Genetic Predisposition Influences Screen Time in Children with ASD and ADHD
A recent study conducted by Nagoya University Graduate School of Medicine in Japan has shed light on the relationship between screen time and neurodevelopmental disorders, such as autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) in children. This research, published in the journal Psychiatry Research, reveals intriguing insights into how genetic predisposition may influence screen time habits.
Screen time, which refers to the hours spent on digital devices like smartphones, computers, televisions, and gaming systems, has been a growing concern in today’s tech-savvy world. The study examined 437 children’s DNA, evaluating a staggering 6.5 million polymorphisms to identify genetic susceptibility to ASD and ADHD. By calculating a “polygenic risk score,” which factors in the genetic variations associated with these disorders, researchers aimed to discern a potential link between genetics and screen time.
The study’s findings are notable. Children with a higher genetic susceptibility to ASD were found to spend more time on screen devices from a young age, with some using screens for as long as 3 to 4+ hours a day. Similarly, children with a heightened genetic risk of ADHD tended to gradually increase their screen time as they grew older.
Dr. Nagahide Takahashi, the lead researcher at Nagoya University, emphasized that screen time might not be a cause of ASD or ADHD, as previously suggested. Instead, he proposed that it could serve as an early sign of these conditions, as children with ASD may be more drawn to objects than people.
Dr. Takahashi also cautioned against excessive screen exposure for children with ADHD, given the prevalence of gaming addiction. He stressed the importance of parents and caregivers monitoring screen time and intervening before it becomes a problem.
These findings could offer valuable insights for parents and caregivers of children with neurodevelopmental disorders. Dr. Takahashi suggested that, rather than feeling guilty or facing criticism for allowing screen time, parents should seek help and explore alternative behavioral management strategies. By recognizing the potential genetic factors at play, caregivers can develop more effective child-rearing approaches to support children with ASD and ADHD.
