Hi. Today My Husband Was Sitting On The Couch And

Hi. Today my husband was sitting on the couch and began to have tremor like movements staring straight ahead. I said his name and asked if he could hear me . He did not respond. He was staring staring straight ahead and when I looked into his eyes his pupils were dialiated. I called 911 immediately and paramedics came to our home to check him out. BP 120/80 heart rate normal . He came out of it, and felt fine afterwards.
Needless to say it scared me! Was this a seizure? I was afraid he was having a stroke.
