The human body relies on a person having the exact number of chromosomes for proper functioning. However, sometimes, a baby has an extra chromosome, which can lead to several birth defects and mild to severe physical and developmental defects. One of these conditions is Down Syndrome, also known as trisomy 21, as the condition is caused by one having three copies of the 21st chromosome. Here’s more about what down syndrome is, what causes down syndrome, symptoms of down syndrome, screening, etc.
Down Syndrome is a genetic condition that is a result of abnormal cell division that causes one to have an extra partial or full copy of chromosome 21. Down syndrome is a common genetic chromosomal disorder. It results in lifelong developmental delays and intellectual disabilities, the severity of which may vary from person to person. Screening and early diagnosis of down syndrome and getting the right care can make a huge difference in helping children with down syndrome live full, healthy lives.
The severity of the effects of down syndrome are different for different people. The signs and symptoms of down syndrome are generally associated with intellectual disabilities, characteristic facial features, and hypotonia or weak muscle tone during infancy. While almost all individuals with down syndrome will experience cognitive delays, the intellectual disabilities they experience can vary from mild to moderate issues with reasoning, thinking, and understanding. People with down syndrome will be able to learn new skills throughout their lives but may take longer to cross important milestones like talking, walking, developing social skills, etc.
Certain common physical features are also signs of down syndrome, and may include:
Many people with Down syndrome do not have other health issues, while some may suffer from cardiovascular conditions or may have issues with seeing and hearing.
Both parents pass their genes onto a baby, carried in chromosomes. When the cells of a baby are developing, each is supposed to receive 23 pairs of chromosomes (46 in total), where half comes from the mother and half from the father. In down syndrome, one of the chromosomes does not separate properly and the baby ends up with an extra chromosome 21, which leads to the common issues of down syndrome.
Parents with higher risks should be on the lookout for signs of down syndrome during pregnancy. These risk factors include:
There are several types of tests that may be performed to screen for down syndrome in pregnancy.
With no treatment available, down syndrome is a lifelong condition. However, the right services early in life can help babies with down syndrome improve their intellectual and physical abilities. These services are mostly focused on helping children with down syndrome reach their full potential. They can include:
Remember, children with down syndrome are extremely smart and intelligent in their own right and just need a specialized approach in terms of how they learn.
