89 yr old dad with dementia living w me over 2 years. I cannot do it any longer. Not wandering, not mean, can eat, dress and bathe unassisted so far. Cannot find his words often, TV remote a challenge but sometimes doable. Cannot remember dates and time has no meaning. Sleeps through the night ok. Sometimes dreams seem reality until he is awake for a while. Can he still do assisted living? How do you know? Looked at memory care but residents seem to look blank...Dad not quote there yet. Help?
