Baby brain or busy brain?

To all the mums out there, it’s not just you!

Earlier this year, a group of researchers at Deakin University confirmed that ‘baby brain’ is a real thing. Now they want to know if baby brain is unique to pregnant women, and they need our help to answer that question.

Anyone who juggles the daycare / kinder / school / toddler-tired kid-teen tantrums and tries to find some space in their life for things like education, work, or even just rest could attest that baby brain tends to turn into mummy brain and daddy brain and probably even childminding grandparent brain. Or is the absentmindedness, and drops in concentration and memory not the influence of the small people at all? Is it because it’s a big change in our lives and these issues are symptomatic of life disruptions in general – such as moving house, separating or divorcing, loss or change of a job?

What is beyond question is that the baby brain effect is real. The science is in. Which would be music to the ears of a former publisher who, while I was pregnant with my first child, thought he was being kind thing when he explained (yes ladies, man-splained) that many otherwise intelligent and capable women become scattered and a bit mentally erratic when they are pregnant. He had observed this in fellow scientists when he worked in laboratories. He suggested I take more notes… Lovely.

Having put the baby brain question to bed, so to speak, lead researcher Sasha Davies, a PhD candidate in Deakin’s School of Psychology, is now investigating the underlying drivers of baby brain. 

“What our original meta-analysis showed was that women do experience some cognitive changes during pregnancy, with impacts to memory and attention,” she said.

“But we also know that having a baby is a major life event, and mums-to-be can be affected by all sorts of factors like sleep deprivation and stress. What we’re now aiming to quantify is how much these cognitive changes are also found in people who aren’t pregnant but may be going through other big life changes, such as a relationship breakdown, changes to employment, or moving to a new city.”

To gather this data Ms Davies and her supervisor Dr Melissa Hayden, a Senior Lecturer in Deakin’s School of Psychology, have developed an anonymous online survey, open to Australians aged between 18 and 45. The 30 minute questionnaire asks about life events, and then gets participants to complete some simple cognitive tasks.

Alongside this online survey, the team are also recruiting women to take part in a more in-depth cross-sectional study to further unpack the underlying brain-based reasons why some of the cognitive changes found in pregnant women may be occurring.

“In our original study we found that the cognitive changes were most noticeable in the third trimester,” Ms Davies said.

“So, we’ll be comparing pregnant women in their third trimester, with women who have never been pregnant, using some behavioural testing and also an electroencephalogram, which records electrical patterns in the brain.”

Dr Hayden said it was important to emphasise that the reality of baby brain was confined to minor memory or attention lapses that would typically only be noticed by the pregnant woman herself, or her partner.

“Of course we hear plenty of anecdotal evidence where women say they start forgetting things during pregnancy – they put the car keys in the fridge or miss appointments,” she said.

“But you could argue many of us experience similar memory or concentration lapses when we’re distracted or stressed, without being pregnant. So, there’s no need to ring any alarm bells here. What we want to do is simply better understand how women’s bodies and brains change during pregnancy, so we can support the health of expectant mothers in the best possible way.”

Dr Hayden said a recently published study in the Netherlands indicated there may even be some advantages to baby brain, with potential improvements to social brain functioning.

“So, we certainly don’t think it’s just a deficit, but that it’s probably part of a far bigger picture,” she said.
