What is TMS?
Transcranial Magnetic Stimulation (TMS) is a form of neuromodulation, a non-invasive technique that does not rely on causing seizures (like ECT) which stimulates brain tissue.
The process involves placing an electromagnetic coil on the head to deliver a short powerful burst of magnetic energy (1.5, Tesla similar to the power of an MRI scanner) through the scalp to induce electric current in the brain. TMS is a relatively new treatment method for mental health conditions but as been well established in neuroscience research experiments and as a clinical application for neurological conditions. It has been used for over 15 years in other countries such as the USA, China and Japan but has only been introduced to the UK since 2015 for mental health conditions. TMS is not currently funded by the NHS unless by special financial arrangements.
