Alzheimer's Disease: Causes and Risk Factors |
Causes and risk factors
Reasons not fully understood
Scientists
do not yet fully understand the causes of Alzheimer's disease. It
is likely that the causes include a combination of, and lifestyle factors on
the genetic environment. These factors
affect each person differently.
Research shows that Alzheimer's disease causes changes in the brain years or even decades before the first symptoms appear, so that even people who seem free of the disease today may be at risk. Scientists develop sophisticated tests to help identify who is most likely to develop symptoms of Alzheimer's disease. Ultimately, they hope to prevent or delay dementia in these high-risk individuals.
