Leonardo da Vinci produced some of the world's most iconic art, but historical accounts show that he struggled to complete his works. New research now suggests the best explanation for Leonardo's inability to finish projects is that the great artist may have had attention deficit and hyperactivity disorder (ADHD).
Results of a new study reports that parental age is linked to the risk for the development of neuropsychiatric disorders in children, including autism spectrum disorder (ASD); attention-deficit/hyperactivity disorder (ADHD); obsessive-compulsive disorder (OCD); and Tourette's disorder/chronic tic disorder (TD/CT).
Teen drivers diagnosed with attention-deficit hyperactivity disorder (ADHD) are significantly more likely to crash, be issued traffic and moving violations, and engage in risky driving behaviors than their peers without ADHD.
Behavioral problems in young people with severe antisocial behavior -- known as conduct disorder -- could be caused by differences in the brain's wiring that link the brain's emotional centers together, according to new research.
New research in rodents reveals for the first time how dopamine changes the function of the brain's prefrontal cortex. Researchers found that dopamine has little effect on individual cells. Instead, it generates sustained activity in the ensemble of cells in the prefrontal cortex that lasts for up to 20 minutes.
A study suggest that the risk of a child developing symptoms of attention deficit hyperactivity disorder (ADHD) may be modulated by the mother's diet during pregnancy. The research analyzed samples of umbilical cord plasma to quantify the levels of omega-6 and omega-3 that reach the fetus. The analysis showed a higher omega-6:omega-3 ratio to be associated with a higher risk of ADHD symptoms at seven years of age.
A new, 12-year longitudinal study, which monitored 6,830 children from early childhood into adolescence, has shown that consistent treatment with MPH-based medications during childhood increases the risk of antidepressant use during adolescence. The study is the first of its kind to examine the connection between children diagnosed with ADHD and prescribed MPH between the ages of six and eight, and future dispensed prescriptions of antidepressants.
Researchers evaluated the two most common ADHD treatments and found that, although the risk of psychosis is low, it is greater for patients who are taking amphetamines than for those taking methylphenidates.
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.
