This afternoon, my 72 year old wife has had a difficult time putting thoughts together. She had an eye exam this morning and her pupils were dilated. She had a bit of what she calls a visual migrane this afternoon where her vision is somewhat like looking through a kaleidoscope. She looks fine. She can read from a magazine out loud. She can remember middle names of our 4 children. Can play online solitaire. But feels that her comprehension when reading and her ability to put thoughts together is impaired.
