Autism is a very complex developmental disorder in children, whose symptoms had occurred before the child reaches 3-4 years of age, FOR the first time, scientists have discovered a method that can accurately identify biological markers of autism in very young toddlers, through subjective tests and based on behavioral symptoms. By scanning the brain activity of children when sleeping.
The cause of autism is a neurobiological disorder that affects brain function in such a way that children are not able to interact and communicate with the outside world effectively. Symptoms are very prominent is the attitude of children who tend not to care about the environment and the people around him, as if refusing to communicate and interact, as well as live in his own world. Children with autism also have difficulty understanding the language and communicate verbally. Besides, often (self-stimulation behaviors) such as spinning, flapping-wing ngepakan hands like, walking on tiptoes, and so forth.
Symptoms of autism vary widely. Some children are hyperactive and aggressive behavior or self-harm, but some are passive. They tend to be very difficult to control his emotions and often tempertantrum (crying and raging). Sometimes they cry, laugh or get angry for no apparent reason. In addition to the symptoms vary in type, intensity of symptoms of autism also vary, from very mild to very severe.
Because of the many differences between each individual, then this is more common developmental disorders known as Autistic Spectrum Disorder (ASD) or Autistic Spectrum Disorders (GSA). scientists at the Weizmann Institute of Science Mellon, Carnegie University and the University of California, San Diego, found that the brains of autistic children have a significantly weaker synchronization in brain regions associated with language and communication when compared with children who nonautistik.
“Identifying the biological markers of autism has become a major destination for many scientists around the world, either because they can allow early diagnosis and because they can give researchers important clues about the causes and progression of these disorders,” said Dr. Ilan Dinstein involved in this study . In the autistic toddler bed, the scans show the level of synchronization between the left and right brain regions associated with language and communication skills decline.
This pattern was not seen in children with normal development or in those with language development is delayed but not autistic. In fact, the researchers found that the synchronization is strongly associated with the autistic child’s ability to communicate. The weaker the synchronization, the more severe are the symptoms of autism. Based on the results of the scan anyway, the scientists were able to identify 70 percent of autistic children between ages 1 and 3 years.
