Epilepsy can cause problems with memory, both in the short-term and long-term. In the short term, seizures can interfere with the ability to form new memories or recall recent events. This is called anterograde amnesia.  Long-term epilepsy can lead to problems with memory and cognition, such as difficulty learning new information or retaining information over time. This is known as dementia. Dementia from epilepsy differs from Alzheimer's disease but shares some similar symptoms.
