After reading other postings..I have another thought that might add some clarity.

A seizure is diagnostically specific. in that in order to be called a seizure, the symptoms must be correlated with rhythmic neuronal firing in the brain. Normally, the electrical activity in the brain is very random. When neurons begin firing in a synchronous fashion that is rhythmic, that is what produces a seizure. Seizure-like symptoms can be caused by other things, like anxiety, panic attacks, substance abuse, etc. It`s reasonable to think that even dissociation could `look` like a seizure. However, without an EEG that captures rhythmic electrical discharges from the brain, events cannot be classified as seizures with any certainty. There are people who have epilepsy.. confirmed seizures, who also have pseudo (or non-epileptic) seizures. Antiepileptic medications will not treat pseudoseizures.

Hope this helps!
