A positive Alzheimer's blood test in someone with no memory problems can create a new kind of patient: a person flagged by a lab result but not actually ill. Neurologist Dr. Gayatri Devi of Park Avenue Neurology in New York and the Zucker School of Medicine explores these "patients-in-waiting" in a Viewpoint published in JAMA on Oct. 19.
Devi opens with a familiar scene. A woman in her 50s, with no symptoms and no family history of the disease, asks for an Alzheimer's blood test because she fears facing decline alone.
