Re: Memory loss problems

Hi

Sorry to hear you are having memory problems. Many people with epilepsy find they have some memory difficulties. There are a number of reasons why people with epilepsy may have memory difficulties.

Epileptic seizures can affect memory functioning because, in order for memory to work properly, the brain needs continuous self-monitoring. This self-monitoring system can be disrupted during a seizure. Memories before a seizure can be lost, as they have not been fully incorporated into our memory system. During a seizure our memory may also be affected, because a loss of consciousness can interfere with normal brain processes, disrupting the encoding and storage of information. The confusion that can occur following a seizure can also prevent our memory from working properly. Some people with epilepsy can experience unusual electrical activity within the brain between seizures and this can also affect attention and memory functioning.
Some anti-epileptic medications may interfere with memory functioning as they can affect the speed at which the brain can process information. On the other hand they also reduce seizure frequency and, as we have discussed, frequent seizures can also cause memory impairment. If you are worried your medication may be affecting your memory, it is important to speak to your doctor about your concerns. They can investigate this possibility and will discuss possible solutions with you.

Re: Memory loss problems

Memory problems in epilepsy are very common, particularly difficulties in remembering recently learned memories, where distant memories (e.g. of your childhood) tend to be relatively well preserved. All of the mechanisms that Kathy mentions may be relevant, but its likely that in most people there are several causes. These best we can say is that we observe memory problems frequently in people with epilepsy, but often we don't know precisely why they've happened.

Some people are worried that they're developing dementia. Don't be! Its likely that these symptoms will be an irritation, and one of tiresome things about epilepsy that you'll have to learn to live around, but they're very unlikely to cause you any significant problems in your life.
