I want to work part-time. Mom needs help but won't accept it. Thinks she can walk the dog & drive. She has MCI & Dr. said no driving. Mom has mobility problems and I believe, early dementia or Alzheimer's. Not diagnosed yet. Refuses to shower or socialize. Says she is ok home alone, but I am worried. Should I let her get her way until something bad happens? Was thinking of life alert or something.
