 A new drug for people with early Alzheimer's disease will soon be available here in the U.S. NPR's Sydney Lupkin has more on the medicine that can slow down the illness. The Food and Drug Administration approved Casunla, an Alzheimer's drug made by Eli Lilly. Casunla isn't a cure, but it slowed patients' cognitive decline in clinical trials. The drug removes clumps of protein in the brain called amyloid plaques that develop in people with Alzheimer's disease. Once they're gone, patients can stop taking the drug.
