Children with Down syndrome are usually smaller, and their physical and mental developments are slower, than youngsters who do not have Down syndrome. The majority of children with Down syndrome function in the mild to moderate range of mental retardation. However, some children are not mentally retarded at all; they may function in the borderline to low average range; others may be severely mentally retarded. There is a wide variation in mental abilities and developmental progress in children with Down syndrome. Also, their motor development is slow; and instead of walking by 12 to 14 months as other children do, children with Down syndrome usually learn to walk between 15 to 36 months.
In today’s society more women need to be aware of the disorder that is becoming more common every year. A study shows that there are about 6,000 diagnoses of Down Syndrome each year in the United States("National association for Down syndrome"). One in every 800 babies is born with Down Syndrome (Marsh). This is a rise from the previously reported statistic of 1 in every 733, as it was reported in 2010. Down Syndrome is a common chromosome disorder due to an extra chromosome number 21("PudMedhealth").
This is the additional genetic material alters of the course of development and causes the characteristics that are associated with Down syndrome. A few of common physical traits of the Down syndrome disorders are low muscle tone, small stature, an upward slant to the eyes, and a single deep crease across the center of the palm of your hand. Although each person that is diagnose with Down syndrome may have possess these characteristics to the different degrees. One in every 691 babies in the United States is born with Down syndrome. Which is marking Down syndrome the most common genetic condition of most disorder.
Teenagers also have a higher possibility of having a child born with this disease , they have a percentage of 70-80 percent of having a baby with this disease. Down syndrome. Children with down syndrome often have distinct physical characteristics because of this disease. Most children have a smaller structure than normal children and have short necks, flat noses, and low muscle tone. Children with this syndrome often have to go to speech therapists because of their slowly developing speech delay.
In addition, it affects both males and females, and children of all races (“Progeria 101/FAQ”). Throughout this paper, a brief, yet informative outline will be given about Progeria. The causes, symptoms, diagnosis, treatments, aging, pop culture, and research that is being done will also be discussed. To begin with, Progeria is caused by a single gene mutation in the gene, lamin A (LMNA). Lamin A is responsible for making a protein that is necessary for holding the center of a cell together- the nucleus (Mayo Clinic staff).
The onset of infection usually occurs in the first six months of life. Severe Combined Immunodeficiency is considered to be the most serious of the primary immune disorders. This set of disorders arises because of the inheritance of abnormal genes from one or both parents. The most common form is found in males, and is transmitted via an abnormal X chromosome, provided by the mother. The second most common defect is transmitted to the infant because both parents have contributed an abnormal gene governing the production of a cell enzyme (adenosine deaminase (ADA) or nucleoside phosphorylase) needed for the development of immunity.
As a child with FAS progresses into preschool physical, cognitive and behavioral abnormalities are more noticeable. These children are not the average weight and height compared to the children at the same age level. Cognitive manifestations is another problem with children who have FAS. "Studies have found that preschoolers with FAS generally score in the mentally handicapped to dull normal range of intelligence" (Phelps, 1995, p. 205). Children with FAS usually h ave language delay problems during their preschool years.
Also with the information of the expectant mother’s age and the use of maternal screening, two thirds of Downs Syndrome infants can be identified whilst still in the womb. Research into the origins of Downs Syndrome has been carried out worldwide all with one common question in mind; is the condition genetic, thus making it hereditary? However, research that has been carried out has found, that children born with this condition have the same genetic makeup as a child born without the condition. However, there is one difference and that is a child born with Downs Syndrome, will have an extra chromosome. By having just one chromosome extra is enough to tip the finely tuned balance of the human body and will in turn produce physical and intellectual characteristics that are found in Downs Syndrome.
The cause of Down syndrome is an extra chromosome. In 95 percent of the cases, the child has three instead of two chromosomes on the 21 chromosome. There is a test called amniocentesis that can tell the mother if her child will have Down syndrome. Amniocentesis involves inserting a needle into the amniotic sac to withdraw a small about of the amniotic fluid. The cells in the fluid are then analyzed to see if the child has Down syndrome.
From my understanding of the article these abilities are presented in autistic people with abnormal brain functioning. In addition, most of these brain abnormalities occur in both the left and right hemisphere of the brain. The article stated “most autistic people that present savant skills or abilities are likely to have deficient difficulties in the left hemisphere of the brain, whereas the right hemisphere compensates for parts of the brain that are undamaged. Two neurologists points out that the left hemisphere of the brain normally completes its development later than the right and is therefore subject to prenatal
