New ADHD Gene Study Points to Defects in Brain Signaling Pathways

New ADHD Gene Study Points to Defects in Brain Signaling Pathways"Pediatric researchers analyzing genetic influences in attention-deficit/hyperactivity disorder (ADHD) have found alterations in specific genes involved in important brain signaling pathways. The study raises the possibility that drugs acting on those pathways might offer a new treatment option for patients with ADHD who have those gene variants—potentially, half a million U.S. children."

Music can improve concentration in some children with ADHD

Music can improve concentration in some children with ADHDThis article describes a study which found that for many children playing music in the background can actually improve concentration. This is something that many of the people I work with have described as well so it's good to see some research supporting this. It does vary from person to person though. On the other hand, having TV on in the background is actually a significant distraction.

Scientists reveal how psychostimulant drugs work to control hyperactivity

Scientists reveal how psychostimulant drugs work to control hyperactivityPublished on February 8, 2012This article describes a 2012 study which has shed light on why stimulant medication paradoxically reduces motor activity.  Stimulant medications work by increasing levels of dopamine in the brain.  The researchers found that stimulating dopamine D4 receptors in the basal ganglia and thalamus (structures deep in the brain) decrease motor activity, explaining how the stimulant can have a calming effect.
