Nat Neurosci:一孕傻三年?核磁共振表示:你想多了!

我们常听人说一孕傻三年,意思是当女性怀孕后,记忆力会有衰退的迹象,常常丢三落四,通常我们叫此为“孕傻”或“婴儿脑”状态。不过,这种说法有科学依据吗?

之前有很多关于怀孕对认知功能的研究,但基本都是从激素的角度来解释怀孕的影响,以人脑为观测对象开展深入研究,此前几乎没有先例。

灰质、海马体减少,然后呢?

前不久,荷兰莱顿大学神经学家Elseline Hoekzema等在Nature 的子刊Neuroscience上发表了一项研究成果,希望改变这种局面。

Hoekzem等人使用磁共振成像技术,对初次怀孕并生育的25名女性进行脑部扫描:首先是怀孕前,然后是在其生完孩子3周和几个月后。

为了排除其他因素的干扰,研究人员还对20名未怀孕且未生育过孩子的女性,19名初为人父和17名没有孩子的男性进行了脑部扫描。

然后,研究人员开始利用计算机对磁共振扫描结果进行灰质分析。

他们发现,无论是自然受孕还是体外受精而怀孕,只有初为人母者才会出现灰质减少的现象。

这难道就是“一孕傻三年”的证据?没那么简单!

灰质体积萎缩不代表着这会导致孕妇智商和记忆力的降低。该研究也没有发现怀孕妇女和未怀孕妇女在记忆上有明显的差异。

原来,虽然怀孕期间宝妈大脑中处理及回应社交信号的区域灰质面积有所缩减,但其实这并不是坏事,该部分区域与妈妈们生产后响应自己宝宝需求的区域几乎重合,这表明,脑结构的这种变化,或许是为了让初为人母者脑相关区域能更高效地运作,以更好地回应宝宝的需求并及时察觉到周围环境中的威胁因素。

事实上,通过磁共振成像扫描,再利用计算机进行分析,可以百分之百地判定女性是否怀孕过。

除了灰质的变化,怀孕期间主要负责记忆的海马体也会产生类似的变化,并且,这些变化至少会持续两年。看起来跟“一孕傻三年”在时间上倒是很接近嘛。

在后续的跟踪研究中,Hoekzem等人发现,两年后,参与实验的25位母亲中的11位,在没有再次受孕的情况下,其脑部磁共振成像扫描结果显示,她们孕期失去的灰质并没有补回来,而海马体基本恢复。

脑容量下降,认知水平下降?

除了灰质和海马体变化容易引起误会外,对于怀孕对认知的影响,人们可能还存在很多的理解误区。

比如:英国的奥特利基博士和他的同事们研究发现,女性孕期脑容量会降低4%,这个发现经常会被误认为是变“傻了”的证据。

实际上我们要清楚,脑细胞的记忆功能并不是由脑容量起决定性作用的,而是由代表记忆作用的神经细胞起决定作用的。

另外,美国科学家格林也曾做过对比试验:选择254名孕产妇和48名未曾生育的女性,分阶段测试了她们的记忆力。结果发现,孕产妇在听声音记词的测试中略处下风,但在记数列和人脸的测试中两组女性不分高下。

这个研究结果充分显示无论在短期还是长期的认知水平上,怀孕并不会给女性带来明显变化。

以上的研究结果都不能表明怀孕会变傻,所以,宝妈们和家里有宝妈的,不贸然否定,不跟风盲从,才是科学的魅力。
