Reynolds opened up about his father's battle on "Today" last year, explaining that his dad rarely acknowledged the disease.
"My father really hasn't ever said he has Parkinson's disease," Reynolds said. "He comes from a pretty prideful generation, and he doesn't really talk about it too much. But, he's maybe said it once or twice out loud."
He continued, "I think one of the interesting things about having a family member who's diagnosed with this particular disease, who isn't really engaging in an active fight against it, it kind of galvanized everybody else to seek resources. And for [my family], in a strange way, it's really kind of brought us together."
