Why autism is more common in males

Why autism is more common in malesWashington, Feb. 28 - Males are at greater risk for neurodevelopmental disorders, such as autism spectrum disorder (ASD), than females, but the underlying reasons have been unclear.

Now, a new study has provided compelling evidence in support of the 'female protective model,' which proposes that females require more extreme genetic mutations than do males to push them over the diagnostic threshold for neurodevelopmental disorders.


New 'groundbreaking' breakthrough links autism symptoms to gut microbes

New 'groundbreaking' breakthrough links autism symptoms to gut microbesWashington, Dec. 20 - Researchers have shown that feeding mice a beneficial type of bacteria can ameliorate autism-like symptoms.

Researchers found this in children of mothers with elevated C-reactive protein (CRP), a well-established marker of systemic inflammation.


Autism impairs kids’ motor skills

Autism impairs kids’ motor skillsWashington, Feb 16 : Autism hampers the development of motor skills in children, say scientists.

Autistic kids often have problems developing motor skills, such as running, throwing a ball or even learning how to write. But scientists have not known whether those difficulties run in families or are linked to autism.

Now, new research at Washington University School of Medicine in St. Louis points to autism as the culprit.


Babies born to older mum or dad likelier to suffer from autism

Babies born to older mum or dad likelier to suffer from autism London, Feb 6 : Children are more susceptible to autism if either of their parents is older than 35 at the time of conception, researchers say.

The findings have come as a surprise as it was previously thought that delaying motherhood represented the greatest risk.


New method detects biological sign of autism in young toddlers

 New method detects biological sign of autism in young toddlers Washington, July 26: For the first time, scientists have found a method that can accurately identify a biological sign of autism in very young toddlers.

Until know the biological causes of autism were not understood and diagnosis of autism was only possible after ages three or four; and the tests are subjective, based on behavioural symptoms.


Weaker brain ''sync'' may be new biological marker of autism

 Weaker brain ''sync'' may be new biological marker of autismWashington, June 23: A diminished ability of a young brain''s hemispheres to `sync' with one another could be a powerful, new biological marker of autism, according to scientists at the University of California,
San Diego Autism Center of Excellence.

With this novel imaging study of sleeping toddlers, one might enable an autism diagnosis at a very young age.


Autism more common in IT-rich regions, finds study

 Autism more common in IT-rich regions, finds study Washington, June 21: There will be a higher rate of autism among their children whose parents gravitate towards jobs that involve strong ‘systemizing’, such as the IT sector, a new study from Cambridge University has found.

The study has important implications for service provision in different regions and for the ‘hyper-systemizing’ theory of autism.


Genes associated with autism spectrum disorder revealed

 Genes associated with autism spectrum disorder revealedWashington, June 9 : A study has described the network that identifies hundreds of new interactions among proteins encoded by genes associated with autism spectrum disorder.


Autism may have played important role in human’s hunter-gatherer past

 Autism may have played important role in human’s hunter-gatherer pastWashington, June 6 : A study has found that people with autism may have been capable hunter-gatherers in prehistoric times.

Jared Reser, a brain science researcher and doctoral candidate in the USC Psychology Department, said the autism spectrum might represent not disease, but an ancient way of life for a minority of ancestral humans, Science Daily reported.


Functional magnetic resonance imaging may improve diagnosis of autism

Functional magnetic resonance imaging may improve diagnosis of autismWashington, May 31: Functional magnetic resonance imaging (fMRI) may provide an early and objective indicator of autism.

Researchers at Columbia University in New York City used the technique to document language impairment in autistic children.

Autism is a spectrum disorder characterized by repetitive behaviours and impaired language, communication and social interactions.


Kids conceived in winter have a greater risk of autism

 Kids conceived in winter have a greater risk of autism Washington, May 06 : A study has found that children who are conceived during winter have significantly greater risk of autism.

An examination of the birth records of the more than 7million children born in the state of California during the 1990s and early 2000s has found a clear link between the month in which a child is conceived and the risk of that child later receiving a diagnosis of autism.


Gene linked to severity of autism''s social dysfunction identified

 Gene linked to severity of autism''s social dysfunction identified Washington, Apr 7 : Johns Hopkins scientists have identified a gene associated with autism that appears to be linked very specifically to the severity of social interaction deficits.

The gene, GRIP1 (glutamate receptor interacting protein 1), is a blueprint for a traffic-directing protein at synapses — those specialized contact points between brain cells across which chemical signals flow.


Drug used to treat alcoholism may help those with Fragile X, autism

Washington, April 05: In a new study, adults and children with autism and Fragile X syndrome have shown improved communication and social behavior when treated with acamprosate.

Acamprosate, which affects chemicals in the brain by blocking certain receptors associated with mental health, has approval from the Food and Drug Administration for the treatment of alcoholism in adults.


Serotonin may play role in autism

 Serotonin may play role in autism Washington, Feb 25: A new study has suggested that serotonin plays a vital role in autism spectrum disorders.
