Return to First QuestionsMy grandmother had Alzheimer's disease. Will I develop it as well?
There are two types of Alzheimer's disease. Familial autosomal dominant (FAD) Alzheimer’s disease occurs in less than 5% of all cases of Alzheimer’s disease and has a genetic link. For FAD to occur, the disease needs to be apparent over several generations of one family.
Sporadic Alzheimer's disease is more common (90-95 per cent) and people with this type may or may not have a family history of the disease.
