Before treatment begins, the psychiatrist who is prescribing your TMS will need to identify the correct placement of the magnets on your head and the prescribed dose of magnetic energy for you. Your first appointment typically lasts about 60 minutes. During this appointment:
You will be taken to a treatment room, asked to sit in a reclining chair and given earplugs to wear during the procedure.
An electromagnetic coil will be placed against your head and switched off and on repeatedly to produce stimulating pulses. This results in a tapping or clicking sound that usually lasts for a few seconds, followed by a pause. You will also feel a tapping sensation on your forehead. This part of the process is called mapping.
The psychiatrist who is prescribing your TMS will determine the amount of magnetic energy needed by increasing the magnetic dose until your fingers or hands twitch. Known as your motor threshold, this is used as a reference point in determining the right dose for you. During the course of treatment, the amount of stimulation can be changed, depending on your symptoms and side effects.
The TMS psychiatrist will then issue a prescription for future treatment sessions, which will be adhered to by the TMS treatment Credentialed Clinician.
During each subsequent treatment you are seated in a comfortable chair. You are fully conscious and responsive. There are no medications involved in the treatment. The TMS clinician positions the magnet over the appropriate area of the scalp as prescribed by the psychiatrist and activates the magnet.
You will need to remove any metal hair clips, earrings and studs, glasses and hearing aids during your treatment. For ease of treatment it is preferable that you do not have gel, mousse or other products in your hair.
At the end of the treatment you can return to your usual routine activities, including driving your car.
