MEETING ABSTRACT Open Access Tourette syndrome: current data, comorbidities,

Tourette syndrome (TS) is the primary tic disorder with an estimated prevalence close to 1 % between 5 and 18 years of age [1]. Motor and phonic tics are the core fea-tures of TS [2]. In addition to their well-characterized phe-nomenology, tics display a peculiar variability over time, which is strongly influenced by a variety of contextual fac-tors. A relevant proportion of patients with TS display complex, tic-like, repetitive behaviors that include echo-phenomena, coprophenomena, and nonobscene socially inappropriate behaviors (NOSIBs). Co-morbid conditions are attention deficit hyperactivity disorder (ADHD), obses-sive compulsive behaviours/disorder (OCB/D) and autistic spectrum disorder (ASD); co-existent psychopathologies include depression, anxiety, oppositional defiant disorder (ODD), conduct disorder (CD) and personality disorder
