When you have tried treatment for depression and still do not feel better, it can be discouraging. Some people wonder if they did something wrong, waited too long, or failed at treatment. In reality, limited response to depression treatment is a recognized clinical problem. It is not a personal failure.
In our practice, we often look at depression as part of a larger clinical picture. Symptoms may overlap with anxiety, trauma, bipolar disorder, ADHD, medical conditions, sleep problems, substance use, or other psychiatric concerns. Some people improve only partially. Others cannot tolerate certain medications. Some feel better for a while and then find that symptoms return.
When standard treatments have not provided enough relief, a careful psychiatric reevaluation can help clarify what may be contributing to ongoing symptoms and what options may be appropriate to discuss next.
What Is Treatment-Resistant Depression?
Treatment-resistant depression, often shortened to TRD, generally refers to depression that has not improved enough after adequate treatment attempts. There is no single universal definition of TRD, and definitions vary across research and clinical practice. However, many clinical discussions use the term when a person has not had adequate improvement after trying two or more antidepressant treatments at appropriate dose and duration.
A peer-reviewed review on current definitions of treatment-resistant depression notes that lack of a universal definition can make TRD difficult to study and compare across settings. That matters because “treatment-resistant” does not mean the same thing for every patient.
Most importantly, treatment-resistant depression does not mean depression is untreatable. It means previous treatments have not worked well enough, and the treatment plan may need to be reassessed.
Why Depression May Not Respond to Initial Treatment
There are many reasons depression may not improve as expected. Sometimes the first treatment is not the right fit. Sometimes the diagnosis needs to be revisited. Sometimes another condition is affecting the course of depression.
Factors that may contribute to limited treatment response include:
- An incomplete or evolving diagnosis
- Co-occurring anxiety, trauma, OCD, ADHD, bipolar disorder, or substance use
- Medical conditions that affect mood, energy, sleep, or concentration
- Medication side effects that make treatment difficult to continue
- A medication dose or duration that was not adequate for the person’s symptoms
- Sleep disruption, chronic stress, or major life strain
- Prior medication trials that helped only partially
- Individual differences in how people respond to treatment
The National Institute of Mental Health describes depression as a condition that can affect how a person feels, thinks, sleeps, eats, works, and handles daily activities. Because depression can touch so many areas of life, treatment response often depends on more than one factor.
Signs It May Be Time to Reevaluate the Treatment Plan
It may be time to discuss reevaluation when depression symptoms continue despite treatment, or when improvement is only partial and daily life is still affected.
A psychiatric reevaluation may be helpful if:
- Depression symptoms persist after medication or therapy
- Initial improvement has faded
- Symptoms continue to affect work, school, relationships, or self-care
- Side effects make medication hard to tolerate
- Several medications have been tried without enough benefit
- Anxiety, panic, trauma symptoms, OCD symptoms, attention concerns, or mood instability are also present
- Sleep problems, medical concerns, or substance use may be affecting symptoms
- Safety concerns or worsening symptoms emerge
Reevaluation does not mean starting over. It means taking a closer look at the full clinical picture and asking whether the current treatment plan still fits.
What a Psychiatric Evaluation May Review
A psychiatric evaluation for ongoing depression may include a careful review of symptoms, history, prior treatment response, and co-occurring concerns. The goal is to understand what has been tried, what helped, what did not help, and what may have been missed.
We may review:
- Current depression symptoms and severity
- How long symptoms have been present
- Prior diagnoses
- Medication history and response
- Side effects or tolerability concerns
- Therapy history
- Medical history
- Sleep, appetite, energy, and concentration
- Anxiety, trauma, OCD, ADHD, mood instability, or thought symptoms
- Substance use or alcohol use
- Daily functioning and safety concerns
For some patients, this process helps clarify that the current diagnosis is accurate but additional treatment options should be considered. For others, it may reveal that another condition is contributing to depression or complicating treatment response.
Treatment Options That May Be Discussed
Treatment-resistant depression does not have one single solution. The appropriate next step depends on the person’s diagnosis, prior treatment history, medical factors, preferences, and safety considerations.
Depending on the patient, we may discuss options such as:
- Adjusting the current medication
- Switching medications
- Combining medications when clinically appropriate
- Adding or continuing psychotherapy
- Addressing sleep, substance use, medical factors, or co-occurring symptoms
- Considering TMS when clinically appropriate
- Discussing off-label ketamine treatment when clinically appropriate
- Coordinating care with other clinicians involved in the patient’s treatment
No option is appropriate for everyone. The purpose of reevaluation is to identify which possibilities make sense for the individual patient.
TMS and Treatment-Resistant Depression
Transcranial magnetic stimulation, or TMS, is a noninvasive brain stimulation treatment that uses magnetic pulses to stimulate targeted areas of the brain. The National Institute of Mental Health describes repetitive TMS as an FDA-cleared treatment option for treatment-resistant depression. Unlike conventional antidepressants, which typically work through ongoing effects on neurotransmitter systems such as serotonin or norepinephrine, TMS acts more directly on brain circuits involved in mood regulation. Esketamine also differs from many traditional antidepressants because it acts primarily through the glutamate system, rather than the serotonin-based pathways targeted by many commonly prescribed antidepressants.
At our Portage practice, we offer TMS for patients whose depression has not responded well enough to standard treatment when it is clinically appropriate. TMS is not a medication, and it does not require surgery. It is also not appropriate for every patient, which is why evaluation is important before beginning treatment.
We discuss TMS in the context of the full treatment history, including diagnosis, prior medications, response to therapy, medical considerations, and safety factors.
Intranasal Ketamine and Treatment-Resistant Depression
We offer intranasal ketamine for treatment-resistant depression. Ketamine is FDA-approved as an anesthetic, but ketamine itself is not FDA-approved as a treatment for depression or other psychiatric disorders.
This means ketamine treatment for depression is considered off-label unless an FDA-approved esketamine product is being discussed separately. Ketamine and esketamine are different treatments and should not be used interchangeably. SPRAVATO® is an esketamine nasal spray with specific FDA-approved indications and REMS requirements, including administration under healthcare provider observation and post-treatment monitoring.
For patients considering ketamine treatment, we review diagnosis, treatment history, medical risks, potential side effects, monitoring, and whether the treatment is appropriate for that individual situation. Off-label use does not mean a treatment is automatically inappropriate, but it does mean the risks, limitations, and evidence should be discussed clearly.
Why Treatment-Resistant Depression Requires a Careful Approach
When depression has not responded to standard care, it can be tempting to search for the next treatment as quickly as possible. But more treatment is not always the same as better treatment. The next step should be based on a thoughtful review of what has already happened.
A careful approach matters because treatment-resistant depression may involve:
- Co-occurring psychiatric conditions
- Medication tolerability concerns
- Medical or sleep-related contributors
- Incomplete response rather than no response
- Diagnostic questions
- Safety concerns
- Multiple prior treatment attempts
- Different levels of support needed at different times
For some patients, the next step may be a medication change. For others, it may involve therapy coordination, TMS, off-label ketamine discussion, or another treatment strategy. The right path depends on the person.
Treatment-Resistant Depression Care in Portage and Kalamazoo
For patients in Portage, Kalamazoo, and surrounding communities, treatment-resistant depression can feel isolating. Many people have already tried to get better. They may have taken medication, gone to therapy, changed routines, or worked hard to keep functioning while still feeling depressed.
At Synergy NeuroPsychiatry, our approach is physician-led and focused on the whole patient. Mauli Verma, MD, is a board-certified psychiatrist with experience treating patients across inpatient and outpatient settings. When needed, our care may include coordination with a patient’s primary care physician, neurologist, nutritionist, psychologist, or other clinicians involved in treatment.
For patients whose depression has not responded as expected, we can help clarify diagnosis, review prior treatment response, and discuss what options may be appropriate. Patients can also review the mental health conditions we treat, contact our office with insurance and billing questions, or use the patient portal if they are already connected with our practice.
Conclusion
Treatment-resistant depression is not a personal failure. It is a clinical challenge that deserves careful reassessment, not blame. When standard treatments have not provided enough relief, a psychiatrist can help review the diagnosis, treatment history, co-occurring symptoms, and next options.
For some patients, that may include medication changes, therapy coordination, FDA-cleared TMS, off-label ketamine discussion, or other individualized treatment planning. The most important step is understanding the full clinical picture before deciding what comes next.
If depression symptoms remain persistent, complex, or difficult to manage, our practice in Portage, MI can help patients in the Kalamazoo-area community explore psychiatric care grounded in careful evaluation.
Frequently Asked Questions About Treatment-Resistant Depression
How do I know if my depression is treatment-resistant?
Treatment-resistant depression is often considered when depression symptoms do not improve enough after adequate treatment attempts. Many clinical discussions use the term after two or more antidepressant treatments have not provided sufficient relief, but definitions vary. A qualified clinician can help determine whether this term fits your situation.
Does treatment-resistant depression mean nothing will work?
No. Treatment-resistant depression means prior treatments have not worked well enough. It does not mean no options remain. It may mean the diagnosis, treatment history, co-occurring symptoms, and next treatment options need to be reassessed.
Can TMS help with treatment-resistant depression?
FDA-cleared TMS may be an option for some patients with treatment-resistant depression. It is not appropriate for everyone, and candidacy depends on diagnosis, treatment history, medical factors, and clinical evaluation.
Is ketamine FDA-approved for depression?
Ketamine is FDA-approved as an anesthetic, not as a treatment for depression or other psychiatric disorders. Ketamine treatment for depression is considered off-label unless a specific FDA-approved esketamine product is being discussed separately. Ketamine and SPRAVATO® should not be used interchangeably.
Should I stop my current depression treatment if it is not working?
No one should stop or change depression medication without guidance from a qualified healthcare professional. If treatment is not working or side effects are difficult to tolerate, speak with the prescribing clinician about what changes may be appropriate.
