Adults with autism may overestimate the volatility of the world around them, finds a new UCL study published in Nature Neuroscience. The researchers found that adults with autism were less surprised by unexpected images in a simple learning task than adults without autism, and those who were the least surprised had the most pronounced symptoms. “We know from previous studies that people with autism often aren’t surprised by things that would surprise other people,” said lead author Dr Rebecca Lawson (UCL Wellcome Trust Centre for Neuroimaging). “Our results suggest that this may be because of differences in how people with autism build expectations. Our expectations bias our behaviour in subtle ways, so being less susceptible to these effects may result in strengths...
A new study out in European Journal of Neuroscience could herald a new tool that helps physicians identify a sub-group of people with Autism spectrum disorders (ASD). The test, which consists of measuring rapid eye movements, may indicate deficits in an area of the brain that plays an important role in emotional and social development. “These findings build upon a growing field of research that show that eye movement could serve as a window into a part of the brain that plays a role in a number of neurological and development disorders, such as Autism,” said John Foxe, Ph.D., director of the University of Rochester Medical Center Del Monte Neuroscience Institute and co-author of the study. ASD is characterized by a wide range of symptoms that can vary in severity from person to...
Oxytocin treatment has been proven efficient in improving the social behavior of some children with autism, studies have found. A new clinical trial investigates which children will respond best to this treatment and why. Autism is a developmental disability that often leads to struggles in communication, reduced empathy, and social inadaptability to a greater or lesser degree.
By analyzing the brains of mice, researchers have discovered how mutations in a gene called CHD8 may alter brain development and cognitive functioning to cause autism. Researchers from the United States and Canada found that CHD8 gene mutations altered gene expression in mice, impairing their cognitive functioning and increasing brain volume. Both of these characteristics are present in humans with autism who have CHD8 gene mutations.
Researchers are crowdsourcing mathematical whizzkids to help predict when a seizure might strike! When Dr Levin Kuhlmann (BSc(Hons) 2000) set about probing the mysteries of how and why epileptic seizures occur, he took a novel approach to advancing the cause. He organised an international crowdsourcing project. He and his Melbourne colleagues sought engineering talent rather than investors’ money, with the goal of writing computer algorithms capable of predicting epileptic seizures based on the electrical signals and activity recorded from patients’ brains.
Autism spectrum disorder affects 1 in 68 children in the U.S. Challenges with social skills, repetitive behaviors, speech and nonverbal communications are some of the issues people with autism may experience. But what many don’t know is that those with autism often struggle with an array of other health problems, too.
A recent study, published in Scientific Reports, concludes that if a girl’s maternal grandmother smoked tobacco during her pregnancy, she is significantly more likely to develop autistic traits. Could smoking increase the risk of your grandchildren displaying autism-associated traits? Autism, characterized by repetitive behaviors and difficulty interacting socially, appears to be on the rise. Much of this increase is thought to be due to better detection rates and greater awareness. However, many scientists believe that environmental or lifestyle factors might also play a role. A recent study, carried out by researchers from the University of Bristol in the United Kingdom, looked into three generations of data from the Avon Longitudinal Study of Parents and Children (ALSPAC), a long-...
Tiny, 3-D clusters of human brain cells grown in a petri dish are providing hints about the origins of disorders like autism and epilepsy. An experiment using these cell clusters — which are only about the size of the head of a pin — found that a genetic mutation associated with both autism and epilepsy kept developing cells from migrating normally from one cluster of brain cells to another, researchers report in the journal Nature.
isThe newest study from the Autism Speaks MSSNG project – the world’s largest autism genome sequencing program – identified an additional 18 gene variations that appear to increase the risk of autism. The new report appears in the journal Nature Neuroscience. It involved the analysis of 5,205 whole genomes from families affected by autism – making it the largest whole genome study of autism to date.
Research published this week in Biological Psychiatry examines levels of cerebrospinal fluid in children and its potential link to autism. If confirmed by further studies, it would become the first biomarker for the condition.
Children born to mothers who have active genital herpes during pregnancy may be at twice the risk of developing autism spectrum disorder, new research suggests. Researchers suggest a link between active HSV-2 in early pregnancy and autism risk in offspring. Lead author Milada Mahic, of the Center for Infection and Immunity and the Norwegian Institute of Public Health in Norway, and colleagues report their findings in the journal mSphere. Genital herpes is a common sexually transmitted infection primarily caused by herpes simplex virus 2 (HSV-2). Around 417 million people worldwide have genital herpes caused by HSV-2, with around 10-20 percent of cases occurring in people who have received a prior diagnosis of the condition.
Scanning a premature infant’s brain shortly after birth to map the location and volume of lesions, small areas of injury in the brain’s white matter, may help doctors better predict whether the baby will have disabilities later.
