May is National Stroke Awareness Month, and free stroke screenings are being offered Friday outside the Foggy Bottom Metro station on the GW Plaza. Physicians and nurses will provide stroke-risk evaluations along with information to help lower stroke risk and save lives. Stroke is the third-leading cause of death in the United States. The free screenings will run from 8 a.m. until 1 p.m. at 900 23rd St. NW. For information, call 888-4GW-DOCS (49-3627). The event is being put on by the George Washington University Hospital, the GWU Medical Faculty Associates and the GW School of Medicine and Health Sciences.
