Huntington 's Disease, Symptoms, Etiology, Diagnosis, And Diagnosis

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.

Huntington's disease is an inherited neurodegenerative disorder. It is passed on to children from one or both parents (though two parents with Huntington's is extraordinarily rare) in an autosomal dominant manner. This is different from autosomal recessive disorder, which requires two altered genes (one from each parent) to inherit the disorder.

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 (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 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.

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

Huntington’s Disease is an inherited disease of the brain where the nerve cells break down over time. Huntington’s disease can also be called HD or Huntington’s Chorea, due to over 90% of patients having Chorea as well as HD. Chorea is an abnormal body movement disorder, which affects people with HD when it comes to muscle spasms, and involuntary movements. HD is a very rare disease, fewer than 200,000 cases in the U.S. per year. If an immediate family member has HD, you have a 1 in 2 (50%) chance of inheriting the disease. After the condition appears, patient usually lives for 15 to 18 years, HD is a guaranteed death. HD can cause cognitive amnesia, memory loss, behavioral issues (irritability, lack of restraint, etc.), psychological problems (delirium, depression, paranoia, etc.), anxiety, apathy, mood swings, and many more.

Huntington 's disease is an inherited neurodegenerative disease that is caused by a mutation on the HTT gene. It typically effects persons in their third to fifth decade of life and can be passed onto their children. Neurons in the brain waste away or degenerate in different areas causing the characterizing symptoms, such as dance-like movements and mental decline. Diagnosis and prognosis can be devastating to both individual and family. However, there are genetic tests that can help to predict the probability of developing symptoms of the disease. There is no cure for this debilitating disease; only symptom control and maximization of comfort can be prescribed until future research finds a cure. This paper will review origins and symptoms, in addition to treatments and future treatments.

Huntington’s Disease is a progressive brain disorder caused by a single defective gene on chromosome 4.

Huntington’s disease (HD) is a fatal genetic neurodegenerative genetic disorder affecting the brain. It results in uncontrolled jerking movements (chorea), cognitive and behavioural changes. HD leads to incapacitation of the patient and ends fatal. However, death rarely results from HD itself. It is typically due to complications of HD. HD was originally called Huntington’s chorea, because of the involuntary movements that looked like jerky dancing. Chorea is the Greek word for dancing. The majority of HD patients start developing the disease around 30 to 40 or even later. If HD onsets before the age of 20, the condition is called juvenile Huntington’s disease. This form of HD has often expresses the symptoms different and progresses faster

Huntington’s Disease is a disease that kills off brain cells in adults. The disease is estimated to actively plague in 30,000 people in the United States, and leaves 150,000 people with a 50% chance of developing Huntington’s (Huntington’s Disease Statistics).

Huntington’s disease is a rare genetic disorder that slowly kills nerve cells. The cause is the HTT gene in the fourth chromosome, being repeated more times than the healthy gene has. Due to the death of nerve cells, you can get dementia, loss of mental abilities and chorea witch is uncontrollable movements in the arms or other parts of the body. Other symptoms include violent outbursts, seizures, and dystonia or muscle problems like tremors. Also in adolescents having no perseverance and giving up right away.

Huntington’s disease is hereditary disorder that is transient as an autosomal dominant gene that occurs at conception per Ignatavicius (2015) pg. 881. In this disease, gamma aminobutyric acid neurotransmitters are destroyed and replaced with glial cells, causing an influx of dopamine. An increase in glutamate also occurs which causes un controllable jerky, rapid movements of the hands, limbs, and face. HD is diagnosed through genetic testing, and signs and symptoms such as choreiform movements and mental status changes leading to dementia per Ignatavicius (2015) pg. 881. Huntington disease consists of three stages; the first stage being the onset of neurologic or psychological symptoms, secondly the increased dependence for care, and finally

Researches about Huntington’s disease (HD) revealed that it is caused by an expanded CAG trinucleotide repeat in HTT, the gene responsible for expressing the protein huntingtin. It was also revealed that the reduced expression of this protein leads to the neurodegenerative effects of the disease. However, the pathophysiology of the disease is still unknown. This paper investigated the pathophysiology of Huntington’s disease.
