My 81 yr old mother is still residing at her home with my 88 yr old father. My father has Demetia and Parkinson's disease and my mother chooses to remain at home without any assistance from anyone but me. I help the best I can, however, I work over 60 hrs a week. My father is consistently falling due to his Parkinson's. Moreover, his Demetia seems to be worstening and fears the company of guests, including family. What can I do to help my mother more effectively. I feel like my mom is going through depression while dealing with her heart problems.
