Research by Autism Speaks-Funded Infant Brain Imaging Study Offers Future Promise to Identify Infants at Risk for Autism before Behavioral Symptoms Become Evident The changes in brain development that underlie autism spectrum disorder (ASD) may be detectable in children as young as 6 months, according to research reported online today in the American Journal of Psychiatry. While core behaviors associated with ASD (impaired social communication and repetitive behaviors) tend to be...

A new study combines genetic and neurobiological approaches to confirm that synaptic mutations increase the risk of autism spectrum disorders (ASDs) A new study combines genetic and neurobiological approaches to confirm that synaptic mutations increase the risk of autism spectrum disorders (ASDs). It also highlights a role for modifier genes in these disorders. Published in PLoS Genetics, this research was conducted by researchers at the Institut Pasteur, the Paris Diderot University, the...

Autism Chances Enhanced With Low Birth Weight

The basis of autism spectrum disorder (ASD) is long known to have a strong genetic component, however new research is suggesting that environmental factors may play an equally important role in this developmental disorder affecting nearly one in 100 children. The study, published in the journal Psychological Medicine suggests that low birth weight is an important environmental factor contributing to the risk of ASD, reports Wendy Leopold for Northwestern University. Lead author of the...

Neuroscientists have homed in on potential differences in the brain cells of autistic people by studying brainlike spheres grown in an elaborate process from skin cells. The scientists from Stanford University School of Medicine studied cells from patients suffering from Timothy syndrome, a rare genetic condition that is associated with one of the most penetrant forms of autism. Most people with the Timothy syndrome mutation have, among other health issues, autism as a symptom. Autism...

Although many mental illnesses are uniquely human, animals sometimes exhibit abnormal behaviors similar to those seen in humans with psychological disorders. Such behaviors are called endophenotypes. Now, researchers at the California Institute of Technology (Caltech) have found that mice lacking a gene that encodes a particular protein found in the synapses of the brain display a number of endophenotypes associated with schizophrenia and autism spectrum disorders. The new findings appear...

Findings show how brain's structure and genes affect autism and fragile X syndrome Research released today shows that scientists are finding new tools to help understand neurodevelopmental disorders like autism and fragile X syndrome. These studies show in new detail how the brain's connections, chemicals, and genes interact to affect behavior. The research findings were presented at Neuroscience 2011, the Society for Neuroscience's annual meeting and the world's largest source of emerging...

(Ivanhoe Newswire) -- The exact causes of autism remain unknown, but failure of a vital prenatal process may be one of the culprits. A new study, published in the November 9 issue of the Journal of the American Medical Society (JAMA), confirms this relatively recent theory. The study, by researchers at the University of California, San Diego Autism Center of Excellence, shows that brain overgrowth in boys with autism involves excess neurons in areas of the brain associated with social,...

Analysis reveals overlap between genetic and epigenetic risk maps of autism Scientists at the University of Massachusetts Medical School are the first to map epigenetic changes in neurons from the brains of individuals with autism, providing empirical evidence that epigenetic alterations–changes in gene expression caused by mechanisms other than changes in the underlying DNA sequence–may play an important role in the disease. Analysis of these variations revealed hundreds of...

Neurons in the prefrontal cortex of individuals with autism show changes at numerous sites across the genome, according to a study being published Online First by the Archives of General Psychiatry, one of the JAMA/Archives journals. Autism spectrum disorders are a group of complex illnesses with different causes and origins. Neuronal dysfunction in the cerebral cortex and other regions of the brain could contribute to the cognitive and behavioral defects in autism, according to background...

Autism Spectrum Disorder (ASD) affects about 1 in 100 children resulting in a range of problems in language, communication and understanding other people's emotional cues, all of which can lead to difficulties in social situations. Boys are three to four more times as likely to be affected as girls and consequently it has been suggested that the genes involved in this disorder may be linked to the X chromosome. New research published in BioMed Central's open access journal Molecular Autism...
