The consequences of alcohol drinking during pregnancy are dramatic and usually referred to as fetal alcohol spectrum disorders (FASD). This condition is one of the main causes of intellectual disability in Western countries. The immature fetal brain exposed to ethanol undergoes massive neuron death. However, the same mechanisms leading to cell death can also be responsible for changes of developmental plasticity. As a consequence of such a maladaptive plasticity, the functional damage to central nervous system structures is amplified and leads to permanent sequelae. Here we review the literature dealing with experimental FASD, focusing on the alterations of the cerebral cortex. We propose that the reciprocal interaction between cell death and maladaptive plasticity represents the main pathogenetic mechanism of the alcohol-induced damage to the developing brain.
怀孕期间饮酒的后果是显著的,通常被称为胎儿酒精谱系障碍(FASD)。这种情况是西方国家智力残疾的主要原因之一。暴露于乙醇的未成熟胎儿大脑会经历大量神经元死亡。然而,导致细胞死亡的相同机制也可能导致发育可塑性的变化。由于这种适应不良的可塑性,中枢神经系统结构的功能损伤被放大,并导致永久性后遗症。在这里,我们回顾了关于实验性 FASD 的文献,重点介绍了大脑皮层的改变。我们提出,细胞死亡和适应不良的可塑性之间的相互作用代表了酒精对发育中大脑损伤的主要发病机制。
