A court document filed by Peter Falk's daughter says the Emmy-winning actor, known for his role on the TV series "Columbo," is suffering from Alzheimer's disease.

Catherine Falk is seeking a court's approval for a conservatorship of her 81-year-old father, who she claims no longer recognizes people. A hearing has been scheduled for late January.

Falk won four Emmys for his starring role in "Columbo." He was also nominated twice for Academy Awards for movie roles in 1959 and 1960.

The petition filed Friday in Los Angeles Superior Court states Falk lives in Beverly Hills with his wife and recently had hip surgery and requires constant care.

A phone message left for Falk's manager was not immediately returned Tuesday.
