a. Bradykinesia and fast postural reflexes
b. Hyperkinesia and a tremor
c. Loss of appetite and deep tendon reflex damage
d. Bradykinesia and Loss of appetite
Answer: D, this is because when a patient has Parkinson’s, there is a destruction of the dopamine-producing cells. Dopamine stimulates the direct pathway which in return makes you move. If there is a destruction of dopamine cells, then movements will be affected. So, the patient will experience Bradykinesia (slow movements). Also, the autonomic system is affected in a patient with Parkinson’s. The patient may experience digestion problems due to slow digestion. This can lead to a loss of appetite.
A: Not the answer because although Parkinson’s will cause Bradykinesia, it won’t cause faster postural reflexes. When the dopamine cells are destroyed, this will cause a loss of postural reflexes and the patient may have poor balance.
B. Not the answer because although the patient would have a tremor, they would also experience Bradykinesia instead of Hyperkinesia due to the destruction of dopamine cells.
C. Not the answer because although the patient would have a loss of appetite due to autonomic dysfunction, they would not experience deep tendon reflex damage. Instead, this patient would have a loss of postural reflexes due to the lack of dopamine cells.
2. What physiological problem will Alzheimer’s disease cause a patient?
a. Loss of motor coordination due to damage of the cerebellum
b. Loss of memory due to damage of cerebellum
c. Problems with memory due to cerebral cortex
d. Difficulty reading/writing due to cerebral cortex damage

...cause pituitary dysfunction. This explains why the patient may show signs or symptoms of loss of bladder control, poor coordination, memory loss, speech problems, less frequent/no menstrual periods, weakness, and slower movements.
A. Not the answer because although hydrocephalus does cause poor coordination and balance, it happens because there is too much CSF in the brain.
C. Not the answer because although memory loss is a symptom of hydrocephalus, the hypothalamus controls hormone production. The hormones that are produced by the hypothalamus help with temperature, hunger, sleep, thirst, mood, sex, etc. It does not involve memory functioning.
D. Not the answer because although the excess production of CSF can cause speech problems involving difficulty comprehending things or even difficulty speaking, but it doesn’t necessarily cause a total loss of speech.

- Parkinson’s disease is the most common neurological disorder. Two centuries ago, James Parkinson was the first to describe the disease in details. He published a monograph, “An essay on the shaking palsy,” describing a neurological illness consisting of resting tremor and an odd form of progressive motor disability, now known as Parkinson’s disease. Parkinson’s disease is associated with many challenges and complexities. This paper will explain the diagnosis, causes and risk factors, and treatments of the disease and how Parkinson’s disease affects people’s behavior....

- Overall explanation Parkinson’s disease (PD) is a neurodegenerative brain disorder that develops slowly in most of the patients. Most of them can be alive for years after getting Parkinson’ disease. PD occurs because of a low level of dopamine inside the brain and people will find it difficult to move without dopamine. Currently, there is no specific method to cure Parkinson and nobody knows exactly about why it happens. PD will not cause people to die directly, but the condition will become severer with times.The rate of having Parkinson is 1/500 and most people get PD at the age of 50 but some get it earlier....

- Parkinson’s Disease Parkinson’s disease has become front page news as of late. It has caught the attention of many due to its unrestricted and devastating effects. People from all walks of life can suffer from the disease. It has no economic, social, or religious boundaries. Well known celebrities such as Muhammad Ali, Michael J. Fox, Estelle Getty, Billy Graham, Janet Reno, Pope John Paul II, and Johnny Cash, among many others, have fallen victim to this debilitating ailment. Because Parkinson’s disease is “one of the most common neurologic disorders of older adults” (Ignatavicius & Workman, 2016, p.... [tags: Parkinson's disease, Dopamine, Neurology]

It may be described as idiopathic or acquired. It is generally not life threatening, however is incurable. Briefly we will discuss the pathology, etiology, signs and symptoms, current treatment trends and future potential treatment regimens.

Each year 50,000 – 60,000 people are diagnosed with this progressive disease. The CDC stated that Parkinson Disease (PD) is the 14th leading cause of death in the United States and worldwide there are about six million people who suffer from the disease (National Parkinson Foundation, 2015). While there are surgical and non-surgical interventions as well as many effective drugs to treat PD, there is no cure.... [tags: Parkinson's disease, Dopamine, Substantia nigra]

- Environmental triggers. Exposure to certain toxic substances or environmental factors may increase the rate of developing Parkinson 's disease, but the risk is relatively small. For example, in the 1980s, a couple of recreational drug users in California developed Parkinson 's-like symptoms after taking heroin contaminated with a chemical called MPTP. Treatment Currently, there is no exact ways to cure Parkinson’s disease. Fortunately, there is a large number of treatments that aimed to relieve the Parkinson’s symptoms and maintain the normal life of the people who got Parkinson....

- This research depicts the causes, symptoms, diagnosis, and treatment of Parkinson’s disease in older patients. Parkinson 's disease is a chronic disorder that causes a progressive loss of nerve cell function in the part of the brain that controls muscle movement—is an incurable neurological condition with debilitating symptoms. Treatment for younger patients include dopamine agonist drugs that mimic dopamine to stimulate dopamine system in the brain. For older patients, treatment is focused is on providing adequate symptomatic benefit in the near term with as few adverse effects as possible.... [tags: Parkinson's disease, Dopamine, Neurology]

- Parkinson’s disease is the second most common progressive neurodegenerative disease that affects approximately 100, 000 people in Canada (Lewis et al., 2014). Thus, the purpose of this paper is to discuss health promotion for older adults with Parkinson’s disease because the symptoms are more severe and can cause fatality for older adults (Lewis et al., 2014). Firstly, I will define and elaborate health promotion, then I will explain the pathophysiology, typical patient responses and complication of this particular disease....

- Parkinson’s disease is a chronic disorder that affects the nigrostriatal dopaminergic neurons in the area of the brain that is known as the substantia nigra. The disease attacks these nerve cells in the brain causing them to malfunction, and die off. Dopamine is a chemical that controls movement and coordination; it is formulated through the neurons located in the brain. Thus, the amount dopamine being produced by the dying neurons decreases leaving the individual without control over their motor movements.... [tags: Parkinson's disease, Dopamine]

- Parkinson’s Disease is known as one of the most common progressive and chronic neurodegenerative disorders. It belongs to a group of conditions known as movement disorders. Parkinson disease is a component of hypokinetic disorder because it causes a decreased in bodily movement. It affects people who are usually over the age of 50. It can impair an individual motor as well as non-motor function. Some of the primary symptoms of Parkinson’s disease are characterized by tremors or trembling in hands, legs and arms....
