Aspergers is an Autism Spectrum Disorder. It is generally thought to affect far more boys than girls. However, a leading expert on such disorders, Dr. Judith Gould, argues that many girls with Aspergers are not diagnosed. According to Gould, this is because the criteria for diagnosis are based on the ways in which boys manifest the disease, and girls’ symptoms are different. Undiagnosed Aspergers can make life miserable, leading to extremely low self-esteem. It may play a role in anorexia and self-harm in some cases. Here is the Guardian article.
