Throughout history, there have been outbreaks of functional symptoms in communities; until recently, spread had been confined to groups of people who shared a physical location. However, in the era of social media, a new mode of dissemination may have arisen.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Cases<\/jats:title>\n                    <jats:p>We describe six teenage girls, each with the explosive onset of tic\u2010like movements. Mean age of onset was 14.2\u2009years. The presence of features incongruous with Tourette syndrome on history and examination prompted the diagnosis of functional tics. All patients reported exposure to a specific social media personality before symptom onset.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
