Core tip: Attention deficit hyperactivity disorder (ADHD) and Tic disorders (TD) are common co-morbidities in children and adolescents, with 60% of children with Tourette’s syndrome having ADHD. This review covers the classification, prevalence, aetiology, diagnosis and treatment of childhood TD and co-morbid ADHD. Most tics are mild or moderate, responding to psychoeducation and behavioural management. Level A evidence supports the use of alpha adrenergic agonists, Atomoxetine and stimulants for the treatment of Tics and co-morbid ADHD. Severe TDs may require antipsychotic treatment. Short clinical vignettes are presented to help guide the selection of the most appropriate treatment in each patient presenting with ADHD and co-morbid TDs.
