Restless arms syndrome (RAS) is characterized by uncomfortable aching or burning sensations in the arms. RAS is regarded as an upper limb variant of restless legs syndrome (RLS). The lack of specific diagnostic criteria makes it difficult to recognize the RAS. Therefore, RAS is usually neglected in clinical practice. Moreover, when a patient was diagnosed with RAS, the adjustment of medications was the first choice for doctors, which may make the patient’s condition unstable. A 33-year-old woman was diagnosed with schizophrenia and major depressive disorder. Starting with 0.6 g/d amisulpride, 0.1 g/d quetiapine, 75 mg/d venlafaxine sustained-release tablets, the patient reported symptoms of RAS (itching arms) on the fourth day since the latest hospitalization. After ruling out other factors, her RAS was suspected to be induced by antidepressants or antipsychotics. Without medication adjustment, RAS spontaneously remitted. This case suggests that psychiatrists should pay attention to RAS when using antipsychotics and/or antidepressants. Moreover, RAS may be transitory. When a patient manifests RAS, observation may be one choice instead of an immediate medication adjustment.

服用抗精神病药和抗抑郁药患者的短暂性不安臂综合征：病例报告

不安臂综合征 (RAS) 的特征是手臂不舒服的疼痛或灼热感。RAS 被认为是不宁腿综合征 (RLS) 的一种上肢变异。由于缺乏具体的诊断标准，很难识别 RAS。因此，RAS在临床实践中通常被忽视。而且，当患者被诊断出患有RAS时，调整药物是医生的首选，这可能会使患者的病情不稳定。一名 33 岁的女性被诊断出患有精神分裂症和重度抑郁症。从 0.6 g/d 氨磺必利、0.1 g/d 喹硫平、75 mg/d 文拉法辛缓释片开始，患者在最近一次住院后的第四天报告了 RAS（手臂瘙痒）症状。排除其他因素后，她的 RAS 被怀疑是由抗抑郁药或抗精神病药引起的。无需药物调整，RAS自发缓解。本病例提示精神科医生在使用抗精神病药和/或抗抑郁药时应注意RAS。此外，RAS 可能是暂时的。当患者出现 RAS 时，观察可能是一种选择，而不是立即调整药物。
