Abstract

We describe a peculiar contralesional drawing disorder in three patients affected by focal brain lesions, who did not show signs of unilateral neglect at standard clinical assessment, including the star cancellation test. This picture, that could be termed selective constructional hemi-apraxia (CHA), could follow both right and left-hemisphere lesions and is observed in complex constructional tasks. Future studies are warranted to explore the clinical and functional implications of CHA and its boundaries with unilateral neglect and constructional apraxia.

单侧脑损伤后选择性对侧结构性半失用症：与单侧空间忽视有何关系？

我们描述了三例局灶性脑病变患者的特殊对视绘画障碍，他们在标准临床评估中没有表现出单侧忽视的迹象，包括星星消除测试。这幅图可以被称为选择性构造半失用症（CHA），可以跟随左右半球病变，并在复杂的构造任务中观察到。未来的研究应探讨CHA的临床和功能意义及其与单侧忽视和结构性失用症的界限。

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.
