This editorial examines the rise of attention-deficit hyperactivity disorder (ADHD) in the digital age, suggesting that excessive digital media use may mimic or exacerbate ADHD symptoms.

In this issue, using data from a large, prospective, population-based cohort of children, Mathews et al examine associations of pre- and perinatal exposures with Tourette syndrome and other chronic tic disorders. Their work illustrates the importance of environmental factors in the aetiology of neuropsychiatric conditions and the value of replication in science.
