Veteran New York news anchor Bill Ritter revealed Friday that he has been diagnosed with early-stage Alzheimer's disease, bringing an end to his more than two-decade run behind the WABC-TV anchor desk.

Ritter, 76, who has anchored the station's 6 p.m. newscast in New York City since 2001, revealed during Friday's Eyewitness News broadcast that it would be his final night anchoring the program.

"After a series of tests, my doctors have told me I have Alzheimer's," Ritter said during the broadcast.
