You were extremely lucky. I had my first seizure at 73. It was over by the time I got to the emergency room. After various tests it was misdiagnosed as a panic attack. (Understandably because I was the chief caretaker for my husband who had Alzheimer’s.) And later I had another one, which I assumed was another panic attack. Finally the meningioma which was causing the seizures bled and almost killed me. (It was removed during emergency surgery.)

My heart-felt advice from my experience: something in addition to the lack of sleep caused the seizure. Something has changed for you, but for it to be fixed, it has to be found. Be aggressive in finding it.
