Antidepressants during pregnancy can affect baby's brain health, finds study
Mothers using antidepressants during pregnancy may cause anxiety disorders in their children later in life because the drugs can interfere with the normal development of the foetal brain, a study has found.
US doctors have called for more research on the long-term impact of selective serotonin reuptake inhibitors (SSRIs) after finding babies exposed to the drugs in the womb developed differently.
The widely used antidepressants are a key tool in treating depression and are becoming more common in pregnancy as they can help prevent maternal suicides – the leading cause of death among women in their first year after giving birth.
But using advanced MRI techniques the researchers found two parts of the brain, the right amygdala and right insula, were larger and more connected in newborns whose mothers were given SSRIs than those whose mothers had untreated depression, or who were depression free.
These changes are important, the authors say in a paper published today in the JAMA Neurology journal, because “abnormalities in the amygdala-insula circuitry may be associated with anxiety and depression”.
The team, led by doctors at the Department of Psychiatry at Columbia University Medical Centre, New York, scanned 98 infants for the research.
Sixteen of the babies had mothers whose depression had been treated with SSRIs during their pregnancy, 21 infants had mothers with untreated depression and the remaining 61 had mothers with no history of depression.
They conclude that the differences in brain size and connectivity between the SSRI group and the other two are most likely to be caused by the drugs disrupting the levels of the chemical serotonin at key parts of the brain’s development.
Serotonin is a major neurotransmitter which sends messages between nerve cells in the brain and other parts of the body, and plays a major role in mood, the sleep-wake cycle and constricting of muscles in the gut.
Studies have shown SSRI use becoming more common in treating maternal depression, rising in one US treatment area from 5.7 per cent of pregnancies in 1999 to 13.4 per cent in 2003, but there is limited understanding of their effects.
The authors conclude that because untreated depression “poses risks to both the infant and mother” the decision on when and how long to use them is a “clinical dilemma” for psychiatrists.
While they were able to show brain changes the authors say future studies should look at any increased risk of depressive, cognitive or movement abnormalities later in life for these infants – as this information could help resolve the treatment dilemma.
Independent academics said the findings were the first to show such a link and warranted further investigation; however, they said there were other limitations to the study that could also contribute to these changes.
Andrew Whitelaw, emeritus professor of neonatal medicine at the University of Bristol said differences in the socioeconomic backgrounds of the mothers was significant in the study.
The majority (75 per cent) of those receiving SSRIs were white, well educated and well off, while 61 per cent of the non-SSRI depressed group were earning less than $25,000 (£17,700) a year and only 14 per cent were white: differences which could impact upon the other stresses the children faced during pregnancy and in later childhood.
But, he added: “The current findings are original and build on previous research in Finland showing that SSRI-treated mothers have children with an increase in depression in adolescence.
“Wisely, the authors do not conclude that SSRI treatment should be avoided in pregnancy. Untreated depression in pregnancy has serious risks for mother and baby and psychiatrists have the difficult task of identifying the pregnant women where SSRI treatment is the least risky decision.”

Babies at risk of being put in unsafe sleep positions by babysitters
Babies who died in their sleep while being watched by someone other than parents were often placed in unsafe sleep positions, a study has found.
Researchers examined more than 10,000 infant deaths from 2004 to 2014 and found that 1,375 cases (13.1%) occurred during the absence of a parent. They found infants who died of sleep-related causes under non-parental supervision were less likely to be placed in the “supine” position - lying horizontally with their face and torso facing up.
Among the babies who died under non-parental supervision, those supervised by relatives or friends were more often placed on an adult bed or couch for sleep and were more likely to have objects in their sleep environment. The researchers urged paediatricians to educate parents that all caregivers must always follow safe sleep practices.
“If someone else - a babysitter, relative, or friend - is taking care of your baby, please make sure they know to place your baby on the back in a crib and without any bedding,” said Dr. Rachel Moon of the University of Virginia School of Medicine.
Dr Moon added: “It’s always best to discuss where and how your baby should sleep. You can’t make assumptions that the person with whom your baby is staying will know what is safest.”
So if you’re leaving your baby with a family member or friend for the first time, what should you ensure they know before you leave the house?
Kate Holmes, support and information manager at The Lullaby Trust told HuffPost UK: “Whether caring for your own baby, or babysitting a friend or relative’s little one, it’s important that you’re aware of the risks of sudden infant death syndrome (SIDS). While SIDS is rare, it’s important that anyone taking care of an infant knows the safer sleep practices that reduce the chance of SIDS occurring.”
The Lullaby Trust advised that parent should make sure all babysitters are aware to:
:: Place the baby on his or her back.
:: Put the baby (if aged 0-6 months) to sleep in their own cot or Moses basket in the same room as where you are for both day and night-time sleeps.
:: Avoid letting the baby get too hot.
:: Don’t cover the baby’s face while sleeping or use loose bedding.
:: Keep cot as clear as possible, with no pillows, duvets, cot bumpers, soft toys or baby products.
The charity suggested parents could pass on their Easy Read cards that encourage safer sleep.
Pregnancy: Week By Week
This week begins with your menstrual bleeding or period. You are not pregnant yet. Cycle day 1 is the first day of menstrual bleeding. Ovulation and fertilization happen at the end of next week.
At the end of week 2, the sperm meets the egg on the day of ovulation in a process called fertilization. Pregnancy begins when the embryo implants, about 6-12 days after ovulation/fertilization.
The fertilized egg moves down through the fallopian tube towards the uterus. Implantation happens on average 9 days after ovulation/fertilization.
Week 4 is a very eventful week. The embryo will travel through the fallopian tube, arrive in the uterus and implant on average 9 days after fertilization/ovulation. And within days after implantation, the pregnancy test will be positive!
Now things are moving along quickly in the growth process. The blastocyst now consists of three layers. The innermost layer or endoderm is where the intestine, bladder, pancreas, and liver will form.
Your baby has grown from 1/17 of an inch to 1/3 of an inch. While your baby may still be very small, many of the crucial organs are developing rapidly. Arms and legs are growing, but fingers and toes have yet to sprout.
You are now more than halfway through the first trimester, and the baby continues to grow rapidly. Last week, baby measured 1/3 of an inch and now he has grown to 3/4 of an inch in length. The heart is beating and if an ultrasound is performed, a fluttering will be seen on screen.
Cartilage is now forming and bones are growing. Baby is forming the skeleton that he will use to stand, walk and run later in life. Eye structure is progressing and the tongue is beginning to develop. Intestines have formed in the umbilical cord, but are now moving out of the cord and into baby’s abdomen.
Growth has reached a crucial point by week 10 and you may see fetal movements on ultrasound. The movements are very small, but they are quite important. With joints fully developed, baby needs to move to ensure everything is working properly.
At the start of the 11th week, baby is now officially called a fetus. The most crucial development phases are concluding. The fetus now must concentrate on growing longer and larger during the next 29 weeks. Growth is fast now and the fetus will gain about one inch in length during the 11th week alone.
The 12th week starts a new day for the fetus. Growth speed is increasing exponentially and formed organs are starting to practice the functions they will have outside of the womb. The intestines, for example, start practicing peristalsis. Peristalsis is the muscle movement of the intestines that helps during digestion.
The 13th week concludes the first trimester. The alien look of an early fetus on ultrasound is disappearing as the eyes move closer together and the ears shift to their normal location. The gender could be viewed if an ultrasound could see that far into the womb.
Welcome to your 2nd trimester of pregnancy! At this point in growth, an ultrasound would show movement in the chest area. This movement is breathing practice. Hands and feet are moving now too, though most of the movements are reflex.
By the 15th week of pregnancy, some parents are itching to find out the sex of baby. In utero, the fetus may be sucking the thumb or fingers. The suck reflex is one of the most important instincts a baby has, because without the suck reflex, babies cannot breastfeed or bottle feed effectively.
By the start of the 4th month, pregnant women tend to start feeling movements in the abdomen. Intially, it may only feel like flutters but the fetal bones are hardening now so movements that have been occurring for weeks can now be felt.
The fetus is continuing to grow faster than ever before. All reflexes are in place so the fetus can suck, swallow and blink. The heart is pumping vigorously and can pump more than 25 quarts of blood on any given day.
Bowel development continues and the first bowel movement, meconium, is developing inside. Baby will not pass the first movement until after birth, in most cases. The fingers and toes are developing pads and soon fingerprints will form. The boy fetus is developing the prostate gland during week 18 of pregnancy.
Lanugo, or fine hair, has been growing on baby’s skin since the 15th to 16th week. During week 19, vernix caseosa starts to develop. Vernix caseosa is a thin white covering that protects the skin from the fluid environment of the amniotic sac.
The 20th week marks the halfway point for a normal pregnancy. Growth continues to add length and weigh to the baby. By the 20th week, baby can weigh more than one pound and measure 8 inches or longer. Fetal growth is determined by many factors, so baby may grow more quickly for some pregnant women and more slowly for others.
This week marks a slight slowing of the growth process. The fetus continues to grow, but more attention is paid to internal organs and development than weight gain. Length does not slow as rapidly, so the fetus may take on an extremely thin façade for a while. Male fetuses begin to drop the testes during week 21.
The fetal brain growth continues daily. The sense of smell, taste, sight, hearing, and touch are all developing as well. Baby can suck, swallow and hear. What is the fetus hearing? Heartbeats, breathing, and digestion. These sounds are like lullabies to the baby, which may be why babies tend to be more comfortable laying on mom’s tummy than dad’s tummy for a while after birth.
This week marks a huge milestone for the fetus. Development has reached the point that the fetus could conceivably survive if an early birth was required. The risk factors for impaired neonatal health are high, and survival, though very low, is a tangible reality. Baby will sleep and wake, though maybe not on the same cycle as mom.Week 24
Now the fetus is usually considered "viable" in the U.S. by most doctors. That means it has a reasonable chance of surviving if born prematurely. During the 24th week, the fetus continues to gain good weight. Weighing in at more than 1 1/3 pounds, your baby is gaining weight thanks to bone development, muscle growth, and organ growth.
The spine continues to strengthen in the 25th week of pregnancy. When complete, the spine will be made up of 1000 ligaments, 150 joints, and 33 rings. The process seems complicated, but the female body has all the instructions down pat. Lungs also continue to grow with blood vessel winding through lung tissue. The nostrils have been closed to this point, but now they start to open just a bit.
The fetus continues to grow rapidly and weighs about two pounds and measures nine inches or more by the 26th pregnancy week. The air sacs of the lungs are starting to develop and the surfactant is being secreted to line the air sacs. Surfactant is necessary for normal lung function. The brain is also working hard as hearing and vision are developing this week.
This is another huge landmark in pregnancy. It is the last week of the second trimester. The baby's brain is quickly developing and the lungs continue to prepare for breathing air once the baby is born. Eyelids open and retinas develop this week as well.
Welcome to your 3rd trimester! The 28th week of gestation is the start of the 7th month and the third trimester. The fetus is growing by leaps and bounds and has a 90% chance of survival if born during this week. The lungs can breathe air, though some development is still needed to fully function properly outside the womb. Body fat increases to 2-3% this week. Your baby can weigh more than two pounds by the end of the week.
The fetus is finally starting to look like a baby. The head and body are proportionate at this time. Weight gain is rapid as fat stores continue to build under the skin. Eyes are completely developed and are now sensitive to light. Fetuses are now able to hear, see and smell. Women that are pregnant with multiples have the same milestones this week though singlets may soon outweigh multiples.
Fetal growth continues and baby weighs three pounds or more and continues to gain weight daily. Bones have developed and bone marrow has started producing red blood cells. The white covering over the skin, lanugo, is starting to fade away in preparation for birth. Hearing has developed to the point that the fetus recognizes certain voices. Both mom and dad can talk to baby, sing and laugh. These sounds do not have to be directed at the belly for baby to hear.
Fetal growth is beginning to slow down a bit. As space tightens, the baby develops at a slower rate. All necessary body functions are working perfectly, time spent in the uterus at this point is all about lung development and weight gain.
All five senses are now in full working order. The fetus can see, taste, smell, feel and hear. Hair continues to grow, though some babies will be born with much more than others. Weight gain slows down a bit, especially for women pregnant with multiples. Between weeks 32 and 40, multiple fetuses will steadily gain less weight than singlets.
Amniotic fluid levels reach an all-time high. Fluid levels will remain the same until the baby is born. Fetal skin starts out red, but changes to pink in the latter weeks of pregnancy. The color change is attributed to fat distributions under the skin. More fat means pinker skin.
Brain development is rapid and thus the size of the head is growing to hold new brain tissue. Brain development accounts for the growth of about 3/8 of an inch each week.
The fetus weighs in at more than 5 ½ pounds by the 35th week. This number is just an average as some babies are born full term weighing only 5 1/2 pounds. There is very little room left in the uterus, so when baby moves the pregnant woman will feel it. It is common to visibly see movement through the skin of the abdomen from time to time including kicking, punching and rolling.
It's just four weeks to go until the due date. During the next few weeks, the weight of baby will shift downward relieving some of the shortness of breath associated with the upward growth of the uterus. While this can leave a pregnant woman feeling as if she has enough wind to run a marathon, the relief comes at a price. That marathon will be run to and from the bathroom. The downshift in weight leaves very little space for storage in the bladder. The baby continues to collect fat with dimpling starting on knees and elbows.
The 37th and 38th weeks of pregnancy are considered early term. Pregnant women who make it to the 37th week no longer have to worry about delivering the baby early. The fetus weighs around 6 1/2 pounds and practices breathing during every waking moment. An ultrasound will actually show fetal breathing movements which often confuses parents. Baby is not really breathing, as there is no air in the uterus.
If baby measures too large at an ultrasound in the 38th week, the doctor may choose to induce labor to protect the health of the pregnant woman and baby. Meconium is also developing in the bowel of the fetus. When the bag of waters breaks, it should be clear. If meconium appears in the amniotic fluid, you will be monitored more closely and labor will be sped along as quickly as possible.
Good things come to those who wait. And if you are scheduled for a cesarean section, either because you previously had a cesarean section or for other reasons, chances are that it will be done in the 39th or 40th pregnancy week or later.
Time is up! With 40 weeks of the pregnancy behind you, many pregnant women feel the time to have the baby is NOW! Predicting birth dates is an inexact science. There is a give of two weeks before and after the estimated date of birth. A pregnancy is not considered overdue until after the 42nd week. Rest assured, however, the baby is now fully-grown and ready to safely exist outside the womb.
By now, most pregnant women are ready to give birth. Fatigue, pain, swelling and abdominal weight alone are enough to keep women in bed until labor pains begin. For the fetus, week 41 is nothing more than an extended vacation. The fetus will continue to store fat and practice breathing throughout the 41st week. As long as the placenta is in good working order and amniotic fluid levels are good, the baby is fine.
In most pregnancies, the baby will have been born by the 42nd pregnancy week. With every passing day, the chance of having a vaginal birth diminishes, especially for pregnant women with narrow hips. If the baby has not moved into the birth canal, C-section may be the best option.
