Seizures…Memory…Depression. YES, They Are Linked! | November 17, 2013


At least one in every eight people with epilepsy also has depression.

Epilepsy can have different effects on memory functions and depression for various reasons.

Because the portion of the brain where memory and emotions are stored — the limbic sysyem – can be disturbed by epileptic seizures.

In fact, memory problems are one of the most reported problems that coincide with epilepsy.

The normal processes that the brain goes through in storing memory may be disrupted during an epileptic seizure.

Loss of consciousness that occurs along with seizures can result in a loss of memory.

Usually, the memory loss is at the time immediately prior to the seizure, however, there have been exceptions to this.

People with Temporal Lobe Eilepsy are especially prone to memory loss.

Because those seizures usually begin in the deeper portions of the temporal lobe — especially the limbic system.

And since TLE is often medication resistant, the result is memory loss, often coupled with depression.

In a study of 70 treatment resistant people, 34% of the people showed significant depression.

They also had poorer performance on measures of intelligence, language, perception, memory, and executive function.

Severity of depressive symptoms were associated with the level of memory impairment in TLE patients.

Especially for people with a left-sided seizure focus.

And at the time of the study, depression seemed to be under-recognized and under-treated, since none of the people were in any kind of treatment.

In addition, it’s also important to understand that epilepsy is more than just a syndrome of seizures.

Other cognitive, behavioral, and emotional changes are present.

Although in the past, these have been generally viewed as side-effects of seizures.

And it has been presumed they would disappear once seizures were adequately controlled.

But since they may precede seizures, these conditions don’t uniformly resolve if seizures are fully controlled.

Therefore, it’s increasingly recognized that to improve the quality of life for many people with epilepsy, a “cure” must involve more than stopping or preventing seizures.

It also must include improving the cognitive, behavioral, and emotional difficulties that can be an equally or more disabling part of this disorder.

Coping with epilepsy is an ongoing battle. And until the physiological and emotional issues are addressed, the struggle will continue.

  1. love your blog and I love this posting. Right on the money with the psych issues. a lot of neurologists will prescribe antidepressants along with aem’s. I’ve found that alot of those issues can be countered with the use of medical marijuana. Sounds horrible and needs more study but the kids with dravets seem to benefiting through cbd production in the plants. Kinda off topic but not. I am intractable and dosed high with keppraxr—the stuff made me irrational and hateful, depressed. trying mmj to counter those effects has vastly improved my quality of life. I’m much happier and my wife and kids love that I had the courage to step in that direction.

  2. We’re on the same side of the boat.

    Take a look at “Medical Marijuana — The Great Debate”

    http://epilepsytalk.com/2012/07/03/medical-marijuana-the-great-debate/

    You’ll see in the bottom links that even the FDA is beginning to the the light. (Clinical trials!)

    Even though the AMA continues to keep their heads in the sand. (Competition? Fear?Arrogance?)

  3. While I’m NOT expert, nor as much infromed as in “medical-marijuana” as much as my Dilantin or Keppra seizure prescriptions, your article ended hits home detailing the enormous struggle overcoming confusion, depression & memory problems, after getting out weeks in the hospital, just yesterday.
    Thank you for sharing this great article, mapping the enormous struggle for recovery & restart life, all over again.
    This website has ALWAYS been, home to recovery after each seizure.
    So remains your article.
    Thanks for sharing.

  5. Memory loss is one of the things that scares me the most. I wonder if it can mitigated in any manner? Or, if it is inevitable regardless whether you have your seizures controlled or not (due to sub clinical activity)?

  6. I think memory loss is something you have to work on yourself. It scares me too.

    And it’s not going to go away. There’s no magic pill.

    All you can do is try your best. :-(

  8. Ironically Cathy, I saw the same article. I think the problem in legalizing marijuana is that MEDICINAL marijuana is far different (and, of course, meant for very different reasons) than recreational marijuana.

    “Opponents of medical marijuana argue that it is too dangerous to use, lacks FDA-approval, and that various legal drugs make marijuana use unnecessary.

    They say marijuana is addictive, leads to harder drug use, interferes with fertility, impairs driving ability, and injures the lungs, immune system, and brain. They say that medical marijuana is a front for drug legalization and recreational use.”

    http://medicalmarijuana.procon.org/

    We’ve probably all read about the big-time problems in Colorado where recreational marijuana (which we used to call “dope” when we were teens) has been abused and fear is pretty universal that medicinal marijuana will end up being used and abused the same way.

    But, at the end of the day, I think it’s really an issue of money and politics. They don’t care what conditions medicinal marijuana will help. The legalization is taken on unwillingly, and for that reason, all charges from insurance and medical to social are fair game.

    Because in reality, who really is in true favor of medicinal marijuana? Those who NEED it.
