A mutation in our genes can also cause Alzheimer's. If a gene on chromosome 21, the chromosome for the production of amyloid protein, mutated, it would cause the increase the production of the protein causing neurotic plaques. There are also other possible mutations on chromosomes 1, 14, 19, and 21 that can cause the disease. Alzheimer's Disease, as of yet, doesn't have a cure.
