What is TMS?
Transcranial Magnetic Stimulation (TMS), also called repetitive Transcranial Magnetic Stimulation (rTMS) is a non-invasive procedure used for the treatment of depression and other mental health conditions. It involves the use of magnetic fields to stimulate specific areas of the brain associated with depression symptoms.
Frequently Asked Questions
Commonly Reported Side-effects
1Discomfort or pain at the treatment site
During the procedure, some individuals may experience mild discomfort or pain at the area where the magnetic coil is placed on the scalp. This discomfort is usually temporary and typically resolves after the session. The intensity of the sensation can vary from person to person.
2Scalp discomfort or headaches
Some individuals may experience scalp discomfort or mild headaches following the treatment session. These side effects are usually mild and transient, but in rare cases, they can be more persistent. Adjustments to the stimulation parameters can sometimes help alleviate these symptoms.
3Lightheadedness or dizziness
It is not uncommon for individuals to feel lightheaded or slightly dizzy during or immediately after the TMS session. These sensations typically subside quickly, but it is important to inform the healthcare provider if they are persistent or severe.
4Muscle twitching
The magnetic pulses used in TMS may cause muscle twitches in the scalp or face during the treatment. These twitches are usually harmless and subside after the session. In rare cases, they can be uncomfortable or bothersome.
5Hearing-related effects
The magnetic pulses can produce clicking or tapping sounds as the coil is activated. While earplugs or headphones are typically provided to minimize the noise, some individuals may still experience mild discomfort or hearing changes during the treatment. These effects are temporary and should not cause any long-term issues.
6Seizures
Although rare, the risk of seizures is a potential side effect of TMS. The incidence of seizures associated with rTMS is low, estimated to be less than 0.1%. However, individuals with a higher risk of seizures, such as those with a history of epilepsy or certain brain abnormalities, should be evaluated carefully before undergoing TMS treatment.
Key Findings About TMS
1Clinical remission rates
Many studies have reported remission rates ranging from 30% to 60% among patients who received rTMS treatment for depression. Remission refers to a substantial reduction in depressive symptoms to the point where an individual no longer meets the criteria for a depressive disorder.
2Response rates
Response rates measure the proportion of individuals who experience a significant reduction in depressive symptoms, even if they don’t reach full remission. Response rates for TMS treatment have been reported to range from 30% to 80%.
3Treatment-resistant depression
TMS has been particularly effective in treating individuals with treatment-resistant depression (TRD) or difficult-to-treat depression, which refers to depression that has not adequately responded to multiple antidepressant treatments. Studies have consistently shown that TMS can lead to significant symptom improvement and remission rates in individuals with TRD.
4Long-term effects
TMS has not shown any significant long-term side effects. Studies have consistently shown that TMS can lead to significant symptom improvement and remission rates in individuals with TRD and, for some, last over a year without changes in medications.
5Multiple medical conditions
TMS is a highly effective treatment option, particularly for individuals who encounter medical challenges that may hinder their ability to make adjustments to their medications. This innovative therapy provides a promising avenue for those who face complexities in managing their medication regimens due to underlying medical conditions.
*It’s important to remember that side effects can vary from person to person, and not everyone will experience them. Most side effects associated with rTMS are mild and transient, resolving on their own without any long-term consequences. Our trained healthcare team always administers the treatment under the supervision of a physician who can monitor the session and address any concerns or side effects that may arise.
