I can help her with simple things, but its getting worse. I work full time and have cancer. She doesn't see her decline but her meds are getting messed up. She lives alone. Some rooms of her home don't have power. She does know who is where and who has passed on.
She needs to be where whe can have support and care, but who can do that.
They might tell you to call Adult Protective Services, or they might ring up your neighbor themselves and ask if they can visit.
No one can force her to move elsewhere unless she has been declared incompetent.
Sometimes not taking certain prescription meds properly can result in dementia-like symtoms (eg: thyroid meds, sleeping pills, pain pills, etc).
I'm sorry you are going through cancer... bless you for caring about your neighbor. May you receive healing and peace in your heart!
