For decades, neuropsychologists have used the Wechsler Intelligence Scale for Children test as the gold-standard intelligence quotient (IQ) test to determine the intellectual abilities of children with special needs. However, this comprehensive test can take up to 2 hours to complete, and many children with special needs have a difficult time participating in such long tests.
The frequency of genetic variants associated with attention-deficit/hyperactivity disorder (ADHD) has decreased progressively in the evolutionary human lineage from the Paleolithic to the present day, according to new research.
Different learning difficulties do not correspond to specific regions of the brain, as previously thought, say researchers. Instead poor connectivity between 'hubs' within the brain is much more strongly related to children's difficulties.
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 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.
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.
