Alien hand syndrome is a term used to describe a variety of rare conditions in which uncontrolled behavior or feelings of strangeness are felt in one extremity, most commonly the left hand. Etiology usually involves infarct of the right anterior or posterior cerebral arteries or cortical-basal degeneration. The medical and neuropsychological data of an elderly female who suffered a left middle cerebral artery stroke with resulting right-sided alien hand sign is presented. Neuropsychological assessment revealed declines in visual- and perceptual-based abilities and right-sided motor and sensory abilities consistent with the affected areas indicated on neuroimaging. This case demonstrates the utility of neuropsychological assessment in patients with unusual sensory/motor presentations.
异己手综合征是一个用于描述多种罕见病症的术语，在这些病症中，患者会在某个肢体，最常见的是左手，感受到不受控制的行为或异样感。病因通常涉及右侧大脑前动脉或后动脉梗死或皮质基底节变性。本文呈现了一位老年女性的医学和神经心理学数据，该女性患有左侧大脑中动脉中风，导致右侧出现异己手征。神经心理学评估显示，基于视觉和感知的能力以及右侧运动和感觉能力下降，这与神经影像学所示的受影响区域一致。该病例证明了神经心理学评估在具有异常感觉/运动表现的患者中的实用性。
