The 55-year-old actor was diagnosed with the disease and was was told he would be "pretty much disabled" by now, reported Female First.
"I was diagnosed 25 years ago, and I was only supposed to work for another 10 years. I was supposed to be pretty much disabled by now. I'm far from it. This is as bad as I get, and I can still go to the store and go marketing," Fox said.
The actor said he still has balance issues from time to time, but it hasn't stopped him working.
