Study finds ‘pregnancy brain’ is real, and strengthens mother’s bond with baby

Scientists say the commonly used term ‘baby brain’ during pregnancy may reflect real biological changes that help mothers bond more strongly with their babies.

Researchers in Spain found that a pregnant woman’s brain undergoes measurable changes, particularly in the grey matter.

Brain changes during pregnancy

According to the scientists, grey matter — the part of the brain responsible for processing emotions and empathy — decreases by about 5% during pregnancy.

While that might sound negative, researchers say the change appears to have a purpose.

Instead of weakening emotional connection, the shift may actually strengthen it.

“They’re saying it makes you more empathetic. It makes you more able to bond with your baby,” explained 702/CapeTalk world news correspondent Vicki Turner.

Stronger emotional connection with babies

Scientists also found that the amount of grey matter reduction may be linked to how strongly a mother bonds with her child.

“The more grey matter that women lose, the bigger the bond with the child,” the research explanation said.

Researchers suggest the change should not be seen as a loss of brain ability.

Instead, they compare it to pruning a tree.

“When you prune it, it grows back stronger,” the explanation said.

A new set of skills for mothers

Scientists say the brain changes during pregnancy may help mothers return with what they describe as a “whole new set of skills”.

The adjustments may improve empathy and emotional responsiveness, helping mothers better connect with and care for their babies.
