Transcranial Magnetic Stimulation, also known as TMS, uses a hand-held magnet, similar to the magnet used for MRI scans, that allows us to briefly stimulate a specific area of the brain
The magnet is held over the scalp of the participant and a brief, small magnetic pulse is generated. The magnetic pulse causes the brain cells in that area to activate and send an electrical signal through the brain. This magnetic pulse mimics the electrical signal that brain cells create when a person decides to move part of their body.
We place the magnet over the area of the brain that controls hand movement. When we generate the magnetic pulse, it causes a twitch in the participant’s finger. By studying the way children’s brains respond to this magnetic pulse, we can learn about the neural mechanisms that control body movement and effect motor development. By using TMS, we can compare the development of these neural mechanisms and brain areas in children with and without ADHD.
Our Center has been using TMS as research tool since 2001 and, to date, we have enrolled more than 100 children into research studies that use TMS. TMS is a painless, non-invasive procedure. Prior to your child’s first TMS session, they will have an opportunity to see the machine, meet our technicians, and see the magnetic pulse applied to one of our staff. This approach helps to alleviate worries around the procedure and feel comfortable during the sessions.
TMS does not allow us to diagnose any specific brain diseases.
