Huntington’s disease is an autosomal dominant, progressive neurodegenerative disorder illness, causing problems such as hindered or jerky limb movement, loss of cognitive function (which can lead to early onset dementia) and emotional problems such as depression (Jones L., Hughes A., 2011). There are a variety of symptoms that are associated with Huntington's disease of which start off with behavioral disturbances such as moodiness, restlessness, paranoia or psychosis before progressing onto more physical changes like head turning limited to only shifting eye position, sporadic and sometimes wild jerking movements of the arms, legs, face, and other body parts as well as slow, uncontrolled movements. Over the years, the sick individual will …show more content…
He called it “On Chorea” and wrote a paper on his findings, later of which were published in the Medical and Surgical Reporter of Philadelphia. (Dennis H. Phillips, 2001) Huntington had originally called this illness a Chorea. Chorea is the latin word for chorus or group of dancers because of the involuntary twitches or body movements that usually accompany those that have been named after it. Hundreds of years ago, it was most likely that those who had Huntington’s disease were often said to be possessed by the devil because of these symptoms, and it was quite likely that at least one of the alleged witches executed during the Salem witch trials in the 1690’s had the illness. Many years before even that, humans didn’t live long enough for the gene to develop too extensively and over the years the symptoms have had longer periods of time to surface. The actual gene that is responsible for this disease was discovered fairly recently in 1992 by a collaborative group of investigators and …show more content…
This gene is translated onto the offspring’s chromosome 4. In a healthy individual, this particular segment of DNA, made up of the building blocks of the DNA, cytosine, adenine, and guanine (CAG), would repeat on average 10 to 28 times, whereas with someone with an active Huntington’s gene would have this section repeated about 36 to 120 times. This creates faulty lines of DNA, which, in turn, makes the brain cells stop functioning properly and eventually will kill off the cell, resulting in the prolonged death of the host. As this gene is passed down through the generations, the amount of replications of this DNA increases slightly, resulting in this disease making itself visible at younger ages throughout the years (David Kanton, 2015). Damage is located very specifically, having a large concentration of sick cells located in the striatum, one small part of the brain. This is the innermost part of the brain and though it may be small in size, the striatum is a very vital section of this organ, as it is involved in many different cognitive

...Huntington’s disease is an inherited disease that causes a breakdown of certain neurons in the brain. Huntington’s disease is a neurodegenerative disorder which causes involuntary movements, emotional disturbance, and cognitive impairment. “Huntington’s disease (HD) is caused by an autosomal dominant pathogenic mutation, resulting in an expanded stretch of 36 or more glutamine residues in the N terminus of the huntingtin (HTT) protein (1)” (Weiss et al., 2012, p.1 ). People who have Huntington’s disease are born with the faulty gene; however, symptoms typically don’t appear until the person reaches middle age. Although in most cases people with HD don’t start to experience symptoms until middle age, some people may start to experience them...

...Huntington's Disease Essay: By Jasmine Mongeon Huntington's disease is an inherited disease characterized by the degeneration of the central nervous system, which ultimately results in abnormal movements and mental deterioration. The genetic abnormality consists of expansion in the trinucleotide repeat CAG in the HD gene on chromosome 4, which codes for the normal protein huntingtin. The HD gene is an autosomal dominant condition which means that only one parent must have the gene in order for a child to inherit HD. Huntington's disease results in abnormal movements and mental deterioration. Each child of an Huntington's disease parent has a 50% chance of getting the Huntington's disease. If the child does not inherit the Huntington's disease...

...Huntington’s disease is a hereditary disorder that progresses throughout life and eventually causes mobility deficits, behavioral symptoms, and dementia. Huntington’s disease can begin at birth, but it mostly begins in midlife. People with this disease have a parent or both parents that are affected by this disease. A child with an affected parent has a fifty percent chance of becoming affected with Huntington’s disease. People that have Huntington’s disease that occurs before the age of twenty is called the juvenile form of Huntington’s disease. If transmission of this disease is equal from both parents, then the onset of the disease can occur at adulthood.

...According to The Huntington's Disease Society of America Huntington's disease is an inherited disorder that results in the progressive loss of both mental facilities and physical control. The symptoms of Huntington's disease can range anywhere from behavioral issues such as mood swings or a total change of personality to loss of coordination or even trouble swallowing. “Huntington's disease is caused by inheriting a mutation in The HTT gene” (Genetics Home Reference). At this point in time there is no cure for Huntington's but there has been some progress in slowing down the disease. “People who are diagnosed with Huntington's disease don’t usually have any signs or symptoms until they are between the ages of thirty to fifty” (HDSA.org). In some very rare cases the symptoms can start in childhood. This type of the disease progresses much faster and the teenager or child who gets it usually only lives ten to fifteen years after being diagnosed. “In the early stages of Huntington's the most common symptoms are poor memory, depression, lack of coordination, and...

...Huntington’s Disease Personal Reference: Down in the Neurology department sat four family members patiently waiting for what seems to be a never-ending check up. As the doctor’s office door peaked open my mother and aunt both walked out with despairing eyes. When I looked up the doctor was handing my mother a best-known neurologist information card. At that moment silence broke out amongst us, as we knew a whole new life experience was on our hands. At age 34 my Aunt Eve was diagnosed with Huntington’s disease. Background/Introduction: Huntington’s disease historical timeline indicates the first made known observation of the disease was by American physician George Huntington in 1872. Examining the symptoms and condition Dr. Huntington wrote a detailed account defining the hidden facts behind the disease. Yet it wasn’t until 1911 when Charles Davenport made major contributions in acknowledging and understanding the sings, symptoms and heritability of HD. The National Library of Medicine defines Huntington’s disease as a genetic degenerative disorder of neurons due to a defect in one part of the DNA. HD is recognized as a hereditary neurological disorder taking a devastating toll slowly diminishing an individual’s ability to speak, walk and reason. Because HD is a programmed genetic disorder its degeneration of nerve cells results in uncontrollable movements, emotional disturbance, and eventually memory loss. Signs: Early onset signs of HD typically trail...

Huntington's: the Anticipation That Kills

...Huntington's: The Anticipation that Kills After doing research on the effects of the disorder Huntington’s disease, it is easy to understand what a disease like Huntington’s will do to an individual way of life. Imagine being thirty years old with a good job, a loving spouse, maybe a couple of kids and an all-around pretty good life. Then imagine one day your boss writes you up and sends you home because he/she suspects you of being intoxicated. A person in this situation could, in months and years to come, learn from a simple blood test that he/she is the victim of a genetic disorder called Huntington’s disease. The ramifications of this illness are endless and affect not only the individual with the disorder but entire families and communities as well. At this time there is no cure or even any significantly effective treatment. However, as with many genetic disorders, research is being done in in this day in age that may promise to one day lead us to such treatment or cure. Huntington’s disease is a neurodegenerative or genetic disorder that affects muscle coordination and some cognitive functions, typically becoming noticeable in middle age. It is much more common in people of Western Europe descent than in those from Asia or Africa. The disease is caused by dominant mutation on either of the two copies of a specific gene, located on chromosome 4. The Huntington gene normally provides the genetic code for a protein that is also called Huntingtin. The mutation of the Huntingtin...

Huntingtons Disease

...INTRODUCTION Many people are blessed to have lived a long, healthy life in a world full of detrimental and deadly diseases. However, not everyone can say the last years of his or her life were even remotely close to healthy. Losing someone you love and care about to natural causes is sad enough as it is. Losing someone to a disease that progressively incapacitates your mental and physical capabilities is something entirely different. An example of such a malignant disorder is Huntington’s Disease, an inherited, degenerative brain disorder that is now diagnosed in 1 out of every 10,000 Americans. Huntington’s Disease Society of America is a voluntary, non-profit health organization dedicated to facilitate the lives of those who have inherited the disease by promoting and supporting scientific and medical research in hopes of developing a treatment or cure. The purpose of this report is to inform the community about the value and importance of the HDSA’s mission and goals and the impact it will have on the victims of this destructive brain disorder. What is Huntington’s Disease? Huntington’s Disease as defined by the Huntington’s Disease Society of America is “a devastating, hereditary, degenerative brain disorder…[that] slowly diminishes the affected individual's ability to walk, talk and reason.” Essentially, the victim loses capability of all motor skills and causes involuntary muscle movements, leaving them fully dependent of another person. Involuntary muscle movements...

The focus will touch on several different topics associated with pre-emptive testing, pregnancy, educational barriers, strengths, signs and symptoms related to the potential of having an aneuploidy fetus. Also, the importance of time sensitive decisions during pregnancy, social support for potential results, financial resources and hardship related to testing. Additionally, the potential for impaired early on-set compromised cognitive functioning linked to Huntington’s disease. Finally, incorporating the expanded role of the professional nursing scope, practice, and ethical dilemmas associated with Huntington’s disease. Chorea a Brief History Huntington-Chorea was identified in 1872 as a rare inherited disorder secondary to “Chorea” jerky uncontrolled movements (Mandal, 2014). Chorea is Greek in origin and defined as “dancing in unison” (Merck Manual, 2015). 1872 the jerky movements were thought to be divine intervention or demon possession that required a type of exorcism to expel (Jumreornvong, 2015). Additionally, with the evolution of genetics in 1983 according to the US-Venezuela Huntington Disease Collaborative Research Project an approximate location of the gene was identified (Mandal, 2014). Likewise, in 1993 the precise...

Dementia affects a person’s memory, judgment, behavior, thinking, and language. Dementia includes Alzheimer’s disease (AD) and tends to increase the most from the age of 65. Various references and literature in reference to dementia indicate that the number of patients with dementia will increase significantly as society ages, especially within the next three decades. Dementia causes significant family issues and can become a financial burden on patients and their family members. These burdens impair the ability of a person to function independently and also have a tremendous impact on his or her relationships and quality of life.

Ethical Health Care Issues

...National Institute Health accomplished mapping of 32,000 genes of the human genome. Gene mapping was a significant research that enabled researchers to focus on gene specific diseases and birth defects. More than 1000 research projects started inward voyage discovery of human kind rather outward exploration of the planets. Clinical research involving human beings have greater potential for risk of misusing the technology. Potential for misusing the genetic research and fear of unknown long term effects on the successive generations have sparked bioethics debates. Like abortion, gene mapping is a very controversial subject and both sides have strong views. For example, should a woman abort the pregnancy based on the abnormal genetic screening results? Genetic technology provides an enormous power within our grips and with this enormous power comes following the ethical standards. Ethical standards should be followed involving human subjects. Genetic screening standards should align with four ethical principles of: • Respect for the human autonomy, dignity, and obtaining informed consent • Genetic screening should cause the minimal amount of harm to the subject • Provides maximum benefit to the subject • Genetic screening should be available to all the patients of a certain population considered high risk for a certain disease or condition Purpose of this paper is to discuss the correlation between genetic screening, four ethical principles, and possibility of integrating ethical...
