How To Recognize And Diagnose Down Syndrome In Kids

Let us understand Down Syndrome, here is how to identify and diagnose this condition in children.

Down syndrome is a genetic condition that occurs when a child is born with an additional chromosome. The additional chromosome influences the development of the child's brain and body, resulting in developmental delays, intellectual disability, and a heightened risk of specific medical problems. Down syndrome is typically not passed down through generations. It occurs randomly, as a mistake when cells are dividing in the early stages of fetal development. The exact reasons for the occurrence of Down syndrome and the number of contributing factors are not definitively established. The mother's age is a contributing factor to the risk of having a child with Down syndrome. The likelihood of having a Down syndrome baby increases for women aged 35 and over.

Understand Down Syndrome

While many lead healthy and fulfilling lives, some may experience additional medical challenges. Along with mild to moderate intellectual disabilities and developmental delays, individuals with Down syndrome often have distinct physical features, such as a flat facial profile, upward-slanting eyes, and small hands and feet. They may also be at a higher risk for certain health conditions, including hearing loss, recurrent ear infections, sleep apnea, and congenital heart defects. Additionally, some may experience digestive concerns, spinal issues, or a tendency toward obesity.

"However, with early intervention, specialized care, and a supportive environment, individuals with Down syndrome can achieve significant milestones, lead independent lives, and make meaningful contributions to society. A remarkable example is ngela Bachiller from Spain, who became the first person with Down syndrome to hold a public office in Europe when she was elected as a city councilor in Valladolid. Stories like hers highlight the importance of inclusion and the potential of individuals with Down syndrome to break barriers and inspire change," said Dr Anup Rawool, Consultant - Medical Genetics, Jupiter Hospital, Baner, Pune.

How To Identify Down Syndrome?

Healthcare providers can check for Down syndrome either during pregnancy or after the child's birth. Understanding and diagnosing children with Down syndrome early can make a significant difference in improving their quality of life. Because each child with Down syndrome is unique, treatment will depend on their specific needs.

Dr Sunita Kapoor, Director & Laboratory Head, City X-Ray and Scan Clinic Pvt. Ltd. said, "while a prenatal screening test can indicate a higher probability of a fetus having Down syndrome, it cannot confirm its presence. When a screening test indicates a higher probability, a diagnostic test can be requested. A prenatal invasive diagnostic test can confirm the presence of Down syndrome with complete certainty but the limitation is that Invasive diagnostic tests pose a slightly higher risk to the fetus compared to screening tests."

Furthermore, she added, " At birth, the condition is typically recognized through specific physical characteristics, including low muscle tone, a single deep palm crease, a slightly flattened facial profile, and eyes that slant upward. Since these characteristics can occur in infants who do not have Down syndrome, a chromosomal examination known as a karyotype is performed to verify the diagnosis.

Doctors take a blood sample to analyze the baby's cells to obtain a karyotype. The chromosomes are photographed and subsequently organized according to size, quantity, and shape. Doctors can diagnose Down syndrome through examination of the karyotype. Another genetic test, known as fluorescence in situ hybridization (FISH), can confirm a diagnosis more quickly by visualizing and mapping the genetic material within an individual's cells."

With medical attention, education, and therapy, individuals with Down syndrome can overcome challenges and reach their full potential.
