Huntington 's Disease : A Progressive Brain Disorder Caused By A Defective Gene

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

Huntington’s disease destroys the organs that carry the functions of the central nervous system. Kalat (2013) states, “Huntington disease (also known as Huntington disease or Huntington’s Chorea) is a severe neurological disorder that strikes about 1 person in 10,000 in the United States” (A.B. Young, 1995, p. 258).Individual’s develop the symptoms in their middle age, but even if it is a rare disorders juveniles as well as children before the age of ten can develop the disease. Huntington’s disease is hereditary disease that is passed on from a parent. Huntington’s disease is of the lack of the chromosome 4, if one of the parents carries the gene, they can pass that gene to their

At present, there is no cure for the disease, but dynamic progress has been made as researchers explore this illness. HD is inherited as an autosomal dominant condition. In March 1993, scientists realized that HD is caused by a mutation in a gene located on chromosome 4. This gene has a unique genetic sequence for CAG (cytosine-adenine-guanine) and codes for the amino acid glutamine, a building block for the huntingtin pr otein. Normal individuals have this sequence duplicated from 11 to 40 times in their genetic coding without having symptoms of HD. However, individuals with the disease have from 40 up to 100 repeated CAG segments. Juvenile Huntington's Disease occurs wit h 60 or more repeats, linking the longer chains of CAG sequences to earlier and more aggressive onset of the disease.

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 (HD) is a disability that will continue to get worse and worse over time. The lifespan for someone living with HD is 10 to 25 years after they are diagnosed and showing symptoms, which is usually around the ages of 30 to 50 ("What Is Huntington's Disease," 2017). These symptoms begin at different times and depend on the individual. Overtime, the person affected will begin to lose their ability to walk, talk, and eat over the course of these 10 to 25 years resulting in the need for 24 hour care.

Huntington’s disease is caused by a mutation in the gene for a protein called Huntingtin. The genetic mutation results in the building blocks of DNA (cytosine, adenine, and guanine) to be replicated many more times than in an average individual. As a result, Huntington’s disease breaks down brain cells, or neurons, specifically located in the primary motor cortex regions of the brain, but can effect other brain areas

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

The basal ganglia is comprised of the caudate and the putamen (together these form the striatum), the globus pallidus (internal and external), substantia nigra and the subthalamic nucleus. These components work together in order to coordinate the motor movement of the body. The basal ganglia works with the motor cortex of the brain to execute these motor movements. In the direct pathway signals are transmitted through the basal ganglia (from the striatum to the internal globus pallidus) to the thalamus which then sends it to the motor cortex. Signals that go through the indirect passage take a much more complicated route. First the striatum is excited and the signal continues on to the external globus. The external globus then inhibits the subthalamic nuclei which in turn excites the internal globus. The internal globus then inhibits the thalamus which ultimately excites the motor cortex. When a person has Huntington’s chores neurons in the basal ganglia start to experience cell death, the path to the motor cortex becomes disrupted. When neurons begin to die off the less and less neurotransmitters are released at the damaged part of the pathway. In the direct pathway Huntington’s disrupts the signal from the striatum to the internal globus. This causes a net increase in the inhibition of the thalamus. The more the inhibited the thalamus is, the

The next disease being discussed, Huntington’s Disease, is a hereditary progressive neurodegenerative disorder that can affect the psyche, emotions, and behavior. However, it is most commonly known for the loss of cognitive functioning as well as motor disturbances (Leffler, 2011). Usually the initial signs of Huntington’s Disease starts with jerky movements that can affect various parts of the body (face, arms, legs, etc.) as well as the gradual beginnings of dementia; the memory is usually impaired. There also may be disorientation, or disillusioned ideas of time, place or identity, as well as personality changes and possible increased agitation. Common neurobehavioral changes include: a tendency to blame others for one’s faults, suspiciousness, impulsiveness, constant complaining, lack of self-control, and lack of

Huntington’s Disease is a disorder in the brain that has an impact on the way people talk, think, and move. The disease kills off cells in the part of the brain that controls movements, emotions, and cognitive ability, which is called the basal ganglia. The brain cells of people with Huntington’s Disease build up lots of protein that eventually turn toxic, and cause the cells to die over time. People with this disease can lose up to 25% of their brain cells before they die!

Huntington’s disease is a genetic disease that slowly deteriorates the brain cells. This has a negative impact on both the everyday physical, and cognitive activities of the individual. They begin to lose their fine motor skills, as well as their speaking, processing skills, and emotional control.

Huntington's disease is a neurodegenerative hereditary condition which causes problems in muscle coordination, behavioral symptoms and leads mental deterioration (Hammond and Tatum 2010). Symptom varies among persons of same family. The most punctual side effects are frequently unpretentious issues with state of mind or insight.

Huntington’s disease (HD) is a neurodegenerative disease that affects roughly 10 individuals per 100,000 (Nopoulus, 2016). This disorder is normally associated with symptoms including motor impairment, namely slowed movements and random muscle contractions, as well as depression and cognitive dysfunction. However, another prominent symptom that has yet to be mentioned until recently is sleep disturbance and alteration of normal circadian rhythms. It is estimated that 60-90% of HD patients have sleep issues and that nearly 60% see those issues as being factors in their overall problems (Goodman et al., 2010). Despite the minimal volume of studies, the overwhelming proportion of HD patients who are afflicted with circadian dysfunction and

HD is a rare, progressive neurodegenerative disease which usually manifests itself between 30 and 45 years of age . It's characterised by a loss of motor control, jerky movements, psychiatric symptoms, dementia, altered personality and a decline in cognitive function. As the disease is adult onset, many people have already had children before they are diagnosed and have passed the mutant gene onto the next generation. In 1983, a genetic marker linked to HD was found on Chromosome 4, making it the first genetic disease to be mapped using DNA polymorphisms. However, the gene was not finally isolated until 1993
