Just when a pregnant woman might need to multitask, research has confirmed that the long-suspected "baby brain" effect kicks in, as suspected, and may impair memory for up to a year after birth.

怀孕的女人本就需要身兼多职，而研究却证实长久以来流传的“孕傻”说法是真的，怀孕会造成准妈妈记忆力衰退，其影响力甚至会波及到产后一年。

Studies showed that up to 80 percent of women reported impaired cognitive ability, particularly increased forgetfulness. The cause is not known, and theories include hormonal changes and sleep deprivation.

研究显示多达80%的女性报告说自己怀孕后认知能力下降了，特别是健忘越来越严重。原因尚不明了，有理论称“孕傻”是由体内荷尔蒙变化和缺觉引起的。
