Epileptic seizures are caused by an abnormal, excessive electric discharges from brain cells that is secondary to a variety of causes.
Pseudo-seizures on the other hand are thought to be caused by many different mechanisms although the exact cause is perhaps not well defined.
Since the causation is believed to be different, a person could have both the types. Pseudo-seizures are better managed by a Psychiatrist/Psychologist and in collaboration with a Neurologist if the two types of seizures co-exist.
You need to contact a Psychiatrist/Psychologist for further details about pseudo-seizures.
