What is Parkinson's & Alzheimer's disease? Explain each based on their causative agent,means of transsmission,prevention&control.
You expect a long dissertation from a tutor, when a simple web search will provide all the information you need? Puhleeeze!
No but if u know the answer please help me..
Parkinson's disease and Alzheimer's disease are two neurodegenerative disorders that affect the brain. Although they have some similarities, they are distinct conditions with different causative agents, means of transmission, prevention, and control.
1. Parkinson's Disease:
- Causative Agent: Parkinson's disease is caused by the progressive degeneration of nerve cells in the brain, particularly in an area called the substantia nigra. This loss of cells leads to a shortage of a neurotransmitter called dopamine, which affects movement and coordination.
- Means of Transmission: Parkinson's disease is not contagious and cannot be directly transmitted from person to person. It is primarily considered an idiopathic disease, meaning its exact cause is unknown. However, certain genetic and environmental factors may contribute to its development.
- Prevention and Control: As the exact cause of Parkinson's disease is unknown, it is difficult to prevent or control the disease directly. However, some studies have suggested that regular exercise, a healthy diet, and avoiding certain environmental toxins may help reduce the risk of developing Parkinson's disease or slow its progression. Additionally, managing other health conditions, such as high blood pressure and diabetes, may have a positive impact.
2. Alzheimer's Disease:
- Causative Agent: Alzheimer's disease is characterized by the accumulation of abnormal protein structures called plaques and tangles in the brain. These plaques, primarily consisting of a protein called beta-amyloid, disrupt communication between nerve cells and lead to their degeneration.
- Means of Transmission: Alzheimer's disease is not an infectious or contagious disease. It typically develops due to a combination of genetic, lifestyle, and environmental factors. Age is the most significant risk factor, with the majority of cases occurring in individuals over 65 years old.
- Prevention and Control: Currently, there is no known way to prevent or cure Alzheimer's disease. However, several lifestyle choices may help reduce the risk or slow down its progression. These include engaging in regular physical exercise, maintaining a healthy diet (such as the Mediterranean diet), staying mentally and socially active, managing chronic health conditions (like cardiovascular disease and diabetes), and avoiding smoking and excessive alcohol consumption. Staying mentally stimulated through activities like reading, puzzles, and learning new skills may also be beneficial.
In both cases, it's crucial for individuals experiencing any symptoms or concerns related to Parkinson's or Alzheimer's disease to consult with healthcare professionals for accurate diagnosis, treatment, and management.
