空间忽视是对侧空间中注意力、感知和刺激处理的障碍。异质行为涉及不同的神经解剖学机制。轶事证据表明,主动空间感知的神经回路可能与用于编码空间记忆的神经回路不同。这些差异可能会逃避传统评估的检测,从而导致漏诊。我们提出一个案例,一位艺术家在活跃的空间感知过程中表现出对侧空间的选择性损伤。当要求完全凭记忆绘画时,他的表现更好。该案例凸显了忽视的可变性、全面测试的重要性,并鼓励进一步调查。
Spatial neglect is a disorder of attention, perception, and processing of stimuli in contralesional space. The heterogeneous behaviors involve diverse neuroanatomical mechanisms. Anecdotal evidence suggests that neural circuitry of active spatial perception may differ from that used to encode spatial memory. These differences can escape detection by conventional assessments, thereby leading to missed diagnoses. We present a case, in an artist who demonstrates selective impairment in a contralesional space during active Where spatial perception. His performance is better when asked to draw entirely from memory. This case highlights the variability in neglect, importance for comprehensive testing, and encourages further investigation.
