This final thesis explores the communication challenges and potentials of children with syndrome Down. The focus of the paper is to understand how children with syndrome Down communicate, identify the barriers they encounter, and review strategies for improving communication in children through a comprehensive study. Children with syndrome Down can make significant progress in communication with appropriate support. The most common barriers include difficulties in language comprehension, expression, articulation, and establishing social connections. However, by implementing different strategies such as early interventions, the use of visual aids, individualized approaches, and family support, it is possible to promote the communication development of children with syndrome Down. The conclusion of this paper emphasizes the importance of early intervention and support in the development of communication skills in children with syndrome Down. Individualized approaches, structured learning methods, the use of augmentative and alternative communication, and collaboration between parents and professionals are key factors in achieving success in communicating with children with syndrome Down. Enhancing communication skills in children with syndrome Down has an extremely positive impact on their development, socialization, and quality of life.
