I am not trying to scare you but a stroke
is rather serious. Do some research and if you think the symptoms
match up force her to see a doctor. whether she believes in them or not this could save her from having a more serious stroke, which could do anything from paralyzing one side of the body or even death. I'm sorry to scare or worry. As I said, I may be wrong, this is only a best guess from a college student, who works with children and took a first aid and cpr course.
