一孕为什么会傻三年?孕妇该如何“自救”

Pregnancy alters woman's brain 'for at least two years'

初次怀孕对女性大脑的影响“至少持续两年”

When the brains of 25 first-time mothers were scanned soon after they had become pregnant and again after they had given birth, "substantial" reductions in the volume of grey matter were revealed.

当25名首次怀孕的母亲在怀孕后接受大脑扫描,并在生完孩子后再次接受大脑扫描之后发现,大脑灰质的体积“显著”减少。

Pregnant women have often complained of brain fog and poor memory, but researchers at Leiden University in the Netherlands and the Autonomous University of Barcelona say that rather than indicating a simple loss of mental capacity or intelligence, the changes represent a pruning and refinement of brain circuits.

孕妇经常抱怨脑雾(熟悉清晰的事情变得模糊起来)、记忆力差,但荷兰莱顿大学和巴塞罗那自治大学的研究人员表示,这些变化并不是简单的心智能力或智力的丧失,而是代表着大脑回路被修剪和细化。

They say the changes largely affect areas of the brain associated with the ability to attribute thoughts and feelings to oneself and other people, and could help women adapt to motherhood by recognising threats to their baby or anticipating the child's needs.

他们表示,这些变化在很大程度上影响了大脑中与将想法和感受归为自己和他人的能力相关的区域,通过意识到对婴儿的威胁或预测孩子的需求,可以帮助女性适应做母亲的生活。

Parts of the brain where grey matter had been pruned lit up on MRI scans when mothers saw pictures of their own babies. The brains of first-time fathers did not show such changes in structure.

通过核磁共振成像扫描发现,当母亲们看到自己孩子的照片时,大脑中灰质被修剪的部分被激活。第一次做父亲的人的大脑结构没有出现这样的变化。
