Autism is considered one case and has no one reason, as scientists save

New research from Cambridge University indicates that autism should not be understood as a homogeneous condition with one reason. Scientists have found that people who were diagnosed in early childhood often have a genetic image different from those that were later diagnosed in life, which expands understanding how the condition evolves.

the Ticket Analysis of the behavior of people with autism during childhood and adolescence in the United Kingdom and Australia. He also evaluated the genetic data of more than 45,000 patients suffering from the condition of various groups in Europe and the United States.

By linking genetic information to age at diagnosis, the researchers noted that the profiles of those who were identified early on condition differ from those who have received confirmation in later stages. They only found a slight overlap between the two groups, indicating that the biological mechanisms associated with childhood autism may differ from those related to autism specified in adolescence or adulthood.

The analysis, which was published last week in the magazine natureIt was shown that children who were diagnosed before the age of six were more likely to develop behavioral difficulties – such as social interaction problems – from an early age. In contrast, after the age of ten, diagnostic people were likely to face social and behavioral difficulties during adolescence. They also had more willingness to mental health conditions, such as depression.

The study adds that the average genetic file for those wishing later was closer to that ADHD And conditions such as post -traumatic disorder from those of “classic” autism specified in early childhood.

The study concluded that the timing of the diagnosis is not completely random, but it reflects the basic genetic differences that coincide in some cases with the risk of other cases.

“For the first time, we found that autism earlier and then they are diagnosed at a later time and then he has different biological and development profiles,” said Varun Warr, a researcher at the Department of Psychiatry at the University of Cambridge and the author of the newspaper in the paper.
