Parkinson's disease is a neurological disease. It is serious. It can be treated and managed. Grandma should see a medical neurologist for work-up and treatment.

Yes Parkinson's disease is a progressive neurological disease. However, there are interventions that can help to delay progression. There are physical therapy programs that can help. I would search in your area for physical therapists in your area that specialize in this. If you are in Baltimore, I can help!
