Researchers looked the chromosomes of more than 4,000 Huntington's malady patients and found that DNA repair qualities may focus when the neurological manifestations start. Incompletely subsidized by the National Institutes of Health, the outcomes may give a manual for finding new medications for Huntington's ailment and a guide for examining other neurological issue. Huntington's disease is an acquired neurodegenerative issue brought on by transformations in a quality that encodes a protein called Huntingtin. Indications of the disease normally start in your midlife and incorporate uncontrolled developments, enthusiastic aggravations and, in the long run, dementia. Despite the fact that studies in people and creatures have found pieces of …show more content…
The author states got one person in every 10,000 in the United States gets Huntington's disease. The symptoms are usually begin with minor arm jerks and some facial twitches. Then following these symptoms tremors spread to various parts of the body and then it develops into writhing. People start to lose the ability to learn or improve motor skills. Basically what is going on in the brain is, "the output from the basal ganglia is inhibitory to the thalamus, and damage to the basal ganglia leads to increased activity in motor areas of the Thelma's. This increase produces the involuntary jerking movements." People with Huntington's disease suffer from psychological disorders as well. Sometimes in the early stages of Huntington's disease people are misdiagnose with having schizophrenia. The book also shows a picture of a normal person's brain and a person’s brain with Huntington's disease, the ventricles expanded because of the loss of neurons; therefore the ventricle looks much larger than it actually is, and it is very evident in the picture (Page 255). Last there is a procedure which enables physicians to predict who or who will not get Huntington disease. To determine this, physicians can count the number of consecutive repeats on the combination C-A-G on one gene on chromosome four. In saying this if the number is fewer than thirty-six, the person will not develop Huntington's disease. Although there are several promising drugs currently in various stages of investigation but none of them have been approved for human use, they have only been tested on animals. I personally think that this needs to be something researchers focus on so we can help the people that are suffering from this terrible

Huntington’s Disease is a brain disorder affecting movement, cognition, and emotions (Schoenstadt). It is a genetic disorder generally affecting people in their middle 30s and 40s (Sheth). Worldwide, Huntington’s disease (affects between 3-7 per 100,000 people of European ancestry (Schoenstadt). In the United States alone, 1 in every 30,000 people has Huntington’s disease (Genetic Learning Center). Huntington’s Disease is a multi-faceted disease, with a complex inheritance pattern and a wide range of symptoms. There is also much research being done in the field of Huntington’s disease, because as of 2012, this disease is untreatable. THESIS.
So if one parent has it, and passes the gene on to a child, that child will develop Huntington's disease if they live long enough and each of that child's' children will have a 50% chance of inheriting the gene, and so on and so forth. If you do not have the HD gene you can't pass it on to your children and if your mate doesn't have it then there is no way
The genetic disorder is caused by a mutation in the DNA segment CAG found in chromosome 4 which results nerve cell death. Phenotypic characteristics include gradual motor dysfunction, psychological issues that correlate to degeneration of metal health, and cognitive degeneration. Studies on transgenic mice have allowed a better understanding of the proteins that relate to Huntington’s
Huntington's Disease is a genetic autosomal disorder which effects the brain. It affects about 1 in 20,000 individuals. The symptoms of the disease do not start to occur until after or around 40 years of age. With the onset of the disease the patient starts to gradually deteriorate intellectually, this deterioration also causes involuntary movements. Scientists have only recently found the section of the gene which causes Huntington's disease, and this is allowed them to devise pre-symptomatic tests. However, a cure for the disease is yet to be found.
Huntington’s disease may be irreversible but it can be treated with proper treatment may slow down the effects of the disease and medical attention. In children who have symptoms of Huntington’s disease, some of the symptoms would be a rapid deteriorating in school performance, lack of swift movements, behavior changes etc...
Huntington's Disease (HD) is an autosomal dominant, progressive, neurodegenerative disorder (Walker, 2007 and Harmon, 2007). The gene that causes the disease is located on the fourth chromosome and causes an abnormal number of repeats in the patient's genetic code (Harmon, 2007). Huntington's Disease can have devastating effects on patients' quality of life. The first symptoms of HD generally start between the ages of 30 and 45 and patients are typically asymptomatic prior to this time (Terrenoire, 1992 and Walker, 2007). However, the disease progresses with subtle changes in motor control, personality, and cognition. Patients eventually develop distinct
Huntington's Disease is a devastating and progressive neurological disorder that resu lts primarily from degeneration of nerve cells deep in the center of the brain. The condition was first described by George Huntington, a physician in New York, in 1872. Even then, the physician recognized the all-encompassing factors of the disorder when describing it as, "coming on gradually but surely, increasing by degrees, and often occupying years in its development until the hapless sufferer is but a quivering wreck of his former self".
Huntington’s disease is an autosomal, dominant inherited disorder caused by a polyglutamine expansion at the amino-terminal on the huntingtin protein. It causes a progressive degeneration of spiny nerve cells in the striatum and cortex of the brain, impairing a person’s functional and cognitive abilities. Polyglutamine repeats of 36 are found to be non-threating but sequences containing an additional two or three repeats are associated with Huntington’s disease.
In 2008, the FDA approved tetrabenazine, which is used to help treat chorea. This was the first drug approved to treat symptoms of HD ("Huntington's Disease: Hope Through Research," n.d.). Additionally, the use of antipsychotic drugs are used to help lessen the extremity of involuntary movements and help moderate the individuals temperament ("Huntington's Disease: Hope Through Research," n.d.). In contrast, the use of antipsychotics are not used to help treat dystonia and may actually worsen these symptoms by causing stiffness in movement ("Huntington's Disease: Hope Through Research," n.d.). Many individuals with HD also suffer from depression and may be prescribed fluoxetine, sertraline, or nortriptyline ("Huntington's Disease: Hope Through Research," n.d.). Mood swings and anxiety are controlled with the use of tranquilizers and/or lithium ("Huntington's Disease: Hope Through Research,"
Everyone can relate to the pain of having to watch a grandparent or great-grandparent slowly loose their faculties as they advance into older age. Now, imagine if this seemingly slow digression hit hard and fast at only age thirty. The age where one is finally living alone and independent, with the beginnings of a successful career and the hopes of starting a family and settling down. Huntington’s Disease quickly takes all these dreams and ambitions away, along with control of ones body and mind. The symptoms of Huntington’s, such as involuntary muscle jerks or twitches, had been seen throughout history for many years before being first recognized as an inherited disease in 1872 by Dr. George Huntington (“Hope Through Research). “The hereditary
Huntington's disease is an autosomal dominant disorder, which is found on the # 4 chromosome. George Huntington discovered it in 1872. It mainly has an effect on the nervous system. There are around 210,000 bases between D4S180 and D4S127. The disease itself is found in 2% of people in their childhood, and in 5% of the people they were older then 60. (Miller p 16) In the majority of the affected people the disease is detected between the ages of 35-45. In males the disease begins around the time of their childhood. However, in females it begins later in life. This severe symptom has a tendency for the condition to worsen as it is passed on from generation to generation. Huntington’s disease is paternally
Uncertainty, the cause of stress and worry for people of all ages, is incontrovertibly a dreadful and uncomfortable feeling. Fear of the unknown affects everyone, whether it results from something as inconsequential as a quiz grade or the possibility that an fatal disease exists within your DNA. However, the anxiety caused by uncertainty is infinitesimal compared to the excruciating pain that the certainty of a humiliating and agonizing death can bring, especially to those who have not yet had a chance to live. Huntington’s is a disease that leads inevitably to this death, and there are many people in the world who believe that they may have it. A genetic test is available to confirm the existence of the disease within an individual’s genome,
Named after George Huntington, Huntington’s Disease is a hereditary neurodegenerative disease. It “causes the death of specific neurons in the brain, leading to jerky movements, physical rigidity, and dementia (First).” The mutation was first mapped to chromosome 4 in 1983, becoming the first disease gene to be mapped using DNA polymorphisms (First). In 1993, a group of investigators found the gene that causes Huntington’s Disease. It is caused by a mutation in a gene located on chromosome 4 (Mennitto). The gene contains an abnormally large number of CAG (Mennitto). The gene may lengthen when passed from father to child, but not mother to child (Mennitto).
