This leaflet explainswhy. It also gives some ideas forimproving memory.Epilepsy is one of the mostcommon serious neurologicalconditions. People with epilepsyhave repeated seizures. Mostseizures will stop with the rightmedication. People can have oneseizure and not have epilepsy.The reason could be a hightemperature or a head injury.Seizures usually last a short time.The brain works normally betweenseizures. Billions of brain cells passmessages to each other and thesecontrol what we say and do. Aseizure can happen if the brain’selectrical activity is disrupted andthese messages get mixed up.03
MemoryWe all forget things like people’snames and where we have leftour keys. When this happens wecan feel frustrated. Our memoryholds so much information it is notsurprising it can sometimes let usdown. Our memory lets us recallevents, people and places and allthe facts we know. We use it tostore and remember everythingwe have learned and experienced.Our memory has two parts; ourshort term memory and longterm memory.Short term memory (STM)We use this memory to rememberinformation for a short time, afew seconds or minutes. It is thenforgotten. Often we remember forlong enough to carry out a task, forexample, buying today’s groceries.04Memory problemsLong term memory (LTM)We use this type of memory tostore and hold details for a longtime. We can usually find thesememories as we need them. Forexample, when we are first givenour bank card security number wehave to learn it and use it beforeit stays in our long term memory.Each time we need to withdrawmoney, our memory gives us thecard number.Information we want to storeusually needs to be practiced orlinked to something we alreadyknow. It then passes from ourshort term memory to our longterm memory. This process ofrepeating information is calledencoding or learning.When we want to remembersomething we find it in our shortor long term memory. Informationpasses daily between these twomemory stores.Memory problems happen fordifferent reasons. There are threestages to memory: learning, storingand finding the memory. Mistakescan take place at any of thesestages causing us to forget. Wemay have problems with certaintypes of memory, such as thoselisted in the table below.MemoryShort termmemoryLong termmemoryVisual memoryVerbal Different ways to rememberWe use different ways to help usremember.

Memoryand epilepsyPeople with epilepsy often havememory difficulties. This canbe for many reasons:Cause of epilepsySome people have a cause fortheir epilepsy. This can be due todamage to the brain from a headinjury or infection. If part of thebrain that deals with memoryis damaged this could lead tosome memory loss. People withtemporal lobe epilepsy often havememory problems. This is becausethe temporal lobe is where welearn new memories.SeizuresA person’s memory can beaffected before, during andafter a seizure. Changes in thebrain before a seizure can meaninformation is not processed wellenough to pass to our long termmemory. Awareness can also beaffected during a seizure. Thismeans people have little or norecollection of what has happened.Even between seizures a person’smemory may be affected. Thisis because brain activity may bedisrupted even though it is notenough to lead to a seizure.Epilepsy medicationMany people worry that themedication they take for theirepilepsy causes poor memory.The side effects of somemedication (for example poorconcentration and drowsiness) canaffect remembering. However,your memory will be improvedif the drugs stop or lower thenumber of seizures you have.06If you feel your medication affectsyour memory speak to yourGP, nurse or epilepsy specialist.Do not stop your epilepsymedication without medicaladvice.SurgerySome people with epilepsy havesurgery to try and stop seizures.Sometimes people have memoryproblems as a result of the surgery.MoodHow we feel can affect ourconcentration and attention,which can then affect our memory.Research shows that people withepilepsy are more likely to bedepressed or anxious. If our brainsare overloaded by these feelingswe can become distracted andunable to focus on information.In turn this will affect our memory.Lack of sleepPeople with epilepsy need to haveenough sleep because lack ofsleep can be a trigger for seizures.When you are well-rested yourmemory improves. This is becausetiredness makes people less ableto concentrate, learn and storenew information.07
