Interpersonal reactivity differences in Tourette syndrome.

Tourette syndrome (TS) frequently involves complex tics with social significance, including imitation or socially inappropriate behaviour. This study explored every-day perspective taking and empathic tendencies in 95 patients with TS and 60 healthy controls. Analyses indicated that both males and females with TS exhibited a different interpersonal reactivity profile to controls, characterised by a reduced tendency to take other people's perspectives, and elevated personal distress in response to intense emotional situations (e.g. people experiencing crises).
