Is epilepsy a contagious disease?

Often when someone falls down, loses consciousness, and gets a seizure we feel scared to help him/her because we think it might be something dangerous and contagious. But it’s not true at all. 
Science confirms that a person with epilepsy or who gets seizures is not a contagious person and we should help him/her to recover as soon as possible.
A person experiencing a seizure is not contagious by saliva or by touching the person itself. Epilepsy is a brain disorder and the seizure can be one of its symptoms.
