Unable to walk or form sentences, Danny Bonaduce was a shell of himself after coming down with a mystery illness earlier this year. He's still at 100%.
The former "Partridge Family" star was first alerted to his health situation after his wife, Amy, noticed his strange speech pattern in May. From there, his symptoms only got worse.

"I couldn't walk at all," he told "Good Morning America" this week. "I couldn't do anything like that. She looked really nervous. And she said, 'You're not saying words, you're not speaking English,' which of course is preposterous to me."
"We call an ambulance and [it] took me to the hospital where I remained for the first five days and remember very little of it," he said.
After his health became more stable, the actor was determined to find out what was wrong with him, but doctors were flummoxed.
"I couldn't walk," he said. "I couldn't keep my balance. I slurred really badly. I was afraid of everything. I was afraid of my stairs for God's sake — I was hoping for a diagnosis but did not get one."
Doctors, however, were able to rule out a stroke.
"There was nothing that said this was gonna happen," he added. "Take time to consider your health and what you're doing. Pay attention."
Although his health remains a mystery, Danny is well enough to return to his Seattle radio show, which he did on Monday, June 27.
"My brain is still a little fuzzy but that's never stopped me — or the people who hire me," he joked on Instagram before returning to the airwaves.
