Down syndrome is a genetic disorder that presents itself right at the event of a child’s conception if said child has an excess amount of a particular portion of the genetic code embedded in its genetic makeup. Down syndrome occurs in about 0.13% of all live births and can manifest as physical growth defects, general mental slowness, and excessively impulsive behavior as the afflicted child matures. This genetic defect may also result in the loss of a pregnancy before birth as certain key developmental stages during pregnancy are perhaps significantly altered or hindered. Interestingly, this defect is more common with mothers that are of a relatively advanced age. Studies have shown that the frequency of down syndrome related pregnancies actually increases to ~1% in mothers that are 35 years of age or older. In our modern world where most women spend their 20s building careers, a lot of families now routinely have children while the childbearing mother is in her 30s and beyond. Thankfully, advances in modern medicine have yielded minimally invasive screening and diagnostic techniques that can tell a family with a high degree of certainty whether or not the current pregnancy is associated with a child afflicted by down syndrome.
