The first three years of life are a critical period for development. The environmental stimuli have positive effects on the development of speech and language. Language skill involves the development of expressive and receptive skills among children. Speech and language disorders, during childhood, have important negative outcomes in the life of the child. So, early detection of children at risk in the preliminary phases of development and starting the early intervention for them is very important. The aim of this case study was to investigate the effect of early language intervention in children with a developmental language disorder(DLD).
A twenty-seven-month-old child diagnosed with an autism spectrum disorder was conducted in this case study. Occupation and speech therapy was performed for him. Results showed that the early intervention was essential for improving the child's communication, and proper environmental stimuli could prevent possible problems in the future. In addition, the result revealed that the child professionals should not wait and see for improving development.
