The causes and physical and mental effects of down syndrome

Screening tests are cost-effective and easy to perform. This means he or she has no signs or symptoms of Down syndrome, but can pass an unbalanced translocation on to children, causing Down syndrome in the children. This uses results from first-trimester screening tests with or without nuchal translucency and blood tests with a second trimester quadruple screen to come up with the most accurate screening results.

Is born with Down syndrome. There is a small risk of miscarriage with these tests. Severe heart problems may lead to early death. Most of the time, Down syndrome isn't inherited. Commonly, there is a small head and short neck, a flat face, and upward slanting eyes.

Mosaicism Mosaicism occurs when a child is born with an extra chromosome in some but not all of their cells. Children with Down's syndrome are always happy. A blood test that analyzes fetal DNA found in the maternal blood. Birth defects involving the heart, such as an atrial septal defect or ventricular septal defect Dementia may be seen Eye problems, such as cataracts most children with Down syndrome need glasses Early and massive vomiting, which may be a sign of a gastrointestinal blockage, such as esophageal atresia and duodenal atresia Hearing problems, probably caused by repeated ear infections Hip problems and risk of dislocation Long-term chronic constipation problems Sleep apnea because the mouth, throat, and airway are narrowed in children with Down syndrome Teeth that appear later than normal and in a location that may cause problems with chewing Underactive thyroid hypothyroidism Exams and Tests A doctor can often make a diagnosis of Down syndrome at birth based on how the baby looks.

Most children who have Down syndrome are able to attend neighborhood classes and many go on to participate in secondary education. Click here to see a related article about the Genetics of Down's Syndrome.

Effects, Signs & Symptoms of Down Syndrome

Table 2 Table 2a: Early intervention can help the individual maximize their potential and prepare them to take an active role in the community. One in every babies born in the U. Reduced muscle tone which results in floppiness hypotonia ; A flat facial profile, flat nasal bridge, small nose; Eyes that slant upwards and outwards, often with a fold of skin that runs vertically between the lids at the inner corner of the eye epicanthic fold ; A small mouth which makes the tongue seem slightly large; A big space between the first and second toe sandal gap ; Broad hands with short fingers and a little finger that curves inwards.

Apart from physicians, special educators, speech therapists, occupational therapists, physical therapists, and social workers can all help. Click here to see a related article about the History of Down's Syndrome In Professor Jerome Lejeune, a geneticist in Paris, discovered that Down's syndrome occurred as a result of a trisomy of chromosome Screening is a cost-effective and less invasive way to determine if more invasive diagnostic tests are needed.

However, unlike diagnostic tests, they cannot confirm whether Down syndrome is present.

Maternal physical and mental health in children with Down syndrome

These genes are carried in chromosomes. These genes carry our genetic code, which is grouped in rod-like structures called chromosomes, and are the material responsible for all inherited traits.

Joints tend to be more flexible and muscles may lack tone. Screening tests estimate the risk that a fetus has DS; diagnostic tests can tell whether the fetus actually has the condition. Many states provide free early-intervention services to kids with disabilities from birth to age 3, so check with your doctor or a social worker to learn what resources are available in your area.

Down syndrome affects people of all races and socioeconomic levels and while there is not one known cause for DS, it does appear to be related to maternal age at conception.

Because of the abnormal facial anatomy, recurrent ear infections are common and can lead to deafness. Usually performed after 18 weeks, this test uses a needle to retrieve a small sample of blood from the umbilical cord.

However, the American College of Obstetrics and Gynecology ACOG now recommends that all pregnant women be offered screening with the option for invasive diagnostic testing for Down syndrome, regardless of age.

The mean age of the mothers at the time the questionnaire was completed was Being carriers of the genetic translocation for Down syndrome.

Down syndrome

Just over a third Tests such as nuchal translucency ultrasoundamniocentesisor chorionic villus sampling can be done on a fetus during the first few months of pregnancy to check for Down syndrome.There is a need to conduct more research in the mental-health aspects of Down syndrome, but the increased awareness of the mental-health issues bodes very well for the future.

There is a need to conduct more research in the mental-health aspects of Down syndrome, but the increased awareness of the mental-health issues bodes very well for the future. With Down syndrome, the extra chromosome causes delays in the way a child develops, mentally and physically.

Down Syndrome

The physical features and medical problems associated with Down syndrome can vary widely from child to child. The pattern of mental health problems in Down syndrome vary depending on the age and developmental characteristics of the child or adult with Down syndrome as follows. Young and early school age children with limitations in language and communication skills, cognition, and non-verbal problem solving abilities present with increased.

Down syndrome is a genetic disorder and the most common autosomal chromosome abnormality in humans, where extra genetic material from chromosome 21 is transferred to a newly formed embryo.

These extra genes and DNA cause changes in development of the embryo and fetus resulting in physical and mental. The addition of this genetic material alters the normal development of a child with Down syndrome and causes the typical characteristics of the disorder.

There are three different types of Down syndrome: trisomy 21 (nondisjunction), translocation, and mosaicism.
