Genetic risk for Alzheimer's disease may extend beyond immediate family

NBC- The genetic risk for Alzheimer's disease may extend beyond immediate family.

Researchers from the University of Utah found having grandparents, aunts, or even cousins with Alzheimer's is also a risk factor.

Their data showed people with three extended family members with Alzheimer's were 43-percent more likely to develop the disease.

But the risk was still highest for those who had parents or siblings with Alzheimer's.
