Kennedy Krieger researchers uncover structural features of the brain that may contribute to disorder’s development

(Baltimore, MD) -- A study published today in AJP in Advance, the online advance edition of The American Journal of Psychiatry, the official journal of the American Psychiatric Association, reveals for the first time shape differences in the brains of children with ADHD, which could help pinpoint the specific neural circuits involved in the disorder. Researchers from the Kennedy Krieger Institute in Baltimore, Md.

Brain Imaging Study of Preschoolers with ADHD Detects Brain Differences Linked to Symptoms

Smaller brain volumes associated with severity of ADHD symptoms

(Baltimore, MD) – In a study published today in the Clinical Neuropsychologist (e-publication ahead of print), researchers from the Kennedy Kennedy Krieger Institute found differences in the brain development of preschool children with symptoms of Attention-deficit/Hyperactivity Disorder (ADHD). Results showed the region of the brain important for cognitive and motor control was smaller in these children than in typically developing children.

Study Using Simple "Go/No-Go" Task Finds Brain Inactivity Characterizes ADHD

Kennedy Krieger Research Update: Dr. Stewart Mostofsky

Dr. Stewart Mostofsky and his colleagues recently published a paper in the Journal of Cognitive Neuroscience examining differences in brain activity in children with Attention Deficit Hyperactivity Disorder (ADHD) and typically developing (TD) children. Dr. Mostofsky and his research team at the Kennedy Krieger Institute used a classic "Go/No-go" task to study response inhibition, or the ability to stop oneself from engaging in unwanted or unnecessary actions.

Study Finds ADHD Affects Motor Skills of Boys More Than Girls

Kennedy Krieger Institute researchers find girls with ADHD do not experience same motor skill difficulties as their male peers

(Baltimore, MD) - New research published in the November 4, 2008 issue of Neurology®, the medical journal of the American Academy of Neurology, found that ADHD affects the motor skills of boys more than girls. By examining age-related improvement of motor skills in children with and without ADHD, researchers from the Kennedy Krieger Institute in Baltimore, Md. found that girls with ADHD and their typically developing peers were more likely to be able to control their movements compared to boys with ADHD.

Kennedy Krieger Institute Awarded $9 Million To Study Learning Disabilities In Growing Ranks Of U.S. Adolescents

N.I.H. Grant Will Establish Center to Examine Causes of Reading Disorders, Including National "Fourth Grade Slump" In Which Successful Learners Suddenly Falter

(Baltimore, MD) - The substantial number of today's adolescents struggling with weak literacy skills presents an urgent national concern, yet very little is known about reading disabilities beyond the early elementary grades. To address this critical gap in knowledge, the Kennedy Krieger Institute has been awarded a $9 million grant from the National Institute of Health (N.I.H.) to establish a Learning Disabilities Research Center. The new center is among only four centers awarded in the country.

Research Identifies New Features Of Brain Structure That May Lead To ADHD

Research Conducted at the Kennedy Krieger Institute Takes New Approach to Studying Brain Basis of ADHD

(Baltimore, MD) - A study published today in Human Brain Mapping reveals an association between Attention Deficit Hyperactivity Disorder (ADHD) and a decrease in cortical volume, surface area and folding throughout the brain. Researchers from the Kennedy Krieger Institute in Baltimore, Md. found that children with ADHD showed decreased total brain volume and decreased volume throughout the cortex of the brain, the outer "grey matter" regions comprised of cells (neurons) of the brain.

Kennedy Krieger Researchers Exploring the Effects of ADHD on Girls

Condition likely nearly as prevalent in girls as boys; study aims to find better methods for diagnosis, treatment in girls

Baltimore- In the United States, an estimated five out of 100 school children have attention deficit hyperactivity disorder, which many experts believe is a neurobiological disorder that inhibits children - usually boys - from being able to control their behavior. A study at Kennedy Krieger Institute is now probing how ADHD uniquely affects girls - and experts hypothesize that it is probably much more common in girls than people think.

Study Shows Boys With ADHD Have Smaller Volume in Frontal Lobes of Brain

July 23, 2003
Abnormality likely related to key behavior problems associated with the disorder

Baltimore - Scientists at Kennedy Krieger Institute have confirmed that children with attention deficit hyperactivity disorder (ADHD) have smaller frontal lobes of the brain, a region that another Kennedy Krieger study has shown controls a key behavior, called "response inhibition," which generally is lacking in individuals with ADHD.
