Is autism a disability..Veil of mystery trigger autism in children are unfolding. The scientists in the latest study found that autistic children generally have more severe brain and brain cells overload autism disabilities .
For more than a decade scientists have long suspected that autism is caused by a disability for autism growth disorder and abnormal brain development.
Is autism a disability or disorder. Previous studies showed that children with autism have a larger head size and brain. Besides the important parts of the brain to process emotions, developing communication and social excess. In a recent study published in the Journal of the American Medical Association, the scientists confirmed it.
autism developmental disabilities, The study was conducted in the brains of 13 boys aged 2-16 years. Donated their brains for research after the children died. Using microscopic techniques the researchers calculated the number of brain cells or neurons in the brain children. A total of 7 children and 6 children with autism do not.
The scientists found that the brains of children with autism have neurons in the prefrontal cortex area 67 percent more. The area associated with social functioning, emotional and communication processes, functions that are impaired in children with autism. autism a disability..Brains of children with autism also have a 17.5 percent heavier weight than children without the disorder.
According to Eric Courchesne, lead researcher, developments in the area of prefrontal cortex neurons occurs during pregnancy. autism a disability , As the fetus develops in the womb occurs excessive growth of brain cells, especially in the age of 10-20 weeks of gestation. Growth was followed by an explosion and a half brain cells die so that at birth the baby had a normal brain size.
Scientists say the cycle makes the brain regulates itself and the brain cells are connected to each other with each other. But if there is excessive growth, the connections between brain cells will be disrupted.
"It's a lot of evidence to suggest a connection between brain cells is impaired in children with autism. If the number of neurons were dying how they are connected," said Dr. Kate McFadden, neuropathologis from the University of Pittsburgh Medical Center.
is autism a mental disability. Experts remind that this research is still in its early stages and can not be applied to children and families who now have autism. However, the results of the research will open a new hope right way to detect autism.
