Down sendromu, also known as Down syndrome, is a genetic condition caused by the presence of an extra copy of chromosome 21. This extra genetic material affects physical and intellectual development, leading to characteristic features such as a flat facial profile, slanted eyes, and a shorter stature. Individuals with Down syndrome may also experience varying degrees of cognitive impairment. People with Down syndrome can lead fulfilling lives and often participate in education, work, and social activities. Early intervention programs, including speech and physical therapy, can help improve their skills and independence. Support from family and the community plays a crucial role in their development and well-being.
