家门钥匙又找不着了？那个人叫什么名字来着？哎呀，那个路牌没看见！生活中，常常可见到这样一些粗心大意、丢三落四的人。不过，这或许不能全怪他们，最新研究显示，基因在其中扮演了重要角色。 德国波恩大学的研究人员发现，大脑额叶中负责信号传输的一种名为 DRD2 的基因与健忘、注意力不集中有紧密联系。 研究人员随机选取了 500 名受访者，让他们评价自己平时是否注意力集中、是否健忘，并通过他们的唾液样本

家门钥匙又找不着了？那个人叫什么名字来着？哎呀，那个路牌没看见！生活中，常常可见到这样一些粗心大意、丢三落四的人。不过，这或许不能全怪他们，最新研究显示，基因在其中扮演了重要角色。

德国波恩大学的研究人员发现，大脑额叶中负责信号传输的一种名为 DRD2 的基因与健忘、注意力不集中有紧密联系。

研究人员随机选取了 500 名受访者，让他们评价自己平时是否注意力集中、是否健忘，并通过他们的唾液样本进行基因检测。结果发现， DRD2 基因有两个变体，拥有该基因一个变体的志愿者更容易出现注意力分散，记忆力较差的情况，且这种健忘常具有家族遗传性。

研究人员表示，即便注意力不集中、记忆力较差与遗传有关，也不代表人们对此没有任何办法。例如，这些丢三落四的人可以将要做的事情写在便签纸上，或尽量把家门钥匙放在同一个地方。
