My 83 y/o grandmother suffered a stroke a few days ago. She is extremely vital and active. She still worked, kept a house, travelled and had a better social life than me. She improved in the first days. She recognized us, said a few words, was able to use the weak side, and she even walked yesterday morning. I am really upset this morning though, because last night she seemed to have regressed. In the afternoon she wasn't as engaged or focused. She seemed agitated and confused.
