About The Webinar

This session will review seizure activity characteristics in an effort to distinguish them from other causes of collapse and involuntary movement.


The term seizure refers to a sudden attack or recurrence of disease and often implies a dramatic or catastrophic event. The term is therefore non-specific although is often used to describe an epileptic seizure. The term is often used interchangeably with convulsion.

Epileptic seizure:

An epileptic seizure is the physical manifestation of paroxysmal transient disturbance of central nervous system function resulting from excessive and/or hypersynchronous abnormal neuronal activity within the cerebral cortex.


Epilepsy is not a specific disease but a chronic condition characterised by recurrent epileptic seizures. A patient having a single epileptic seizure does not have epilepsy, as the seizures are not recurrent.
