I always wonder about claims like this from both sides. I see people claiming pregnancy alters a woman's brain, miscarriages can cause postpartum depression, but then see claims that abortions do not effect the brain at all. The third I find hard to believe given the first two. And I know this is a touchy topic, but I am pro-choice yet find it a bit baffling that we ignore some of the science behind its effects on the brain and moods. Hormones are very powerful. If you are on either side of that fence, I think we can all agree that we want the woman to be well. I feel like writing off effects for political reasons does nothing but damage women (I think this is more U.S. than other countries.) Especially if we consider some women getting abortions are doing so for socio-economic reasons. If their brains are effected (they become depressed,) that is hurting their social standing even more. If we can identify that as a possible effect, then we can treat them.
A bit of a tangent, but it's something reading this prompted me to rant about.
