Abstract

Interest in the link between Autism Spectrum Disorder (ASD) and Anorexia Nervosa (AN) has led to estimates of the prevalence of autistic traits in AN. This systematic review and meta-analysis assessed the use of the Autism-Spectrum Quotient (AQ) or abbreviated version (AQ-10) to examine whether patients with AN have elevated levels of autistic traits. Seven studies were identified and subsequent meta-analysis indicated that those with AN appear to have significant difficulties of a manner characteristic of ASD, relative to controls. Whilst this analysis supports previous indications of higher prevalence of ASD in AN, the aetiology of these traits remains unclear. Studies using more robust clinical measures of ASD within AN are needed to confirm what self-report measures appear to show.

Autism

Autism spectrum disorder is associated with challenges with social skills, repetitive behaviors, and often accompanied by sensory sensitivities and medical issues. Here is the latest research.

Autism: Treatment Targets

The absence of effective treatments for autism are due to the high clinical and genetic heterogeneity between affected individuals, restricted knowledge of the underlying pathophysiological mechanisms, and the lack of reliable diagnostic biomarkers. Identification of more homogenous biological subgroups is therefore essential for the development of novel treatments based on the molecular mechanisms underpinning autism and autism spectrum disorders. Find the latest research on autism treatment targets here.

Anorexia Nervosa

Anorexia nervosa (AN) is a psychiatric condition characterized by severe weight loss and secondary problems associated with malnutrition. Here is the latest research on AN.
