This is sad for the woman and the family!  It sounds like she had some sort of dementia and alzheimers which is really scary.  Hopefully she is okay and will be able to be reunited with her family.  It is sad when people get so old that they are deteriorating so much.  I hope my parents don't decline that much as they age but they possibly will.  My grandparents definitely.  anyway, hopefully, they can get better services to help people like this and avoid situations like the one in the article.
