Actor and comedian Tim Conway was recently diagnosed with dementia, and on Thursday his lawyer Michael Harris announced Conway is “unable to communicate” and is “suffering from fluid on the brain.”

“He showed no ability or willingness to talk and no apparent sign that he comprehended the nature of the Conservatorship or any of my statements to him,” Harris said, according to People magazine. Conway’s attorney reportedly visited his home on Tuesday.

To make matters even more complicated, Conway’s daughter Kelly and wife Charlene are locked in a heated dispute over the 84-year-old’s medical care. Kelly is pursing a temporary restraining order against Charlene, whom she alleges is attempting to move Conway out of his current treatment facility. Charlene has denied the claim.
