It is most likely that you are also at high risk for Alzheimer's disease if both of your grandparents developed it before age 60. Early-onset Alzheimer's disease (before age 60) has been found to have a genetic component, and individuals with a family history of early-onset Alzheimer's disease have a higher risk of developing the disease themselves.
