Hello, My mother is 63 yrs old. post 2 years of having a cva, she has a touch of dementia, she gets very mad when someone ask her a question about her health. the past few days she has not been herself. she has been having a lot of dizziness, vomiting, loose stool and not been able to get her words out with out getting mad. she holds her head and chest more, but says there is nothing wrong. what do you think
