The study highlights the importance of identifying and treating ADHD symptoms in individuals with autism.
A study of over 400 children with ADHD found a link between regular outdoor play in green settings and milder symptoms. Children who regularly played outdoors had better impulse control and concentration than those who played indoors or in built-outdoor environments.
A study published in the Journal of Neuroscience found that differences in when movement neurons begin accumulating information from sensory neurons explain adjustments in response times. This discovery forces a major modification to existing cognitive models of impulse control, shedding new light on how the brain controls basic impulses.
A study using mice reveals how a specific gene variant could contribute to attention-deficit hyperactivity disorder (ADHD). The researchers found that the D4.7 variant of the dopamine D4 receptor subtype was not able to interact with another brain region in a way that reduces glutamate release, leading to symptoms of ADHD.
Scientists discovered that the intestinal membrane receptor protein, GC-C, is also expressed in critical brain areas. The study found that GC-C's activation amplifies dopamine responses, leading to hyperactivity and attention deficits in mice. Treatment with a PKG activator reversed these behavioral problems.

The researchers analyzed the data from twins to determine the similarities in genetic and environmental influence between ADHD symptoms and academic ability.
Children with DCD tend to struggle with motor skills, socialization, and emotional regulation, leading to feelings of loneliness and isolation. The study found that voluntary lack of participation in after-school activities can exacerbate the problem, but intervention is possible with proper diagnosis and monitoring.
Children with heavy prenatal alcohol exposure (PAE) and ADHD exhibit different patterns of learning and memory impairments. PAE is associated with initial encoding problems, while ADHD affects retrieval mechanisms, suggesting distinct underlying deficits.
