My sister has Alz. and before Christmas her memory had gotten really bad. She was unable to remember anything after 5 seconds. I took her to visit her kids which she has 6 of them. They don't get along so she had to go to each of there houses and was moved around including a grand-daughters. When I picked her up 10 days later she was a mess. She was so drugged she couldn't stay awake and driving her home she started throwing up. She slept for 4 days. I don't know how much was from her drugs they messed up on or her depression. I haven't seen her this bad. Once she finally woke up and I am trying to get her in her regular routine. She now feels every is in the past and doesn't know what is happening to her. Why she is here, she knows she used to live here but thinks it was years ago. She is now very depressed and I'm not sure what to do for her.
