Transcranial magnet stimulation (TMS), a form of brain stimulation therapy, is available. This noninvasive treatment uses electromagnetic pulses to stimulate the nerve cells. It may help with symptoms of mental or neurological disorders.
The main purpose of TMS therapy for depression. It has been successful in treating people who are not responding to antidepressant medications or psychotherapy. TMS was approved by the Food and Drug Administration (FDA), in 2008.
TMS has been shown to be effective in treating anxiety and Parkinson's diseases.
Because TMS uses repetitive electrical impulses it is sometimes called repetitive magnetic stimulation. These terms are frequently interchangeable.
TMS Therapy: How it works
TMS therapy for depression works well where TMS technicians or TMS physicians perform the therapy. The procedure is performed in an outpatient setting, and may also be done in a clinic. You won't be required to stay over if it's done in hospital.
You will need to take out any items that are sensitive or magnet-sensitive, such as jewelry, before the procedure.
Here are some things you can expect from TMS:
• To reduce the sound of magnetic impulses clicking, your technician will recommend that you use earplugs. You will be seated in a comfortable chair. General anesthesia is not required. You will remain awake during the entire treatment.
• Your technician will take measurements of your head if this is your first session. To personalize the TMS machine's settings, they will also take additional measurements.
• The coil will be placed above your brain's frontal area by the technician. The technician will then begin the treatment.
• As the magnetic impulses are released, you'll hear a clicking sound. A tapping or knocking sound will also be felt beneath the magnetic coil.
• The procedure can take between 30 and 60 minutes. After the procedure, you can drive yourself home and resume your normal activities.
The procedure will be repeated five days per week for approximately 4 to 6 weeks. Your response and your specific condition will determine the length of your treatment.
TMS Therapy Benefits
TMS treatment has many benefits. Although the procedure is still being studied by researchers, it could be beneficial for the following conditions:
TMS treatment for depression
TMS is used primarily to treat major depression. This is recommended for people who have not found relief through medication or psychotherapy. This is treatment-resistant depressive. These treatments don't work for approximately 30% of those with depression.
According to 2015 research Trusted source; depression can be linked to decreased activity in the prefrontal cortex. Depression symptoms include low energy and changes in appetite.
TMS can stimulate nerve cells and increase activity.
TMS treatment for anxiety
TMS can be used to treat OCD and depression, as well as anxiety. These conditions can often lead to anxiety symptoms. TMS may also be helpful for generalized anxious disorder (GAD). Anxiety is often accompanied by increased activity of nerve cells in the prefrontal cortex. According to a 2019 study, TMS could reduce activity in this area.
TMS for stroke rehabilitation
Some evidence suggests that TMS may be beneficial in stroke rehabilitation. A stroke is a blockage or reduction in blood flow to the brain that causes brain cells to stop functioning properly. This can cause muscle weakness and even death.
According to research TMS could help motor recovery after strokes. The theory is that magnetic impulses could alter activity in the motor cortex, which controls voluntary movement.
TMS for chronic pain
TMS treatment may be able to improve chronic pain conditions such as fibromyalgia. An 2017 analysis trusted source shares that TMS may stimulate the motor cortex and control neurotransmitters related to pain.
Noting that depression can often be accompanied by chronic pain is important. Chronic pain can be made worse by depression, so TMS might help to treat it.
TMS to treat nicotine addiction
Dopamine is released by nicotine, which can lead to nicotine cravings or addiction. A 2013 study trusted source suggests that TMS may be able to reduce nicotine cravings through targeting the prefrontal cortex.
Researchers believe that TMS promotes dopamine release, which in turn reduces the need to smoke.
Success rate in TMS therapy
TMS therapy has been mostly studied as a treatment of depression. The success rate for TMS is encouraging. The response rates for depression are between 30% and 64 percent. To understand the success rate of other medical conditions, more research is required.
