These scientists found Alzheimer’s in their genes. Here’s what they did next

People who inherit two copies of a gene variant called APOE4 have a 60% chance of developing Alzheimer’s by age 85.

Only about 2% to 3% of people in the U.S. have this genetic profile, and most of them don’t know it because they’ve never sought genetic testing.

But three scientists are among those who did get tested, and learned that they are in the high-risk group. Now, each is making an effort to protect not only their own brain, but the brains of others with the genotype known as APOE4-4.
