Baby Brain: What's Really Going On?

Forgetfulness, brain fog, the inability to focus - baby brain is a concept many mums can relate to. But what鈥檚 really going on inside the brains of mums-to-be? We go inside the world鈥檚 largest study.

We鈥檝e all heard the cliche 鈥� that pregnancy makes women somehow more forgetful and less capable. But scientists behind the world鈥檚 largest study scanning pregnant women鈥檚 brains say it鈥檚 time to rethink the trope.

They鈥檝e found that women鈥檚 brains change profoundly during pregnancy, with grey matter volume decreasing significantly.

But a leading neuroscientist in the field tells us this reduction isn't necessarily a bad thing. In fact, the evidence suggests the changes are for good.

We go inside the latest science and talk to leading researchers, as well as mothers, to ask the question 鈥� what鈥檚 really going on?
