Common misconceptions with Huntington’s disease and Parkinson’s disease often lead to false health assumptions that are based on their similar symptoms. Huntington’s Disease (HD) and Parkinson’s Disease (PD) are neurodegenerative diseases that affect the motor sector of the nervous system. Both diseases affect the basal ganglia that are deep in the nuclei within the brain. While affecting the brain, both Huntington and Parkinson disease starts taking control of sudden movements and controls that are controlled by the brain. The causes of each disease are different but have similar paths that can be confused as both being the same disease. A surplus or absence of hormones is a direct result of the neural cell deterioration within the brain, …show more content…

The gene that is responsible for the mutation that causes Huntington disease is HTT. The HTT gene is the provider in making the protein called (Huntingtin). The protein affects the neurons in the brain. The mutation that is responsible for Huntington’s disease is the Polyglutamine (PolyQ) expansion in the HTT protein. The HTT protein is the Huntingtin protein. When the PolyQ expansion goes into the HTT protein the neurological disorder begins to form. The HTT protein if it is mutated it will not create enough protein which plays an important role in the brains neurons. Although Huntington’s disease does have genes that cause the mutation, the mutation is then transmitted to one of the parents, which will eventually be inherited to the children. The way Huntington’s disease is inherited is because it has an autosomal dominant inheritance gene. The gene can either be inherited from either parent that has a mutant allele. Since Huntington’s Diseases is hereditary, it develops later on in life. Steven Finkbeiner states, “an individual harboring a genetic mutation could appear normal for decades before developing a mid-life neurodegenerative disease (Finkbeiner, 2011).” Since HD is hereditary, researchers do not understand why it develops later in life. The answer to this is that the expansion of the (PolyQ) database that expanded the HTT is insufficient which …show more content…

However, there are some genetic factors that contribute with the development of Parkinson’s Disease, it is not a 100% genetic condition like Huntington’s Disease. The difference between Parkinson’s Disease and Huntington’s Disease, is the levels of Dopamine that Parkinson Disease releases when its chemical levels are unbalanced. This occurs due to the loss of control of the striatum (subcortical part of forebrain), which controls the levels of dopamine that control the movements in our body. Even thought, Parkinson’s disease is a Central Nervous system disorder, daily habits like smoking can also increase the risk of developing Parkinson’s Disease. Steven Finkbeiner quotes, “Both nicotine and caffeine increase striatal dopamine release, …(Finkbeiner, 2011)”, which explains the results of the research done for Nicotine Smokers to Non-Nicotine smokers. High intake levels of caffeine and nicotine increase a high and unbalanced amount of dopamine levels, which is one of the causes of the development of Parkinson’s disease. The results of unbalanced and high levels of dopamine are the loss of dopaminergic neurons in the

Michael J. Fox is an actor and a writer that was diagnosed at the age of 29 with Parkinson’s disease. When he found out he said, “It was the last thing I expected.” He speaks about his disease regularly and started the Michael J. Fox Foundation, whose goal it is to eliminate Parkinson’s disease. “It is the largest nonprofit funder of Parkinson’s Disease drug development in the world.” And because of this foundation, he was able to control his symptoms and side affects enough to go back to acting by finding a drug cocktail (The Biography of Michael J. Fox).

Ataxia Telangiectasia Ataxia Telangiectasia (A-T) is an inherited disorder that affects the nervous system, immune system, and other systems of the body. The disorder usually progresses before the age of 5 and it makes it difficult for coordination and causes delayed development of motor skills like walking, problems with balancing, and using your hands to grab items etc. A person may even have slurred speech, sway when they walk and wobble. These problems can affect a person as they get older and the effects can become worse as the person ages.

Mild Alzheimer’s is the beginning stage of the disease and usually lasts about two to four years. Symptoms of mild Alzheimer’s include less interest and energy, loss of recent memories, mood swings, and problems with language. If a person demonstrates some symptoms of Alzheimer’s, they do not necessarily have the disease because several medical conditions share the same symptoms. The next stage is moderate Alzheimer’s, which lasts about two to ten years. Symptoms of moderate Alzheimer’s include not being able to recognize people, confused speech, wandering, trouble sleeping, time and place confusion, and delusions.

In contrast to the etiology, the epidemiology of PD is well characterized: approximately 1% of Americans over age 65 will develop Parkinson's. The disease shows no predilection for any particular ethnic group, and both genders are affected equally. Although PD can strike younger people, they represent roughly 10% of the estimated 3 million cases of PD in the United

What is Alzheimer 's Disease? Alzheimer 's disease is a serious disease that affects more than five million Americans. This disease doesn 't just affect the person who has it, families are drastically affected too. In many cases, caregivers are needed to insure the person can be safe. Alzheimer 's disease comes with warning signs, and the warning signs that someone you know or love could have Alzheimer 's are, memory loss that disrupts daily life, challenges in planning or solving problems, difficulty completing familiar tasks at home, at work, or at leisure, confusion with time or place, trouble understanding visual image and spatial relationships, new problems with words in speaking or writing, misplacing things and losing the

Huntington’s disease symptoms can be broken down into many different categories such as: Motor, Cognitive, Psychiatric, Metabolic, and others. It also includes three different stages, which can show how the person is responding to the disease and as it progresses the symptoms may worsen and affect the individuals daily life activities and more. Motor Symptoms: • There are two categories in which your motor abilities are affected with Huntington’s disease: Involuntary movements (chorea) and impaired voluntary movements, which is the beginning of limb incoordination and an impaired ability to use your hand. As the symptoms worsen the postural reflexes are affected. As chorea (involuntary movements) decrease and other symptoms such as dystonia,

When an older person considers themselves forgetful, they normally don’t think very much of it. But in reality, it may be something a lot more serious that previously thought. This person may have dementia. Becky Kane was interviewed about her experiences dealing with people who were determined to have dementia. Dementia itself isn’t a disease, but in fact it describes a wide range of symptoms and diseases (“What Is Dementia?” 1).

Parkinson’s disease is known as a chronic progressive movement disorder where the symptoms typically continue to get worst over time. It is cause by neurons in the brain that either are malfunctioning or they die. These neurons produce dopamine which functions as a neurotransmitter that sends signals to other nerve cells in the brain. Neurotransmitters are responsible for movement of the body because they tell the muscles when to move. When cell death or a cell malfunction occurs, this causes a decrease in the amount of dopamine which causes a person to lose control of what one considers normal body movement and function.

Nicotine use causes the release of dopamine, leading to feelings of reward and pleasure. However, the effects of nicotine are short lasting, and often followed by withdrawal symptoms such as cravings and irritability. Over time and with continued use, the number of nicotine receptors in the brain can increase, compounding nicotine cravings. Frequently pairing smoking with another activity can also lead to neurochemical changes that affect how parts of the brain connect with each other, which creates the unconscious associations between certain activities and cravings. Further, a person’s genes play an important role in addiction, with certain genetic variants appearing to influence how heavily a person will smoke, how addicted to nicotine he or she becomes, and the likelihood of relapse after
