Abstract

Marchiafava-Bignami disease (MBD) is a rare complication of chronic alcoholism that typically causes demyelination and necrosis of the corpus callosum. Here, we report a man with probable MBD with callosal and right medial paracentral lesions who presented with abnormal reaching behavior and ideomotor apraxia of the left hand. He exhibited difficulty in reaching with the left hand when a target object was placed on his right-hand side, and he exhibited rightward bias when using his right hand in a line bisection task. These disturbances in reaching suggest disruption of the top-down control of motor intention and spatial attention at the corpus callosum.

一例疑似马尔基亚法瓦-比格纳米病患者的运动意向与空间注意的脱节。

Marchiafava Bignami病（MBD）是一种罕见的慢性酒精中毒并发症，通常会导致胼胝体脱髓鞘和坏死。在这里，我们报告了一名可能患有MBD的男子，他患有胼胝体和右内侧中央旁病变，表现为异常的伸手行为和左手视运动失用症。当目标物体放在他的右手边时，他表现出左手难以够到，而当他在平分线任务中使用右手时，他也表现出向右偏。这些触达障碍表明胼胝体自上而下的运动意图和空间注意力控制被破坏。

期刊介绍： Cognitive and Behavioral Neurology (CBN) is a forum for advances in the neurologic understanding and possible treatment of human disorders that affect thinking, learning, memory, communication, and behavior. As an incubator for innovations in these fields, CBN helps transform theory into practice. The journal serves clinical research, patient care, education, and professional advancement. The journal welcomes contributions from neurology, cognitive neuroscience, neuropsychology, neuropsychiatry, and other relevant fields. The editors particularly encourage review articles (including reviews of clinical practice), experimental and observational case reports, instructional articles for interested students and professionals in other fields, and innovative articles that do not fit neatly into any category. Also welcome are therapeutic trials and other experimental and observational studies, brief reports, first-person accounts of neurologic experiences, position papers, hypotheses, opinion papers, commentaries, historical perspectives, and book reviews.
