IntroductionThe delusion of being a living animate non-animal object has not heretofore been reported.MethodsA 21-year-old right-handed cisgender female, two months prior to presentation, noted stiffness and difficulty with ambulation. One-month prior to admission, she experienced recurrent depression with myriad vegetative and nonvegetative symptoms of depression. On admission her chief complaint was I am a tree, standing motionless and minimally responding to query. After treatment with quetiapine, mirtazapine and hydroxyzine for a one-week period, her perception of being a tree fully resolved.ResultsAbnormalities in Mental Status Examination: Anxious mood repeatedly stating, I am a tree. Standing still for long periods of time, refusing blood pressure to be obtained and expressing fear of constricting flow. Neuropsychiatric Testing: Beck Depression Inventory Type II: 33 (severe depression)DiscussionThe rapid response to risperidone is consistent with Cotard’s syndrome, which has been noted to respond rapidly to neuroleptics (Sharma, 2014). However, in Cotard’s syndrome, replacement by a living non-animal object has not hitherto been reported. Body infestation with animate objects, as in Ekbom syndrome, only includes animals not botanicals (Chaudhary, 2019). This could be viewed as Reverse Inanimate Capgras Syndrome: instead of an imposter replacing a close friend, who then is inserted into the sufferer; a tree has replaced the sufferer. Peradventure, this may fit into the construct of Intermetamorphosis, a misidentification syndrome associated with the belief that individuals have transformed into other persons (Jariwala, 2017). Botanical Intermetamorphosis, the belief by the sufferer that the other individual is transformed from a person into a plant has not been described. Reverse Intermetamorphosis is the projection of an external individual into the person suffering or a syndrome of altered physical and psychological identities of the self (Silva, 1990). However, in this situation, the objects are all human or animate animals not botanicals. In Fregoli syndrome, there is an altered physical identity of others. In Reverse Fregoli syndrome, the sufferer assumes the physical but not the psychological identity of the stranger (Silva, 1990). But in this instance, the stranger is human as opposed to a plant life form. In the current case there is only altered physical identity (into a tree) not psychological identity. The current case may also be interpreted as a Botanical Variant of Interparietal Syndrome. In this condition, parts of the body are perceived to be lifeless, due to lesions of the inferior parietal lobe including supramarginalis gyrus, angular gyrus and the basalis parietalis area (Angyal, 1935). Investigation for those whom have Intermetamorphosis, Fregoli syndrome, Capgras syndrome, Interparietal syndrome, and Cotard’s syndrome for the presence of delusions involving plant life is warranted.

反向弗雷戈里综合征的木学变异，是一棵树的错觉

介绍迄今为止尚未报道过作为有生命的非动物物体的错觉。方法一名 21 岁的右利手顺性别女性，在就诊前两个月，注意到僵硬和行走困难。入院前 1 个月，她经历了反复发作的抑郁症，伴有多种植物性和非植物性抑郁症状。入院时，她的主要抱怨是我是一棵树，一动不动地站着，对询问的反应很少。服用喹硫平、米氮平、羟嗪一周后，完全消除了她是一棵树的感觉。结果精神状态检查异常：焦虑情绪反复说，我是一棵树。长时间静止不动，拒绝测量血压，害怕血流受限。神经精神测试：Beck 抑郁量表 II 型：33（重度抑郁）讨论对利培酮的快速反应与 Cotard 综合征一致，该综合征已被注意到对精神抑制药反应迅速（Sharma，2014）。然而，在科塔尔综合征中，迄今尚未报道用活的非动物物体替代。与 Ekbom 综合征一样，有生命物体的身体感染仅包括动物而非植物（Chaudhary，2019 年）。这可以被视为反向无生命 Capgras 综合症：而不是冒名顶替者代替密友，然后将其插入患者体内；一棵树取代了受难者。Peradventure，这可能符合 Intermetamorphosis 的构造，这是一种与个人已经转变为其他人的信念相关的误认综合症（Jariwala，2017 年）。植物间变态，受害者相信另一个人从人变成植物的信念尚未被描述。反向互变是外部个体投射到遭受痛苦的人或自我的身体和心理身份改变的综合征（Silva，1990）。然而，在这种情况下，对象都是人类或有生命的动物，而不是植物。在弗雷戈里综合征中，其他人的身体身份发生了改变。在 Reverse Fregoli 综合征中，患者承担了陌生人的身体而非心理身份（Silva，1990）。但在这种情况下，陌生人是人类而不是植物生命形式。在当前情况下，只有改变的身体身份（变成一棵树）而不是心理身份。目前的病例也可能被解释为顶叶综合征的植物变异。在这种情况下，由于包括边缘上回、角回和基底层顶叶区域在内的顶下叶的病变，身体的某些部分被认为是没有生命的（Angyal，1935）。有必要对患有 Intermetamorphosis、Fregoli 综合征、Capgras 综合征、顶叶综合征和 Cotard 综合征的人进行有关植物生命错觉的调查。
