Epileptic seizures and pseudoseizures are distinguishable both by their nature and symptoms, but the diagnosis can be difficult. Epileptic seizures are caused by a change in how the brain cells send electrical signals to each other, while pseudoseizures are triggered by a conscious or unconscious desire for more care and attention. Thus, measuring brain activity with an EEG and video telemetry is important for distinguishing epileptic and pseudoseizures. Also, pseudoseizures often lack the exhaustion, confusion, and nausea that is associated with epileptic seizures. Psychogenic seizures can occur in people who also experience epileptic seizures.
Epilepsy is a chronic condition of recurrent unprovoked seizures.
There are many types of non-epileptic seizures. Non-epileptic seizures differ from epileptic seizures in that there is usually no evidence of abnormal electrical activity in the brain after the seizure, and they do not occur repeatedly. The nature of the seizures varies depending upon the type of Epilepsy the individual has. Some seizures may be very noticeable while some may go completely unrecognized. With the most common types of seizures there is some loss of consciousness, but some seizures may only involve small movements of the body or strange feelings.
