Background: Fetal life and infancy might be critical periods for brain development leading to increased risks of neurocognitive disorders and psychopathology later in life. We examined the associations of fetal and infant weight growth patterns and birth characteristics with behavior and cognitive outcomes at the age of 13 years. Methods:…

Thirty to 80% of children with autism spectrum disorder also have symptoms of attention-deficit hyperactivity disorder. Many children with autism spectrum disorder and attention-deficit hyperactivity disorder experience difficulties carrying out goal-directed behaviors, particularly when it comes to inhibiting responses.

Previous studies have established the relationship between behavioral problems and specific learning disorders (SLD); however, the exact mechanism by which behavioral disorders impact SLD remains unclear. This longitudinal study used the Child Behavior Checklist (CBCL) to investigate how parents' judgment of children's behavioral problems changed…

The mediators of real-world executive functions in autism during the transition into adulthood are mainly unknown.

The study comprised eighteen 5-year-old boys with…

Adults with autism spectrum disorder often experience co-occurring mental health problems such as attention-deficit/hyperactivity-disorder, as well as impairments in executive function. Sluggish cognitive tempo, a cluster of behaviors including slow processing, daydreaming, and mental fogginess, has been shown to be associated with…

There are few studies of behavior problems in preterm children prior to 2 years old and the changes that occur over time. The aims of this study were to examine the patterns and prediction of behavior problems and the effects of gender and socioeconomic status (SES) on behavior problems in preterm children at the toddler and preschool periods.…

Introduction: The primary aim of this retrospective study was to assess differential associations between sleep disturbances with externalizing/internalizing problems, ADHD profiles (inattention, hyperactivity/impulsivity), and social impairment among children with ADHD, autism spectrum disorder (ASD), and comorbid diagnoses (ASD+ADHD). Methods:…

This study examined the prevalence of ADHD symptoms and anxiety as reported by parents and teachers for 180 preschool children (ages 4-5) and school-aged children (ages 6-7) with ASD using the Child Behavior Checklist--Parent and Teacher Report Forms (Achenbach and Rescorla, Manual for ASEBA school-age forms & profiles, Research Center for…

Disruptive mood dysregulation disorder (DMDD) is a controversial "DSM-5" diagnosis. It is not known how DMDD symptoms vary by age and if differences are similar for autism, ADHD, and general population samples. Our study analyzed the two DMDD symptoms (irritable-angry mood and temper outbursts) in 1,827 children with autism or ADHD (with…
