Identical Twins and Alzheimer`s06/17/1999 |
If one identical twin gets Alzheimer`s disease, can the other expect to get it also?
Although the exact figures vary from one study to another, it is clear that an identical twin carries a significantly higher risk for AD if the other twin develops the illness.A well-conducted study of Swedish twin pairs showed a 67% rate of developing AD in the second identical twin, vs. only a 22% rate of AD in the second fraternal twin.
