Parkinson’s disease patients effect on motor learning
Parkinsons disease Learning is defined as, a change in the capability of a person to perform a skill that must be inferred from a relatively permanent improvement in performance as a result of practice of experience (Magill 247). For healthy people to learn a skill, they must show improvement, consistency, stability, persistence, and adaptability. However, for patients with Parkinsons Disease, it is not as simple. Bradykinesia, the slowed ability to initiate and continue movements, is a well-recognized side effect of Parkinsons Disease. In Rostami and Ashayeris study, Effects of motor skill practice on reaction time and learning retention in Parkinsons Disease, they investigated whether or not short-term practice could improve Bradykinesia. Patients with Parkinsons Disease frequently spend more time not only initiating voluntary movements, but also more time carrying out the voluntary movements. Thus, the study gathered 9 patients (7 males and 2 females) with Parkinsons Disease and 9 controls (7 males and 2 females) that were healthy and disease free. The participants were instructed to look at their monitor and to carry out a hand-to-mouth reach when prompted by the random stimulus on the monitor. The researchers used the Kinemetrix 3D Motion Analysis System and three markers that were positioned on the lateral aspect of the wrist, elbow, and shoulder joints to record and analyze the movements in three-dimensional space. Though all of the participants were right-handed, they were all instructed to use their left hand to complete the task because in all of the participants the left arm appeared to be more bradykinetic. The purpose of this study was to see if reaction time coul...

...on that patients with Parkinsons can decrease their reaction time and somewhat increase the speed of the task if they consistently practice. I have seen this first hand and now more clearly understand the importance of patients with Parkinsons practicing tasks on a regular basis. Though patients with Parkinsons may have trouble retrieving how to complete a task from their long term memory, they can practice the task at hand on a regular basis to lessen the effects of the disease when it comes to completing action goals and movements.

Have you or anyone in your family experienced unusual tremors in your head or any part
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.
Bradykinesia is a Greek term that means "slow movement", and it is one of the constituents of Parkinson's disease (2), although it is also associated with other diseases. For patients suffering from Parkinson's disease, it is usually the most tiring and frustrating of the associated conditions. Small muscle movement is one of the first affected areas of the body. Therefore, a common test is to ask the patient to tap her finger. Normal individuals tap their fingers at 4 or 5 Hz, someone afflicted with bradykinesia can usually manage only up to 1 Hz.(3) There is no cure for bradykinesia. Certain surgeries may help decrease the condition. Hope remains for the future while researchers continue to explore different possibilities, examining causes and treatments that will lead to a cure and to more clues about Parkinson's disease, Huntington's disease, and other conditions with which bradykinesia is associated.

Parkinson's is an idiopathic, multifactorial neurodegenerative disease that attacks neurotransmitters in the brain called dopamine. Dopamine is concentrated in a specific area of the brain called the substantia nigra. The neurotransmitter dopamine is a chemical that regulates muscle movement and emotion. Dopamine is responsible for relaying messages between the substantia nigra and other parts of the brain to control body movement. The death of these neurotransmitters affects the central nervous system. The most common symptoms are movement related, including shaking, rigidity, slowness of movement and difficulty with posture. Behavioral problems may arise as the disease progresses. Due to the loss of dopamine, Parkinson's patients will often experience depression and some compulsive behavior. In advanced stages of the disease dementia will sometimes occur. The implications of the disease on the anatomy and physiology of the respiratory and phonatory systems significantly control speech.
Nurse’s play a very important role in the delivery of care to an older person and in complex disease such as Parkinson’s disease, the care provided by a nurse is vital for both the patient and the family of the affected person. The aim of this essay is to understand briefly about Parkinson’s disease and associated issues and the role of the nurse in the management of the condition.
Most signs and symptoms of Parkinson disease correspond to one of three motor deficiencies: bradykinesia, akinesia, tremor, and rigidity. The first two qualities are usually present before tremor, but often attributed to aging by the patient and even the physician, and thus the disease is rarely diagnosed until tremor becomes evident much later. An average of 80% of the nigrostriatal neurons may have already degenerated by the time Parkinsonism is diagnosed, which complicates treatment (Fitzgerald, 130). Bra...

716). Characteristic features of Parkinson's disease include “motor impairment (bradykinesia, rigidity, tremor, gait dysfunction, and postural instability), cognitive impairment (frontal lobe executive dysfunction), and mood disorders” (p. 716). Normally, motor performance depends on the interaction between automatic (unconscious) and volitional (cognitive) control of movement, however those with Parkinson's disease, experience an “early and preferential loss of dopamine in the caudal regions of the basal ganglia (dorsal regions in rodents), which leads to diminished automatic and increased cognitive control of movements that include frontal lobe circuitry” (p. 716). Consequently, those with Parkinson’s disease must sustain a larger cognitive load to execute either motor or cognitive tasks, such as working memory. In the past decade, increasing evidence has accrued for the role of exercise in the improvement of motor performance, which may help both the cognitive and automatic control of movement. Thus, exercise interventions can help those with Parkinson’s disease incorporate goal-based motor skill training, which then helps in engaging circuitry important in motor learning. Individuals with Parkinson's disease become cognitively engaged with the practice and acquiring of movements and skills that were formerly automatic and unconscious. In addition, aerobic exercise is also observed as important for improvement of blood flow and assistance of neuroplasticity in the elderly, which may also play a role in the improvement of behavioral function in those with Parkinson's disease. Petzinger et al. additionally states that exercise also uses goal-based training and aerobic activity which can improve “both cognitive and automatic
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 (PD), known for its degenerative abilities and debilitating affects, is an illness that affects approximately 1 million Americans. The cause of this disease has not been pinpointed, although strides have been made towards a cure. As our elderly population increases, so does our overwhelming need to find a suitable cure that may one day eliminate this disease.

Age, sex, and heredity all play a part in developing the disease. Young people, women, and those without Parkinson’s in their immediate family are less likely to develop the disease. Research has shown that people who do have high risk factors for Parkinson’s may be able to reduce their risk with regular aerobic exercise. However, once a patient has developed Parkinson’s disease their prognosis depends on the severity of their disease. Each patient has different symptoms and different intensities of those symptoms. Those with a more severe case of the disease will have a poor quality of life as opposed to those who are high functioning whom will have a higher quality of
