My mother is 86 and has a autonomic neurological disorder which causes fainting and tremors, otherwise able to take of herself. She asked me to direct her to the best decision but I am afraid she will run out of money if she goes to a nursing home. Home care options seem just as costly and don't provide 24 hour care.
She may find assisted living more in line with her needs.
Does she wear a fall alert system? That would be my 1st line of action, this will ensure that someone is notified immediately in case she falls if she faints.
A fall alert would be a smart safety device, one that doesn't require that she press a button but detects her positional status and alerts for her.
Also make sure she has all her legal ducks in a row (assigning PoA, creating an Advance Care Directive, and a Last Will). Wishing you all the best as you move through this process.
