TMS needs to be delivered with accuracy and reliability
To ensure that brain activity normalises, TMS needs to be given multiple times every day for several weeks. Standard treatments require between 20 and 40 TMS sessions in total. The aim of each treatment session is to train the brain regions to communicate normally. This requires accurate and reliable stimulation.1
‘Standard’ TMS has some limitations
‘Standard’ TMS refers to the traditional practice of delivering TMS to a brain region based on surface landmarks on the scalp. This is the most common practice of TMS.
Using surface landmarks on the scalp to localise the DLPFC may be inaccurate and unreliable
At best, this approach roughly estimates the location of the brain region to stimulate. Of course, everyone has a unique brain size and shape, and this one-size-fits-all approach may not be optimal for all people. The DLPFC is a large brain region, and targeting it using surface markers on the scalp may be inaccurate and unreliable.
For example, research shows that in ‘standard’ TMS, different sites within the DLPFC are stimulated across sessions, and at times the wrong brain region is stimulated. 2, 3
Personalised TMS at Queensland Neurostimulation Centre improves accuracy and reliability
Personalised TMS accounts for an individual’s brain variability through the use of an MRI brain scan.
This personalised approach is what sets Queensland Neurostimulation Centre apart nationally and internationally as TMS providers.
