 The FDA has approved Eli Lilly's Alzheimer's drug, Denonimab, for adults in early stages of the disease. The treatment will be sold under the brand Kisunla. Alzheimer's is the fifth leading cause of death for adults over 65. The Lincoln Memorial steps will be closed tomorrow during the fireworks display at the National Mall in Washington. Officials attributed the change to safety concerns stemming from ongoing construction in the area. The memorial will reopen on Friday.
