What is a common characteristic of individuals with Down syndrome?

Individuals with Down syndrome typically exhibit hypotonic muscle tone, which is characterized by decreased muscle strength and reduced resistance to passive movement. This hypotonia can impact a variety of physical and developmental areas, often affecting motor skills and coordination. As a result, children with Down syndrome may experience delays in reaching developmental milestones such as sitting, crawling, and walking.

Hypotonic muscle tone is a common finding due to the unique genetic factors associated with Down syndrome, specifically the presence of an extra copy of chromosome 21. This condition alters muscle function, leading to the characteristic low muscle tone seen in many individuals with Down syndrome. The implications of hypotonia extend to speech and language development as well, potentially affecting articulation and oral motor skills. Understanding this aspect is crucial for developing effective therapeutic interventions and support systems for individuals with Down syndrome.
