TL;DR: TMS (Transcranial Magnetic Stimulation) is non-invasive, durable, and well-tolerated, while ketamine offers rapid relief but may require ongoing infusions. Both are FDA-approved for treatment-resistant depression (TRD). The best choice depends on urgency, side-effect tolerance, medical history, and access to care with a trusted neurologist Jacksonville FL.
When standard antidepressants fail, patients often feel stuck without options. Fortunately, advanced therapies like TMS and ketamine have opened new doors for those living with treatment-resistant depression. Both are FDA-approved, but they differ in speed, side effects, and long-term results.
In this article, you will learn how TMS and ketamine work, their key differences, and how to decide which treatment may be the best fit for your needs.
Treatment-resistant depression (TRD) affects patients who do not respond to at least two standard antidepressants. About one-third of people with depression fall into this category. For these individuals, innovative treatments like TMS and ketamine may provide new hope.
Transcranial Magnetic Stimulation (TMS) uses electromagnetic pulses to stimulate brain regions linked to mood regulation, most often the dorsolateral prefrontal cortex (DLPFC).
Ketamine, originally an anesthetic, alters glutamate transmission in the brain, rapidly improving mood and depressive symptoms.
| Feature | TMS (Transcranial Magnetic Stimulation) | Ketamine |
|---|---|---|
| Mechanism | Magnetic pulses stimulate DLPFC | Alters glutamate transmission |
| Setting | Outpatient clinic, no hospitalization | Infusion or intranasal in clinic |
| Anesthesia | Not required | Not required |
| Response Speed | Gradual (weeks) | Rapid (hours) |
| Side Effects | Mild headache, scalp tingling | Dissociation, dizziness, potential dependence |
| Effectiveness | ~50% response, 30% remission | ~70% response, rapid symptom relief |
| Best For | Patients seeking non-invasive, durable results | Patients needing urgent relief or who haven’t responded to other therapies |

Recent studies suggest that combining TMS with ketamine may offer enhanced results for TRD. TMS promotes neuroplasticity, while ketamine provides rapid symptom relief. Together, they may deliver both immediate and lasting benefits, especially for patients who have not responded to other approaches.

What is treatment-resistant depression (TRD)?
TRD refers to depression that does not respond to at least two conventional antidepressants. Around one-third of depression patients face this challenge.
How does TMS work?
TMS uses electromagnetic pulses to stimulate the DLPFC, enhancing neural activity linked to mood regulation.
How does ketamine work?
Ketamine alters glutamate transmission, leading to rapid improvements in mood, often within hours of treatment.
What are the side effects of TMS and ketamine?
TMS: mild headache, scalp tingling, fatigue.
Ketamine: dissociation, dizziness, nausea, possible dependence.
Can TMS and ketamine be used together?
Yes. Some clinics explore combined protocols to maximize both rapid relief (from ketamine) and long-term improvements (from TMS).
Which is better for me: TMS or ketamine?
The right choice depends on urgency, side effect tolerance, medical history, and lifestyle. A consultation with a specialist can help guide the decision.
