Autism Detectable In Infants, Study Suggests


MRI study: Autism Detectable at 6 months of Age
 By using a technique known as machine learning to look at brain patterns in infants, researchers say they were able to successfully flag most children on the spectrum well before symptoms appeared.
The findings published in the journal Science Translational Medicine may offer a first step to developing an early detection method for autism, researchers said.
 For the study, 59 sleeping babies spent 15 minutes each in an MRI machine so brain activity in 230 neural regions could be observed. Researchers then analyzed how different regions worked with each other, using a machine learning classifier — essentially a computer program — to distinguish patterns. All of the children studied were considered to be at high risk for autism because they had an older sibling with the disorder. Ultimately, 11 of the babies were diagnosed with autism at age 2, nine of whom were identified by the machine learning classifier as babies.
“When the classifier determined a child had autism, it was always right. But it missed two children. They developed autism but the computer program did not predict it correctly, according to the data we obtained at 6 months of age,” said Robert Emerson, who led the study as a postdoctoral fellow at the University of North Carolina.

Study Finds Medicaid Waivers Help Parents Stay Employed

Image
Parents of children with autism are more likely to remain in the workforce if they have access to Medicaid waiver services for their kids, new research suggests. In a study looking at over 17,000 children on the spectrum, researchers found a link between the availability of waivers and parent employment. Read more........

News on Human Behavior: Brain Scans Could Help Doctors Better Predict Your Behavior

Image
 (CNN REPORT):  Forget horoscopes or fortune tellers. There's a new way to tell your future, and it involves a much more reliable medium: human neuroscience. A new study looks at over 70 scientific publications about brain scans such as functional magnetic resonance imaging or electroencephalography, noninvasive tests that measure brain activity. The paper that runs in the latest edition of Neuron concludes that doctors might have more success treating some patients if they examined the way a person's brain functioned first. Brain scans have been used to make basic discoveries about human behavior for decades, but they are not routinely ordered to determine someone's overall health or course of treatment in the way as blood test are used. This new study suggests technology in this area has become so advanced that approaches to treatment would be more effective if brain scans were used more routinely. For instance, when someone is being treated f

After Ethan Saylor Death in Maryland, Panel Calls for Better Training on Disabilities

Image
Commission to create recommendations for policy, training..... Ethan Saylor: Down Syndrome Maryland law enforcement workers need more guidance in dealing with individuals with intellectual and developmental disabilities, according to a commission formed after a man with Down syndrome died in a struggle with Frederick County sheriff's deputies.     Gov. Martin O'Malley created the Commission for Effective Community Inclusion of Individuals with Intellectual and Developmental Disabilities in September after Robert "Ethan" Saylor, 26, died Jan. 12 when deputies attempted to remove him from a Frederick movie theater. "Current training of law enforcement personnel in Maryland on how best to interact with individuals with intellectual and developmental disabilities is not offered in every jurisdiction and what is provided is inconsistent and not comprehensive," the commission wrote in a progress report released Thursday. The commission also
