Scottish campaigner John Davidson MBE was first diagnosed with Tourette’s Syndrome at the age of 15 in the late 1980s, a time when little was known about the condition.

In 1989, he became the subject of the BBC documentary John’s Not Mad, which explores the manifestations of Tourette’s syndrome that he lived with, followed by several BBC follow-up films throughout his life.
