What is Parkinson’s Disease
Many people have probably heard of Parkinson’s disease, as is it is a relatively common disease, however little know what the disease is, and how it affects your body. Parkinson’s disease is a chronic, progressive, and degenerative disease and what it does, is affect the nerve cells in the brain that produce dopamine. Dopamine is an inhibitory neurotransmitter, and is responsible for balancing acetylcholine. Acetylcholine on the other hand is a facilitory neurotransmitter. what that means is obviously there is now an imbalance in the body’s system. The picture on the left shows how transitions of dopamine differs from a person with Parkinson’s compared to a person without. The other picture shows the activity level

It has been researched that it can be heredity, and can have an influence on whether or not, a person will end up with Parkinson's. It is noted that having a close family member with the disease will increase your chances but only a relatively small amount. However, if multiple close relatives have succumbed to the disease, it greatly increases the chances of you getting Parkinson’s as some point in life (Mayo Clinic Staff). It shows a pattern that men are more likely to have this disease than women. Another pattern Parkinson’s seems to show, is that it is common for those in Agriculture. This is because being a farmer specifically, you may be, or are often, around pesticides or herbicides which these directly inhibit dopamine production, which if we remember is the reason for Parkinson’s.(Parkinson’s Disease n.d.) The picture on this page shows a great example, how famers are sometimes not careful and do not take the proper precautions to protect themselves. Yes he is wearing gloves, but he should probably be wearing a mask as not to inhale the …show more content…
These tremors are most often seen in hands and the feet, but can be seen throughout the entire body. Tremors seem to be the worst when a person is a rest, but subside when a person is active, and completely disappear only when a person is sleeping. Parkinson’s people also have a significant amount of rigidity. They have what you call “cogwheel” movement, where they move in segments per say.(Parkinson’s Disease n.d.) They also have a “lead pipe” movement which as you can guess is heavy moments of the limbs. Loss of postural reflexes is another huge give away for Parkinson’s. People with this disease have a hard time standing up right, and are flexed and hunched over at all joints including the back, hips and knees. You can see the picture on the right is of a very severe case of Parkinson’s, he is showing that bent posture in all positions. Back to the lack of dopamine which I explained before was an inhibitory neurotransmitter, a patient with Parkinson’s becomes very unstable and is less able to make compensatory changes to regain their balance. Those diagnosed have a very distinguished gait pattern, which is another dead giveaway. Because they are flexed forward and have a hard time with their center of gravity, they start to shuffle their feet and fall forward, which is called festinating. There is a significant delay between planning to move and actually moving. They now require
Some experts believe this disease is related to the inhalation of pesticides, while others believe it results from the inhalation of chemical elements such as copper, lead, or manganese. It has been linked to heredity. It is believed that 15% of those diagnosed with the disease have a family history of the mutated gene. Scientists believe there are two types of carriers for this gene that determines a diagnosis of Parkinson’s Disease. The first type of carrier guarantees a diagnosis, whereas the second type of carrier only increases the chance of being diagnosed. This theory has yet to be
If you eat unhealthy, fatty foods your whole life, you have a higher risk of developing diabetes, cardiovascular disease, or arteriosclerosis. If you have unprotected sex, you may contract a sexually transmitted disease, such as syphilis, gonorrhea, or HIV/AIDS. But, Parkinson’s doesn’t racially discriminate, nor does it care if someone is wealthy, poor, educated, non-educated, male or female. Anyone can develop Parkinson’s disease. The disease begins in the brain, our most intricate, delicate organ, whose complexity is still not entirely understood, even with today’s technology and experts. The brain intrigues me. I find myself curious about brain
The cause of Parkinson disease, defined by Robert Hauser, who is an author of Medscape, is still unclear. Studies state that there is a combination of environmental and genetic factors for this particular disease. Approximately 10% of cases are currently genetic causes of Parkinson disease. Environmental risk factors such as use of pesticides, living in a rural environment, consumption of well water, exposure to herbicides, and proximity to industrial plants or quarries are commonly associated with the development of Parkinson disease (Hauser, 2016). In addition, according to Hauser, “genetic factors in Parkinson disease appear to be very important when the disease begins at or before age 50 years. In a study of 193 twins, overall concordance for MZ and DZ pairs was similar, but in 16 pairs of twins, in whom Parkinson disease was diagnosed at or before age 50 years, all 4 MZ pairs, but only 2 of 12 DZ pairs, was concordant.The identification of a few families with familial Parkinson disease sparked further interest in the genetics of the disease.
Parkinson Disease’s (PD) is defined as progressive loss of pigmented neurons or cells in the substantia nigra of the brain. These cells manufacture the molecule dopamine, a chemical responsible for regulating purposeful movements. Moreover, when the dopamine level in the brain depletes by 80 percent, the patient will begin experiencing symptoms of PD. Genetics also play a vital role in Parkinson’s development--mutations in the Leucine-Repeat Kinase 2 are its greatest contributors. Furthermore, dopamine levels progressively drop in patients with the disease; therefore, their symptoms gradually become severe as they age. Parkinson’s symptoms are categorized into primary, secondary, motor, and nonmotor. (Fallon & Cataldo, 2013)
Parkinson disease (PD) is a progressive neurodegenerative disorder characterized mainly by physical and psychological disabilities. This disorder was named after James Parkinson, an English physician who first described it as shaking palsy in 1817 (Goetz, Factr, and Weiner, 2002). Jean- Martin Charcot, who was a French neurologist, then progressed and further refined the description of the disease and identified other clinical features of PD (Goetz, Factr, and Weiner, 2002). PD involves the loss of cells that produce the neurotransmitter dopamine in a part of the brain stem called the substansia nigra, which results in several signs and symptoms (Byrd, Marks, and Starr, 2000). It is manifested clinically by tremor,
Dopamine is a brain chemical/Neurotransmitter that work as messenger signal between the Substantia Nigra to the next relay station of the brain, the corpus striatum which helps to produce smooth coordinate movement and also plays a major role to help control muscle’s movement. With Parkinson’s disease, the brain cells that produce dopamine slowly die, which lead to decrease production of Dopamine. The loss of dopamine causes abnormal nerve firing with brain and the cells that control muscle’s movement by sending the messages to the muscles; due to this it becomes really hard to control muscles movement and cause tremors and various other symptoms such as rigidity and difficulty walking and performing daily tasks. Dopamine is not the only neurotransmitter involved in Parkinson’s Disease. Norepinephrine is very relatively close to dopamine and is also involved in Parkinson’s Disease. Individuals with Parkinson’s Disease have loss of nerve ending that produce norepinephrine. Norepinephrine is a major neurotransmitter for sympathetic nervous system, which control many autonomic functions of our body; it causes increase in blood pressure and heart rate. Loss of norepinephrine can help us explain the non-motor symptoms associated with Parkinson’s Disease such as fatigue, decrease in gastric stability and disruption in cognition. Parkinson’s Disease can be hereditary
In Parkinson's disease, shaking involves the arms, hands, rarely head, neck, and mouth; it is prominent when the patient is at rest [on the other hand, in essential or familial tremor, the hands and arms are quiet at rest; only if the patient attempts to perform a task, such as picking up a glass of water or simply writing, then the tremor shows up].
It is unclear if Parkinson's is caused by genetics, environment, or a combination of both.
Parkinson’s is the second most common neurological disease after Alzheimer’s. It is an incurable, chronic progressive disease. Parkinson’s disease is not life threatening, but, it does have a profound effect on the quality of life (Magennis & Corry 2013). Parkinson’s disease is caused by a loss of Dopamine that affects two main brain structures, the substantia nigra pars compacta and basal ganglia deep in the central hemisphere. Low levels of
Parkinson’s disease is a common form of Parkinsonism, affecting as many as one out of every hundred people aged 65 years and over. The disease prevalence increases with age, with
Dopamine is an important chemical messenger that is responsible for relaying nerve signals that initiate movement1. People with Parkinson’s disease lack dopamine-producing cells in the substantia nigra – a region of the brain, which serves as the nerve propagation station. Researchers suggest that these motor impairments are only visible when 80% of these neurons are lost3. Due to this excessive lack in dopamine, many of the bodies’ basic movements are impaired and cognitive processes gradually degrade as PD progresses3. Due to its chronic nature, the 1st symptoms are sometimes masked and only become apparent as the condition worsens; however, the 1st symptom is usually tremors. This can be so mild as a simple twitch in the hand or as severe as a sudden shaking at a random time3. It has also been observed that people with PD tend to have a parkinsonian gait, which is an inclination to lean forward while initiating movement, and they are also prone to stop moving at any moment1. Other common symptoms of PD include rigidity and bradykinesia. People with PD may also experience a slowdown in movement, which is correlated with the fact that their muscles are in a constant state of tension. This so called rigidity may be only impacting certain muscle groups but it is also responsible for a slowdown in
It is caused by the loss of dopamine receptors in the midbrain. There have been some links to genetic mutation and toxic environments, but the evidence overall is inconclusive. Majority of people with Parkinson’s are males over the age of sixty, but there are also cases of juvenile Parkinson’s disease. Parkinson’s disease can cause widespread tremors, stiffness in the neck and limbs, trouble walking, and slowing of movement. There is no standard test to diagnose Parkinson’s, but physicians can run a series of tests based on the information the patient has given them. It can be treated through medication and surgery. Parkinson’s disease is not fatal, but patients will be on medication for the rest of their lives. There are currently no ways to prevent Parkinson’s disease. There are also no cures, but there is extensive research going into stem cells and fetal cell
The cells are dopamine producing cells. The loss of dopamine inside the brain is what causes an individual to have this disease. Although much research has been done on this disease, it is still unclear even today as to why these dopamine producing cells disappear. Also, over many years of research, scientist and doctors have come to the conclusion that Parkinson’s disease is caused by a combination of genetics and one’s own environment. Because people are unique and individualist the symptoms and factors will play a different role in each person. Although many times, people are very similar in their environments as well as their genetics, one person may have Parkinson’s and another person may not have any symptoms or signs of Parkinson’s
Parkinson’s disease is affected by the degeneration of dopaminergic neurons which is responsible to produce dopamine. Dopaminergic neurons have their cell bodies in substantia nigra pars compacta (SNpc) in basal ganglia (O’Sullivan and Schmitz, 2007). Basal ganglia are a collection of interconnected gray matter nuclear masses deep within the brain”. These gray matter masses are caudate, putamen, globus pallidus, subthalamic nucleus and the substantia nigra. Basal ganglia receive its input through striatum (O’Sullivan and Schmitz, 2007).
In the United States there is an estimated 1 million people living with Parkinson’s disease, with the worldwide numbers reaching an estimated 10 million people (American Parkinson’s Disease Association, 2017). Parkinson’s disease, commonly referred to as Parkinson’s, is a neurodegenerative disorder that slowly and progressively deteriorates the central nervous system (Falvo, 2014). This progressive deterioration occurs mostly in the basal ganglia, a structure in the brain composed of grey matter that contributes to complex movement. As a result, the production of dopamine produced by the basal ganglia is reduced. The cause of Parkinson’s is unknown, but both genetic and environmental factors are considered to contribute to its onset. The extreme
