Symptoms in Boys vs. Girls.
Autism is diagnosed in boys 4 times more often than in girls. This can be explained by the fact the disorder looks different in girls and, therefore, is often left unnoticed.
Boys with autism tend to show overt symptoms such as pacing or rocking. They are normally very loud and get upset or angry easily if they are involved in some activity outside their comfort zone. Their behavior is more likely to draw the attention of parents, teachers and doctors.
Girls with autism, on the contrary, are usually quiet, withdrawn, and unwilling to participate in activities involving other children. Such behavior can be easily mistaken for shyness or normal social reticence you would often expect to see in girls. As a result, they do not get duly diagnosed. [7, 8]
Of course, this is not true for everyone and there might be individual variations.
