The risk of ADHD was 34 percent higher in children whose mother had a vitamin D deficiency during pregnancy than in those children whose mother's vitamin D level was sufficient during the first and second trimesters. The result was adjusted for maternal age, socioeconomic status and psychiatric history.
Researchers have identified how certain areas of the human brain respond to methylphenidate -- a stimulant drug which is used to treat symptoms of ADHD. The work may help researchers understand the precise mechanism of the drug and ultimately develop more targeted medicines for the condition.
Researchers have shown that the brains of young adult Romanian adoptees who were institutionalized as children are around 8.6% smaller than the brains of English adoptees who have not suffered this form of deprivation.
Deep learning, a type of artificial intelligence, can boost the power of MRI in predicting attention deficit hyperactivity disorder (ADHD), according to a new study. Researchers said the approach could also have applications for other neurological conditions.
Researchers have found that autism and ADHD share changes in the same genes. The new knowledge relates directly to the biological causes of the two child psychiatric disorders.
Researchers have investigated the actions of the drug in rats. Using dopamine cell recordings, electrochemical monitoring and computer modeling, they discovered a type of feedback loop that modulates dopamine levels in the rats' brains in response to the drug. This regulatory process may shed light on methylphenidate's therapeutic properties in ADHD.
Young mothers have a greater chance of having a child with attention deficit hyperactivity disorder (ADHD), according to new research. Exploring the genetic relationship between female reproductive traits and key psychiatric disorders, it found that the genetic risk of ADHD in children was strongly associated with early maternal age at first birth, particular for women younger than 20.
A new study has shown that an interactive avatar, which gives both instructions and feedback on the attention of the learner, can improve the performance of ADHD children on a complex problem-solving task.
A large study has shown that children of mothers who are anxious during pregnancy and in the first few years of the child's life have twice the risk of having hyperactivity symptoms at age 16.
Researchers have found that as premature babies grow, their mental health may be related less to the medical challenges they face after birth than to the environment the babies enter once they leave the neonatal intensive care unit.
A de novo gene mutation that encodes a brain protein in a child with autism has been placed into the brains of mice. These mice then showed severe alterations of specific behaviors that closely resemble those seen in human autism spectrum disorder, or ASD.
Preschoolers with symptoms of attention-deficit hyperactivity disorder are much less likely than other children their age to be ready for school, new research has found.
Researchers examined the impact of preterm birth on language outcomes in preschoolers born preterm and full-term, using both standardized assessment and language sample analysis. They also explored semantic skills and grammatical ability, and nonlinguistic developmental skills of nonverbal intelligence, attention, and hyperactivity. Results show that language difficulties at the discourse level may still exist even when children who are born preterm appear to be developing typically when they are evaluated by standardized assessments of global language ability, cognition, and attention.
A new study reviewed evidence from research conducted around the world and estimated the prevalence of conduct disorder to be around 3 percent in school-aged children and a leading cause of referral to child and adolescent mental health services. Yet paradoxically it is one of the least widely recognized or studied psychiatric disorders, and funding for research into it lags far behind many other childhood disorders.
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.
