Transcranial Magnetic Stimulation (TMS)
Transcranial Magnetic Stimulation (TMS) is a treatment for depression that uses an electromagnet. We place the magnet next to your head to generate controlled electric currents within the brain.
- Is a FDA-cleared for treatment of Major Depressive Disorder (MDD)
- Is gentle with less side effects compared to most medications
- Causes activation of brain cells, and of pathways in the brain, that play a role in depression
- Is non-invasive, so there is no need for anesthesia and you can drive yourself to and from treatments
TMS treatment schedule
We schedule TMS treatments daily, five days per week, for six weeks. We then follow with a "taper" period, consisting of:
- Three treatments in week seven
- Two in week eight
- Final treatment in week nine
There are 36 treatments in total.
We schedule the first treatment session for 45 minutes to tailor the treatment for you. All following treatments are typically less than 5 minutes in duration.
You can drive yourself to and from TMS appointments. You can also engage in all normal activities on days when you have TMS.
Risks and side-effects of TMS
Common side effects include:
- Mild to moderate pain at the stimulation site
- Twitching of facial muscles
- In rare cases, TMS can cause an unintentional seizure < 0.1%
Medical conditions that are not safe with TMS
In general, TMS is not safe for patients who have magnetically-sensitive implants in their head. TMS also isn't safe for patients who have implants within 12 inches (30 cm) of the treatment coil, such as:
- Aneurism clips or coils
- Bullet fragments
- Cardiac pacemakers or defibrillators
- Cerebral shunts
- Cochlear implants
- Stents in the brain
TMS may also not be safe if you have a history of seizures, or other medical conditions. Before starting TMS, we will review your medical history with you.
TMS medical insurance coverage
For appropriately-qualified patients, TMS is usually covered by insurance.
TMS insurance coverage guidelines
TMS is necessary for adults who have a confirmed diagnosis of MDD or have a single or recurrent episode.
You must submit medical records to your insurance that shows that TMS is necessary.
Insurance coverage criteria
