Premonitory Urge in Tourette Syndrome

The premonitory urge is the sensory phenomenon that precedes a tic — described by patients as a building tension, an itch, a pressure, or an electrical sensation that is only relieved by performing the tic. It is the most treatment-relevant feature of Tourette syndrome because it provides a window of opportunity for intervention.

InhibiTic is built on the premonitory urge. The device's EEG system monitors brain activity in real time, and a proprietary classifier detects the unique brainwave signature that appears before tic onset. By intervening at the moment of the urge, the device stops the tic before it starts — without affecting anything else.
