Hello:
The episodes you are describing could be
focal seizures with generalization. They seem to have a
temporal lobe origin. The causes may vary depending on patient age and characteristics, they include stroke, infections, tumors, epilepsy itself (causing temporal
sclerosis) and a a lot more.
If the characteristics of the seizure have changed, you need to look for a complete assessment with a
neurologist. Maybe you will need a new Head CT or MRI, and an electroencephalogram, trying to confirm the diagnosis and identify the cause. Also you will need adjustments in your treatment. If the previous seizures were similar, maybe you may only need the treatment adjustment.
By now, I suggest avoiding
sleep deprivation, fasting, driving and risk activities as swimming. Continue taking your medications and let your neurologist know about the episodes.
I hope this helps, please let me know if you have any doubt before your appointment.
