Review Of Research Paper On Parkinson's Disease Treatment


Attempts to cure or slow down the progression of Parkinson’s disease have largely failed; researchers in this paper maintain this is obviously a direct result of the lack of insight into the pathogenesis of the disease. Parkinson’s disease is the product of the deaths of a number of dopaminergic (dopamine-secreting) neurons in the substantia nigra pars compacta region (SNc) of the brain. But what causes these deaths? In the paper “‘Rejuvenation’ protects neurons in mouse models of Parkinson’s disease,” Chen and researchers find that older neurons in the SNc are unusually reliant on calcium channels and that after blocking these channels, the cells are “rejuvenated” and begin acting like their juvenile counterparts; as a result, these cells become protected from Parkinson’s disease. Their research, thus, points not only to a possible cause of neuronal death in PD but also to a possible means of curing the disease.

Causes / Risk Factors

• Genetics

15-25% of people who have the disease have a parent with the disease. Having a parent with the disease increases a persons risk by 3 fold.

There has not been enough research done on the genetic causes of Parkinson’s Disease to say for a fact that they are directly correlated. When more research is done there may be more strong evidence, but it could go the complete other way as well. The Human Genome project should open many doors with the research of this disease once the funding is sufficient.

• Environmental factors

According to the Parkinson’s Disease Foundation, “Epidemiological research has identified several factors that may be linked to PD, including rural living, well water, herbicide use and exposure to pesticides.” They also state that a narcotic that has been made in labs called MPTP can cause an instant onset of the disease and its symptoms.

• Age

This is due to the fact that they are in the environment longer and their genes are having more time to mutate from sun exposure, unhealthy living styles, and free radicals.

• Sex

Men are at a higher risk than women

• Diet

1. Should be high in green leafy vegetables
2. Eat a balance of other vegetables and fruits
3. Avoid caffeine, tobacco, and sugar

• Yoga

1. Motor skills

• Acupuncture

1. Established correct balance of yin and yang
2. Brings harmony back to the body

• Antioxidants

Used to reduce the negative effects that the environment has on the body

What is Parkinsons?

1. A disease of the brain caused by a lack of the chemical dopamine
2. Dopamine allows the muscles of the body to function properly (i.e. smoothly)
3. The lack of this chemical is caused by the death of the nerve cells that produce dopamine (substantia nigra)
o When dopamine producing cells are reduced by 80%, the physical symptoms of Parkinson’s present themselves

The Neurobiology of Parkinson's Disease Essay

1519 words - 6 pages The Neurobiology of Parkinson's Disease In neuroscience it is assumed that the central nervous system governs and defines all aspects of behavior (Grobstein, 1998). Therefore, the brain, the hub of the central nervous system, is responsible for integrating all sensory and motor patterning. To understand the mechanisms of neurobiology it is often useful to observe the nervous system at the level of the neuron. Integration and communication...

Review of Research Paper on RNA in Mammalian Cells

1142 words - 5 pages Review of Research Paper: Duplexes of 21-nucleotide RNAs mediate RNA interference in cultured mammalian cells Overview The significance of this experiment is that it shows how siRNA suppresses the expression of genes in different mammalian cells. It was known previous to the experiment that dsRNA can trigger apoptosis in cells- this is an automatic defense mechanism that mammalian cells use to protect against the dsRNA possessed by viruses....

Review of Research Paper on Creating Home-Made Stem Cells

3092 words - 12 pages Our paper discusses an important step in the research surrounding stem cells. Pluripotent stem cells are found in the early blastocyst, and can differentiate into different cell types such as neurons, cardiac muscle, or blood cells. As is explained elsewhere on this paper, stem cells are extremely useful and hold amazing medical potential, especially to “grow” specific cells, tissues, and even organs for patients. Controversy mires the...

Effects, Cure, and Causes of Parkinson's Disease

1126 words - 5 pages Today, we encounter wide varieties of problems and diseases. Nowadays, most poeple are only familiar with illnesses that have caused a big impact on society and those that made it to the headlines of newspapers such as cancer, diabetes, malaria, tuberculosis, and many more. Unfortunately, not everyone is given the opportunity to tackle each disease present and therefore, are not aware of the chances of themselves or their loved ones acquiring...

Since the amount of lives this disease affects continues to increase epidemiologists have named Alzheimer's Disease, "The Disease of the Century".In 1906 a German neurologist Alois...

Fetal Neural Transplantation in the Treatment of Parkinson's and Huntington

1522 words - 6 pages Two Diseases, One Hope: Fetal Neural Transplantation in the Treatment of Parkinson's and Huntington's Disease Parkinson's Disease (PD) and Huntington's Disease (HD) are neurodegenerative diseases that are caused by malfunctions within the motor sector of the nervous system. These malfunctions, which are caused either by the surplus (as in HD) or absence (as in PD) of hormones, are a direct result of neural cell deterioration within the...

Paper on Alzheimer's disease

955 words - 4 pages This paper is about Alzheimer's disease, a progressive brain disorder that causes a gradual and irreversible decline in memory, language skills, perception of time and space, and, eventually, the ability to care for oneself (Kalat). These symptoms are affected because this disease involves the parts of the brain that control thought, memory, and language (Kalat). German psychiatrist Alois Alzheimer first described Alzheimer's disease in 1906,...

To think that his "I do not recall" line during the Contra scandal may have been true! The idea of the President of the...

Parkinson’s disease is a progressive, aggressive, disabling brain disorder of the nervous system that affects movement. Parkinson’s is often called a motor system disorder by many doctors. Parkinson’s occurs when the brain cells or neurons decline and cause a deficiency in the chemical brain messenger dopamine. Dopamine is a neurotransmitter that helps the nervous system control muscle activity and a low supply of dopamine causes major symptoms of Parkinson’s. The cause of Parkinson’s disease is unknown but there are several factors that play a roleincluding: Genetic Factors, Environmental Toxins, Oxidative Damage, Accelerated Aging, the presence of Lewy Bodies and Alpha- Synuclein that are found in Lewy Bodies. Genetic factors involves your genes and researchers have identified specific genetic mutations that can cause Parkinson’s disease but it is uncommon except in rare cases with many family members affected by Parkinson’s disease. Also some gene variation appear to increase the risk of Parkinson’s. Environmental toxins or triggers happens when there is exposure to pesticides, carbon monoxide,drug reactions or toxins in food supply which may cause damage. Oxidative damage is a cause that some researchers suggested that free radicals, molecules generated by normal chemical reactions in the body, may damage or kill nerve cells and lead to Parkinson’s disease symptoms. Accelerated aging is a theory that Parkinson’s symptoms occur when the normal, age- related wearing of dopamine-producing neurons speeds up and this reason for aging is not known. Presence of Lewy bodies are clumps of specific substances within the brain cells that are microscopic markers of Parkinson’s, Researchers believe that Lewy bodies hold an important clue to the cause of Parkinson’s. Alpha- Synuclein is found within Lewy bodies in clumped form that cells can’t break down. This is currently an important focus among Parkinson’s disease researchers.
