Science News About Autism

NIMH, along with NICHD, NINDS, NIDCD, and NIEHS, have awarded nine new grants aimed at advancing research on the causes of autism spectrum disorder and finding new treatments.

Data from a nationally representative survey show that teens with autism appear to face additional challenges after graduating high school than peers with similar disabilities. NIMH-funded researchers highlight the need to improve transition planning and for further studies on the effectiveness of services for adults with autism.

Brain areas involved in social behavior are active but out of sync with each other in young people with autism, according to recent findings from functional brain imaging.

New data detail the experiences of young children with autism spectrum disorder, describing when they are first identified as having ASD, who is making those identifications, and the services and medications the children use to meet their developmental needs.

Autism-like behaviors in mice have been reduced, using an experimental agent being tested in patients for a related disorder.

A trio of new studies have found that sequence changes in parts of genes that code for proteins play a significant role in autism spectrum disorders (ASDs).

For the first time, scientists have tracked the activity, across the lifespan, of an environmentally responsive regulatory mechanism that turns genes on and off in the brain’s executive hub. Among key findings of the study by National Institutes of Health scientists: genes implicated in schizophrenia and autism turn out to be members of a select club of genes in which regulatory activity peaks during an environmentally-sensitive critical period in development.

A data partnership between the National Database for Autism Research (NDAR), and the Autism Genetic Resource Exchange (AGRE) positions NDAR as possibly the largest repository to date of genetic, phenotypic, clinical, and medical imaging data related to research on autism spectrum disorders (ASD).

Children with autism spectrum disorder (ASD) who attend regular education classes may be more likely to improve their social skills if their typically developing peers are taught how to interact with them than if only the children with ASD are taught such skills. According to a study funded by the National Institutes of Health, a shift away from more commonly used interventions that focus on training children with ASD directly may provide greater social benefits for children with ASD.

Potential clues to how autism miswires the brain are emerging from a study of a rare, purely genetic form of the disorders that affects fewer than 20 people worldwide. Using cutting-edge “disease-in a-dish” technology, researchers funded by the National Institutes of Health have grown patients’ skin cells into neurons to discover what goes wrong in the brain in Timothy Syndrome. Affected children often show symptoms of autism spectrum disorders along with a constellation of physical problems.

Children with autism have more brain cells and heavier brains compared to typically developing children, according to researchers partly funded by the National Institutes of Health.

Rats exposed to an antidepressant just before and after birth showed substantial brain abnormalities and behaviors, in a study funded by the National Institutes of Health.

Parents of a child with autism spectrum disorder (ASD) face about a 19 percent chance that subsequent children will also develop ASD, according to a study partially funded by NIMH.

The largest and most rigorous twin study of its kind to date has found that shared environment influences susceptibility to autism more than previously thought.

Autism blurs the molecular differences that normally distinguish different brain regions, a new study suggests. Among more than 500 genes that are normally expressed at significantly different levels in the front versus the lower middle part of the brain’s outer mantle, or cortex, only 8 showed such differences in brains of people with autism, say researchers funded in part by the National Institutes of Health.

The prevalence of autism spectrum disorder (ASD) among children in South Korea appears to be much higher than the range of estimates reported for other countries, according to a study partly funded by NIMH. Furthermore, two-thirds of ASD cases were found in children attending mainstream schools, had not been previously diagnosed, and had never received treatment for the disorder. The study was published on May 9, 2011, in the American Journal of Psychiatry.

A five-minute checklist that parents can fill out in pediatrician waiting rooms may someday help in the early diagnosis of autism spectrum disorder (ASD), according to a study funded by the National Institutes of Health. Published today in the Journal of Pediatrics, the study’s design also provides a model for developing a network of pediatricians to adopt such a change to their practice.

Mice bred to harbor mutations similar to those discovered in people with autism show autism-like repetitive behaviors and social impairments. The behaviors, triggered by deletions in a gene called SHANK3, implicated in some cases of autism, were traced to weak neural connections for functions disturbed in autism.

JobTIPS, a free, Web-based program unveiled today, aims to help youth with autism spectrum disorder (ASD) or other disabilities develop and maintain skills needed for successful employment. Supported through the Recovery Act with a grant for just under $1 million over two years from the National Institutes of Health, this resource targets a critical transition period as teenagers leave the school system, which is usually their primary source of ASD-related services throughout childhood.

NIMH will be supporting a joint effort with the Centers for Disease Control and Prevention (CDC) and Autism Speaks, a private advocacy organization, to investigate reports of elevated prevalence of autism spectrum disorders (ASD) among children born to Somali immigrants living in Minneapolis, Minn.

Targeting the core social deficits of autism spectrum disorders (ASD) in early intervention programs yielded sustained improvements in social and communication skills even in very young children who have ASD, according to a study funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health. The study was published online July 28, 2010, in the Journal of Child Psychology and Psychiatry.

A 1-minute video showing computer screensavers next to videos of dancing children may prove to be a simple, inexpensive screening tool for autism spectrum disorders (ASD) in toddlers. According to an NIMH-funded study, infants as young as 14 months old who had autism spent more time looking at the moving shapes than social images, in contrast to typically developing children and those who had delays but not autism. The study was published online, September 6, 2010, in the Archives of General Psychiatry.

Differences in brain growth patterns between preschool-aged boys with Fragile X syndrome (FXS), the most common cause of inherited intellectual disability, and their healthy peers suggest that the disorder may affect brain development both before and after birth, according to NIMH-funded researchers. In addition, their findings indicate ages 1–5 are an important window for better understanding the effects of FXS on brain development. The study was published May 18, 2010, in the Proceedings of the National Academy of Sciences.

Researchers studying autism spectrum disorders (ASD) will soon have access to a vast range of data and research tools through the NIH National Database for Autism Research (NDAR).

Children with autism who receive a high intensity developmental behavioral intervention starting by age 18–30 months show major improvements in IQ, language, adaptive behavior, and severity of their diagnosis, according to an NIMH-funded study.

For the first time, inherited disruption of gene expression in a brain system for social behavior has been implicated in autism. NIMH grantee Margaret Pericak-Vance, Ph.D., at the University of Miami and Simon Gregory, Ph.D., at Duke University, and a multinational team of researchers found evidence for such epigenetic effects on the gene for the oxytocin receptor -- part of a brain system that mediates social behaviors disturbed in autism. The findings suggest a potential genetic biomarker for the disorder.

Treatment that includes medication plus a structured training program for parents reduces serious behavioral problems in children with autism and related conditions, according to a study funded by the National Institute of Mental Health (NIMH). The study, which was part of the NIMH Research Units on Pediatric Psychopharmacology (RUPP) Autism Network, was published in the December 2009 issue of the Journal of the American Academy of Child and Adolescent Psychiatry.

Most children with autism spectrum disorders (ASD) seem to have trouble engaging in everyday social interactions. They may seem to have no reaction to other people or may respond atypically when others show anger or affection. Their own facial expressions, tone of voice, and body language may not match what they are saying, making it difficult for others to respond appropriately. Such barriers to communication can isolate children with ASD from their peers.

The National Institutes of Health (NIH) awarded more than 50 autism research grants, totaling more than $65 million, which will be supported with American Recovery and Reinvestment Act (Recovery Act) funds. These grants are the result of the largest funding opportunity for research on autism spectrum disorders (ASD) to date, announced in March 2009.

A landmark, multisite NIH-funded neuroimaging study of brain development in healthy, normally-developing children has posted its third release of data. This is the first release from the magnetic resonance imaging (MRI) study to include data from very young children – birth to 4 years old – and snapshots of brain chemistry at key developmental milestones. The data is accessible to qualified researchers via the NIH Pediatric MRI Data Repository website.

NIH-supported scientists at Seaside Therapeutics in Cambridge, Mass., are beginning a clinical trial of a potential medication designed to correct a central neurochemical defect underlying Fragile X syndrome, the most common inherited cause of intellectual disability. There has to date been no medication that could alter the disorder’s neurologic abnormalities. The study will evaluate safety, tolerability, and optimal dosage in healthy volunteers.

The transition from teen to young adult involves many highly anticipated rites of passage. However, for youths with developmental disorders, coming of age may signal the sudden end of coverage for education and training programs, health insurance, and youth-oriented services.

Citalopram, a medication commonly prescribed to children with autism spectrum disorders (ASD), was no more effective than a placebo at reducing repetitive behaviors, according to researchers funded by the National Institute of Mental Health (NIMH) and other NIH institutes. The study was published in the June 2009 issue of Archives of General Psychiatry.

Individuals with autism spectrum disorders (ASD) tend to stare at people’s mouths rather than their eyes. Now, an NIH-funded study in 2-year-olds with the social deficit disorder suggests why they might find mouths so attractive: lip-syncing — the exact match of lip motion and speech sound.

The National Institutes of Health (NIH) will commit roughly $60 million from American Recovery and Reinvestment Act (ARRA) to support autism research and meet objectives set forth earlier this year by a federal advisory committee. The Request for Applications is the largest funding opportunity for research on autism spectrum disorders (ASD) to date and combined with other ARRA initiatives represents a surge in NIH’s commitment to finding the causes and treatments for autism.

A new NIMH-funded study will help guide the treatment of attention deficit hyperactivity disorder (ADHD) symptoms in children with autism spectrum disorders (ASD).

People with schizophrenia from families with no history of the illness were found to harbor eight times more spontaneous mutations – most in pathways affecting brain development – than healthy controls, in a study supported in part the National Institutes of Health’s (NIH) National Institute of Mental Health (NIMH). By contrast, no spontaneous mutations were found in people with schizophrenia who had family histories of the illness.

Reviews of the current research on psychosocial and behavioral therapies, or psychotherapies, for children and adolescents found a number of well established and probably efficacious treatments for many mental disorders. For example, six were probably efficacious for anxiety disorders, and two were well established for attention deficit hyperactivity disorder (ADHD), according to scientists funded by NIMH and the National Institute on Drug Abuse, divisions of the National Institutes of Health.

The National Institutes of Health (NIH) announced on April 1, 2008, the latest recipients of the Autism Centers of Excellence (ACE) program.

Four teams of scientists, using resources supported in part by NIMH, have pinpointed two different sites in the genome, each conferring a different type of genetic risk for autism. At one site, risk genes appear to be inherited. At the other, risk stems from spontaneous mutations, not seen in the genetics of the parents. In both examples, evidence suggests the suspect genes are critical for development of brain circuits impaired in autism.

Scientists have found a variation in a gene that may raise the risk of developing autism, especially when the variant is inherited from mothers rather than fathers. The research was funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health.

A new NIMH grant is enabling scientists to begin testing safety and effectiveness of potential medications for fragile-X syndrome, the most common inherited form of mental retardation. No effective medications are available for the disorder.

How genes and the environment shape the brain circuitry underlying social behavior is among the questions being addressed by three newly NIMH-funded studies.

NIMH is funding several new grants that will further our understanding of autism spectrum disorder, which is marked by a pervasive impairment in communicating, expressing emotion, and relating to others socially.

About half of children with autism spectrum disorders (ASD) can be diagnosed soon after their first birthday; others with the disorder may appear to develop normally until that age and then falter or regress during their second year, NIMH-funded researchers have discovered.

Tiny gene mutations, each individually rare, pose more risk for autism than had been previously thought, suggests a study funded in part by the National Institute of Mental Health, a component of the National Institutes of Health.

The largest search for autism genes to date, funded in part by the National Institutes of Health (NIH), has implicated components of the brain’s glutamate chemical messenger system and a previously overlooked site on chromosome 11.
