IT SEEMS pregnancy brain really does exist – as scans shed mild on exactly how distinguished having a baby can change the brain.
Changes can linger for years after birth and very most realistic a few areas of the brain remain untouched, the first “map” of the technique suggests.

Scientists took 26 MRI scans of a 38-year-customary woman’s brain before plan, all thru her pregnancy and till two years after childbirth.
The findings show that some parts of the human brain may shrink in dimension all thru pregnancy, however change into higher linked.
A few areas of the brain remain untouched by the transition to motherhood, the watch published in Nature Neuroscience suggests.
Probably the most changes may be permanent, as the brain essentially reorganises itself all thru pregnancy, experts urged.

Researchers said the findings, based on brain scans from one mum, may characterize certainly one of many first comprehensive maps of changes within the organ before, all thru and after pregnancy.
“It’s the first detailed map of the human brain across gestation,” Emily Jacobs, of the University of California, Santa Barbara, advised the BBC.
“We’ve never witnessed the brain in a process of metamorphosis like this.
“We are finally able to watch changes to the brain in real time.”
Laura Pritschet, from the University of California, and colleagues analysed the brain of scientist Elizabeth Chrastil who was planning an IVF pregnancy when the research was being discussed.
She now has a four-year-old son.
Researches conducted 26 MRI scans and blood tests three weeks before conception and up to two years after Dr Chrastil – also one of the study authors – gave birth.
She was not made aware of the findings until afterwards.
The resulting scans were compared to brain changes in eight people who were not pregnant.
Researchers observed that the volume of grey matter – tissue that controls movement, emotions and memory – in nearly 80 per cent of the regions of Dr Chrastil’s brain decreased by about 4 per cent, with only a small rebound after pregnancy.
But there were increases in white-matter integrity – a measure of the health and quality of connections between brain regions – in the first and second trimesters, which returned to normal levels soon after birth.
The changes are similar to those during puberty, the researchers said.
Both changes coincided with rising levels of the hormones estradiol and progesterone.
According to the study, some of the changes in the brain were still present two years postpartum, including some of the shrinking, while others returned to similar levels as pre-conception by around two months after the birth.
‘What’s normal during pregnancy and what isn’t’ boxout
Your body can undergo a number of changes while you’re pregnant and it’s very common to experience some of the following symptoms:
- Constipation
- Cramps in your muscles and feet
- Back pain or headaches
- Bleeding gums
- Peeing a lot or experiencing incontinence
- Skin and hair changes
- Varicose veins
The NHS advised you call your midwife or GP immediately if you experience vaginal bleeding.
And though morning sickness is common, the NHS also urged that you contact your GP, midwife or 111 if you’re vomiting and:
- Have very dark-coloured urine or have not had a pee in more than 8 hours
- Are unable to keep food or fluids down for 24 hours
- Feel severely weak, dizzy or faint when standing up
- Have tummy (abdominal) pain
- Have a high temperature
- Vomit blood
- Have lost weight
Increased vaginal discharge can also be common, but you should get help if it smells strange or unpleasant, if its green or yellow and if you feel itchy or sore around your vagina
Nearly 85 per cent of women become pregnant at least once, and 140 million women each year become pregnant.
The physical changes to the body during pregnancy are well documented, but much less is understood about how and why the brain changes.
Mums may talk about having “pregnancy brain” or “baby brain”, to describe feeling forgetful, absent-minded or having brain fog.
Previous studies have focused on brain scans before and soon after pregnancy, rather than throughout the process.
Dr Chrastil said: “From a form of a subjective standpoint, I did no longer particularly feel any utterly different all thru pregnancy.
“Some people talk about ‘mummy brain’, or things like that, and I didn’t really experience any of that.
“However clearly we know that there are these changes.”
She added that as a neuroscientist, it was “cool” to be able to contribute to science in this way
Emily Jacobs, of the University of California, Santa Barbara, said: “There is so distinguished about the neurobiology of pregnancy that we manufacture now no longer understand yet, and it is now no longer because females are too complicated. It be now no longer because pregnancy is some Gordian knot.
“It’s a by-product of the fact that the biomedical sciences has historically ignored women’s health.
“It be 2024 and this is the first leer we have at this fascinating neurobiological transition.
“Our ignorance has consequences.

“Scientists manufacture now no longer have the data we have to predict postpartum depression before it manifests, we manufacture now no longer have the data we have to understand the effects of pre-eclampsia on later existence brain health. We want higher data.”
The researchers hope that further scans and study could help shed light on conditions like postnatal depression, pre-eclampsia, brain ageing and why pregnancy can reduce migraines.
