Hello. I need some help for me sister. The other day we were out and about and something happened that only happened one other time. She would seem to forget everything that seemed to happen withing 5 minutes. We would leave a store, and she would forget that we even went in, or even forget that she picked certain things up. We brought this up with her Dr and she said it sounded like a Waking seizure? Has this happened to anyone, and if so, was it followed by a day or so of headaches? Thank you.
