Wendy Nelson, whose mother died from Alzheimer’s disease and father suffers from it, becomes emotional when talking about the potential of also getting the disease and how that would affect how she would want the end of her life to play out, during an interview with Reuters at her home in Foxborough, Massachusetts, U.S., March 21, 2023. A genetic test through 23andMe shows that Wendy carries two APOE4 gene variants, and her three daughters each carry one APOE4 gene variant, indicating an increased risk of Alzheimer’s disease.
