Objective: To examine the association between threatened miscarriage, and neurodevelopmental disorders, including autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) in offspring by age 14 years. Methods: We used data from the Millennium Cohort Study, a nationally representative longitudinal study of children born in…

Data from the National Survey of Children's Health 2016-2020 was used to examine the association between physical activity and anxiety and depression among autistic youth, non-autistic youth with ADHD, and non-autistic non-ADHD youth. There was a significant negative association between physical activity and anxiety among all groups. Reduction in…

Attention-deficit/hyperactivity disorder (ADHD) symptoms affect 40-60% of autistic children and have been linked to differences in adaptive behavior. It is unclear whether adaptive behavior in autistic youth is directly impacted by co-occurring ADHD symptoms or by another associated feature of both autism and ADHD, such as increased irritability.…

Purpose: Only a few studies examined the longitudinal pattern of parent-teacher reports on autism severity and comorbidities in autism spectrum disorder (ASD) and yielded conflicting results. The study's aims were to compare parents and teachers' perception of autism, attention deficit hyperactivity disorder (ADHD) and anxiety symptoms severity in…

The purpose of the current study was to use the infant sibling design to explore whether proband traits of autism and ADHD could provide information about their infant sibling's temperament. This could help us to gain information about the extent to which infant temperament traits are differentially associated with autism and ADHD traits. We used…

This study was conducted to assess this association between early life antibiotic exposure and the risk of autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) in later life. The results showed that early life antibiotic exposure was associated with an increased risk of ASD (OR = 1.13, 95% confidence interval (CI):…

High levels of parenting stress have been detected in mothers of children with Autism (ASD) and children with attention deficit hyperactivity disorder (ADHD) comparing with mothers of typically developing (TD) children. The current study explored the implications of social support (confidant and affective support) and child characteristics…

Konke, Linn Andersson; Forslund, Tommie; Nilsson-Jobs, Elisabeth; Nyström, Pär; Falck-Ytter, Terje; Brocki, Karin – Journal of Autism and Developmental Disorders, 2022
The current study investigated longitudinal associations between parent-rated temperament, observed exuberance and accelerometer activity level at 18-months and symptoms of ASD and ADHD at 36-months in a sample of 54 children at elevated likelihood for ASD. For the specific parent-rated temperament scales, most observed significant associations…

ADHD comorbidity has been associated with delayed diagnosis of ASD, but no study has investigated this association in an Asian country. Children with ASD were included and divided into three groups: ADHD before ASD, ADHD same/after ASD, and ASD only. Timing of ASD and ADHD diagnoses were assessed. The logistic regression model was performed to…

Stephens, Kate; Silk, Timothy J.; Anderson, Vicki; Hazell, Philip; Enticott, Peter G.; Sciberras, Emma – Journal of Autism and Developmental Disorders, 2021
Children with attention deficit/hyperactivity disorder (ADHD) combined with autism spectrum disorder (ASD) symptoms (ADHD + ASD) have poorer social and emotional functioning than those with ADHD alone. However, no studies have specifically examined the associations between ASD symptoms, measures of social and emotional functioning and limbic…

Ishimoto, Yuma; Yamane, Takahiro; Matsumoto, Yuki – Journal of Autism and Developmental Disorders, 2019
A large number of children with developmental disorders like autism spectrum disorder (ASD), learning disabilities, and attention deficit hyperactivity disorder have high anxiety. It has also been shown that the high anxiety has harmful effects on them, directly and indirectly. In this study, we conducted a survey on community samples on the level…

Mayes, Susan D.; Seebeck, Jyssica; Waschbusch, Daniel A. – Journal of Autism and Developmental Disorders, 2022
Relationships between sluggish cognitive tempo (SCT) and age and IQ were investigated in children with autism and/or ADHD covering broader age and IQ ranges than in previous studies. Mothers rated 1436 children with autism and 1,056 with ADHD (2-17 years, IQs 9-149) on Pediatric Behavior Scale SCT items. Increasing age correlated with SCT in the…

Many neurodevelopmental disorders (NDDs) share common learning and behavioural impairments, as well as features such as dysregulation of the oxytocin hormone. Here, we examined DNA methylation (DNAm) in the 1st intron of the oxytocin receptor gene, "OXTR," in patients with autism spectrum (ASD), attention deficit and hyperactivity (ADHD)…

Based on data from the Longitudinal Study of Australian Children linked with pharmacy dispensing data from the Australian Government's Pharmaceutical Benefits Scheme, we calculated the 1-year prevalence of psychotropic medicine supply in children and adolescents with Autism Spectrum Disorder (ASD) as reported by parents in 2014.

Shephard, Elizabeth; Tye, Charlotte; Ashwood, Karen L.; Azadi, Bahar; Asherson, Philip; Bolton, Patrick F.; McLoughlin, Grainne – Journal of Autism and Developmental Disorders, 2018
Altered power of resting-state neurophysiological activity has been associated with autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD), which commonly co-occur. We compared resting-state neurophysiological power in children with ASD, ADHD, co-occurring ASD + ADHD, and typically developing controls. Children with ASD…
