- The multi-talented TV and movie veteran Dick Van Dyke has canceled public appearances planned for next week, his rep tells Entertainment Tonight.

Citing "fatigue and lack of sleep resulting from symptoms of a yet-to-be diagnosed neurological disorder," Van Dyke, 87, will remain in his home in Malibu, with his wife Arlene, and not fly east for a scheduled ceremony at Manhattan's 92nd Street Y, according to the spokesperson.

The Y was planning to present Van Dyke with the institution's first Lifetime Achievement Award for Bettering Humanity through Comedy. Earlier this year, Van Dyke received the Screen Actors Guild's highest honor, its Life Achievement Award.

In addition to starring on TV's top-rated The Dick Van Dyke Show and Diagnosis: Murder, and in the popular 1960s movies Bye Bye Birdie, Mary Poppins and Chitty Chitty Bang Bang (he also starred in Birdie in its original Broadway production), Van Dyke has spent the past 20 years committed to volunteer work at the Midnight Mission, a century-old downtown Los Angeles shelter for the troubled and homeless.
