Causes of Down syndrome

What causes Down syndrome in children? A little known fact is that when a baby was born he receives genetic information from his parents under the form of 46 chromosomes, divided, 23 from the mother and 23 from the dad. Down syndrome appears when the child gets 47 instead of the usual number of 46 because he gets extra material which he doesn’t need, slowing his developing as it confuses the body.

When pregnant, your doctor may suggest you take a screening test or a diagnostic test in order to see if your child has the syndrome. A screening test sends ultrasounds that decides if your child has Down syndrome, although sometimes it may give results such as false-positive or false-negative.

There are no cures for down syndrome and there’s no way to stop it, it has been shown by scientists that women older than 35 have a higher risk to born a child with this syndrome as there is the chance of 1 in 400.

There are many types of this disease, as it is for all of them.

The most usual one is Trisomy 21, the one that’s very usual for children. For the Trisomy 21 condition, the cells have 3 separate copies of each other rather than the usual 2.

Translocation Down syndrome, this condition happens to a small amount of people, and a very low amount of children (about 3%). This happens when an extra part or a whole extra chromosome is present, but attached to a different one rather than being a separate cell.

Mosaic Down syndrome this type accounts only for 2% of people, and there were just about 3 cases for children. The name is actually a combination of meanings, Mosaic meaning mixture or combination. For children with this condition, only some of their cells have 3 copies and the rest has the normal 2 copies. This condition is close to the normal Trisomy 21 as children may have the same features as the ones with Trisomy 21.

Down syndrome is a condition that lasts your entire life. Treatments early in life will most likely help babies and children with this syndrome in order to improve their physical and intellectual abilities. Most of these treatments, you can call them also services, have the target to develop children with Down syndrome to their full potential. They include speech, occupational and physical therapy and they are usually offered by the state.
