My 94 year old mother is now in assisted living. The doctor says she has mild cognitive impairment. My therapist thinks she has Sundowners. My mother goes to bed at about 6 or 7pm. About midnight she starts calling me on the phone, about 3 or 4 times a night. She is confused, disoriented, doesn't know what time it is and can't tell time. What should I do? How do I handle this? Should she be moved to a nursing home? Should I ignore her nightly phone calls so I can get some sleep? Please let me know, as I have no family to help me. And I am wondering if the assisted living facility can handle dementia, etc. Thanks.
