"I'd spent four and a half years recovering from stroke-like symptoms without ever having had a stroke but I couldn't speak," revealed Green, who then elaborated on his condition, saying that doctors said he had ulcerative colitis and vertigo, which left him bedridden for months.
"Then these neurological things started happening after the vertigo, and that was — it was four and a half years of my life. I got to the point where I shuffled like I was a 90-year-old man," recalled Green.
"I couldn't speak. I couldn't read. I couldn't write," added the actor.
Burke then asked Green if his illness was related to an accident that he and ex Megan Fox were a part of, but he denied it.
"No, it was dietary," revealed Green, who added that the "press has it all wrong."
"It was all undiagnosed by Western medicine, so I ended up having to finally find a doctor that is much more into, like, kinesiology and Eastern medicine," he continued, noting that he was diagnosed with having "internal inflammation from gluten and dairy."
Green claimed that even doctors at Cedars-Sinai and top neurologists couldn't diagnose the issue.
"I had such brain fog that I reintroduced my best friend of like 25 plus years to my sister who he had also known for 25 plus years," he shared, also adding that reading to his children became difficult.
