Non-obscene complex socially inappropriate behavior in Tourette's syndrome.

The authors surveyed 87 adolescent or adult patients with Tourette's syndrome (TS) regarding the presence, characteristics, and functional impact of non-obscene socially inappropriate (SI) behavior. Reported behaviors included insulting others (22%), other SI comments (5%), and SI actions (14%). More often, subjects described having an urge to carry out these behaviors (30%, 26%, 22%, respectively), which they often attempted to suppress. Non-obscene SI behavior was usually directed at a family member or familiar person, at home or in a familiar setting. Social difficulties commonly resulted. Non-obscene SI behavior is a common and potentially disabling feature of TS. It is closely associated with conduct disorder and attention deficit disorder and may represent part of a more general dysfunction of impulse control in TS.
