In contrast to well-documented deficits in the core social cognitive domains of social perception and theory of mind (ToM), how Parkinson's disease (PD) affects one's empathic capacity remains poorly understood. The current study provides the first meta-analytic review of both ToM and empathy as broad constructs, and also breaks these constructs down to clearly differentiate their overlapping (affective ToM and cognitive empathy) and distinct (affective empathy and cognitive ToM) components. A total of 38 studies contributed to these analyses, with results revealing that, relative to controls, PD is associated with significant and substantial deficits in the domain of cognitive ToM (g = -0.78), as well as the overlapping domains of affective ToM/cognitive empathy (g = -0.69). However, no group differences were identified for affective empathy (g = -0.08). These data speak to there being a potential preservation of affective empathic processing in PD, but because of the relatively limited research base on this topic, recommendations for future research are highlighted.

帕金森氏病的移情和心智理论：一项荟萃分析。

与社会知觉和心理理论（ToM）的核心社会认知领域中有据可查的缺陷相反，帕金森病（PD）如何影响人的移情能力仍然知之甚少。当前的研究首次对ToM和共情作为广义结构进行了荟萃分析，并细分了这些结构以清楚地区分它们的重叠部分（情感性ToM和认知同情）和不同的要素（情感性共情和认知ToM）。总共38项研究为这些分析做出了贡献，结果表明，相对于对照，PD与认知ToM领域（g = -0.78）以及情感ToM /认知移情（g = -0.69）。然而，没有发现情感移情的群体差异（g = -0.08）。这些数据表明，PD中情感移情处理可能得到保留，但是由于基于该主题的研究相对有限，因此着重提出了对未来研究的建议。
