Watch: 'Life-changing moment' boy turns on Tourette syndrome device to help stop tics

A wrist device developed by researchers in the University of Nottingham is changing the lives of people with Tourette sydrome in an "instant". The small device works by delivering electrical pulses to the median nerve at the wrist, which trials have shown can change the activity in the parts of the brain involved in movement control. Among the users of this new device is 15-year-old Ollie, from Cheshire, who started making involuntary neck movements nearly two years ago.
