I'm 57, single, and work full time. My partner was diagnosed in 2001 after my observations of tremor, balance problems and slowness of movement prompted me to urge him to see a doctor. He has been on disability since 2002 and has been holding his own physically, but this year there has been a mental decline that is really scaring me. I cannot quit working but wonder how long it will be before he can't take care of himself, and what will I do then?
