Autism Research Center at Philadelphia Children’s Hospital in the US.Changes in the brain of children under one year of age can predict autism.
Autism Detectable Before Two Years of the Child
The autism is often detected around two years in a child.
Yet it would be possible to diagnose the disease even earlier. This is in any case what reveals a study published in the journal Nature.
Autism-related disorders could be detected well before the onset of symptoms.
By combining cerebral magnetic resonance imaging (MRI) of babies with mathematical algorithms.
To reach this conclusion the researchers followed a hundred .So babies who were at risk of having autism.
Because their older brother or sister was autistic. In the case of an autistic elder.
The risk of developing the disease can be multiplied by five.
Their brains were examined by MRI between their 6th month and their 2nd year .
About 40 babies with low autism risk were also examined.
Fast brain growth
The researchers found that in children who were later diagnosed.
He surface of the cortex, that is, the superficial layer of the brain,had grown faster than other children. They also observed that the brain volume of these children.Who were going to become autistic increased very rapidly between one and two years .
By measuring the surface and volume of the brain.As well as the thickness of the cortex, researchers were able to calculate the risk of autism for each child through mathematical modeling. A statistical approach that proved to be accurate in 90% of cases .
Reverse Cellular Deficits
Zinc, a trace element essential for children’s growth.Reverse the expression of a gene.the Shank3, which is damaged in people . This is revealed by a study, published in the journal The Journal of Neuroscience . The researchers found that zinc can reverse communication deficits between brain cells in animals.
” Autism is associated with genetic changes that cause changes in behavior, “.
