Who can benefit from
TMS Therapy?
- Have you tried more than one antidepressant medication?
- Have medications failed to provide sufficient relief from your depression?
- Do the side effects of medication outweigh their benefits?
- Has depression led to increased visits to your doctor for other health concerns?
- Is depression interfering with your ability to work or earn a living?
- Does depression still feel like it has too much control over your life?
Mild and transient side effects
TMS’s side effects, such as scalp discomfort or headache, are mild and temporary. Tingling sensations, muscle twitching, or lightheadedness may also occur. These side effects resolve quickly and do not require specific treatment.
No Systemic Side Effects
Unlike medications, TMS avoids common side effects such as:
- Weight gain
- Sexual dysfunction
- Fatigue
- Gastrointestinal issues
Some patients may experience mild, temporary discomfort at the treatment site or a slight headache during the first few sessions, which usually resolves within a week.
Wide Availability and Accessibility
TMS is broadly accessible, with few contraindications, including:
- History of seizures or recent brain injury
- Presence of metal/magnetic implants near the brain (excluding dental fillings)
- Active psychosis or suicidal behavior
- Substance abuse or withdrawal
- Pregnancy (currently under research for safety and efficacy)
TMS Advantage
1. High Success Rate
TMS therapy has shown consistently high success rates, particularly for Treatment-Resistant Depression (TRD). Research and real-world data indicate:
- Response Rate (significant symptom improvement): 60-70%
- Remission Rate (full symptom resolution): 40-50%
These outcomes are particularly impressive given that most TMS patients have failed at least two antidepressant trials. By comparison, the likelihood of success with a third medication is only 15-20%, dropping even further with additional trials.
2. Prolonged Response
TMS offers not only immediate benefits but also sustained improvements:
- Approximately two-thirds of patients maintain their response a year after treatment.
- For those who relapse, repeat TMS therapy is highly effective, with more than 75% achieving a positive response.
This contrasts sharply with antidepressant therapies, where only one-third of patients on a third medication remain depression-free after one year, and the likelihood of success drops to 10% or less upon medication reintroduction.
3. Non-Invasive and does not require anesthesia
TMS uses magnetic fields to stimulate brain activity without inducing seizures or requiring anesthesia, unlike Electroconvulsive Therapy (ECT). Key safety features include:
- Does not affect cognitive function.
- Targeted Stimulation: Focuses on specific brain circuits linked to depression and anxiety.
- Minimal Risk of Seizures: Less than 1 in 30,000 treatments.
- No Recovery Time: Patients remain awake, alert, and can resume daily activities immediately after treatment.
TMS Limitations
1. Time Commitment
A standard TMS course lasts approximately 6 weeks, with an additional 3-week taper. This requires daily sessions, five days a week. While this may seem demanding, many patients view it as a valuable investment in their mental health. Advances like iTBS (intermittent Theta Burst Stimulation) offer shorter, three-minute sessions, and Accelerated TMS condenses the entire treatment into 5-10 days, offering more flexible options.
2. Insurance Prior Authorization
Obtaining insurance approval for TMS can be a hurdle. Requirements vary, with some insurers demanding proof of failure with up to four medications and therapy before authorizing TMS. Fortunately, we have a dedicated team skilled in navigating these processes to ensure timely approval.
3. Low Seizure Risk
While TMS is generally safe, individuals with a history of seizures are not recommended for treatment. However, for patients without predisposing conditions, the seizure risk is minimal—about 1 in 30,000 treatments—comparable to or lower than the risk associated with many antidepressants.
