My 92 year old mom just threw a tantrum because I told her she seemed a bit confused today. She said I am throwing it up in her face. Should you discuss things like this with them? My mom normally is pretty sharp. It just seemed odd. I thought she would respond saying she didn't sleep well, or she is upset... Instead she flew into a rage.
The fact that she "flew into a rage" needs watching, if that's not her normal personality. Just stay aware, but give her room to be 92 years old. If rages become the norm, then she may need to be seen for possible dementia.
Take care,
Carol
