Down Syndrome By Leslie Campos

Definition- a congenital disorder arising from a chromosome defect, causing intellectual impairment and physical abnormalities including short stature and a broad facial profile. It arises from a defect involving chromosome 21, usually an extra copy.

Cause of down syndrome-Trisomy 21 is caused by an error in cell division called nondisjunction, which leaves a sperm or egg cell with an extra copy of chromosome 21 before or at conception

Statistics-Each year about 6,000 babies are born with down syndrome, Between 1979 and 2003 the number of babies born with down syndrome increased 30

How is down syndrome detected- They detect it down syndome by screening test and blood test, diagnostic tests, such as chorionic villus sampling or amniocentesis.

Birth defect of down syndrome before birth- They do a screening test or cells are taken from the placenta and used to analyze fetal chromosomes.

Birth defect of down syndrome After birth- They are born with an extra copy of chromosomes 21 total.

Treatment-Early intervention programs with a team of therapists and special educators who can treat each child's specific situation are helpful in managing Down syndrome.

Cure- Most notably, heart defects affect approximately 50% of all individual born with Down syndrome. Due to years of research, most heart defects are repaired with relative ease.

Long term effects-Hearing problems, probably caused by repeated ear infections. Hip problems and risk of dislocation. Long-term constipation problems. Sleep apnea (because the mouth, throat, and airway are narrowed in children with Down syndrome).
