It's more than memory loss, all learning goes including the lessons learned as infants and toddlers having to do with eating, swallowing, walking, etc. I'm responsible for the care of an 86 year old who is deteroriating more quickly each passing week. In my case we've opted for in-home care, but all the paperwork is signed and filed that no extraordinary measures will be taken to prolong her life.
Hospice is by definition for the dying.
There are different levels of hospice care and you should see what's available in your area. Make sure that no artifical means will be used to maintain your mother should she suffer a stroke, heart attack or become terminal. Discuss options with her doctor and know what the home's policy is. The best you can do is try to do what she would want done. As for not being able to see her in this condition.
