Abstract

BACKGROUND

Psychogenic movement disorders (PMDs) may be difficult to differentiate from organic abnormal movements.

METHODS

We aimed to characterise the prevalence and clinical features of PMDs resembling tics during the last 3.5 years in our centre.

RESULTS

We studied 9 patients (five females) with psychogenic tics representing 4.9% of all 184 patients first evaluated for a PMD during the study period. The mean age at onset was 34.1 years. Lack of premonitory sensations, absence childhood and family history of tics, inability to suppress the movements and coexistence with other PMDs and pseudoseizures were common in our patients. Compared with 273 patients with Tourette syndrome, those with PMDs resembling tics were older: 36.3 versus 18.7 years (p=0.014) at presentation and more frequently female (p=0.030).

CONCLUSIONS

Movements resembling tics are observed in a small proportion of patients with PMDs. Clinical features can help to differentiate them from organic tics.

摘要

背景

心因性运动障碍（PMD）可能难以与器质性异常运动区分。

方法

我们旨在描述过去 3.5 年在我们中心类似抽动的 PMD 的患病率和临床特征。

结果

我们研究了 9 名女性患者（共 184 名 PMD 患者），他们的精神性抽动占 4.9%。发病的平均年龄为 34.1 岁。我们的患者普遍存在无预感、无儿童期和家族抽动史、无法抑制运动、与其他 PMD 和假性发作共存等特征。与 273 名妥瑞氏综合征患者相比，PMD 患者表现出以下特征：发病时年龄更大（36.3 岁比 18.7 岁，p=0.014），且更常见于女性（p=0.030）。
