Parkinson's disease is a form of neurological disorder characterized by gradual loss of those neurological functions that governs body movement. The disease is therefore also referred to as movement disorder.
In the early stages of the disease, signs and symptoms are pretty less evident. However, as the disease progresses to more advance stages the following symptoms are prominent :
So far no laboratory tests exist for diagnosing Parkinson's disease. A neurologist will diagnose the disease based on the past medial history of the affected individual followed by thorough analysis of the signs and symptoms. In addition, certain tests may also be required to rule out the possibility of any underlying disease condition. In order to arrive at an appropriate diagnosis, the neurologist will give medications meant for Parkinson's disease to the individual. If the individual benefits from the drug then the diagnosis is confirmed .
Parkinson's disease cannot be cured; the symptoms can be effectively managed and progression of the condition slowed down with appropriate treatment methods. Medications form an important part of treatment regime. In more advanced stages, however surgery may be advised. The following are the various medications prescribed for treating Parkinson's disease.
As the disease progresses, there is gradual loss of neurological functions in the affected individuals. Individuals who do not receive proper treatment often suffer from other secondary debilitating conditions. There is absolute loss of movement making the individual completely bed ridden for rest of the life. However, with introduction of newer generation medications, it has now been possible to effectively manage the symptoms and improve the quality of life .
Parkinson disease occurs due to necrosis of certain nerve cells in the brain which are responsible for producing dopamine. The exact cause that triggers the development of such a type of movement disorder is yet to be known. However, interplay of several factors such as environment and genetic are known to play a role. Genetic factors attribute to 10% cases of Parkinson disease.
Certain genes have been identified to play a major role in causation of Parkinson's disease. Individuals with family history of this disease are at an increased risk of contracting it as they age.
Exposure to certain toxins can predispose an individual to develop Parkinson's disease .
Parkinson disease is the second most common neurological disorder affecting about 7 million individuals across the globe. An estimated 1 million individuals of United States suffer from this neurodegenerative disorder . Individuals aged 60 years and above fall easy prey to this disease. Men are 1.5 times more likely to contract Parkinson's disease, compared to women. Statistics have revealed that a small percentage of individuals (5 – 10%) between the age group of 20 – 50 years have been known to develop this kind of movement disorder .
Parkinson's disease is a result of death of neurons in the brain. These are responsible for producing dopamine. Dopamine is a chemical messenger of the brain that transmits information to control the movements in various parts of the body . The inability of the neurons to produce dopamine causes motor impairment which is the major cause of disability amongst the affected individuals. It has also been found that about 60 – 80% of necrosis of the nerve cells occurs even before the preliminary signs and symptoms of Parkinson's disease occur.
Till date, no methods have been developed to prevent Parkinson's disease. Since the cause is unknown, ways to prevent the onset of the disease also remains a mystery. However, there have been some pieces of evidence suggesting the use of caffeine to help prevent Parkinson's disease.
Individuals over the age of 60 years are the most affected.The disease steadily causes disability greatly interfering with the individual’s ability to carry out daily functions. The preliminary stage of the disease may showcase little or no symptoms. Parkinson's disease cannot be cured. The symptoms can be effectively managed with appropriate medications. In some cases, surgical procedures may be required to improve the symptoms .
Parkinson's disease is a neurodegenerative disorder characterized by loss of neurological functions due to necrosis of the nerve cells in the brain. It is known to be the second most common neurological disorder after Alzheimer disease. Individuals above the age of 60 years are more prone to develop this condition. Parkinson's disease greatly affects the movement ability of the individuals and therefore the disease is also commonly referred to as movement disorder.
The exact factor that leads to development of Parkinson's disease is not clear. However certain genetic factors and exposure to environmental toxins is known to cause this type of neurological disorder.
In the initial stages, Parkinson's disease may show little or no signs at all. As the disease progresses to more advance stages, individuals experience tremors of the hands, fingers and legs. They also have difficulty in walking and their movements slow down to a great extent. Difficulty in talking is evident with slurred speech.
No laboratory tests help in diagnosing the condition. A thorough examination of the signs and symptoms help in confirming Parkinson's disease.
Medications form the basis of the treatment regime. Various classes of drugs are prescribed to keep the symptoms under control. Carbidopa-levodopa is the most effective drug for treating Parkinson's disease. It works by getting converted into dopamine once it reaches the brain.
