Down Syndrome and the Models of Disability Eli Lowham University of Wyoming Having a disability is less taboo and increasingly common in a large proportion of the U.S. population today (Smart & Smart‚ 2006). Speech pathologists in today’s continually expanding world often come across a child with a language disorder stemming from a genetic origin. The most common disorder is Down syndrome. Down syndrome occurs in approximately 1 in 700-1000 births and is the most common genetic cause of intellectual

Mutation may be defined as any change occurred in the DNA sequence‚ which changes the gene function regardless of the morphological or physiological results. It is permanent‚ hereditary and ruled by Mendel’s laws. Such chemical changes are constant and occur during the replication stage and they can be quickly fixed; however‚ a mutation may occur if not repaired. They can affect autosomal genes (dominant or recessive) or be linked to sex chromosomes. Mutation can result in several different types

monosomic cell has one missing chromosome (2n - 1) = usually lethal except for one known in humans: Turner’s syndrome (monosomy XO). [pic] The frequency of nondisjunction is quite high in humans‚ but the results are usually so devastating to the growing zygote that miscarriage occurs very early in the pregnancy. If the individual survives‚ he or she usually has a set of symptoms - a syndrome - caused by the abnormal dose of each gene product from that chromosome. [pic] 1. Human disorders due to

Just because they are disabled doesn’t mean they are not a part of the whole or that they cannot possibly make a positive difference in the world. As the author of the article‚ “A Child with Down Syndrome Keeps His Place at the Table” points out that we have made a lot of progress for children with Down syndrome in the United States. Most of that progress he points out is their rights to go to school. They have progressed from just being recognized as needing to be “somewhere special”‚ a place of horrific

who drinks and smokes during pregnancy will have more of a chance of having a person develop Down syndrome. I even thought this. But in my studies on this subject i found that‚ to my surprise‚ it is a genetic disorder. My cousin who had had Down syndrome had it because it was a chromosomal disorder. Not an environmental or self-medicated teratogen played a part on him developing trisomy 21(Down syndrome). On the other hand‚ environmental and self-medicated teratogens played a huge part on his foetal

This disability originates before the age of 18. Intellectual functioning—also called intelligence—refers to general mental capacity‚ such as learning‚ reasoning‚ problem solving‚ and so on.

The case student for this project will be Derrick Shepherd. Derrick’s diagnosis is Down syndrome. Derrick is in 4th grade‚ 10 years old‚ and has an IQ of 39. Derrick can say approximately 25 words‚ all which are hard to understand unless you are familiar with his language. He has hypotonia and fine motor difficulties‚ so he has a hard time manipulating small objects and holding onto pencils‚ pens‚ and other similar objects. Because of his fine motor difficulties‚ his writing is slow and hard

of Citizen and Down Syndrome Family Association discussants argued strongly that IQ does not measure the range of social and general intelligence they most valued” (Koch & Ridgley‚ 2000‚ p. 387). The view-point from this association varies from the majority consensus that valuable intelligence can be measured via an IQ test because they are part of at least a couple small groups that sway their decisions in an alternate fashion.
