A quick search of ADHD in practice turns up no previous references to Tourette’s syndrome or tics, and yet, services for people with Tourette’s syndrome are very much concerned with attention deficit hyperactivity disorder (ADHD). Tourette’s syndrome is defined by a combination of chronic motor and vocal tics – that is, it is a movement disorder. The abnormal movements and vocalisations associated with the condition have a very wide range of severity. However, even mild cases are of importance, as Tourette’s syndrome is characterised by the presence of co-morbidities – the most common being obsessive–compulsive disorder (OCD) and ADHD.
