Sullenberger shared the update on his personal website.

NEW YORK -- Capt. Chesley "Sully" Sullenberger, who famously landed a plane on the Hudson River in New York City in 2009, has revealed he was diagnosed with Alzheimer's disease.

"I recently found out I have been diagnosed with Alzheimer's Disease. It is early stage," Sullenberger wrote in part in a statement posted to his website. "For now, this means a name may not come easily to me, I forget a story I have recently told, or I don't sleep as well, but I am in the beginning of this long journey."
