My sister-in-law is acting very strange. Yesterday night her husband said that she was repeating the names of her family members to herself. Today she was at work and a co-employee noticed she was acting strange. A family member called her and she would not believe it was who they said they were. When the paramedics got there she was asking them if she is black. She seems to be having trouble remembering who she is. Her mother, my wife, and her husband are now at the emergency room with her. She does not use drugs and she is a very strong woman. Recently she turned forty. Do you have any idea what might be going on? If you have a few moments to console me I would really appreciate it. I did not go as I did not want to complicate matters--it was agreed that this was for the best.
