The 74-year-old-actor, who starred in the TV series "Evening Shade," reportedly has 24-hour-a-day care at the Hobe Sound estate.
Reynolds has struggled with a host of health issues in recent years, including an addiction to prescription painkillers for which he underwent a month of treatment late last year at the Hanley Center in West Palm Beach, Fla. He also underwent back surgery last summer.
The actor, whose other memorable films include "The Longest Yard" and "Gator" and "Boogie Nights," is also well known for his high-profile relationships - among those Diana Shore, Sally Field and Chris Evert. Reynolds has been married and divorced twice - to actresses Judy Carne and Loni Anderson, with whom he adopted a son, Quinton.
