Down Syndrome Overview

Down syndrome is a chromosomal condition that arises when chromosome 21 is overexpressed, most commonly due to trisomy 21, but sometimes because of mosaicism or chromosomal translocation. Beyond developmental differences, emerging research shows that this extra genetic material alters cellular metabolism, immune function, and brain aging, helping explain why individuals with Down syndrome have a higher risk of autoimmune disorders and early-onset Alzheimer’s disease. At the same time, advances in prenatal screening, cardiac care, and early neurodevelopmental therapies have dramatically improved life expectancy and functional independence, shifting the focus from survival to long-term cognitive health, social inclusion, and personalized medical care.
