Every day in the United States, millions of expectant mothers accept a prenatal vitamin on the communication of their doctor.

The counsel typically comes with physical health in heed: folic acrid to help avert fetal spinal cord problems; iodine to spur healthy brain development; calcium to be bound like molecular Legos into atomic baby bones.

But what well-nigh a child's future mental wellness? Questions about whether ADHD might ascend a few years down the road or whether schizophrenia could crop up in young adulthood tend to be overshadowed past more than firsthand parental anxieties. Equally a friend with a newborn girl recently fretted over lunch, "I'm just trying not to drib her!"

Yet much equally pediatricians administer babyhood vaccines to baby-sit against time to come infections, some psychiatrists at present are thinking well-nigh how to shift their treatment-centric discipline toward one that also deals in early prevention.

In 2013, University of Colorado psychiatrist Robert Freedman and colleagues recruited 100 healthy, pregnant women from greater Denver to study whether giving the B vitamin choline during pregnancy would enhance encephalon growth in the developing fetus.

The momshoped-for were randomly given either a placebo or a course of choline chosen phosphatidylcholine. Choline itself is cleaved down by bacteria in the gut; by giving it in this related course the supplement tin can more effectively be absorbed into the bloodstream.

Those in the handling group received 3,600 milligrams of phosphatidylcholine in the morning and ii,700 milligrams at nighttime. Since phosphatidylcholine is roughly 13-15 pct choline, the amount the women received was about 900 milligrams of choline a day, twice that recommended past the Health and Medicine Division of the National Academies (and about the same amount independent in three large eggs).

After nascency, infants were given either 100 milligrams of liquid phosphatidylcholine or placebo once a twenty-four hours for approximately iii months. Given that both groups were too getting choline from regular feeding, the dose ensured that those supplemented received well over the Establish of Medicine's guideline that infants receive at least 125 milligrams a twenty-four hours.

At v weeks erstwhile, the children were exposed to a series of clicking sounds in the lab while their brain activity was monitored by electroencephalogram, or EEG, a method for recording electrical brain activity via electrodes placed on the scalp. Normally, when exposed to the same audio successively, both infant and adult brains will showroom "inhibition," or a far weaker pulse of action in response to the second sound. Nosotros realize that the at present familiar tone is insignificant; our brains are unmoved.

However, in some kids this inhibition doesn't occur — a finding linked with an increased gamble for attention issues, social withdrawal and, later on in life, schizophrenia.

The results published in 2013 in the American Journal of Psychiatry by Freedman's group show that 76 percent of newborns whose mothers received choline supplements had normal inhibition to the audio stimuli. The proportion fell to 43 percent in those born to mothers who didn't become them. It appeared that choline might steer the infant brain away from a developmental class that predicted mental wellness problems.

A follow-upwards report at twoscore months found that the children who had received choline supplements in utero and after nascence had fewer attention bug and less social withdrawal.

Excessive choline consumption — or that over 7,500 milligrams a twenty-four hours — has been associated with drops in blood pressure, sweating, gastrointestinal side effects and a "fishy" body odor. But well-nigh diets comprise adequate choline, and supplementation to optimal levels poses no known side furnishings or chance to fetal development, Freedman says.

A genetic theory

1 of the outset genes to be linked to schizophrenia goes by the tricky name "CHRNA7." Commonly it encodes for a receptor on neurons in the brain that reply to the neurotransmitter acetylcholine equally well as nicotine, a transmission essential to normal brain function and noesis. Genetic mutations in the CHRNA7 gene crusade decreased levels of the neuronal receptor to be produced in people with schizophrenia.

A light bulb glowed for Freedman.

And the idea, he admits, is rather uncomplicated when you think most it: Choline is known to exist essential to encephalon development and part and is also oft deficient in meaning women.

Couple these facts with beast and human research by Freedman and his colleagues showing that choline in the amniotic fluid also activates the CHRNA7 receptor in the developing fetal brain.

"Information technology occurred to us that just as folic acrid can help overcome defects in brain and spinal cord development, perhaps supplementing mothers with choline could assistance forestall mental illness," Freedman recalls. "And at present that the children in our study are over 4 years onetime, nosotros can come across that those given the supplement appear to be on a unlike developmental track, one with fewer mental problems."

Moreover, though experimental psychosis treatments targeting the CHRNA7 cistron and the receptor information technology codes for are existence explored by other researchers, Freedman explains that levels of the receptor peak in the fetal brain and diminish after birth. "We realized the optimal time to try this intervention is during pregnancy," he says.

Though choline is available in a number of foods — eggs, seafood and liver are particularly rich in the nutrient — Freedman'south work suggests that for many women, dietary sources may exist inadequate during pregnancy. Also, prenatal supplements tend not to include it.

Ii past observational studies — conducted with diet questionnaires rather than the more rigorous placebo-controlled supplementation Freedman's group tried — also found beneficial effects associated with higher maternal choline intake during pregnancy. At 7 years of age, children of moms consuming over 400 milligrams of choline a day performed better on retention and intelligence tests. At eighteen months, infants whose mothers had higher blood levels of choline had significantly college cognitive test scores.

Dr. Steve Zeisel of the Academy of Due north Carolina was i of the first doctors to strongly advocate for choline supplementation in pregnancy. In 2012, Zeisel published the only other placebo-controlled trial of the vitamin in pregnant moms. While he did not assess for future mental health risks, the findings suggested that choline supplementation did not raise infant cognitive function at 1 year of age. Yet, Freedman point outs that all of the women included in the trial were highly educated and were constitute to have blood metabolites reflecting diets high in healthful, choline-containing foods.

The prospects of choline supplementation in pregnancy have piqued medical interest, simply as well notes of caution. "I call up the choline research is really intriguing, and nosotros're starting to investigate maternal choline levels as well," says Catherine Monk, an associate professor in psychiatry and obstetrics and gynecology at Columbia University Medical Centre. "Some prenatal vitamins practise contain it and foods rich in choline are readily available. But we accept a lot more research to do earlier nosotros start recommending information technology widely."

In general, show-based interventions during pregnancy and early on babyhood to prevent mental illness are scant. Yet there are some modifiable run a risk factors that might make a departure, many of which focus on improving maternal wellbeing.

Monk'southward own research explores on the impact of an expecting mother's emotional land on the developing fetus. She and others take shown that stress, depression and feet during pregnancy increase a child's hazard for ADHD, conduct disorders and depression later in life. At Columbia, Monk and her colleagues employ a program Practical Resources for Effective Postpartum Parenting, or PREPP, in which pregnant women who are distressed and at high-risk for postpartum depression are counseled and taught coping skills to brand pregnancy and parenting more manageable emotionally.

Optimal nutrition, including choline and adequate amounts of zinc and omega-three fatty acids, may too accept developmental and mental health benefits equally might fugitive smoking.

The future of funding

Despite incomplete information on choline supplementation, Freedman's research colleague Dr. Camille Hoffman-Shuler, an obstetrician, sees it equally a promising intervention that should go along to exist explored.

"Obstetricians and midwives are not widely aware of choline supplementation," she says. "But I do recommend it to pregnant women, especially if they have other mental health vulnerabilities. And I'd personally want it with a time to come pregnancy based on existing data."

Both Freedman and Hoffman-Shuler promise to continue choline research, still decry the obstacles to securing the coin to practise it.

"The NIH is currently funding no trials of any intervention in humans during pregnancy to preclude mental illness," says Freedman, "yet ideally we'd follow these children for another 20 to 25 years to see if they develop mental illness. This is across the telescopic of near imaginable — and fundable — experiments."

Hoffman-Shuler is prepared to do what it takes. "The hardest role is getting this across to the funding agencies and the public," she says. But this is a serious public health issue in which prevention during pregnancy is far more preferable to the loss of health and consequences that come with mental illness!"
