Outline and Evaluate biological therapies for the treatment of abnormality Drug therapy is the main treatment for mental disorders and is based on the assumption that chemical imbalance is at the root of the problem. One type of drug is anti-anxiety drugs (e.g.‚ minor tranquillizers called BZs such as Valium. These have a calming effect by inhibiting the nervous system and causing muscles to relax. BZs work by enhancing the action of the chemical messenger GABA‚ which acts to calm brain activity

Jeffery March 13th‚ 2013 In this paper I will be addressing the following questions: What are genes? How do genes of the two parents influence the traits of an offspring? What is Sickle Cell and who is at risk? How abnormalities can contribute to genetic and/or chromosomal disorders such as‚ sickle cell? Before I discuss genes‚ I have to tell what genes are. Genes are working subunits of DNA. DNA is a vast chemical information database that carries the complete set of instructions for making

Trisomy 13 Trisomy 13‚ also known as Patau Syndrome‚ is a chromosomal abnormality where an individual has an extra chromosome 13. Trisomy 13 was first recognized by Patau and his colleagues in 1960 (Matthews‚ 1999). It affects approximately 1 in 12‚000 births and is the least common of the trisomy syndromes‚ after trisomy 18 and trisomy 21 (Down syndrome). An abnormality of the chromosome occurs when mitosis or meiosis does not happen correctly. During mitosis‚ when the cells are dividing

Chromosomal disorders are caused by an abnormality of chromosome number or structure. According to the Encyclopedia Britannica (2012) chromosomal disorders are defined as any syndrome characterized by malformations or malfunctions in any system of the body which are caused by an abnormal chromosome number or structure.

In the complex elaboration of humans‚ even genetic can develop abnormalities that will create chromosomal disorders. “Down syndrome is the most common chromosomal abnormality reaching viability” (Ramalho‚ Brandao‚ Matias‚ & Montenegro‚ 2011). In essence‚ we will review how genetic background plays a powerful role in human outcomes‚ both in normal or abnormal conditions

Late-Term Abortions of Fetuses with Severe Birth Defects Congenital malformations‚ deformations‚ and chromosomal abnormalities are the leading cause of infant mortality in the United States. Depending on the severity of the defect(s) the fetus can be diagnosed as being incompatible with life; a term used when a fetus is nonviable or will never have quality of life. Unfortunately‚ the first trimester ultrasound does not usually reveal birth defects as it is too early in the pregnancy. In the third

This final paper will discuss the ongoing debate of genetic/prenatal testing. Procedures for genetic/prenatal testing have been available since the early 1970’s (Press‚ 2008‚ pp. 73-78). Genetic testing identifies abnormalities or changes in the chromosomes and genes. This type of testing is used to confirm or deny a suspected genetic condition or used to predict a person’s chances of developing or passing on a certain disorder (Grant‚ 2000). Once the woman wants to go ahead with the genetic testing

Chromosomal Disorders 1. Name the condition. Edwards Syndrome (or Trisomy 18) 2. Outline the chromosomal abnormality. Trisomy 18‚ or Edwards syndrome‚ occurs when a person has a third copy of material from chromosome 18 instead of the usual two copies. 3. What chromosomes are involved? Chromosome 18 is the only chromosome involved with this disorder. 4. What does it affect? The majority of children born with Edward ’s syndrome appear both fragile and weak; many are underweight.
