Dot Branning actress Brown - Bardon's on-screen wife - spoke about Bardon's physical condition in an interview with TV Times.
"I visit John regularly - his wife Edna has been marvellous," she said. "I feel for him because he can't write, paint or tell his jokes any more. He is such a clever man and he loved performing."
Brown was promoting her new documentary Respect My Elders, which airs as part of BBC One's 'When I'm 65' season on Thursday, July 12 at 9pm.
The 85-year-old is currently on a six-month hiatus from EastEnders to write her autobiography.
