What is early-onset familial Alzheimer's disease?

ANSWER

Alzheimer's disease strikes early and fairly often in some families. It happens often enough that experts single it out as a separate form of the disease. It’s called early-onset familial Alzheimer's disease.

By studying the DNA of these families, researchers have found that many of them have flaws in related genes on chromosomes 1 and 14. A few of the families share a difference in one gene on chromosome 21.
