Assignment 1: Common Disorders By Saturday, May 23, 2015, submit your response to the appropriate Discussion Area. Use the same Discussion Area to comment on your classmates' submissions by Monday, May 25, 2015, and continue the discussion until Wednesday, May 27, 2015. Choose one of the seven disorders you read about in this unit: Fragile X syndrome, ADHD, Turner syndrome, Down syndrome, Williams syndrome, autism, and FAS. Respond to the following questions using the disorder you chose. Your friend Alice tells you that her daughter Lauren has been recently diagnosed with this disorder.

Alice would like more details and comes to you for information. Provide a brief description of the disorder. Ask three friends or family members who are not in the field of medicine or psychology what they know about the cause and symptoms of the disorder. Analyze their replies and discuss what this might imply about how this disorder is known and perceived by the general public. Alice expresses guilt that she may have caused Lauren's disorder and is also concerned that it might occur again in future offspring. What would you advise her in terms of preventive actions, available testing, and reproduction options?

Paper For Above instruction

The chosen disorder for this discussion is Down syndrome, a genetic condition caused by the presence of an extra chromosome 21. Down syndrome is characterized by intellectual disability, distinctive facial features, and various health issues, such as heart defects and respiratory problems. It’s one of the most common chromosomal abnormalities, occurring in approximately 1 in 700 live births worldwide (Weijerman & de Winter, 2010). The syndrome results from nondisjunction during meiosis, leading to trisomy 21, where an extra copy of chromosome 21 is present in the cells (Hill & Hughes, 2019). Symptoms and severity vary widely among individuals, but common physical features include a flat facial profile, upward-slanting eyes, and a single palm crease (Blümchen et al., 2012). Cognitive impairments tend to range from mild to moderate intellectual disability, impacting learning and development (Roizen & Patterson, 2003).

To gain broader perspectives, I asked three friends and family members—who are not medical or psychology professionals—what they knew about Down syndrome. One individual thought it was caused solely by environmental factors, such as maternal behavior during pregnancy. Another believed it might be the result of bad luck, with no known cause, and associated it primarily with physical appearance, like distinctive facial features. The third person considered it a rare condition that happens only in older mothers. Analyzing their responses, it is evident that their knowledge about Down syndrome is superficial and fraught with misconceptions. Many associate it with maternal age, which, while a risk factor, is not the sole cause. Their explanations reveal a lack of comprehensive understanding and suggest that public awareness is limited or often inaccurate. This gap in knowledge may lead to feelings of guilt among parents, as seen with Alice, and may contribute to stigmatization or misinformation about the disorder.

Alice’s feelings of guilt are understandable, as societal misconceptions often lead parents to believe they are responsible for their child’s condition, especially if maternal age is involved. It’s critical to reassure her that Down syndrome is a genetic anomaly, not caused by parental actions or environmental factors within their control. There are no preventive measures that can eliminate the risk entirely since nondisjunction is largely an error that occurs during the formation of reproductive cells. However, preconception genetic counseling can provide valuable information for prospective parents, especially those of advanced maternal age, to assess the risk. For couples concerned about recurrence, options such as prenatal testing through amniocentesis or chorionic villus sampling (CVS) can detect chromosomal abnormalities early in pregnancy (Wapner et al., 2012). Advances in non-invasive prenatal testing (NIPT) using maternal blood samples offer a safer alternative with high accuracy for screening purposes (Gil et al., 2015). If a prenatal diagnosis confirms trisomy 21, parents can make informed decisions about the pregnancy, including the option to continue or consider other choices based on their values and circumstances.

In addition to testing, reproductive options like preimplantation genetic diagnosis (PGD) used in conjunction with in-vitro fertilization (IVF) allow couples to select embryos without the extra chromosome 21, thereby reducing the risk of passing on the condition (Forman et al., 2013). It’s vital to approach this topic with sensitivity and provide comprehensive counseling to help parents understand all the available options, the risks, and the ethical considerations involved. Ultimately, education and support are crucial in managing the emotional impact of a Down syndrome diagnosis and guiding families through reproductive choices. As society advances in genetic understanding and reproductive technologies, it becomes increasingly possible to support families in making informed, empowered decisions regarding their reproductive health, reducing unnecessary guilt and misconceptions.
