My mother has Alzheimer’s and lives with my elderly father. She does NOT want to bathe, dress, nor leave the house, how do I help her?

I came across your question when I typed in the same question on goodle. My father is a heart patient and my mother has modeate altzheimer/dementia, who knows what it is. Sometimes she goes for weeks without bathing or washing her hair. She sleeps eighteen to twenty hours of the day, and when she is awake it is hard to get her to dress or leave the house. I am sure you love your parents as I do and this just hurts so much. Maybe someone will respond soon. Good Luck and God Bless!
