Hi there. It's true that Parkinson's can cause many changes. Keep in mind that Parkinson's is usually a slow progressing disease. Some things that help you in your role as caregiver: Encourage your husband to stay as active as possible. Mobility is such a broad topic. If one is persistent, there is almost always a way to get around. Canes, Walking sticks, high and low walkers, scooters, electric chairs. Find and insist he try a Parkinson's exercise group. A physical therapist might be able to help with mobility issues. You might consider joining a Caregiver support group.
