Sometimes when people ask me what they can do to help, I really don't know. Specific instructions don't come easy without specific facts. The best advice I can offer you both is to be patient with each other. Vicky finds comfort in yoga and yoga for caregivers can be equally beneficial.
I found Caregiver Regional Resources International where you complete a short form to find support groups in a selected country, and Italy was on the list. This organization has several tools for the family or professional caregiver, including a newsletter, a magazine, and a discussion forum.
The National MS Society provides sources for caregiver information in America, so maybe the Associazione Italiana Sclerosi Multipla will prove valuable. Vicky's doctor can probably give you suggestions, too.
Good luck, Rudi, and to all caregivers.
