Low vitamin D at birth may raise risk of ADHD, autism, and Schizophrenia: study

Arab Times21-05-2025

NEW YORK, May 21: A large study involving The University of Queensland has found that newborn babies with low vitamin D levels are more likely to develop mental health conditions such as ADHD, schizophrenia, and autism later in life.
Researchers looked at the vitamin D levels of 71,793 people, many of whom were diagnosed with mental disorders during childhood or early adulthood. This is the biggest study of its kind.
Professor John McGrath from UQ's Queensland Brain Institute led the research, which was done in partnership with Aarhus University and the State Serum Institute in Denmark. The team studied six mental health conditions: major depression, bipolar disorder, schizophrenia, ADHD, autism spectrum disorder (ASD), and anorexia.
'We found that babies with lower levels of vitamin D had a higher risk of developing schizophrenia, ADHD, and autism,' Professor McGrath said.
Previous studies had already suggested a link between low vitamin D at birth and both schizophrenia and autism. This new research looked at more mental health conditions and also used two vitamin D-related markers and genetic data for a deeper analysis.
Professor McGrath said the findings support the idea that giving vitamin D supplements to pregnant women and babies might help lower the chances of mental illness later in life.
'Vitamin D is very important for a baby's brain development, and many pregnant women around the world have low levels of it,' he said. 'That's why vitamin D supplements are already recommended during pregnancy in many countries.'
He compared this to the way folate supplements are used during pregnancy to prevent birth defects like spina bifida. 'In the same way, our study suggests that making sure babies have enough vitamin D could reduce the risk of several mental health problems.'
The research used data from the iPSYCH study, which began in Denmark in 2012 to explore mental health issues. Vitamin D comes mainly from sunlight, but it can also be found in some foods and supplements.
The study results were published in The Lancet Psychiatry. Funding came from the Danish National Research Foundation, the Queensland Centre for Mental Health Research, and the University of Queensland.

Rise in diagnoses is prompting more US adults to ask: 'Do I have ADHD?'

NEW YORK, Jan 28, (AP): Allison Burk's teenage daughter struggled with uncontrolled emotions, a shrinking attention span and a growing tendency to procrastinate. A family doctor suggested ADHD testing, which led to an unexpected discovery: The teen had ADHD, and Burk did too. During her daughter's evaluation, Burk thought, "Wait a minute. This sounds familiar," she recalled. "I was able to piece together that this might be something I was experiencing,' said Burk, of Columbus, Ohio. She subsequently underwent her own testing and was diagnosed with ADHD - at age 42. More adults are being diagnosed with attention-deficit/hyperactivity disorder. Diagnoses have been rising for decades but seem to have accelerated in the last few years. A recent study suggested that more than 15 million U.S. adults - roughly 1 in 17 - have been diagnosed with ADHD. The condition always starts in childhood, but about half of adults with it are diagnosed when they are 18 or older. Some doctors say the number of people coming in for evaluation is skyrocketing. "Just in our clinic, requests for assessments have doubled in the last two years,' said Justin Barterian, a psychologist based at Ohio State University. Here's a look at the phenomenon, and how to know if you might have the condition. ADHD makes it hard for people to pay attention and control impulsive behaviors. It can be inherited, and is often treated with drugs, behavioral therapy, or both. "It's like there's an engine in you and you feel like it's always running, and you can't turn it off except with medication,' said Judy Sandler, a 62-year-old Maine woman who was diagnosed in her 50s. ADHD has been called the most commonly diagnosed mental health disorder in U.S. children, with more than 7 million kids diagnosed. Historically, it was thought to mainly affect boys (perhaps because boys with ADHD were seen as more disruptive in school) and to be something that kids grew out of. But experts believe many people aren't diagnosed as kids and live with symptoms into adulthood. Adults with the condition talk about having trouble focusing on tasks, juggling responsibilities, and planning and managing their time. Some talk about not putting things away, and straining personal relationships with their restlessness, mood swings and impulsiveness. Burk said she was grouped with talented and gifted students in grade school but didn't complete college until her 30s because, "when I was 19, I hitchhiked across the country on a whim' and ended up a single mother in her early 20s. She now works in marketing and media relations for Ohio State University's College of Veterinary Medicine. Diagnoses have been climbing in both kids and adults, and the recent government report found adult ADHD was more common than earlier estimates. "We haven't had (federal) adult ADHD data in a long time,' said one of the study's authors, Angelika Claussen of the Centers for Disease Control and Prevention. There were indicators of the rise, she added. Increasing demand for ADHD medication led to widespread shortages after the COVID-19 pandemic hit in March 2020. A 2023 study showed the rise in prescriptions was particularly notable in adults - especially women. ADHD diagnoses and prescriptions were increasing before the pandemic, due partly to a change in general diagnostic criteria in 2013 that broadened the definition of ADHD and reduced the number of symptoms a patient needed to have. But case counts really seemed to jump in 2020, when schools were closed and many adults were forced to work from home. "It's very difficult to focus when you are home and you have kids,' Claussen said. "That may have exacerbated the symptoms for people who'd had mild ADHD but were able to cope' before the pandemic. The last few years have seen growing cultural acceptance and curiosity about the condition, fueled by a proliferation of "I have ADHD' social media videos and online medical start-up companies offering 5-minute diagnostic quizzes. Indeed, the long-held belief that ADHD was underdiagnosed in adults has given way to recent debates about whether it's become overdiagnosed. There's no blood test or brain scan for ADHD. Experts say it is diagnosed when symptoms are severe enough to cause ongoing problems in more than one area of life, and when those symptoms can be traced to pre-adolescent childhood. Ideally, a psychologist or psychiatrist diagnoses it by taking careful histories from patients and from people who know them, experts say. They also might ask patients to take tests designed to check their memory and ability to concentrate. Doctors also must rule out anxiety, depression and other conditions that can have similar symptoms. But getting an appointment with a mental health professional can take months, and intensive ADHD evaluations can cost thousands of dollars. Many patients turn to family doctors or even online diagnostic quizzes, some of them connected to telehealth companies that prescribe medications. "There is wide variability in this country in how people diagnose, how strict they are, and who they diagnose,' said Margaret Sibley, a University of Washington psychologist. The American Professional Society of ADHD and Related Disorders is drafting a first national set of diagnosis and treatment guidelines for health professionals who treat adults, and expects to release them later this year. The goal is "to improve the accuracy of diagnoses in this country," said Sibley, who is leading the work on the guidelines.

Common drugs taken by pregnant women linked to autism risk in children

LONDON, Jan 4: Anti-inflammatory drugs, commonly used by millions of pregnant women worldwide, may increase the risk of autism in their babies, according to a new study. The research focused on the effects of glucocorticoids, a class of steroids, on children who were exposed to these drugs in the womb. It found that babies exposed to glucocorticoids had a 30 to 50 percent higher chance of being diagnosed with autism compared to those whose mothers did not take the drugs. The study also linked glucocorticoid exposure to an increased risk of intellectual disabilities, Attention-deficit/hyperactivity disorder (ADHD), and anxiety in children. Glucocorticoids, which include medications like prednisone and cortisone, mimic the hormone cortisol, produced by the adrenal gland, known for its anti-inflammatory effects. These steroids are often prescribed to pregnant women at risk of preterm birth because they assist in fetal organ development and maturation. Additionally, they are used to treat pregnant women with autoimmune or inflammatory conditions, such as rheumatoid arthritis, lupus, and asthma, as they help suppress the immune response. However, the study suggests that excessive exposure to glucocorticoids during pregnancy may negatively impact brain development in the fetus. It is estimated that two to three percent of the population are currently prescribed glucocorticoids, with the most common drugs in the US being prednisone, triamcinolone acetonide, and methylprednisolone. Betamethasone and dexamethasone, which can cross the placenta, are typically used for women at risk of preterm delivery and are usually administered through injections. While side effects from long-term glucocorticoid use, such as weight gain and osteoporosis, have been known for decades, the latest research from Denmark suggests these drugs could also harm the developing brain of babies. The study examined the development of more than 1 million infants born between 1996 and 2016, with over 300,000 of them exposed to glucocorticoids in the womb. Some of the women in the study received steroids to prevent preterm birth, while most were treated for autoimmune or inflammatory conditions. Researchers followed the children for 15 years, reviewing their medical histories to determine how prenatal glucocorticoid exposure affected their development. The findings revealed that children born to mothers at risk of preterm birth who took glucocorticoids were 50 percent more likely to be diagnosed with autism compared to those whose mothers were not exposed to the drugs. The risk of intellectual disabilities and ADHD was 30 percent higher in the exposed group, and the likelihood of developing mood, anxiety, and stress-related disorders was 50 percent higher. For children of mothers with autoimmune or inflammatory conditions, the study found a 30 percent higher risk of autism and ADHD in the exposed group. Additionally, the risk of mood disorders and intellectual disabilities was 40 percent higher. The researchers conclude that their data supports "continued caution" in the use of glucocorticoids during pregnancy. They suggest that alternative medications might be safer for pregnant women with autoimmune or inflammatory conditions, though they emphasize the need for further research to evaluate these options.
