After 12 years of Alzheimer to my dad(81), now finally time may be coming to be ready for the worst. Today he did not eat food, hard to drink water too. Sleeping 16 hrs a day. Problem in urine pass and long toilet(as always). what really are the very last days symptoms???? In this time of covid 19 its more risk to go to hospital as well. what is tube feeding ? can it work well? I think my dad may need it if he continue not eating for 3 more days.
