Down Syndrome (Intellectual Disability)

Down Syndrome occurs when there is a full or partial extra copy of chromosome 21. This additional genetic material alters the course of development and produces common traits for children with Down Syndrome. A few common physical traits that occur are low muscle tone, low strength, difficulty attaining normal development milestones, walking difficulties and looseness of ligaments. Children with Down Syndrome most often have cognitive and neurological delays with difficulty processing normal activities. However, this is usually mild to moderate, affecting normal tasks and interactions.
