No, I don't think it's a stroke. You've just described exactly several episodes Onyx has had over the years. I took her to a neurologist and did MRIs. He found nothing. If it had been a mini-stroke, it would have shown up either there or in the blood work.
He stated that ruling everything else out, they were probably mini seisures. They always seem to occur just as she woke up. (morning, middle of the night, but never after she's been up and awake and active). They lasts just about 30 minutes. Interestingly enough, when she has had anesthesia. like for the MRI, afterwards they would disappear for a while.
She has trouble doing stairs like she doesn't know what they are. THe whole house looks new and foreign to her.
When she was 8 yrs old, she had several episode. We had the MRI, then she was episode free for 2 yrs. She had a few more, then she needed anesthesia for something. They disappeared again. She had a couple last year. Not severe, not many. Nothing yet this year.
She just celebrated her 13th BD last week.
