Whats my odds of haveing Alzheimer's?

My grandmother had Alzheimer's, and then my mother appears to have signs of Alzheimer's, whats the probability I'll have it, I'm really worried.

Come to think of it i belive my great grandmother had mental issues before she died.

They can test for this definitively by doing DNA analysis. There are 3 primary genes responsible, passed down from one generation to the next. These genes are present in early-onset (before 65) cases, but not likely to be present in late onset (after age 65) cases. So, if your great grandmother and grandmother were diagnosed in their 80's like most people, there isn't a high familial risk. On the other hand, if they came down with symptoms in their 50's and 60's, it is likely they have the gene. The risk then becomes 50% for each of their children. If your mother has it, then your risk is 50%.

The ingredient, aluminum, has been found in high concentrations in the brains of people with Alzheimer's. Deodorants, aluminum cookware & aluminum foil all contribute to the levels of aluminum in people's brains.
Antiozidant levels have been found to be low in individuals with Alzheimer's.
So, avoid aluminum; take the supplement Spirulina since it helps pull aluminum out of the body, & begin replacing your aluminum dishes with glass or stainless steel.
Begin taking an antioxident formula.
And pay attention to the main ingredient in many of the popular deodorants out there; aluminum chlorylhydrate.
Bad; bad; bad.

probably quite high- sorry

did any of them smoke- apparently smokers of comparable ages are statistically unlikely to get this- not sure it is a good enough reason to start though

Here it is-

Begin your daily mental workout. Studies have shown people who exercise their minds are far less likely to have any kind of brain problems in the golden years. You can't run from heredity though, but you can run at it with a chess board, crossword puzzle,yoga and the big one, memory games! Good Luck.

I asked my doctor that same question. He said that if one parent or one side of the family had it, there is not much risk. If both parents had it then high risk.
