What is down syndrome disorder? Down syndrome is a condition in which a person has an extra chromosome. Chromosomes are small “packages” of genes in the body. They determine how a baby’s body forms and functions as it grows during pregnancy and after birth. Typically, a baby is born with 46 chromosomes.
What causes Down syndrome? About 95 percent of the time, Down syndrome is caused by trisomy 21 — the person has three copies of chromosome 21, instead of the usual two copies, in all cells. This is caused by abnormal cell division during the development of the sperm cell or the egg cell.
What are the four symptoms of Down syndrome? Short neck, with excess skin at the back of the neck. Flattened facial profile and nose. Small head, ears, and mouth. Upward slanting eyes, often with a skin fold that comes out from the upper eyelid and covers the inner corner of the eye.
How does Down syndrome affect a person? An individual with Down syndrome inherits all or part of an extra copy of Chromosome 21. Symptoms associated with the syndrome include mental retardation, distinctive facial characteristics, and increased risk for heart defects and digestive problems, which can range from mild to severe.

When do they test for down syndrome after birth?
A screening test for Down’s syndrome, Edwards’ syndrome and Patau’s syndrome is available between weeks 10 and 14 of pregnancy. It’s called the combined test because it combines an ultrasound scan with a blood test. The blood test can be carried out at the same time as the 12-week scan.
What to do if you have neuroleptic malignant syndrome?
In more severe cases of NMS, empiric pharmacologic therapy is typically tried. The two most frequently used medications are bromocriptine mesylate, a dopamine agonist, and dantrolene sodium, a muscle relaxant that works by inhibiting calcium release from the sarcoplasmic reticulum.
Is gestational diabetes linked to down syndrome?
There have been few human studies of the effect of diabetes mellitus or gestational diabetes on the risk of chromosomal anomalies, although a limited body of data suggests that there is an increased risk of Down’s syndrome among women with either preexisting diabetes or gestational diabetes (31, 32).
What are extrapyramidal syndrome effects?
Antipsychotic medications commonly produce extrapyramidal symptoms as side effects. The extrapyramidal symptoms include acute dyskinesias and dystonic reactions, tardive dyskinesia, Parkinsonism, akinesia, akathisia, and neuroleptic malignant syndrome.

What is nerve compression syndrome?
Nerve compression syndrome occurs when a nerve is squeezed or compacted. It typically occurs at a single location. Nerves in the torso, limbs, and extremities may be affected. Common symptoms include pain, numbness, and muscle weakness at the site of the nerve.
What is robertsonian translocation down syndrome?
The Robertsonian translocation is unbalanced and the baby has three copies of the long arm of chromosome 21 instead of two. This causes a type of Down’s syndrome called translocation Down’s syndrome. The effects on the baby are exactly the same as when Down’s syndrome is caused by having an extra entire chromosome 21.
