Trisomy 21, also known as Down syndrome (DS), is caused by an additional copy of chromosome 21, making it the most common chromosomal anomaly related to this chromosome. It is characterized by cognitive impairment and a variety of comorbid conditions. Medical advancements have greatly improved the lifespan of those with DS, yet they face numerous health challenges, including heart defects, respiratory issues, obstructive sleep apnea, atlantoaxial joint instability, obesity, craniofacial abnormalities, and various mental and behavioral disorders, complicating anesthesia management.
Down syndrome is associated with distinct physical characteristics, developmental delays, and a higher risk of certain medical conditions. Affected individuals display unique facial features and may experience hindered physical and intellectual growth. Intellectual disabilities vary, with some individuals experiencing mild to moderate impairments. Early intervention, including speech, occupational, and physical therapy, is crucial in enhancing their abilities.
Characteristic Features: People with DS may have a flat facial profile, slanted eyes, low muscle tone, and a singular deep palm crease known as the "Simian crease." Growth often lags, resulting in a shorter stature.
Developmental Delays: Intellectual development in individuals with DS ranges widely but tends to be mild to moderate. Engaging in early intervention therapies can significantly boost their developmental potential.
