Lessons in early identification and treatment from a case of disabling vitamin C deficiency in a child with autism spectrum disorder.

BACKGROUND

Autism spectrum disorder is a heterogenous neurodevelopmental condition accompanied by a variety of associated features. Case reports suggest one such associated feature, food selectivity, increases risk for nutritional deficiencies; however, little attention has been given to prevent and treat nutritional deficiencies in youth with autism spectrum disorder.

METHOD: Single case report.

RESULTS

This single case report presents a child with autism spectrum disorder and food selectivity difficulties that resulted in severe vitamin C deficiency. Although eventually corrected, the nutritional deficiency was debilitating, required invasive interventions, and resulted in significant social/emotional and economic costs.

CONCLUSIONS

We review the course of treatment and highlight strategies to prevent and more effectively treat nutritional deficiencies in youth with autism spectrum disorder.
