Children Facial Features Autism

Children Facial Features AutismChildren Facial Features Autism, Scientists can not agree on what causes autism, but a new study thatanlyzed the facial characteristics of children may help researchers understand the origins of developmental disorder.

The study found that children with autism have clear differences in facial features of children with typical development.

“There is no clear answer whether autism is caused by genetics or environmental factors,” said study author Dr. Kristina Aldridge, associate professor of anatomy at the University of Missouri School of Medicine, said in a statement. “If we can identify when these facial changes occur, we could pinpoint when autism can begin to develop in a child.”

For the study – published in the October 14 edition of Molecular Autism – the researchers compared the facial features of 64 children with autism with the faces of 41 children with normal development, all aged 8-12 years, with a system 3-D cameras. After drawing 17 points on the face, the researchers found significant differences between the two groups.

The study found that children with autism had larger eyes, and a “face broader than” compared with typically developing children. According to the study, children with autism also had a shorter median area of ??the face – including the nose and cheeks – and a wide mouth and nasolabial fold, the chop on the lip and below the nose.

The study also found that children with more severe autism traits such as behavior problems, language difficulties, and repetitive behaviors had clear facial differences from other children with mild autism.

Aldridge said that determine when these changes occur will allow researchers to focus on finding the causes of underlying disorders.

“Knowing that point in time can lead us to identify a genetic cause, a window of time when the embryo can be susceptible to an environmental factor, or both,” he said.

One in every 110 children has an autism spectrum disorder (ASD). People with ASD may have difficulties with social interaction, communication, intelligence, or behavior.
