揭秘“奇爱博士”的手——异己手综合征的现象学精神病理学解读

Unveiling Dr.Strangelove's Hand: Interpretation of the Enigma of Alien Hand Syndrome from Phenomenological Psychopathology

异己手综合征是神经精神病学领域内最引人注目的病理现象之一。按照临床神经病学的界定,患者的某只手似乎按照本身的意志呈现目的性的协调动作或姿势,而另一只手则试图干扰和对抗这种正在进行的活动。这使得患者对自己的躯体感到陌生和疏远。结合脑与认知神经科学的最新证据,以及现象学方法论,现象学精神病理学试图从拥有感与自主感这一对概念入手,尝试解读异己手综合征的主观体验,并给出一种融合第一人称与第三人称视角的干预措施。

The alien hand syndrome （AHS） represents a remarkable neuropsychiatric disorder. According to pbenomenological psychopathology, one of the patient＇s hands displays purposeful, coordinated behavior or posture as if it has ＂a will of its own＂ with contrasting behavior against such motor activities in the other hand. The patient therefore experiences ＂estranged body＂ feelings. Ac- cording phenomenological psychopathology, it is pragmatic to consider the neural mechanisms underpinning and the symptoms of AHS, and give phenomenological descriptions for first personal experience of AHS simultaneously. The AHS patient loses the sense of agency, however, in this case the hand that cannot be controlled is still mostly recognized as being part of the subject~ own body and subject to their ＂ ownership＂. We finally propose that future studies should design if rehabilitation training and physical therapy for AHS based on reciprocal constraints of the first person and third person methods.
