Mom is 90. She has had no previuos health problems. She got dehydrated and fell 4 weeks ago. In Rehab. They are sending her home on friday, stating that she is able to be home with daytime care only. All meals will be made by her family. She has some good days but on a bad day, headaches and lethargy. We cannot possibly predict anything but without a shunt is she going to get worse?
