Latest Causes of autism Stories
NAA Calls NIH Autism Gene Search a Waste of Money, Says Focus Should be on Environmental Causation NIXA, Mo., July 8, 2011 /PRNewswire-USNewswire/ -- A study published this week again confirms that environmental factors play a critical role in the development of autism.
The largest known study of twins with autism spectrum disorder (ASD) suggests that environmental influences and maternal infections during pregnancy may greatly increase risk for ASD.
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 Speaks, the world's largest autism science and advocacy organization, joined in announcing significant findings from the largest known study of twins with autism spectrum disorder (ASD).
After evaluating twin pairs in which at least one child has autism or autism spectrum disorder (ASD), researchers suggest that the shared environment may play a more substantial role in development of the condition than shared genes do.
In a novel imaging study of sleeping toddlers, scientists at the University of California, San Diego Autism Center of Excellence report that a diminished ability of a young brain's hemispheres to "sync" with one another could be a powerful, new biological marker of autism, one that might enable an autism diagnosis at a very young age.
Autism is often described as a spectrum â€“ varying from severe syndromes in which the symptoms of autism are only part of the problem to the more classic autism characterized by impaired social skills, delayed language development, and repetitive or stereotyped behaviors.
Many roads can lead to the same place, often crossing over one another and sometimes passing the same landmarks.
For decades, autism researchers have faced a baffling riddle: how to unravel a disorder that leaves no known physical trace as it develops in the brain.
A gene-sequencing study of children with autism, described in an advance online publication in Nature Genetics on 15 May, offers a sneak peek at a technique which, combined with other approaches, may explain 40 to 50 percent of the genetic causes of the disorder within just a few years, proposes the study's lead investigator.

- The protecting weather-shed built around the entrance to a house.
- The roofed-over space between the kitchen and the sleeping-quarters in a logging-camp, commonly used as a storeroom.
