Screening for Alzheimer’s Gene Tests the Desire to Know

March 9, 2016

(New York Times) – In the extended Reiswig family, Alzheimer’s disease is not just a random occurrence. It results from a mutated gene that is passed down from parent to child. If you inherit the mutated gene, Alzheimer’s will emerge at around age 50 — with absolute certainty. Your child has a 50-50 chance of suffering the same fate. The revelation came as a shock. And so did the next one: The brothers learned that there is a blood test that can reveal whether one carries the mutated gene. They could decide to know if they had it. Or not.
