It is quite hard to say, Parkinson progresses very differently from person to person and Freddy is quite living a healthy life. I didn't notice any slowing down as per his pad works but I did notice in the face to face with Margarito team that he was shaking a bit. Also, Roach's Parkinson is more or less controlled by experimental medicine, how effective are they? Not sure at all though but it's not the kind of stuff the common of mortals have access to. I also know that there is a lot of very promising treatments about to hit the market quite soon about Parkinson and IMO, it might not bee too late at all for Freddie to benefit from it in the middle run just in time to resume his trainer's career and to not have to call it a day due to the disease.
