Epileptic seizures originate in various
parts of the brain. The seizure may affect one’s memory if it
affects the temporal lobe, especially the hippocampus. Damage to the
left side of the brain is more likely to cause difficulty with verbal
memory, such as remembering conversations and written material,
whereas damage to the right side can affect visual memory such as
scenes or directions. Antiepileptic medications, such as Dilantin,
can also cause memory loss.
During a seizure, a person will not be
able to encode or learn any information from what is going on around
them. This causes memory gaps. The more frequent the seizures, the
more frequent the gaps in memory.
