What is TMS?
TMS therapy is based on the principle of electromagnetic induction discovered by
Michael Faraday in 1831. According to this principle a magnetic field can be induced
when passing an electrical current through a coil of wire. During a TMS treatment
an insulated magnetic coil is placed over the scalp. An electrical current is discharged
into the coil which creates a powerful magnetic field. This magnetic field (and
not the current directly) passes through the skull and scalp inducing a flow of
current in the brain, causing brain cells to fire. TMS is applied focally to an
area in the brain thought to be altered in depression.12
During a TMS session:
The strength of the magnetic field is similar to the strength of the magnetic field
induced by an MRI machine (1.5-3 Tesla).
You will be awake, resting comfortably in a reclining chair while receiving treatments.
Each treatment lasts about 40 minutes.
You will be able to resume your daily activities such as working or driving immediately
following your treatment.
Treatments are not painful, but you may experience some discomfort on the scalp
during the treatment or mild post-treatment headache.
During the TMS course our psychiatrist will meet with you periodically to monitor
your response to treatment.
Your treatment will be administered by a certified health care staff member under
the supervision of a physician.
