Alzheimer’s disease is a progressive, neurodegenerative illness that affects an individual’s memory, behavior, and thinking. While the exact cause of Alzheimer’s is unknown, researchers have identified three main factors that may contribute to its development: age, genetics, and environmental influences.
Age is a major risk factor for developing Alzheimer’s. As individuals get older, the risk of developing the disease increases significantly. While Alzheimer’s is not a normal part of aging, the likelihood of developing it increases with age.
Genetics is another factor that can contribute to the development of Alzheimer’s. Certain genes can increase an individual’s risk of developing the disease, including the apolipoprotein E (APOE) gene. Having one copy of the APOE4 gene increases an individual’s risk of developing late-onset Alzheimer’s.
Finally, environmental influences can also contribute to the development of Alzheimer’s. Exposure to certain chemicals and toxins, such as aluminum or mercury, can increase an individual’s risk of developing the disease. Additionally, certain lifestyle factors, such as smoking and not exercising regularly, can increase one’s risk of developing Alzheimer’s.
In conclusion, the three main causes of Alzheimer’s are age, genetics, and environmental influences. As research into Alzheimer’s continues, more information on its causes and prevention will become available.
