Memory can be one of the key issues that affects people with epilepsy. This can be for many reasons, including the type of seizures they have, the effects of medication, the effects of epilepsy on concentration or mood, lack of sleep, age, or the effects of epilepsy surgery.

How epilepsy can affect memory

Any type of epileptic seizure could potentially affect your memory, either during or after a seizure. If you have lots of seizures, memory problems might happen more often.

Some people have generalised seizures that affect all of the brain. Others have focal seizures (sometimes called partial seizures) that affect only part of the brain. Some people have both generalised and focal seizures.

If you have focal seizures, the way your seizures can affect your memory will depend on where in the brain your seizures happen.

The brain has two halves called hemispheres. Each half has four parts called lobes: the occipital, parietal, temporal and frontal lobes.

How memory works

Memory is the brain’s ability to store information and find it again later. Chemical and electrical changes happen in the brain when new memories are made.

Three stages of memory

Making and using memories involves three stages: learning the information, storing it, then recalling it. Memory can be affected if any of these stages are disrupted, for example by a break in concentration. 


This is when you want to learn something new, such as a friend’s new address. It may involve repeating the address several times or linking it to an existing memory. For example, linking the address – '1 Albert Square' to the television show Eastenders.


This is when the information learnt is stored permanently in the brain.

Recalling (finding the information)

This is the brain’s way of finding and using the information that has been learnt. For example, remembering a friend’s new address when sending a letter.

Memory aids, reminders and brain training

Consultant neuropsychologist, Dr Sallie Baxendale, gives a presentation on coping with memory problems for people with epilepsy. Watch now.

Memory aids

Memory aids may help you to cope with memory problems. Different aids or reminders may suit different types of memory problems and they work best if they are used regularly as part of a routine. Here are some ideas.

Sticky notes

Sticky notes, such as Post it Notes™ can help you to remember to do things. For example, sticking a note to the front door to remind you to pick up your keys before you go out.


Using a calendar can be helpful, particularly if it is placed somewhere you will see it easily and often, such as on the fridge door.

Diaries, journals and ‘to do’ lists

Using a diary can help you to keep note of appointments, birthdays or phone numbers. Keeping more detailed notes in a diary may be helpful to keep track of people you have met, where you have been and what you did. A diary can also be a handy way of recording seizures.

A 'to do’ list can be useful to record daily tasks, for example phone calls to make, bills to pay. Email, mobile phones and computer software often include diaries and 'to do' lists. 

Memory apps

Here's a selection of apps which you may find useful for helping to manage your epilepsy and other related issues.

Laura's story

Laura Grainger cannot remember her own wedding day, most holidays and birthdays, or the time she spent at university. The impact of her epilepsy means that memory loss is a huge factor in her life.

How memory works

Throughout our lives, memories are being made, stored and found by our brain. Links made between our brain cells help us to remember the thoughts, skills, experiences and knowledge that make each of us unique. Memory can be one of the key issues that affects people with epilepsy.
