我们介绍F.G.的情况，一名健康、发育正常的22岁男性受试者，患有环境定向和导航方面的广泛性障碍，没有神经或精神疾病史。神经放射学检查显示没有证据表明大脑的解剖或结构改变。我们提交了一个全面的神经心理学评估的地形定向参与不同的认知过程，以评估他的空间环境导航的能力，结果证实了严重的发展地形障碍和缺陷的一些特定的认知过程中直接或间接参与导航。参考先前描述的发育地形定向障碍的唯一情况（Pt 1; Iaria等人，2009年）。F.G.与前一种情况不同，原因如下：他的障碍更严重，他完全缺乏导航技能，未能发展补偿策略，以及在处理整体部分之间的空间关系方面存在特定缺陷。本病例不仅证实了发育性地形技能障碍的存在，也揭示了地形过程的结构及其在人类中的发展。(C)2010爱思唯尔有限公司保留所有权利。
We present the case of F.G., a healthy, normally developed 22-year-old male subject affected by a pervasive disorder in environmental orientation and navigation who presents no history of neurological or psychiatric disease. A neuro-radiological examination showed no evidence of anatomical or structural alterations to the brain. We submitted the subject for a comprehensive neuropsychological assessment of the different cognitive processes involved in topographical orientation to evaluate his ability to navigate the spatial environment.The results confirmed a severe developmental topographical disorder and deficits in a number of specific cognitive processes directly or indirectly involved in navigation. The results are discussed with reference to the sole previously described case of developmental topographical disorientation (Pt1; Iaria et al., 2009). F.G. differs from the former case due to the following: the greater severity of his disorder, his complete lack of navigational skills, the failure to develop compensatory strategies, and the presence of a specific deficit in processing the spatial relationships between the parts of a whole.The present case not only confirms the existence of developmental topographical-skill disorders, but also sheds light on the architecture of topographical processes and their development in human beings.
