Functional (psychogenic) movement disorders (FMDs) are conditions in which affected patients develop abnormal movements that are incongruous with known, organic, movement disorders, often associated with psychological stressors.
In this case series, electronic medical records of all patients who presented to our adult and pediatric tertiary care movement disorders clinics between March 1 and October 30, 2020, and during the same period in 2019 were reviewed. All patients diagnosed with functional (psychogenic) movement disorder were included if they satisfied diagnostic criteria.
Among 550 new patients referred for evaluation at our tertiary care movement disorders centers, 45 (8.2%) received a diagnosis of FMD; 75.6% were female, in comparison to the prior year during which time 665 new patients were evaluated and 5.1% were diagnosed with FMD. This represents a 60.1% increase (90.1% in pediatric cohort, 50.9% in adult cohort) in new patients diagnosed with FMD during the COVID-19 pandemic.
Within our patient population, there has been increased incidence of FMDs in the setting of the COVID-19 pandemic, possibly reflecting increased psychological and other stressors during this period.
功能性（心因性）运动障碍（FMDs）是指受影响的患者出现与已知的器质性运动障碍不一致的异常运动，常与心理应激源相关。
在本病例系列中，回顾了2020年3月1日至10月30日以及2019年同期到我们成人及儿科三级医疗运动障碍诊所就诊的所有患者的电子病历。所有符合诊断标准且被诊断为功能性（心因性）运动障碍的患者均被纳入。
在我们三级医疗运动障碍中心转诊来接受评估的550名新患者中，45名（8.2%）被诊断为FMD；75.6%为女性，而前一年有665名新患者接受评估，5.1%被诊断为FMD。这表明在新冠疫情期间，被诊断为FMD的新患者增加了60.1%（儿科队列增加90.1%，成人队列增加50.9%）。
在我们的患者群体中，新冠疫情期间FMD的发病率有所上升，这可能反映了在此期间心理及其他应激源的增加。
