Functional movement disorder is a subtype of functional neurologic symptom disorder a syndrome of involuntary physical, neurologic-type symptoms that are incongruous with "organic" disease. 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.
We describe six teenage girls, each with the explosive onset of tic-like movements. Mean age of onset was 14.2 years. 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.
Our series suggests that social media may contribute to the spread of functional neurologic symptom disorder, in a way previously requiring physical proximity.
功能性运动障碍是功能性神经症状障碍的一种亚型，是一种非自愿的身体、神经类型症状的综合征，与“器质性”疾病不一致。纵观历史，社区中曾爆发过功能性症状；直到最近，传播范围还局限于身处同一地点的人群。然而，在社交媒体时代，可能出现了一种新的传播方式。
我们描述了六名十几岁的女孩，她们都突然出现类似抽搐的动作。平均发病年龄为14.2岁。病史和检查中存在与抽动秽语综合征不符的特征，促使诊断为功能性抽搐。所有患者均报告在症状出现前接触过一位特定的社交媒体名人。
我们的系列病例表明，社交媒体可能以一种以前需要身体接近才能传播的方式，促成功能性神经症状障碍的传播。
