The number of eating disorder diagnoses in Ireland has risen by more than 30% in the last year, coinciding with growing awareness of the connection between eating disorders and neurodiversity, according to recent figures.
Research indicates that individuals with autism and ADHD are four times more likely to develop an eating disorder compared to the general population. However, the reasons behind this disproportionate risk are often distinct from those typically associated with eating disorders, such as body image concerns.
For many, the link manifests in everyday experiences: restrictive eating driven by sensory sensitivities, rigid food routines providing a sense of control, or fluctuating eating patterns linked to difficulties with emotional regulation. These experiences often go unrecognized within traditional eating disorder frameworks.
Experts emphasize that, for neurodivergent individuals, food and disordered eating are frequently connected to sensory processing, the need for routine and predictability, anxiety reduction, and coping with trauma. Autistic individuals may find comfort in the structure that an eating disorder provides, offering a set of rules to follow in a world that often feels chaotic and uncertain. The intense focus on food, calorie counting, or specific diets can similarly become a special interest, a common characteristic of the autistic monotropic brain.
Individuals with ADHD may turn to food as a way to manage dopamine dysregulation, a core feature of the condition. Dopamine, a neurotransmitter associated with pleasure and reward, is often lower in individuals with ADHD, leading them to seek stimulation through food. Difficulties with organization and time management can also contribute to irregular eating patterns and cycles of binge eating.
It is crucial to note that these characteristics do not automatically equate to an eating disorder, and should not be pathologized when they are not causing harm. However, understanding these potential contributing factors is essential for effective treatment and recovery.
Professionals are increasingly advocating for neurodivergent individuals with eating disorders to seek treatment from specialists who have a strong understanding of both conditions. Treatment should focus on addressing the underlying factors contributing to the disordered eating, while avoiding the pathologization of neurodivergent traits. Recognizing undiagnosed neurodivergence in individuals presenting with eating disorders can also significantly improve treatment outcomes.
Eating Disorders Awareness Week begins February 20.
