Parkinson 's Disease Is A Motor System Disorder Essay

Parkinson disease (PD), also referred to as Parkinson’s disease and paralysis agitans, is a progressive neurodegenerative disease that is the third most common neurologic disorder of older adults. It is a debilitating disease affecting motor ability and is characterized by four cardinal symptoms: tremor rigidity, bradykinesia or kinesis (slow movement/no movement), and postural instability. Most people have primary, or idiopathic, disease. A few patients have secondary parkinsonian symptoms from conditions such as brain tumors and certain anti-psychotic drugs.

Parkinson’s disease, a type of dementia also known as idiopathic or primary parkinsonism, paralysis agitans, or hypokinetic rigid syndrome/HRS, is on the rise in the U.S. Each year there are over 60,000 new cases in the U.S. alone. With the average person diagnosed with Parkinson’s disease over the age of 65 and America’s rapidly growing elderly population, awareness and concern are becoming significant points of interest for many healthcare professionals.

Parkinson Disease is a brain disorder that affects movement, loss of muscle control and balance. The first symptoms usually include a tremor of the hand, foot, or leg which is often termed as a “shaky palsy.” The disease usually slowly progresses with symptoms getting more intense over many years. Some patients who develop Parkinson’s in their younger years have faster, more rapid, symptom signs. Much quicker than those who develop the disease at an older age. Most patients develop the disease after the age of 60 and as of 2017, there is still no cure for Parkinson’s Disease.

Parkinson 's disease, also known as PD, shaking palsy, and paralysis agitans is an idiopathic neurodegenerative disorder; it rises from an unknown cause and increases in severity over time (Ronken). The disease was named after English physician James Parkinson, who first described it in 1817 (Weiner). PD can be defined as the degeneration of neurons in the substantia nigra, which is the area of the brain that contains dopamine cells and regulates movement. As the degeneration of neurons occurs, the brain loses the ability to generate body movement, which leads to the characteristic symptoms of PD (Weiner). The disease affects approximately 10 million people worldwide and is currently incurable (Weiner). Therefore, scientists have been

Just imagine: your muscles going stiff, tremors running through your limbs constantly and the inability to smile and laugh with your grandchildren. This torment is the everyday experiences of a Parkinson's disease sufferer. Parkinson's disease is a growing concern in our nation, and though we know what the symptoms are, we do not know for sure what causes it, or even how to cure it. Throughout this paper, the definition will be described as well as the symptoms and treatment options.

Parkinson’s disease is a chronic brain disorder that limits mobility in patients that are diagnosed with it. Information about the disease was first published in Western medicine in 175 AD, although evidence of it it has been seen since earlier ancient times. Since then, much has been learned about the disease. In the 1960s, the differences in chemicals in the brains of Parkinson’s disease patients were first identified. Researchers now believe that Parkinson’s is caused by the gradual breakdown of nerve cells in the brain. The degeneration of these cells leads to a lack of dopamine in the brain, which makes nerve functioning more difficult as it is harder for the brain to coordinate muscle movement. The gradual breakdown of neurons causes the symptoms of Parkinson’s to worsen as the patient gets older. Since the 1960s, research on Parkinson’s has been ongoing but not yet conclusive.

Neurodegenerative diseases can be described as a malfunction in the neural mechanical processes that take place within the human brain. This malfunction then causes pathological problems associated to behaviors and movements. They are often complex in that the causes may be unknown, although the symptoms can be impactful and debilitating. There has been links to a genetic component being of causation, but they can also arise from alcoholism, tumors, strokes, toxins, chemicals, and viruses (Lehman, 2014). In this paper I will explore a Neurodegenerative disease called Parkinson’s. I will discuss the risk factors, pathophysiology that will include signs and symptoms, pharmacotherapies, diagnostic methods and monitoring,

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 this paper I am going to talk about Parkinson’s Disease. I will talk about what it is, how it occurs, the symptoms, any cures/treatments, facts, how the disease affects the levels of organization, what levels it affects, how it affects homeostasis, how the disease disrupts homeostasis, and how the body responds.

Parkinson 's disease is a chronic progressive movement disorder of the central nervous system. Early in the course of the disease, the most obvious symptoms are movement-related; these include shaking, rigidity, slowness of movement and difficulty with walking and Parkinson’s like gait (leaning forward, small fast pace steps, shuffling, etc.). Parkinson’s involves the malfunction and death of nerve cells in the brain, entitled neurons. Although damage can be spread about, it primarily affects neurons in an area of the brain called the substantia nigra. The substantia nigra controls voluntary movement, produces the neurotransmitter dopamine, and regulates mood. When taking an in-depth look into the changes a Parkinson’s patient goes through, we see symptoms clearly connecting to that of the substantia nigra malfunctioning. Parkinson’s disease is a chronic and progressive disorder of the brain primarily affecting the motor system, but also affecting thinking and emotion.

In 1817, James Parkinson published his famous treatise: "An Essay on the Shaking Palsy," describing the symptoms which now collectively bear his name. Although many scientists before his time had described various aspects of motor dysfunction (ataxia, paralysis, tremor) Parkinson was the first to collect them into a common syndrome; one which he believed formed a distinctive condition. His sixty-six page essay contained five chapters describing symptoms, differential diagnoses, causality, possible treatments, and prospects for future study. What is most intriguing concerning Parkinson’s analysis (besides its consistent accuracy) is the fact that his clinical observations and inferences were made by watching the

Parkinson’s disease (PD), a degenerative nervous system disorder, is more common every day, yet it is still a mystery on what causes it. More than a million Americans have been diagnosed with PD and every year there are 60,000 new cases. Affecting older people, it is the second most common disorder and the condition is expected to increase as the aging population increases. PD essentially is the loss of dopamine-producing neurons. The increase in research has led to a wide range of possibilities to the causes involving both genetic and environmental factors. There are two different types of symptoms: motor and non-motor.

Parkinson’s disease is a neurodegenerative disorder characterized by motor symptoms or tremors, rigidity, (bradykinesia) or slowness of movement and posture instability. Parkinson’s involves the malfunction and death of vital nerve cells in the brain. This disease primarily affects neurons in area of the brain called substantia nigra. Some of these dying neurons produce dopamine a chemical that sends messages to the part of the brain that controls movement and coordination. The symptoms of Parkinson’s disease usually begin on one side of the body and within time spread to both sides of the body. The primary process that causes Parkinson’s disease signs and symptoms is when dopamine producing nerve cells in the brain die prematurely. Dopamine is one of the main neurotransmitters in the brain. In a healthy brain, ample dopamine is produced so that the brain cells can coordinate smooth and precise muscle movements. However, when dopamine cells are lost, brain cells communicate abnormally with muscles, which can lead to impaired body movement. (Null, 2013, pp. 153-176)

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,

The most common neurodegenerative movement disorder today is Parkinson Disease (Barth et al., 2011), with a prevalence which increases with age – from just 0.01% of the population aged 40 – 44 years and increasing to 1% at age 65, then up to 22% by age 85 and over. The total number of people with PD is expected to continue grow in the coming decades because of the aging society and a range of environmental factors.
