The study published earlier this week in the BioMed Central Journal Molecular Autism, looked at traits in 66 young women ages between 12 and 18, who had not been diagnosed with Autism, or an Autistic Spectrum Disorder (ASD). The researchers compared them to more than 1,600 typical teenagers in the same age range, measuring their autistic traits using a score called the Autism Spectrum Quotient (AQ), their “systemising” using the Systemising Quotient (SQ), and their empathy using the Empathy Quotient (EQ).
The girls who had been diagnosed with Anorexia Nervosa scored five times the average AQ score, which is where an individual with a High Functioning ASD would usually score. It seems that a number of these girls have been misdiagnosed as they see members of the medical community first for their anorexia.
Speaking to Reuters earlier this week, Mr Baron-Cohen said:
“But this new research is suggesting that underlying the surface behavior, the mind of a person with anorexia may share a lot with the mind of a person with autism. In both conditions, there is a strong interest in systems. In girls with anorexia, they have latched onto a system that concerns body weight, shape, and food intake.”
The exact triggers for Anorexia Nervosa have never been found. It is thought to be triggered by a number of psychological, psychological and environmental factors surrounding the individual.
Co-author of the study Tony Jaffa said:
“Shifting their interest away from body weight and dieting on to a different but equally systematic topic may be helpful. Recognizing that some patients with anorexia may also need help with social skills and communication, and with adapting to change, also gives us a new treatment angle.”
