Depression is more than a low mood or one hard week. It is a medical condition that can change how you think, feel, sleep, and move through an ordinary day. If therapy and medication have not brought the relief you hoped for, it does not mean you are out of options. It may mean it is time to consider a different kind of treatment.
Understanding Major Depressive Disorder
Major depressive disorder (MDD), often called clinical depression, is one of the most common mental health conditions in the United States. According to the National Institute of Mental Health, it can cause symptoms severe enough to affect how you feel, think, and handle daily activities such as sleeping, eating, and working. It is not a sign of weakness or something you can simply will away, and research points to a mix of genetic, biological, environmental, and psychological factors behind it.
What separates clinical depression from an ordinary rough patch is how long it lasts and how much it interferes with your life. MedlinePlus describes major depression as a depressed mood or loss of interest that lasts at least two weeks, present most of the day, nearly every day. Common signs include persistent sadness or emptiness, losing interest in things you used to enjoy, changes in sleep or appetite, low energy, trouble concentrating, feelings of worthlessness or guilt, and thoughts of death or self-harm.
There is no single blood test for depression. A diagnosis comes from a clinical evaluation, where a provider reviews your symptoms, your history, and how long things have been going on. Many clinicians also use a brief standardized questionnaire such as the PHQ-9 to measure symptom severity and track it over time. The goal is to understand your full picture and rule out other causes before recommending any treatment. Depression is common, it is treatable, and a real evaluation is the first step toward a plan that fits you.
When Therapy and Medication Aren't Enough
For many people, talk therapy, antidepressant medication, or a combination of the two brings meaningful relief. These are evidence-based, first-line treatments, and they work well for a large share of people living with depression. But they do not work for everyone, and that can be discouraging when you have done everything that was asked of you and still feel stuck.
If you have given medication and therapy a fair try without enough improvement, there is a name for that experience. When depression has not responded adequately to two or more antidepressant trials taken at an appropriate dose and for an appropriate length of time, clinicians often describe it as treatment-resistant depression. It is more common than most people realize, and it is not a personal failure. Depression is complex, and not everyone's brain responds to the same medication the same way.
This is also where measurement matters. Tracking your symptoms over time with a tool like the PHQ-9 helps you and your provider see whether a treatment is actually moving the needle, rather than relying on memory alone. If the numbers are not improving after a reasonable trial, that is useful information, not a dead end. It can be the signal to look at approaches that work through a different mechanism than the medications you have already tried.
Wondering if TMS could be right for you?
Your provider and TMS team determine eligibility. Individual responses vary.
How TMS Fits Into Depression Care
Transcranial magnetic stimulation (TMS) is a non-invasive, medication-free treatment that is FDA-cleared for major depressive disorder. It is typically considered when antidepressants and therapy have not provided enough relief. Rather than acting on your whole body the way an oral medication does, TMS targets specific areas of the brain involved in mood regulation.
During a session, a coil placed against your scalp delivers brief magnetic pulses, similar in strength to an MRI, to mood-regulating regions of the brain. MedlinePlus notes that repetitive transcranial magnetic stimulation (rTMS) uses magnetic waves to relieve depression, does not require anesthesia, and carries a low risk of negative effects on memory and thinking. The National Institute of Mental Health notes that the first rTMS device was FDA-cleared back in 2008 for depression in people who had not responded to at least one antidepressant in their current episode.
Treatment is delivered as a series of short outpatient sessions over several weeks. You stay awake and alert, and most people return to their normal activities right after each visit. It is important to be honest about expectations: TMS is not a guarantee, and individual responses vary. For appropriate candidates, though, it can support improvement in mood, motivation, energy, sleep, and focus, and for many people it becomes a meaningful next step. Whether TMS is right for you is a decision made with a qualified provider after an evaluation.

Key Terms
Major Depressive Disorder (MDD)
A medical condition involving persistent low mood or loss of interest that lasts at least two weeks and interferes with daily life. Also called clinical depression.
PHQ-9
A nine-question screening tool clinicians use to measure the severity of depression symptoms and track how they change over the course of treatment.
Anhedonia
The loss of interest or pleasure in activities you once enjoyed. It is one of the core symptoms used to diagnose major depressive disorder.
Treatment-Resistant Depression
Depression that has not responded adequately to two or more antidepressant medications tried at an appropriate dose and duration. It signals a need to consider options beyond standard medication.
Neuromodulation
Treatments that work by directly influencing activity in specific brain circuits. TMS is a non-invasive form of neuromodulation used for depression.
Remission

Frequently Asked Questions About Depression
What is major depressive disorder?
Major depressive disorder (MDD), often just called clinical depression, is a medical condition that affects how you feel, think, and handle daily activities. It is more than a low mood or a rough stretch. MDD involves persistent sadness or loss of interest that lasts at least two weeks and interferes with work, relationships, sleep, and energy. It is common and treatable, and a clinical evaluation is the first step toward a plan that fits you.
What are the symptoms of major depressive disorder?
Symptoms vary from person to person, but commonly include a persistent low or empty mood, loss of interest in things you used to enjoy, changes in sleep or appetite, fatigue, trouble concentrating, feelings of worthlessness or guilt, and thoughts of death or self-harm. A diagnosis is based on a clinician's evaluation, not a checklist alone. If you are experiencing several of these most of the day, nearly every day, it is worth talking with a provider.
How is major depressive disorder diagnosed?
There is no single lab test for depression. A diagnosis comes from a clinical evaluation where a provider reviews your symptoms, history, and how long things have been going on, often alongside a standardized measure like the PHQ-9 to track symptom severity over time. The goal is to understand your full picture and rule out other causes before recommending a treatment approach.
What are the treatment options for major depressive disorder?
Depression is typically treated with psychotherapy, medication, or a combination of both. For people who have not found relief from medication, additional options exist, including TMS (transcranial magnetic stimulation), an FDA-cleared, non-invasive treatment for major depressive disorder. The right approach depends on your history, your symptoms, and a conversation with your provider. Individual responses to any treatment vary.
What is treatment-resistant depression?
Treatment-resistant depression generally refers to major depressive disorder that has not responded adequately to two or more antidepressant medications tried at an appropriate dose and duration. It does not mean nothing will help. It means it may be time to look at approaches beyond standard medication. TMS is one FDA-cleared option clinicians consider for treatment-resistant depression.
Can TMS help with major depressive disorder?
TMS is an FDA-cleared treatment for major depressive disorder and is often considered when medication has not provided enough relief. It uses targeted magnetic pulses to stimulate areas of the brain involved in mood regulation. It is non-invasive, medication-free, and typically done in a series of outpatient sessions. Individual responses vary, and results are not guaranteed. A consultation is the best way to find out whether TMS is appropriate for your situation.
Is treatment for depression covered by insurance?
Many insurance plans cover depression treatment, and coverage for TMS has expanded as it has become an established option for major depressive disorder. Coverage depends on your specific plan and clinical criteria. Our team can help verify your benefits and walk you through what to expect before you commit to anything.
