Reynolds believes that the letter brought closure to their relationship, and he is grateful to have sent it. He also wishes he could have been more patient and understanding of his father’s struggles with Parkinson’s disease.

Reynolds’ father suffered from delusions and hallucinations, which are lesser-known symptoms of Parkinson’s disease. He explained that if he had known about these symptoms earlier, he would have handled the situation better.

Before his father’s passing, Reynolds’ oldest daughter, James, was able to meet her grandfather, which brought joy to both Reynolds and his father.

The actor wrote his father, Jim Reynolds, a letter of gratitude about five months before he died after a 20 year battle with Parkinson’s disease in 2015. ‘I know for a fact it meant the world to him,’ he explained (Pictured with parents Tammy and Jim Reynolds in Los Angeles in November 2005

Reynolds sits on the board of the Michael J. Fox foundation and is dedicated to raising awareness about Parkinson’s disease.

He expressed his wish that the resources available today to treat Parkinson’s disease existed during his father’s struggle, as it would have given him hope.
