Down Syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21. This additional genetic material leads to developmental delays, intellectual disabilities, and distinct physical features such as a flat facial profile and upward-slanting eyes. Individuals with Down Syndrome may also experience health issues such as heart defects, thyroid problems, and increased risk of respiratory infections. Early intervention programs, educational support, and medical management can help individuals with Down Syndrome reach their full potential and lead fulfilling lives within their capabilities.
