Paracetamol use in pregnancy linked to newborn neurodevelopment risks: Study
Available over-the-counter, paracetamol -- also known as 'acetaminophen' -- is considered safe for managing headache, fever, and pain during pregnancy.
Researchers, including those at the Icahn School of Medicine at Mount Sinai, US, analysed 46 previously published studies involving over a lakh participants across multiple countries.
Findings published in the journal BioMed Central show that "higher-quality studies are more likely to show a link between prenatal acetaminophen exposure and increased risks of autism and ADHD," said author Diddier Prada, assistant professor of population health science and policy, environmental medicine and climate science, at the Icahn School of Medicine at Mount Sinai.
"Given the widespread use of this medication, even a small increase in risk could have major public health implications," Prada said.
Biological mechanisms that could explain the link between use of paracetamol and risk of disorders in children
The paper also explores biological mechanisms that could explain the association between acetaminophen use and these disorders. Acetaminophen
Paracetamol is known to cross the placental barrier and may trigger oxidative stress, disrupt hormones, and cause epigenetic (gene behaviour resulting in observable traits) changes that interfere with brain development of the foetus, the researchers explained.
With cases of autism and ADHD estimated to be on an increase the world over, the findings have significant implications for public health policy, clinical guidelines, and patient education, they said.
The team added that even as the study does not show that paracetamol causes neurodevelopmental disorders in offsprings, evidence from the study strengthens the connection and raises concerns about current clinical practices.
The authors suggested a cautious, time-limited use of paracetamol by pregnant women under medical supervision and called for more studies to confirm their findings.

7 everyday parenting habits that improve your child's mental well-being
7 parenting habits that secretly boost your child's mental health every day (Image: iStock) Even though parenting is a unique ritual, which is specific to each family with influences from personal to social to familial learnings, few learnings remain common and can be mimicked by the vast majority of parents to ensure inculcation of healthy habits in their children. According to a 2024 study, Routines and child development: A systematic review (Selman, Journal of Family Theory & Review ), consistent home routines like mealtimes and bedtime rituals are linked to fewer internalising problems (e.g., anxiety, depression), reduced externalising behaviours and even lower ADHD symptoms. Longitudinal evidence shows 'bedtime routines at age 3 predict decreased anxious, depressed, withdrawn and aggressive behaviors at age 5.' A study in Infant Behavior & Development tracked over 2,900 children and found that "children with consistent early bedtime routines were better able to regulate their emotions at age three" and that this improved emotional regulation mediated positive behavioural outcomes in fifth grade. A 1997 study by Gottman, Katz and Hooven, Parental meta-emotion philosophy, found that parents who understand and guide children's emotions ('emotion coaching') help them develop self-regulation, attention, emotional bonds and adaptability. As Gottman asserted, 'There is evidence that parents' interaction with the child has implications for the child's ability to self-regulate, focus attention, share intersubjective meaning and be able to interact with a changing environment. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Benefits of Trading Bitcoin CFDs IC Markets Learn More Undo ' In an interview with TOI, Dr Kushal Agrawal, HOD - Department of Neonatology and Paediatrics at KVR Hospital in Kashipur, suggested seven tips to meaningfully support your child's mental health and emotional growth - Encourage open emotional communication Daily parenting habits that are scientifically proven to boost kids' well-being (Image: iStock) Openly sharing emotions is one of the most effective methods to develop resilience. When children can recognise and name their emotions, they are better able to manage them. Tip: Create a safe, judgment-free space at home where your child can talk about both positive and challenging feelings. Just make sure that you impress upon the child that it is OKAY to share everything. Teach problem-solving skills According to research, children who learn problem-solving skills at a young age we can boost their feeling of autonomy and resilience. Tip: When your youngster encounters a problem, avoid rushing in to solve it. Motivate your kid to at least attempt to solve it on their own. Demonstrating resilience in everyday life Children generally learn through observation, particularly from their parents. Keeping a calm and positive attitude when facing your own struggles can have a significant impact on your child's capacity to cope with stress. Tip: Though it is okay for your kid to share their feelings, you don't need to share your frustrations and insecurities in details as they have to learn resilience from you. Practice mindfulness together Mindfulness has been demonstrated to alleviate anxiety and improve emotional regulation in youngsters. Mindfulness enables children to focus on the present moment, which allows them to better manage overwhelming emotions and feelings. Tip: Try easy mindfulness exercises as a family. Share everyday moments of thankfulness or practice deep breathing together. Establish strong social connections Parenting reset: Daily habits that transform your child's mental well-being (Image: iStock) Supportive relationships with family, friends and trusted adults are essential for over all development. Tip: Arrange playdates, join community groups, or enrol your child in team sports or clubs. These activities create opportunities for kids to learn how to work in groups. Encourage positive self-talk Children gain immensely from learning how to replace negative thoughts with positive self-affirmation. According to studies, youngsters who use positive self-talk feel more confident and are less likely to experience self-doubt. Tip: Encourage them to repeat positive affirmations in front of mirror everyday at set time, say while brushing Promote physical health for emotional strength Regular physical activity has been related to a better mood, less stress, and increased resilience. Physical activity gives a productive outlet for energy, promotes general health, and improves mental well-being. Tip: Plan family activities like walking, biking, or playing sports. Encourage your child to engage in physical activities they enjoy, which can become a positive coping mechanism for managing stress.

ADHD Medicines Reduce Suicide, Crime Risks In Sweeping Study
Drugs to treat attention deficit hyperactivity disorder were linked to a reduced risk of suicidal behavior, substance misuse and criminality in the first research of its kind. The findings come amid increasing debate around whether ADHD is being over-diagnosed and therefore over-treated with drugs like Ritalin. The research published in the British Medical Journal on Wednesday did not investigate whether patients are being accurately diagnosed, but it does provide evidence supporting medical treatment. ADHD is characterized by difficulties with concentration and impulse control. Roughly 5% of children and 2.5% of adults are estimated to have the condition, which is also associated with an increased risk of substance misuse and self-harm. The researchers wanted to test whether the risk changed with medication. The study design was meant to closely mirror a randomized clinical trial, considered the gold standard of research. The scientists looked at health registry data from almost 150,000 patients newly diagnosed with ADHD in Sweden. At a two-year follow-up, they found that patients taking medicine had a 17% reduction in suicidal behavior and a 15% drop in substance misuse. They also found declines in the risk for criminality and transport accidents. When looking at the recurrence of these behaviors, there were also benefits linked to the medication. While the trial cannot show direct causation and could be confounded by factors such as ADHD severity, it provides doctors with vital evidence showing that drugs can address and reduce important risks, according to one of the authors. "These data should inform clinical guidelines, policies and current debates," said Samuele Cortese, a professor of child and adolescent psychiatry at the University of Southampton. The benefit was greater for patients taking stimulant medications than non-stimulants in the study. Stimulants include drugs like Novartis AG's Ritalin, while non-stimulants include Eli Lilly & Co.'s Strattera. The study results echo other similar conclusions, but "the large sample size, use of a national registry, and more sophisticated analysis give greater confidence in these results that findings aren't explained by something else other than medication use," said Adam Guastella, a clinical psychologist who works at Sydney Children's Hospital at Westmead and the University of Sydney's Brain and Mind Center. He was not involved in the research. Prescriptions in England for ADHD medicines have increased 18% year on year since the Covid-19 pandemic, according to research published in the BMJ Mental Health this year. The surge is believed to be linked to greater awareness of the condition.
