Parkinson's Disease
What is Parkinson's Disease?
Parkinson's disease is a progressive disorder of the nervous system that affects movement. It is caused by damage to a part of the brain known as the substantia nigra. This part of the brain is responsible for producing a chemical called dopamine, which helps to control movement. When dopamine levels are too low, the resulting lack of movement control is what causes Parkinson's disease.
What Causes Parkinson's Disease?
The exact cause of Parkinson's disease is still unknown, but there are a few factors that may contribute to its development. Age is a major risk factor, as the disorder usually develops after the age of 50. Genetics also appears to play a role, as certain genetic mutations have been linked to Parkinson's disease. Exposure to environmental toxins, such as pesticides, may also increase the risk of developing the disorder.
Alzheimer's Disease
What is Alzheimer's Disease?
Alzheimer's disease is a progressive, degenerative disorder that affects the brain. It is the most common form of dementia, and is characterized by memory loss, confusion, and changes in behavior. As the disease progresses, it leads to a gradual decline in cognitive function.
What Causes Alzheimer's Disease?
The exact cause of Alzheimer's disease is still unknown, but researchers believe that a combination of genetic, environmental, and lifestyle factors may be involved. Age is one of the biggest risk factors, as the majority of people with Alzheimer's disease are over the age of 65. Genetics may also play a role, as certain genetic mutations have been linked to an increased risk of developing the disorder.
