Each of my past 2 seizures lasted 4 minutes in total. It has been quite a while since they were within 5 minutes! Whoo hoo!
There are a few stages in a seizure, and one of them is kinda like the 'actual seizure' whereby the seizure activity is most intense & critical (t was not present in the seizure that mum first witnessed when I was around 3, but over the years, it developed and its duration increased too). Prior to starting on medication, it was around 5 min, and prior to acupuncture, the timing of this was around 3 minutes.
