Tourette's rewired.

This documentary looks at how 'deep brain stimulation' surgery can help people suffering with severe Tourette Syndrome. We meet Sean Hume for whom the surgery was life-changing, and Keith whose Tourette's tics are so bad they are frequently life-threatening and who is desperate to try out the surgical option. Hardly any neurosurgeons will attempt this operation, but 75-year-old neurosurgeon Donald Richardson is one who will. We follow Keith through his surgery and recovery time afterwards. We also hear about 13-year-old Brett who had the surgery but became very ill with meningitis afterwards.
