Horizon: Mad but Glad

Is there really such a thing as the mad genius? Can an illness be a blessing and a curse? By the age of 20, Nick Van Boss was award-winning international pianist. He felt sure that his illness had made him the success he was. But had it? The programme follows Nick's personal journey of discovery to see whether Tourettes made him the man that he is. It is a path that takes him to a manic writer, a schizophrenic painter, a composer with Parkinsons disease, and a fellow Tourettes musician.
