Dementia And Ethnicity

My grandfather is showing signs of Alzheimer's or Dementia, but the family isn't really sure if it is due to disease or just natural forgetfulness. Are different ethnic groups, specifically asian people, less perceptible to those diseases?

It’s always best to bring an individual who is showing signs of forgetfulness, no matter what degree, to his or her primary doctor and to a neurologist for full testing and diagnosis.  This is not something to be guessing about. The aging process is different for everyone, so it’s important for you to know what you and your grandfather are dealing with. As with most diseases, different cultures and ethnic groups may be affected differently and there is much more research needed so we can find more cures.
