Topic: Study of Differences in Autism Symptoms Between Minority and Caucasian Toddlers

Dr. Rebecca LandaKennedy Krieger Institute researchers have published the first study of ethnic differences in the presentation of early symptoms of autism in toddlers, and the results show that children from a minority background have more delayed language, communication and gross motor skills than Caucasian children with the disorder.

Kennedy Krieger researchers find that varying practice sessions may benefit people with motor disorders

(Baltimore, MD) -- Learning from one's mistakes may be better than practicing to perfection, according to a new study appearing in the October 19 issue of The Journal of Neuroscience. Researchers from the Kennedy Krieger Institute found that forcing people to switch from a normal walking pattern to an unusual one -- and back again -- made them better able to adjust to the unusual pattern the following day. The findings may help improve therapy for people relearning how to walk following stroke or other injury.

Kennedy Krieger researcher finds unexpected familial relationships in data widely used by biomedical research community

(Baltimore, MD) -- At a time when profound gaps remain in our understanding of how one person’s genes differ from another person’s , developing accurate methods to interpret the human genome is essential to uncover population history, population relationships and the genetic basis of some of the most common diseases affecting society.

Interactive Autism Network asks families to report on bullying experiences of children with ASD

(Baltimore, MD) -- Today, the Interactive Autism Network (IAN Project) launches a national survey to study the impact of bullying on children with autism spectrum disorders (ASD). Bullying, a pervasive problem among youth, has attracted the national spotlight in recent months because of the lasting, and sometimes tragic, effects on children and teenagers across the country.

Study shows DSM criteria can be used to identify autism in children with Down syndrome.

October 4, 2011 (Baltimore, MD) -- New findings from a 16-year study confirm that the Diagnostic and Statistic Manual of Mental Disorders (DSM), the gold-standard for the classification of mental health conditions, can be used to accurately identify autism spectrum disorders (ASD) in children with Down syndrome, according to research from Kennedy Krieger Institute.

Study Reveals Link Between Early Number Sense and Elementary Math Scores

September 14, 2011 (Baltimore, MD) -- A new study published today in the journal PLoS ONE reports that the precision with which preschoolers estimate quantities, prior to any formal education in mathematics, predicts their mathematics ability in elementary school, according to research from the Kennedy Krieger Institute.

Study Indicates Infants at Risk for Autism Could Benefit from Motor Training

September 9, 2011 (Baltimore, MD) -- In a new study published today in the journal Developmental Science (Epub ahead of print), researchers from the Kennedy Krieger Institute and Vanderbilt University found that early motor experiences can shape infants' preferences for objects and faces.

Study highlights importance of routine surveillance, rapid referral for infant siblings of children with ASD

August 15, 2011 (Baltimore, MD)—A new study published today in the journal Pediatrics (Epub ahead of print) found that the risk that an infant sibling of an older child with an autism spectrum disorder (ASD) will also develop the condition, known as recurrence risk, is substantially higher than previously thought. The study found that the average risk of recurrence is 18.7 percent, much higher than the previous estimates of 3 to 10 percent.

Poor "Gut Sense" of Numbers Contributes to Persistent Math Difficulties

Study Reveals Math Learning Disabilities Are Caused By Multiple Factors, Including Poor Intuition in Gauging Numerical Quantities

(Baltimore, MD) – A new study published today in the journal Child Development (e-publication ahead of print) finds that having a poor “gut sense” of numbers can lead to a mathematical learning disability and difficulty in achieving basic math proficiency. This inaccurate number sense is just one cause of math learning disabilities, according to the research led byDr. Michele Mazzocco of the Kennedy Krieger Institute.

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

June 9, 2011
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.
