Down Syndrome, also known as trisomy 21, is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21. It is typically associated with physical growth delays, intellectual impairment, and communication delays. Children with Down Syndrome (DS) are usually good communicators. However, clear speech is more difficult and therefore, speech can be a challenge. Children with Down Syndrome also typically also present with motor and muscle tone issues impacting their development.
