What are the signs and symptoms of Down syndrome and what can be done to fix it?

See NIH website: See: www. Nchi. Nlm. Nih. Gov/pubmedhealth/pmh0001992/ for a full review.
Down syndrome results when a kid is born with too much chromosome material in his/her cells which confuses the system & results in anomalies & poor development. It cannot be fixed, but outcome can be improved with attention to associated problems. ...Read more

What are the fetal sign and symptoms of down syndrome?

What are the fetal sign and symptoms of down syndrome?

Maternal serum: Screening at 10-14 weeks + fetal ultrasound (fus) at 11-14 weeks + maternal "quad" screen at 16 weeks detects ~ 95% of fetuses with Down syndrome with <5% false-positive rate. Increased size of the fluid-filled space at the nape of the neck & abnormalities of blood flow in the heart are signs on early fus. Diagnostic testing is chorionic villus sampling at 10-12 weeks or amnio at 15-18 weeks. ...Read more

What causes down syndrome?

DNA defects: Chromosome 21 seems to be the cause. Two most common types are trisomy 21 where ther is an entire extra chromosome in each cell. The other is translocation where only an extra piece of the chromosome is found. It can be an isolated defect or an inherited defect. Rare exotic forms include polyploidy and haploid forms and chimeras. Sorry you asked? ...Read more

Why are women the cause of Down syndrome more often than men are?

Why are women the cause of Down syndrome more often than men are?

Non dysjunction: This term means that one of the earliest divisions of the embryo after conception delivers 3 number 5 chromosomes to a daughter cell and only one to the other daughter cell. The trisomy cell survives to create down's syndrome babies. ...Read more

I'm wondering why are women the cause of Down syndrome more often than men?

Selection variables: If a woman generates an egg that contains 2 rather than 1 chromosome 21's, the addition of a 21 from the sperm will cause the trisomy 21 condition. Some of these miscarry & some deliver. When males generate a sperm that carries irregular information, there is speculation that the ones with bad information do not swim as well & thus can't pass the defect. ...Read more

What are the causes of people with Down syndrome to live fifty years or less?

Poor health: The expected lifespan of a ds patient born today exceeds 60 years if they have access to the basic medical care & dietary resources of average individuals. They do have higher risks for a variety of health issues involving their glands (thyroid, diabetes) their bones (scoliosis, joint pain & weakness) and the impact of obesity is much worse for their overall health. ...Read more

What are the causes of people to be born with down syndrome?

What are the causes of people to be born with down syndrome?

Extra chromosome 21: A woman's chances of giving birth to a child with Down syndrome increase with age because older eggs have a greater risk of improper chromosome division. By age 35, a woman's risk of conceiving a child with Down syndrome is 1 in 400. By age 45, the risk is 1 in 35. However, most children with Down syndrome are actually born to women under age 35 because younger women have far more babies. ...Read more

What are some of the causes for a child to be born with down syndrome?

What are some of the causes for a child to be born with down syndrome?

Several possible: The features of Down syndrome are dependent on the addition of one extra segment of a 21 chromosome which is more likely as women age. You can get this several ways. The traditional DS (~95%) has 3 copies of a 21 chromosome. About 4% have the specific extra 21 piece stuck on a regular chromosome (trans-location).About 1% have a mosaic of some normal and some 21 trisomy in variable amounts. ...Read more
