I’m so sorry about your wife. Parkinson’s is a cruel disease. An in-law of mine recently died of it. It’s present for years before noticeable symptoms occur and diagnosis can be made. It’s very sneaky that way. And, like dementia and most neurological illnesses, progression accelerates with time. It is a truly heartbreaking. It’s also very hard on the caregiver. My heart goes out to you.
Thank you for the kind words!
