Pregnancy brain is a term used to describe forgetfulness during pregnancy, not being able to focus, or brain fog. This can also extend to after birth, and you may have heard people blame mommy brain or momnesia. Anecdotally, pregnancy brain and mom brain are very common. The standard answer to why this happens is that you are short on sleep, you have a lot going on, and you are dealing with additional stress. This is all true, but it may not fully explain why we get pregnancy brain from a scientific standpoint.

This article examines the science behind pregnancy brain and explores some evidence that it may actually make you a better parent.
