n. 脑白质营养不良;[内科] 脑白质病变
Leukodystrophy is not an independent disease, but a general name of a group of genetic diseases with myelination or maintains disorder which often happens in children.
脑白质营养不良并非一个独立的疾病,而是一组最常见于儿童的髓鞘形成或维持发生障碍的遗传性疾病的总称。
Insufficient or poorly working myelin causes a number of diseases, including a rare and fatal congenital disorder called pediatric leukodystrophy that affects thousands of children.
髓磷脂不足或工作状态差可导致一系列疾病,包括影响几千个孩子的一种罕见与致命的遗传病:小儿脑白质营养不良。
Abnormal enhancement is not seen in PMD as opposed to some demyelinating disorders such as adrenal leukodystrophy in which enhancement is seen at the periphery of the active demyelination.
PMD中不会有异常的强化,相反其他的脱髓鞘病变如肾上腺脑白质营养不良症其外周活动性的脱髓鞘病变可以强化。
脑白质营养不良(Leukodystrophy)是一组罕见的遗传性神经系统疾病,主要特征为脑白质的发育异常或进行性退化。脑白质由神经纤维的髓鞘组成,其功能类似于“绝缘层”,确保神经信号高效传递。当基因突变导致髓鞘合成、维持或代谢异常时,神经信号传导受阻,引发多系统功能障碍。

leukodystrophy(脑白质营养不良)的详细解释如下:
指一组遗传性神经退行性疾病,主要因髓鞘(包裹神经纤维的脂质层)代谢异常导致脑白质逐渐受损。这种损伤会影响神经信号传递,引发运动和认知功能退化 。
