Autistic children have larger brains. Children with autism have larger brains size up to 10% compared to normal children. This condition can be seen at the time the child turns two years old. As revealed in a report Archives of General Psychiatry, researchers the University of North Carolina found that children with autism have had signs of enlargement of the brain at the age of two years. Their brains are growing at the age of 4 and 5 years.

Brain enlargement occurs because of the increased number of folds of the brain surface due to the increased proliferation of brain neurons. For researchers continue to develop further studies to find out what kind of gene that makes the brain neurons experiencing excessive proliferation. University of North Carolina is currently conducting two separate studies to obtain answers to that question.

Signs of autism can be monitored by continuing to observe the development of a child’s brain size. This effort is important to monitor brain size and behavior change as you age their children. Another research also found many weird syndrome in the world.
