May I introduce my husband, a PWP, and myself, his caregiver. Lane and I are both retired public school teachers. Several months ago I lurked on this list, and I have a notebook of relevant printouts for our use. When we left on a long trip I dropped the newsgroup. However, we are home again, and I find much that is helpful here. Lane was diagnosed in 1992. The neurologist said he thought we were "about mid-way into this disease" at that time. In September our neurologist said Lane had reached the maximum good with his Parkinson's medications--a blow to us, indeed. He freezes when trying to get his feet moving and lurches dangerously. He falls occasionally, but he is always close to falling when walking. Perhaps some of you can give us some information. Lane suffers from dry mouth. Consequently his teeth are needing a great deal of dental care. We know there is an artificial saliva substance, but we can't remember its name or how we might acquire it. Your information would be helpful. Thanks. And thanks for the caring and giving of information in this group. We are most appreciative.
