Parkinson 's Disease Is A Chronic Progressive Movement Disorder Of The Central Nervous System

James Parkinson first discovered Parkinson's Disease in 1817. Parkinson's Disease is a common neurologic disorder for the elderly. It is a disorder of the brain characterized by shaking and difficulty with walking, movement, and coordination. This disease is associated with damage to a part of the brain that controls muscle movement. Parkinson's Disease is a chronic illness that is still being extensively studied.

Parkinson 's disease is a progressive neurologic degenerative disease of the Central Nervous system. The brain produces Dopamine and Norepinephrine, which are chemicals needed for smooth muscle movement and coordination, heart rate, and blood pressure. Dopamine and Norepinephrine are released by basal ganglions that are produced in a bundle of nerve cells in the brainstem called substantia nigra. In Parkinson 's patients, the substantia nigra are destroyed and neither of the chemicals can be released into the body. (3) The decrease in Norepinephrine causes heart arrhythmia and low blood pressure, causing the person to get dizzy upon standing or tire easily. The lack of Dopamine, the smooth muscle movement and coordination controller is now gone, or significantly decreased, resulting in the first signs of Parkinson’s disease, pill-rolling, a one handed tremor and a decreased appetite.

Parkinson’s disease is a “neurodegenerative disorder of the basal nuclei due to insufficient secretion of the neurotransmitter dopamine” (Marieb & Hoehn, 2013, p. G-17). The cause of Parkinson’s disease is unknown, but many factors play a role in the development of Parkinson’s disease. One factor that has been found in an individual who has Parkinson’s disease causes over activity of targeted dopamine-deprived basal nuclei. This over activity is caused by the breakdown of neurons that release dopamine in the substantia nigra (Marieb & Hoehn, 2013). Another factor that is present in a person who has Parkinson’s disease, is the presence of lewy bodies in the brain stem ("What is lbd?," 2014). Lewy bodies are unusual

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 is caused by the destruction of dopamine-producing nerve cells in the midbrain (Substantia nigra). These nerve cells are used to coordinate smooth and regular body movement. In the absence of these cells, people often experience tremors (involuntary shaking or

Parkinson’s disease is a progressive disorder of the central Nervous system and affects both motor and nonmotor functions. parkinson 's is caused by a chemical imbalance within the brain. The brain produces a neurotransmitter called dopamine in the basal ganglia, which is structures linked to the thalamus in the base of the brain. If the Dopamine, Basal ganglia and Thalamus does not function properly then causes major damage,. A person having less and less dopamine, the individual has less and less ability to regulate their movements, body and emotions. Although there is no current cure available for Parkinson’s disease, the debilitating conditions can be lessoned through education, therapy, and a variety of treatments to improve their quality of life on the National Parkinson Foundation website.

Parkinson’s is a progressive neurodegenerative disease, primarily affecting voluntary, precise, and controlled movement. Parkinson’s occurs when cells in a part of the brain called the substantia nigra die off. These cells are responsible for producing dopamine. With less and less dopamine, a person has less and less ability to regulate their movements, body and emotions. The terms "familial Parkinson's disease" and "sporadic Parkinson's disease" are used to differentiate genetic from truly idiopathic forms of the disease.

Parkinson’s disease is a disorder that progresses over time. It affects your movement through your nervous system; the disorder causes stiffness, and slow movement in your body. Most noticeably started in little “tremors” in your hands it gradually increases over time. Early stages consists little expression in your face or no movement in your arms as you walk. Your speech may also slur, or slow down. Symptoms usually worsen over time.

Parkinson Disease (PD) is a neurodegenerative disease symptomized by tremor, muscular rigidity, and slow imprecise movements. Typically, the disease affects middle-aged and elderly individuals. PD is associated with degeneration of the basal ganglia of the brain causing a deficiency of the neurotransmission of dopamine.

To be honest, Parkinson’s disease scares me; the eventuality of being frozen inside of my own body is terrifying. I have a customer that has shopped with us for at least the past seven years. I can remember when his hands started to shake so badly that he would just hold his coin purse out to me to select his change for him. Now he can’t even remove his own wallet from his back pocket. He will turn around and I pull out his wallet, take out his money or credit card to complete his transaction and then put his wallet back into his back pocket. We don’t talk about it and I try to act like I don’t even notice it, but I do and it’s terrifying.

Parkinson's Disease affects the way the body moves, in the brain, there's an important chemical called Dopamine which controls movements that the body makes and sends signals to the brain to tell the body where to move. Having Parkinson's Disease, the nerve cells in the brain break down to where there isn't enough dopamine and have trouble controlling movements . Figure 1, shows a before and after picture of where in the brain the nerve cells which contain dopamine are located and how the nerve cells become damaged when a person has Parkinson's.

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

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).

Parkinson’s Disease is a very common disorder these days. Over 10 million people live daily with Parkinson worldwide. Parkinson’s Disease was named after an English surgeon James Parkinson who wrote a detailed description essay called Shaking Palsy in 1817. The average age for Parkinson’s Disease is between 45 to 70 years old but you can also have juvenile or young onset as well. Most common symptoms of Parkinson are tremors, bradykinesia or akinesia, or rigidity or stiffness, and balance disorder. Parkinson’s Disease doesn’t have a cure and the cause is unknown it could be a number of things genetics, environmental triggers, age, or gender. Parkinson’s Disease happens because the dopaminergic neuron dies and

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,
