Heightened Anxiety and Depression among Autistic Adolescents with ADHD: Findings from the National Survey of Children's Health 2016-2019
Peer reviewed Peer reviewed
Direct linkDirect link
Amy L. Accardo; Nancy M. H. Pontes; Manuel C. F. Pontes – Journal of Autism and Developmental Disorders, 2024
Data from the National Survey of Children's Health 2016-2019 was used to examine the co-occurrence of autism and ADHD and the impact on anxiety and depression among adolescents age 12-17. Rates of anxiety and depression were up to ten-fold the prevalence of adolescents not diagnosed with autism or ADHD. Over half of autistic females (57%) and…

Brief Report: Sensory Features Associated with Autism after Controlling for ADHD Symptoms
Peer reviewed Peer reviewed
Direct linkDirect link
Ellen C. Masters; Kevin M. Antshel; Wendy R. Kates; Natalie Russo – Journal of Autism and Developmental Disorders, 2025
Background: Sensory processing differences are reported both in children with ADHD and in children with autism. Given the substantial overlap between autism and ADHD, the current study examined which sensory features were uniquely predictive of autistic traits after controlling for ADHD symptoms, age, IQ, and sex in a sample of children and…

Rebecca M. Pollak; T. Lindsey Burrell; Joseph F. Cubells; Cheryl Klaiman; Melissa M. Murphy; Celine A. Saulnier; Elaine F. Walker; Stormi Pulver White; Jennifer G. Mulle – Journal of Autism and Developmental Disorders, 2024
3q29 deletion syndrome (3q29del) is associated with neuropsychiatric and neurodevelopmental phenotypes. We previously reported that graphomotor weakness is present in up to 78% of individuals with 3q29del. We have now explored nuances of the graphomotor phenotype and its association with other comorbidities in this population. Participants were…

Quicker Exogenous Orienting and Slower Endogenous Orienting in Autistic People

Shuting Li; Keitaro Machida; Emma L. Burrows; Katherine A. Johnson – Journal of Autism and Developmental Disorders, 2025
Research is equivocal on whether attention orienting is atypical in autism. This study investigated two types of attention orienting in autistic people and accounted for the potential confounders of alerting level, co-occurring symptoms of attention-deficit/hyperactivity disorder (ADHD) and anxiety, age, and sex. Twenty-seven autistic participants…

Effects of Intersectionality along the Pathway to Diagnosis for Autistic Children with and without Co-Occurring Attention Deficit Hyperactivity Disorder in a Nationally-Representative Sample
Peer reviewed Peer reviewed

Miller, Haylie L.; Thomi, Morgan; Patterson, Rita M.; Nandy, Karabi – Journal of Autism and Developmental Disorders, 2023
Children with complex behavioral profiles (e.g., ASD + ADHD) may experience delays in obtaining a final diagnosis. Low-resource or underrepresented groups may be at even greater risk for delayed diagnosis. We assessed the effect of sociodemographic factors, symptom complexity and co-occurring conditions, and identifier of first symptoms on…

Factor Structure of Repetitive Behaviors across Autism Spectrum Disorder and Attention-Deficit/Hyperactivity Disorder
Peer reviewed Peer reviewed

Brierley, Noah J.; McDonnell, Christina G.; Parks, Kaitlyn M. A.; Schulz, Samantha E.; Dalal, Tyler C.; Kelley, Elizabeth; Anagnostou, Evdokia; Nicolson, Robert; Georgiades, Stelios; Crosbie, Jennifer; Schachar, Russell; Liu, Xudong; Stevenson, Ryan A. – Journal of Autism and Developmental Disorders, 2021
Restricted interests and repetitive behaviors (RRBs) are core symptoms of autism spectrum disorder (ASD), and commonly occur in attention-deficit/hyperactivity disorder (ADHD). Little is known about how RRBs manifest in ADHD. We quantified and compared factor structures of RRBs in children with ASD (n = 634) or ADHD (n = 448), and related factors…

DNA Methylation of the Oxytocin Receptor across Neurodevelopmental Disorders
Peer reviewed Peer reviewed

Siu, Michelle T.; Goodman, Sarah J.; Yellan, Isaac; Butcher, Darci T.; Jangjoo, Maryam; Grafodatskaya, Daria; Rajendram, Rageen; Lou, Youliang; Zhang, Rujun; Zhao, Chunhua; Nicolson, Rob; Georgiades, Stelios; Szatmari, Peter; Scherer, Stephen W.; Roberts, Wendy; Anagnostou, Evdokia; Weksberg, Rosanna – Journal of Autism and Developmental Disorders, 2021
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)…

Presentation and Correlates of Hoarding Behaviors in Children with Autism Spectrum Disorders and Comorbid Anxiety or Obsessive-Compulsive Symptoms
Peer reviewed Peer reviewed

La Buissonnière-Ariza, Valérie; Wood, Jeffrey J.; Kendall, Philip C.; McBride, Nicole M.; Cepeda, Sandra L.; Small, Brent J.; Lewin, Adam B.; Kerns, Connor; Storch, Eric A. – Journal of Autism and Developmental Disorders, 2018
We investigated the presentation and correlates of hoarding behaviors in 204 children aged 7-13 with autism spectrum disorder (ASD) and comorbid anxiety or obsessive-compulsive disorder (OCD) symptoms. Approximately 34% of the sample presented at least moderate levels, and with 7% presenting severe to extreme levels of hoarding. Child gender…

Sex Differences in Co-Occurring Conditions among Autistic Children and Youth in Florida: A Retrospective Cohort Study (2012-2019)

Angell, Amber M.; Deavenport-Saman, Alexis; Yin, Larry; Zou, Baiming; Bai, Chen; Varma, Deepthi; Solomon, Olga – Journal of Autism and Developmental Disorders, 2021
Autistic children have a high prevalence of co-occurring mental health, developmental/behavioral, and medical conditions, but research on sex/gender differences has been mixed. We used Florida healthcare claims data to characterize sex differences (female/male) in co-occurring conditions among autistic children ages 1-21 (N = 83,500). After…

2D:4D Ratio in Neurodevelopmental Disorders: A Twin Study
Peer reviewed Peer reviewed

Myers, Lynnea; van't Westeinde, Annelies; Kuja-Halkola, Ralf; Tammimies, Kristiina; Bölte, Sven – Journal of Autism and Developmental Disorders, 2018
The second to fourth digit (2D:4D) ratio is of interest in autism spectrum disorder (ASD). Studies on the relationship of this ratio with other neurodevelopmental disorders (NDDs) are lacking. Investigating the association between the ratio and NDDs in twins can provide insight into genetic and/or environmental factors driving the ratio. Hand…

van Steijn, Daphne J.; Oerlemans, Anoek M.; van Aken, Marcel A. G.; Buitelaar, Jan K.; Rommelse, Nanda N. J. – Journal of Autism and Developmental Disorders, 2013
Few studies have examined the influence of parental ASD and ADHD symptoms in combination with child pathology on the parent- child relationship as perceived by the child. A sample of 132 families was recruited with one child with ASD (with/without ADHD), and one unaffected sibling. Affected children (regardless of diagnosis) reported lower…
