Phil Robertson has been diagnosed with Alzheimer’s disease, among several health problems.

The Duck Dynasty The star’s son Jase Robertson recently detailed his father’s condition, noting that the family is trying to make him “more comfortable” as he battles the deadly brain disorder.

“He’s just not feeling well. He really has problems,” Jase said in an interview with the family Shameless podcast, noting that doctors have also identified “some kind of blood disorder that’s causing all sorts of problems.” It accelerates and causes problems throughout the body.”

Despite the Robertson patriarch’s prognosis, Phil doesn’t let it stop him. “He keeps saying, ‘I’m going to come back to the podcast,'” Jase added.

“But I think, ‘Well, Phil, you can barely walk around without screaming in pain, and your memory ain’t what it used to be.’ He was like, ‘Tell me about it,'” he explained. “So he’s literally incapable – I think he would agree – of just sitting down and having a conversation.”

Jase said the family is “trying to do a lot of things to figure out how they can make him more comfortable and maybe help his memory.” We have a team of doctors and they all agree there is no cure for his illness . And what are you doing? We’re trying to make him a little more comfortable.”

The Duck Commander founder and his family rose to fame through their A&E reality series Duck Dynastywhich ran for eleven seasons from 2012 to 2017.
