Irritability or restlessness
- Social withdrawal
- Difficulty functioning at work, school, or home
- Thoughts of death or suicide
The National Institute of Mental Health explains that depression treatment commonly involves psychotherapy, medication, or a combination of the two. When these approaches don’t reduce symptoms sufficiently, brain stimulation therapies may be considered.
What makes depression potentially treatment-resistant is what happens after appropriate treatment is attempted. If you’ve consistently participated in treatment but continue to experience significant symptoms, it may be worth asking your provider whether your treatment plan needs to be reconsidered.

When Depression Isn’t Responding to Medication, What Should You Do?
Failed medication trails are a reason to reassess your treatment plan, but it’s never a reason to give up.
At Shanti TMS, our multidisciplinary team frequently considers TRD treatment options such as:
- Adjusting the current medication
- Switching to a different antidepressant
- Combining medications
- Adding another medication to an existing treatment
- Continuing or changing psychotherapy
- Addressing co-occurring conditions
- TMS, or Transcranial Magnetic Stimulation
The right approach depends on your individual history and medical circumstances. It is also heavily dependent on your personal preferences and treatment goals. Depression treatment is rarely one-size-fits-all, and finding an effective treatment that is a good fit for you, your body, and your lifestyle – well, that can involve some trial and error to really dial in.
Before Trying Something Completely Different, Reassess What You’ve Already Tried
One of the most important conversations to have with your provider is surprisingly simple:
“Have we really optimized the treatments I’ve already tried?”
A careful reassessment might look at:
Was the medication trial adequate? The dose and length of treatment matter when determining whether a medication has truly been ineffective. If you’re frequently skipping doses or mixing contraindicated medications together, then you haven’t really given that medication a chance to work.
Were there side effects that prevented you from continuing? A medication that you cannot tolerate isn’t necessarily evidence that every medication in the same category will fail. It’s possible a similar, but alternate medication will be a better fit for your body.
Have your symptoms changed? Depression can evolve over time. Your current symptoms may not be identical to those you experienced during an earlier episode.
Could another condition be affecting your response? Anxiety, substance use, sleep problems, chronic pain, trauma, and other medical or psychiatric conditions can complicate depression treatment.
Has psychotherapy been part of your treatment plan? For many people, medication and psychotherapy work together rather than serving as competing alternatives.
This kind of reassessment is especially important before deciding that you have “run out of options.”
You may simply have reached the point where the next treatment needs to work differently.
What Can You Do When Antidepressants Don’t Work?
When standard depression treatments haven’t provided enough relief, there are several possible paths forward.
Some people benefit from changing or augmenting medication. Others may benefit from a different psychotherapy approach or a combination of medication and therapy.
For people who continue to experience significant depression despite appropriate treatment, brain stimulation therapies can offer another category of treatment entirely.
The National Institute of Mental Health identifies repetitive transcranial magnetic stimulation (rTMS) as an FDA-authorized brain stimulation therapy for depression and explains that these treatments can be used when other approaches have not provided sufficient relief.
That doesn’t mean everyone with persistent depression needs TMS.
It means that TMS is an established treatment option worth discussing when conventional approaches haven’t been enough.
How TMS Fits Into Treatment-Resistant Depression Treatment
Transcranial magnetic stimulation uses magnetic pulses to stimulate specific areas of the brain involved in mood regulation. This safe, non-invasive, FDA-approved modality is one of the treatment options at Shanti TMS for people with treatment resistant depression at our SE Portland clinic.
Unlike an antidepressant, TMS does not circulate substances throughout the body. It’s also important to note that TMS has very little in common with “shock therapy,” or ECT. Unlike electroconvulsive therapy (ECT), TMS does not induce a seizure and does not require general anesthesia. There is no electrical current involved – just magnetic fields.
During a typical TMS session, an electromagnetic coil is positioned against the scalp. The device delivers repeated magnetic pulses to a targeted region of the brain.
The NIMH explains that rTMS can target specific brain sites and is performed without anesthesia. A typical course of conventional rTMS involves sessions five days a week for several weeks, although treatment schedules can vary depending on the protocol being used.
For someone who has spent years trying different medications, this difference can be significant.
TMS represents a different way of approaching depression, not simply another medication to add to the list.
At Shanti TMS in Portland, treatment is provided in an outpatient setting, allowing patients to remain awake during sessions and return to their normal activities afterward.
Does TMS Work for Treatment-Resistant Depression?
No depression treatment works for everyone, and TMS should not be presented as a guaranteed solution.
But the evidence supporting TMS for treatment-resistant depression is substantial enough that TMS has become an established treatment option for people seeking evidence-based care for TRD.
Case in point: the federal government is impressed enough with the results of TMS to include it as one of the official options for the treatment of TRD in veterans. In the process of updating their treatment guidelines for Depression, the VA reviewed the evidence for rTMS in treatment-resistant depression and concluded that the potential benefits of TMS – which sometimes include total symptom remission for TRD – outweigh the potential side effects.
Research into TMS is also continuing to evolve and uncover more evidence for to add to the existing body of evidence we have for the efficacy of TMS. For example, NIMH-funded researchers have been studying how brain connectivity can be used to make TMS targeting more precise. A 2024 NIMH research highlight described findings suggesting that stimulating surface brain regions connected to deeper areas involved in depression may influence those deeper circuits as well.
That research is part of a larger movement toward making depression treatment more personalized rather than assuming the same intervention will work equally well for everyone and attempting a “cookie cutter approach” to treatment planning.
What Does TMS Feel Like When You Have Treatment-Resistant Depression?
For many people, one of the biggest questions isn’t whether TMS works, it’s what actually happens when they sit down for treatment.
TMS is completely noninvasive. There is no surgery or needles or electrodes associated with TMS and it does not require any kind of anesthesia or prep on the patient’s part. Most patients are able to proceed directly from a TMS session at our clinic to their usual everyday activities – be it work, school, or caregiving.
During treatment, you may feel a tapping or clicking sensation on the scalp. Some people experience temporary scalp discomfort or a mild headache, particularly early in treatment. Serious complications are very uncommon, in part thanks to rigorous screening guidelines that ensure patients who are likely to have a negative response to TMS never receive TMS treatment in the first place. There are a conditions that make TMS an in appropriate choice for some patients and your provider will work with you to provide the appropriate medical screening before beginning TMS, as they would with any kind of treatment.
At Shanti TMS’s depression treatment program in Portland, patients always undergo a medical evaluation before treatment to determine whether TMS is appropriate for their individual situation.
When Is It Time for Treatment-Resistant Depression Patients to Try Something Different?
There isn’t a magic number of medications or a specific number of months that automatically means it’s time to move on.
But if you’ve been faithfully pursuing treatment and you’re still struggling to function, it is reasonable to ask whether continuing the same strategy makes sense.
Consider having a conversation with your provider if:
- You’ve tried multiple antidepressants without meaningful improvement.
- Side effects have made medications difficult to tolerate.
- You’ve participated consistently in psychotherapy but remain significantly depressed.
- Your symptoms continue to interfere with work, relationships, sleep, or daily life.
- You experience repeated symptomatic episodes despite treatment.
- You feel as though you’ve been cycling through the same approaches without making meaningful progress.
- You’re interested in exploring a medication-free treatment option.
The question doesn’t have to be, “Do I have treatment-resistant depression?”
A better starting point may be:
“Given everything I’ve tried, what other evidence-based options should I consider?”
Experiencing Treatment-Resistant Depression Doesn’t Mean You’ve Run Out of Treatment Options
Living with depression that hasn’t responded to treatment can create its own kind of hopelessness. After enough unsuccessful medication trials or disappointing treatment experiences, it is easy to start believing that nothing will work.
But treatment resistance is not the same thing as treatment impossibility.
Sometimes the next step is a medication adjustment. Sometimes it is a different therapy approach. And sometimes, after appropriate evaluation, it means considering a treatment that works through an entirely different mechanism.
The most important step isn’t necessarily deciding in advance whether TMS is your golden ticket to healing. It’s recognizing when the current approach isn’t providing enough relief and being willing to ask what comes next. TMS is one possible pathway forward, but only you know what the next best step is for your health. If depression treatment hasn’t worked the way you hoped, you haven’t necessarily reached the end of the road. You may simply be ready for a different path.
For people in Portland who have been struggling with depression despite conventional treatment, TMS for treatment-resistant depression at Shanti TMS offers an opportunity to explore whether this approach may be appropriate.
