A recent study conducted by researchers at Edith Cowan University has shed new light on the potential link between gestational diabetes and attention-deficit/hyperactivity disorder (ADHD) in children. The findings, which analyzed data from over 200,000 mother-child pairs across Europe and Australia, suggest that children born to mothers who experienced gestational diabetes during pregnancy are more likely to develop ADHD and exhibit externalizing behaviors.

The research, led by Dr. Rachelle Pretorius and Professor Rae-Chi Huang, focused on the symptoms of ADHD in children aged 7-10 years. The results showed that those born to mothers with gestational diabetes had consistently higher ADHD symptoms compared to their peers. Moreover, children aged 4-6 years who were exposed to gestational diabetes exhibited more externalizing problems, such as hyperactivity, impulsivity, defiance, or aggression.

Dr. Pretorius explained that externalizing symptoms are behaviors directed outward, rather than internal emotional struggles like depression or anxiety. These symptoms often coexist with ADHD and tend to emerge before medical intervention, particularly during early childhood.

Professor Huang noted that the exact mechanisms by which gestational diabetes influences child development remain unclear. However, research suggests that acute and chronic maternal inflammation during pregnancy may impact certain pathways in a child’s brain programming, contributing to neurodevelopmental outcomes like ADHD symptoms.

The study’s findings have significant implications for our understanding of the potential long-term effects of gestational diabetes on child health. While more research is needed to fully elucidate these relationships, the results emphasize the importance of monitoring and managing gestational diabetes during pregnancy to minimize its impact on child development.

In conclusion, the link between gestational diabetes and ADHD in children is a complex issue that requires further investigation. As researchers continue to explore this connection, it is essential to provide support and resources for families affected by gestational diabetes and ADHD, ensuring that these children receive the care they need to thrive.

New Study Investigates Effects of ADHD Medications on the Heart: Small Increases Found in Blood Pressure and Pulse

A recent study led by the University of Southampton has shed light on the effects of Attention-Deficit/Hyperactivity Disorder (ADHD) medications on the heart. The research, published in The Lancet Psychiatry, analyzed data from 102 randomized controlled trials involving over 22,700 participants with ADHD.

The study found that while there were some concerns about the side effects of these medications, the benefits of taking them outweighed the risks. In fact, the researchers discovered an overall small increase in blood pressure and pulse for most children taking ADHD medications.

Professor Samuele Cortese, senior lead author of the study from the University of Southampton, emphasized that when it comes to taking any medication, risks and benefits should always be assessed together. He noted that other studies have shown clear benefits in terms of reductions in mortality risk and improvement in academic functions, as well as a small increased risk of hypertension.

The researchers used an advanced statistical approach called network meta-analysis to compare the effects of several medications. They found that all ADHD medications were generally associated with overall small effects on blood pressure, heart rate, and ECG parameters. With the exception of guanfacine, which leads to decreased blood pressure and heart rate, other medications led to increases in these values.

Interestingly, no significant differences were found between stimulants (including methylphenidate and amphetamine) and non-stimulants (atomoxetine and viloxazine) with regard to their effects on blood pressure and heart rate. This suggests that both types of medications should be monitored for cardiovascular side effects.

Dr. Luis Farhat, first author of the study from the University of São Paulo in Brazil, stressed the importance of careful monitoring of blood pressure and heart rate, particularly for practitioners who might assume that only stimulants have a negative effect on the cardiovascular system.

Professor Cortese concluded by saying that while their findings are informative at the group level, they cannot exclude that some individuals may be more vulnerable to cardiovascular side effects. He emphasized that efforts based on precision medicine approaches will hopefully provide important insights in the future.

Overall, this study provides valuable information for healthcare professionals and families of children with ADHD who are considering medication as a treatment option. By understanding the potential cardiovascular risks associated with these medications, they can make informed decisions about the best course of action for their child’s health.

The human experience of perceiving color has long been a topic of interest in psychology and neuroscience, with researchers seeking to understand how our subjective experiences relate to physical brain activity. However, studying conscious experiences in children has posed a significant challenge due to their limited language abilities.

To address this gap, a team of researchers at Kyoto University developed a methodology for evaluating conscious experiences, or qualia, in young children. Focusing on their experience with color, the team created a touch panel interface that requires minimal language skills, making it accessible to children as young as 3 years old.

“We were motivated by fundamental questions about how children perceive and experience the world,” says corresponding author Yusuke Moriguchi. He highlights that there was no established methodology to evaluate these experiences in young children who cannot fully articulate their perceptions.

Using their newly-developed interface, the researchers chose nine distinct colors and asked participants to rate color similarities on a four-point scale from “very similar” to “very dissimilar.” The study included Japanese children aged 3-12 and Chinese children aged 6-8, along with Japanese adults. They also conducted the tests in different environments, both online and in-person, and utilized either a computer or a touch screen for each test.

The results revealed that young children experience colors in nearly the same way as adults, and that the structure of how children experience colors remains remarkably consistent across age groups and cultures. The researchers observed slight age-related differences for certain color combinations, as children’s judgments gradually came to resemble adult patterns as they grow older.

“We were surprised to observe the consistency of color qualia structures across ages, despite known significant changes in children’s understanding and use of color names with age,” says Moriguchi. The researchers also did not expect the experimental environment to have such minimal influence on the results, which demonstrates the robustness of their approach.

Further studies that involve children from more diverse cultural backgrounds and that utilize more colors are necessary. However, these findings suggest that the human color experience may transcend age and culture, and also unlocks new possibilities for studying subjective experiences across developmental stages.

“Our study provides a new methodology for scientifically investigating conscious experiences in young children,” continues Moriguchi. This could contribute to developing better parenting and educational approaches based on children’s perspectives, and a better understanding in general of how children perceive the world around them.
