On its own, epilepsy can cause memory loss, specifically about the events that occurred during the time period involving the seizure. There is no clear cause to this condition.
Epileptic amnesia
Memory loss is always present in epileptic seizures, although the extent to which amnesia is experienced can vary from one person to another. Some may have violent seizures during an attack and then report absolutely no memory of the events. Others may experience what is called anterograde amnesia : the kind of memory loss where the brain finds it difficult to process new information. This is a temporary form of memory loss, however a person might soon recover after a period of time.
