Study proves ‘baby brain’ in expectant mums

IT is official, scientists say the dreaded “baby brain” is real.

Pregnant women have long complained of forgetfulness and poor concentration, but many dismissed the phenomenon as an old wives tale.

A Victorian university has uncovered evidence of changes to women’s brains during pregnancy with the big- gest differences detected in the third trimester.

Up to 80 per cent of pregnant women report a decline in memory, difficulty reading, confusion, poor concentration and absent-mindedness and reduced motor co-ordination.

The Deakin University meta-analysis of 20 studies, including more than 1000 women, was the largest study of its kind.

Lead author Linda Byrne said the research showed general cognitive functioning, memory and executive functioning were significantly lower than non-pregnant women.

Associate Professor Byrne reassured expectant mothers that baby brain should not be a cause for concern.

“Pregnant women already stressed and enough to worry about . . . and we certainly don’t want to add to that,” she said.

“Despite the differences, pregnant women were still performing within the normal range.”

There is evidence suggesting the phenomenon is a form of “biological priming” that prepares the woman to devote all of her attention to the child when it is born.

It may also be as a result of the physical transformations a women is experiencing, fatigue and the contemplation of a major life change.

Kate Hutchison, who gave birth to her second baby last week, said she “definitely” experienced baby brain.

“I noticed at work I was not as switched on and there were a few repeat emails sent,” the 33-year-old said.

Like many mothers, she is keen to know if the symptoms resolve or persist, and if so, how long after the baby is born.

Prof Byrne said more research was needed to understand the impact, which they hoped to answer in a study currently under way.

It is using neuroscience techniques to track changes in cognition before, during and after pregnancy.
