Although shadowing behavior- when one individual closely follows another- is routinely documented among patients with dementia, its mechanisms have yet to be elucidated. In particular, there have been no detailed descriptions of patients with shadowing behavior. To propose its potential backgrounds, we describe a patient with posterior cortical atrophy who exhibited prominent shadowing behavior. He also experienced severe difficulties recognizing external stimuli, including visuospatial dysfunction, several types of agnosia, difficulties in verbal comprehension, disorientation, and its associated depression. This shadowing behavior may be adaptive relative to his extreme difficulty with recognizing the world around him.
虽然在痴呆症患者中，当一个人紧跟另一个人时会出现尾随行为，但这种行为的机制尚未阐明。特别是，还没有对有尾随行为的患者进行详细描述。为了提出其潜在的背景，我们描述了一位患有后部皮质萎缩的患者，他表现出明显的尾随行为。他还经历了严重的识别外部刺激的困难，包括视空间功能障碍、几种类型的认知障碍、言语理解困难、定向障碍和相关的抑郁。这种尾随行为相对于他识别周围世界的极度困难可能是一种适应。
