Thank you for your question.
Your wife needs to be seen by her doctor as soon as possible.
There are several possibilities here.

Go with her to the appointment and tell the doctor what you have observed. She needs to have blood tests and a brain scan to rule out medical diseases. She most likely would need medication as well.
Call her doctor as soon as possible before her symptoms get out of controlled.
