New evidence suggests that autism begins in the brain before birth when brain cells fail to develop properly. In this study, the abnormalities in the brain cells were not uniform, showing autism's wide range of symptoms and severity. This better understanding of prenatal development of the brain cells of people with autism underscores the importance of early identification and intervention.
Researchers have developed a method to isolate a single mutant cell from thousands of others, they reported in the March issue of Nature Methods. The new approach will allow researchers to precisely engineer and study human cells without altering the genome. Ultimately, the method could be used to alter an individual’s cells before returning them to his or her body.
The Autism Science Foundation invites applications from highly qualified undergraduates interested in pursuing basic and clinical research relevant to autism spectrum disorders during the summer.
The proposed research must be scientifically linked to autism or a closely related field. Autism Science Foundation will consider all areas of related basic and clinical research including but not limited to: human behavior across the lifespan (language, learning, communication, social function, epilepsy, sleep, self-injurious behavior, catatonia), neurobiology (anatomy, development, neuro-imaging), pharmacology, neuropathology, human genetics, genomics, epigenetics, epigenomics, immunology, molecular and cellular mechanisms, studies employing model organisms and systems, and studies of treatment and service delivery.
Autism is defined based on a wide variety of behavioral symptoms, but it's precisely this variation — along with a complex genetic background — that makes it tricky to connect behavior to the underlying genes. A new algorithm may make this challenge a bit easier to solve. The algorithm, which employs a form of artificial intelligence that learns as it goes, analyzes behavioral data and has learned to recognize six genetic disorders associated with autism, according to research published in Molecular Autism. The researchers hope to use these behavioral signatures to hone their search for the genetic underpinnings of ‘idiopathic autism,’ for which there is no known cause.
The risk of certain autism spectrum disorders is highest in firstborn children and declines in each additional sibling born to the same mother, reports a large Finnish study published in Paediatric and Perinatal Epidemiology. When the researchers looked at Asperger syndrome, pervasive developmental disorder–not otherwise specified (PDD-NOS) and childhood autism, in which symptoms appear before the age of 3, as a group, they found that a diagnosis is most common in firstborns. The latter two conditions are now considered part of the autism diagnosis. When they looked at each diagnosis separately, the researchers found that the firstborn effect holds for Asperger and PDD-NOS, while second-born children are at the highest risk for childhood autism.
Scoring Goals for Autism is an annual soccer tournament fundraiser that benefits the Autism Science Foundation. Scoring Goals for Autism will take place at YSC Sports in Wayne, PA on Sunday, April 27, 2014. This one-of-a-kind indoor soccer tournament offers both competitive team play for adult players as well a TOPSoccer skills and drills clinic for children and adolescents with special needs including autism.
The mission of Scoring Goals for Autism is to bring the beautiful game of soccer to all athletes and to raise much needed dollars for autism research. All proceeds from Scoring Goals for Autism benefit the Autism Science Foundation.
Autism researchers and advocates often express concern that the average age of autism diagnosis in the U.S. hovers around 4 years even though most cases of the disorder can be reliably identified by age 2. In this highly contentious field, the need for early diagnosis and early intervention is one of the few areas of agreement. Surprisingly, though, there has been little hard evidence that earlier diagnosis improves the lives of people with autism in the long term. At last, this evidence is becoming available. The field turned toward more rigorous studies a decade or so ago, and many of those studies, focused on children between about 2 and 4 years old, are starting to bear fruit.
Researchers have more clues as to why more boys than girls are diagnosed with Autism Spectrum Disorder. A new study in the American Journal of Human Genetics suggests that for boys, it takes less of a genetic hit to cause autism than it does for girls. The study continues to say that when it does appear in girls, it is due to a much more severe genetic hit, usually resulting in much more severe autism symptoms.
Even at rest, the brains of people with autism manage more information than those of their peers, according to a new study that may provide support for the so-called ‘intense world’ theory of autism. The research, which was published in Frontiers in Neuroinformatics, included nine children with Asperger syndrome, aged between 6 and 14 and ten age-matched typical children. The researchers scanned their brains using magnetoencephalography (MEG), a noninvasive method that doesn’t require lying in a noisy, confined space as magnetic resonance imaging does. The results suggest that in the same boring situation, people with autism process more information than their typical peers.
A rigorous new study confirms that boys with autism tend to score higher on tests of spatial and analytical abilities than on those for verbal skills. But the gap decreases by the time they reach 10 years of age. This suggests that the trait cannot be used to define children with autism or their families, the researchers say. Instead, it may be a pattern of development common in children with autism or other developmental disorders. The report was published in the January issue of the American Journal on Intellectual and Developmental Disabilities.
