Researchers have identified changes in brain connectivity and brain activity during rest and reward anticipation in children with anhedonia, a condition where people lose interest and pleasure in activities they used to enjoy. The study sheds light on brain function associated with anhedonia and helps differentiate anhedonia from other related aspects of psychopathology.
Currently approved in Canada and Europe for adults with medication-resistant depression and seizures, trigeminal nerve stimulation (TNS) has been found to be an effective and safe means of treatment for children with attention deficit hyperactivity disorder (ADHD), reports a new study.
One in three students with ADHD received no school-based interventions and two of three received no classroom management, researchers found in the largest study of children and teens with ADHD ever conducted. At least one in five students with ADHD who experience significant academic and social impairment - those most in need of services - received no school intervention. The gap was particularly evident for adolescents and youth from non-English-speaking and/or lower income families.
A pair of new studies has provided new insight into the challenges faced by children on the autism spectrum who exhibit symptoms of attention deficit/hyperactivity disorder (ADHD). According to the findings, these children have difficulty with adaptive behavior, a key measure of independence.
A new study in children aged 6 to 12 years of dasotraline, a promising new treatment for attention deficit hyperactivity disorder (ADHD), showed significant improvement in efficacy in the treatment of ADHD compared to placebo beginning at week 1 and continuing throughout the study.
There is only scant scientific evidence on whether the genetic risk for developing specific psychiatric disorders or cognitive traits is manifest in brain structure from childhood and, to date, studies have focused primarily on adult populations. The question remains unanswered.
A study finds a surprising response to cocaine in a novel strain of mutant mice -- they failed to show hyperactivity seen in normal mice when given cocaine and didn't run around. In other tests, they still found cocaine appealing, but displayed an inability to shake the memory of cocaine's actions when the drug was no longer administered. The key change that blocks cocaine's stimulant effects in these mice is serotonin, not dopamine, which is responsible for producing a high.
Researchers evaluated a digital medicine tool designed as an investigational treatment for children with autism spectrum disorder (ASD) and co-occurring attention/deficit-hyperactivity disorder (ADHD).
African-American children often are reported by parents and teachers to display behaviors of ADHD at a higher rate than children from other racial and ethnic groups. For the first time, researchers have found that African-American mothers in a study rated boys as displaying more frequent ADHD symptoms than Caucasian mothers did, regardless of child race.
Children who enter elementary school younger than their peers are more likely to be diagnosed with ADHD. Children born in August in states with a Sept. 1 cutoff birth date for school enrollment have a 30 percent higher risk for ADHD diagnosis than peers born in September, which may reflect over-diagnosis.
An international study, focused on the analysis of the genome of more than 50,000 people worldwide, has identified twelve specific fragments of DNA related to the vulnerability of the attention deficit hyperactivity disorder (ADHD).
A father's exposure to nicotine may cause cognitive deficits in his children and even grandchildren, according to a new study. The effect, which was not caused by direct secondhand exposure, may be due to epigenetic changes in key genes in the father's sperm.
In an investigation of head impact burden and change in neurocognitive function during a season of youth football, researchers find that sub-concussive impacts are not correlated with worsening performance in neurocognitive function.
People often believe those with Attention Deficit Hyperactivity Disorder face challenges that could hinder future employment, but a new study found that adults with ADHD feel empowered doing creative tasks that could help them on the job.
Scientists using machine learning -- a type of artificial intelligence -- with data from hundreds of children who struggle at school, identified clusters of learning difficulties which did not match the previous diagnosis the children had been given. The researchers from the Medical Research Council Cognition and Brain Sciences Unit at the University of Cambridge say this reinforces the need for children to receive detailed assessments of their cognitive skills to identify the best type of support.
In both ADHD and emotional instability disorders (e.g. borderline and antisocial personality disorder as well as conduct disorder in children), the brain exhibits similar changes in overlapping areas, meaning that the two types of conditions should be seen as related and attention should be paid to both during diagnosis.
