Transcranial Magnetic Stimulation

What is transcranial magnetic stimulation (TMS)?

Transcranial magnetic stimulation (TMS) is a treatment that sends quick magnetic pulses into an area of the brain. It's used to treat certain health conditions. These include depression, obsessive compulsive disorder (OCD), and anxiety disorders. Experts don't know exactly how TMS helps relieve symptoms. But it seems to work by changing brain activity.

Why is transcranial magnetic stimulation (TMS) done?

TMS is a treatment option if you don't get better with medicines. It also may be done if you get side effects from medicines. Or it can be used along with medicines and other treatments, like counseling.

How is transcranial magnetic stimulation (TMS) done?

You will be in a doctor's office or hospital for the treatment. You'll be awake and will sit in a chair. The TMS device makes loud clicking sounds, so you will get earplugs to protect your hearing.

Your doctor will place the device against your head. You will get a few test pulses, and your doctor will adjust the device until your thumb twitches. This is how your doctor finds the right level for you.

You may feel some discomfort or muscle twitching during the treatment. You may feel this less as you have more treatments. If it's too strong, your doctor can turn down the level.

You'll be closely watched for any problems during the treatment. It will last about half an hour.
