摘要

单侧空间忽略症(USN)患者无法探索或报告左侧个人和个人以外空间出现的刺激。单侧空间忽略症通常由右侧顶叶病变引起:如今,结构连接(右侧纵上筋束第二和第三分支,分别为 SLF II 和 SLF III)和功能网络(背侧和腹侧注意网络,分别为 DAN 和 VAN)在单侧空间忽略症中的关键作用也很明显。在这份多模态病例报告中,我们合并了一名右顶叶肿瘤和 USN 患者手术前的结构和功能信息。术后 6 个月,USN 自发恢复,我们也收集了患者的功能、结构和神经心理学数据。将手术前后右侧顶叶肿瘤的扩散指标和功能连接性(FC)与一名在类似位置患有肿瘤但无 USN 的患者的相同数据以及对照样本进行了比较。结果表明,与对照组相比,USN 患者手术前右侧 SLF III 受损,右侧 DAN 的 FC 降低;手术后,USN 恢复,患者的弥散指标和 FC 与对照组相比没有差异。这个单一病例及其多模态方法强化了右侧SLF III和DAN在以自我为中心和以分配为中心的人外USN的发展和恢复中的关键作用,强调了在脑部手术中保留这些结构和功能区域的必要性。

Spontaneous unilateral spatial neglect recovery after brain tumour resection: A multimodal diffusion and rs-fMRI case report

Patients with unilateral spatial neglect (USN) are unable to explore or to report stimuli presented in the left personal and extra-personal space. USN is usually caused by lesion of the right parietal lobe: nowadays, it is also clear the key role of structural connections (the second and the third branch of the right Superior Longitudinal Fasciculus, respectively, SLF II and III) and functional networks (Dorsal and Ventral Attention Network, respectively, DAN and VAN) in USN. In this multimodal case report, we have merged those structural and functional information derived from a patient with a right parietal lobe tumour and USN before surgery. Functional, structural and neuropsychological data were also collected 6 months after surgery, when the USN was spontaneously recovered. Diffusion metrics and Functional Connectivity (FC) of the right SLF and DAN, before and after surgery, were compared with the same data of a patient with a tumour in a similar location, but without USN, and with a control sample. Results indicate an impairment in the right SLF III and a reduction of FC of the right DAN in patients with USN before surgery compared to controls; after surgery, when USN was recovered, patient's diffusion metrics and FC showed no differences compared to the controls. This single case and its multimodal approach reinforce the crucial role of the right SLF III and DAN in the development and recovery of egocentric and allocentric extra-personal USN, highlighting the need to preserve these structural and functional areas during brain surgery.

期刊介绍: The Journal of Neuropsychology publishes original contributions to scientific knowledge in neuropsychology including: • clinical and research studies with neurological, psychiatric and psychological patient populations in all age groups • behavioural or pharmacological treatment regimes • cognitive experimentation and neuroimaging • multidisciplinary approach embracing areas such as developmental psychology, neurology, psychiatry, physiology, endocrinology, pharmacology and imaging science The following types of paper are invited: • papers reporting original empirical investigations • theoretical papers; provided that these are sufficiently related to empirical data • review articles, which need not be exhaustive, but which should give an interpretation of the state of research in a given field and, where appropriate, identify its clinical implications • brief reports and comments • case reports • fast-track papers (included in the issue following acceptation) reaction and rebuttals (short reactions to publications in JNP followed by an invited rebuttal of the original authors) • special issues.
