Background: Autism spectrum disorders (ASD) have been suggested to be overrepresented in anorexia nervosa. This study aimed to explore the comorbidity of ASD and other childhood onset neuropsychiatric disorders (COND) [attention-deficit/hyperactivity disorder (AD/HD) and tic disorders] in a group of severe eating disorder (ED) patients.
Method: Thirty female ED patients from a specialist hospital clinic were examined on measures tapping into COND and personality disorders.
Results: In our group of longstanding ED, 53% had at least one COND diagnosis; 23% had ASD, 17% had AD/HD, and 27% had a tic disorder.
Conclusions: These preliminary data suggest that COND may be common in patients with severe ED and should be kept in mind when treating these patients.
