The result is known after a study of 383 young women who are diagnosed with autism. At the age of 2 years, every child is given assessment autistic behavior such as avoiding the gaze of others.

"Autism is a condition that is actually dominated by men. Counted, the proportion of people men and women that is 4:1," he said, as quoted by The Australian, Monday (7/2).
