In July 2009, researchers from the University College of Medicine, Taoyuan, Taiwan published a study, suggesting that patients with autism should considered a wheat gluten-free and casein-free diet for improvement.
In this study, a 3-year old boy with autism, was diagnosed with CHARGE syndrome and growth and developmental retardation. The researchers put the young boy on wheat gluten-free and casein-free diet.
After 2.5 months, interpersonal relations including eye to eye contact and verbal communication improved. At 5.5 months the boy was capable of playing and sharing toys with his sibling and other children, behavior noted to be closer to that of an unaffected child. He also gained weight and grew in height.
