AI Article Synopsis

  • - The research conducted a systematic review to analyze the relationship between Bisphenol A (BPA) exposure and ADHD in children, using strict PRISMA guidelines and quality assessment tools.
  • - Out of over 10,000 articles screened, only 46 met the criteria for inclusion, revealing that most studies did not establish a clear link between BPA and ADHD, showing high bias and low certainty.
  • - The findings suggest that there is insufficient evidence to conclude that BPA impacts ADHD, highlighting the need for future studies to address confounding factors and improve sampling techniques.

Article Abstract

Numerous studies have investigated environmental risk factors in ADHD, and Bisphenol A (BPA), an endocrine disruptor, is suspected by several reviews. However, the quality of the studies has never been carefully assessed, leading us to rigorously examine associations between BPA exposure and ADHD and associated symptoms in children. Using PRISMA criteria, we conducted a systematic review on the MEDLINE/PubMed, Web of Science, EBSCOhost, PsycINFO, PsycARTICLES and Cochrane databases. We used the ROBINS-E tool to assess the quality, and the GRADE Approach. This study was registered with PROSPERO, CRD42023377150. Out of 10446 screened articles, 46 were included. Unlike pre-existing reviews, most studies failed to find clear links with ADHD or associated symptoms, with a high risk of bias and a very low level of certainty. Our systematic review reveals insufficient evidence regarding the impact of BPA on ADHD, despite some behavioral results that cannot be generalized. Future studies will require improved consideration of confounding factors and more precise sampling methods. This study did not receive specific funding.

Children and adolescents with neurodevelopmental disorders such as autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) may be more susceptible to early life stress compared to their neurotypical peers. This increased susceptibility may be linked to regionally-specific changes in the striatum and amygdala, brain regions sensitive to stress and critical for shaping maladaptive behavioural responses. This study examined early life stress and its impact on striatal and amygdala development in 62 children and adolescents (35 males, mean age = 10.

Background: Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental outcome among children with a history of early institutional care. Prior research on institutionalized children suggested that accelerated physical growth in childhood is a risk factor for ADHD outcomes.

Methods: The current study examined physical and neurophysiological growth trajectories among institutionalized children randomized to foster care treatment (n = 59) or care as usual (n = 54), and never institutionalized children (n = 64) enrolled in the Bucharest Early Intervention Project (NCT00747396, clinicaltrials.

Background: Early in life, behavioral and cognitive traits associated with risk for developing a psychiatric condition are broad and undifferentiated. As children develop, these traits differentiate into characteristic clusters of symptoms and behaviors that ultimately form the basis of diagnostic categories. Understanding this differentiation process - in the context of genetic risk for psychiatric conditions, which is highly generalized - can improve early detection and intervention.

Background: Brain intraparenchymal schwannoma is a rare clinical entity, generally curable with adequate resection.

Methods And Results: We describe a case in a male patient first presenting at 19 months of age, the youngest reported age for this lesion. It also appears to be the first case connected to a germline TSC2 p.

Background: Most previous studies have focused on the clinical efficacy after intervention of ESDM, particularly in core symptoms. However, only a few have paid attention to the effectiveness of ESDM on emotional dysregulation and behavior problems in children with ASD. This study aimed to explore the effect of the ESDM on addressing emotional dysregulation and behavior problems in children with ASD in China, as well as its correlation with core symptoms of ASD.
