Recommended: Conclusions of down syndrome

Down syndrome also known as “trisomy 21” is a genetic condition in which a child is born with an extra chromosone which causes certain features and delays in development. In sexual reproduction (meiosis) the new cell will have half of the mothers chromosones 23 and half of the fathers chromosones 23 to make a total of 46 (23 pairs) in the new cell (zygote). In a child with Down Syndrome they will have an extra chromosone 21 making a total of 47 chromosones. There is no specific reason why this extra chromosone is present but the older the mother is when giving birth the more likely that her baby will have Down syndrome. Down Sydrome is named after John Langdon Down, the first person to describe the condition in 1866. He noted that some of his patients had very similar features and had the same intellectual characteristics despite having no connection. Initially he named the condition “mongoloid idiocy” as he believed the patients had features like a mongolian, although this name was not used for long. People disputed the fact as patients had very different features like hair or eye colour and some had blonde hair and pale skin unlike a mongolian. "The number of idiots who have arranged themselves around the Mongolian type is so great and they present such a close resemblance to one another in mental power that I shall describe an idiot member of this racial division selected from the large number who have fallen under my observation. The face is flat and broad and destitute of prominence. The cheeks are roundish and extended laterally. The eyes are obliquely placed and the internal canthi more than normally distanced from one another. The palpebral fissure is very narrow. The tongue is long, thick and much roughened. ... ... middle of paper ... ...ds are met by his parents, who have done an enormous amount of research and made themselves involved in every aspect of his development. It is always important for the parents to be included in the desicions of his medical care as they are the primary care givers of Dylan. Educating them on his health issues such as ASD and making informed decisions on his treatment is crucial. There are meeting on updates of his care including the Occupational therapist, Physio Therapist, speech and language therapist etc. My role is listening to Dylan and his parents needs and take all of their requests into account when he is at school. I also make them aware of everything he learns as he learns it, his teacher is also communicate with his parents. My duty of care to him is to listen to him, allow him to make decisions when possible, praise and encourage him whenever I can.

  • Were Mongolians Uncivilized and Barbaric?

    Despite the fact that Mongolians were prejudiced against other cultures, they were, in fact, not barbaric but rather civilized because of their gender equality of people and how advanced their cities were. In The Book of Ser Marco Polo, Polo tells us how beautiful and well protected the city was like. For instance, the text explains how the city was protected by two great powerful walls surrounding the entire city. Only well advanced and civilized people can do such a thing such as creating an enormous wall. If the Mongolians were barbaric they wouldn’t have even thought of protection.. In Addition, the way the city looked also proved that they were civilized and not barbaric.

Alternatively, one may argue that the scholars who provided negative documentation of the Mongols only saw the destructive side, not the open-minded side of the society who were known for their cultural acceptance. Although these accounts allowed for an adequate idea of the nature of the Mongols, a record from a peasant who was not a member of the upper class in their society, as all reports presented were from historians, scholars, and political leaders. This would allow for a different perspective on the issue and would produce a better understanding of the topic.

    When the word “Mongol” is said I automatically think negative thoughts about uncultured, barbaric people who are horribly cruel and violent. That is only because I have only heard the word used to describe such a person. I have never really registered any initial information I have been taught about the subject pass the point of needing and having to know it. I felt quite incompetent on the subject and once I was given an assignment on the book, Genghis Khan and the Making of the Modern Age, I was very perplexed for two reasons. One I have to read an outside book for a class that already requires a substantial amount of time reading the text, and secondly I have to write a research paper in History. I got over it and read the book, which surprisingly enough interested me a great deal and allow me to see the Moguls for more than just a barbaric group of Neanderthals, but rather a group of purpose driven warriors with a common goal of unity and progression. Jack Weatherford’s work has given me insight on and swayed my opinion of the Mongols.

    ASD individuals may find it hard to communicate and socialize with others around them. However, because each child is unique, they have their own unique abilities and ways of responding to new experiences. Other issues children with ASD have include; anxiety, sleeping problems, and learning disabilities. Those who are diagnosed with ASD or any other disability are usually judged and bullied. In the documentary Violet’s mother says she is afraid of her child being labeled and underestimated because she is diagnosed with autism. A child’s disability can also affect their family members. Family members may have a difficult time understanding and getting to know the autistic child in order to provide for them. They struggle to find interventions such as treatment and therapy for them, the right medical care, and trying learn to cope with all this. At times parents and caregivers can also feel stressed or irritated knowing they have to fulfill all of the child’s needs. Siblings on the other hand, may find it unfair that the autistic child gets the most attention and

    Most cases of Down syndrome are not inherited. When the condition is caused by trisomy 21, the chromosomal abnormality occurs as a random event during the formation of reproductive cells in a parent. The abnormality usually occurs in egg cells, but it occasionally occurs in sperm cells. An error in cell division called nondisjunction results in a reproductive cell with an abnormal number of chromosomes. For example, an egg or sperm cell may gain an extra copy of chromosome 21. If one of these atypical reproductive cells contributes to the genetic makeup of a child, the child will have an extra chromosome 21 in each of the body's cells.

    Down syndrome is a genetic disorder, associated with the presence of an extra chromosome. Downs is characterized by mild to severe mental impairment, weak muscle tone, shorter stature, and a flattened face. Down syndrome is not a very common disease, one in every 691 children are born with Down syndrome. The disability is an illness that people are born with and is not contagious. Most people with Downs have a life expectancy of about 40 or 50 years of age. They only live for that short amount of time because they begin to develop a similar disease to Alzheimer’s. “100% of people with Down syndrome will develop some physiologic signs of Alzheimer’s when they are over 35 years old in the U.S” (Statistics about Down Syndrome). They also die earlier because having Down syndrome increases the risk of leukemia 15-20 times in the US. Therefore most people with Downs will die because of leukemia or heart problems before the age of 50.

    Down syndrome, a genetic disorder, is the most common cause for intellectual disabilities, occurring at an average of one out of every 700 births (CDS, 2006). This disorder is caused by the extra chromosome 21 (also known as Trisomy 21). According to Hassold and Sherman (2002), the probability of giving birth to a child with DS is not linked to any race, ethnicity, socioeconomic status or geographic location. Maternal age seems to be the only etiological factor that may cause DS.

I will be aware that this student is a learner with special needs and I will teach this student at a level in which he/she is comfortable. I will make sure I am aware of everything that I can about this student?s special needs. I will be in a tight contact with the student and his/her parent/guardian so I can be aware that they are working with him/her at home.

    Trisomy 21 or more commonly known as down syndrome is a condition in which an individual has a full or partial extra copy of chromosome 21 (What is Down Syndrome?, 2012). It was first described as a disorder in 1866 by doctor John Langdon Down and it is the most common cause of cognitive impairment (Heyn, 2014). Today there are three known types of down syndrome trisomy 21 or called nondisjunction, translocation, and mosaicism. Regardless of the type of down syndrome a child may have, they all have an extra portion of chromosome 21 present and the cause is still unknown today (What is Down Syndrome?, 2012). With the cause unknown many people have misconceptions or don’t understand what down syndrome is. That is why I chose to research down

    Down syndrome has always been defined as a genetic condition. It is also known as Trisomy 21, and it is the most common genetic cause of intellectual disability. Nelson and Gibbs (2004) said “Trisomy results from sporadic nondisjunction of chromosome 21 leading to three copies of the smallest human chromosome”. Trisomy 21 is the cause of about ninety-five percent of observed Down syndrome. Most of the nondisjunction comes from the maternal gamete while a very small amount of the nondisjunction comes from the paternal gamete. Along with Trisomy 21, there is also translocation. Cross, Gensburg, and Olsen (2003) said that “Approximately 5% of cases are due to translocation resulting in the presence of three copies of the q arm of chromosome 21”.
