Is Epilepsy Inherited? | December 9, 2019

Just because you have a parent, sibling, cousin or aunt who has epilepsy doesn’t necessarily mean you’ll have it also.

In fact, if you have a close relative with epilepsy, the chance of you having epilepsy is only about 2-5%, depending on the specific type of epilepsy.

The risk in the general population is about 1-2%.

On the other hand, there is a 92-98% chance for the close relative of someone with epilepsy to NOT have the same condition!

So, even though the risk in families with epilepsy is higher than in the general population, most people with epilepsy do not have any relatives with seizures, and the great majority of parents with epilepsy do not have children with epilepsy.

Not everyone who carries genes making them more likely to develop epilepsy will do so. Even if the genes are passed on, not every generation in a family will have seizures. And so, like diabetes, epilepsy may skip a generation.

While epilepsy cannot currently be cured, for some people it does eventually go away. One study found that children with idiopathic epilepsy, or epilepsy with an unknown cause, had a 68 to 92% chance of becoming seizure-free by 20 years after their diagnosis.

The odds of becoming seizure-free are not as good for adults, or for children with severe epilepsy syndromes. But it is possible that seizures may decrease or even stop over time. This is more likely if the epilepsy has been well-controlled by medication or if the person has had epilepsy surgery.

The Genetics of Epilepsy

Clinical tests suggest that genetic abnormalities may be some of the most important factors contributing to epilepsy. Some types of epilepsy have been traced to an abnormality in a specific gene.

Researchers estimate that more than 500 genes could play a role in this disorder.

More than 20 different syndromes with epilepsy as a main feature have been mapped to specific genes.

However, it is increasingly clear that, for many forms of epilepsy, genetic abnormalities play only a partial role, perhaps by increasing a person’s susceptibility to seizures that are triggered by an environmental or external factor.

Like photosensitivity. (Did you know that 25% of people with primary generalized epilepsy are photosensitive?)

While abnormal genes sometimes cause epilepsy, they also may influence the disorder in more subtle ways…

Genetic Testing

For example, one study showed that many people with epilepsy have an abnormally active version of a gene that increases resistance to drugs. This may help explain why anticonvulsant drugs do not work for some people.

Genes also may control other aspects of the body’s response to medications and each person’s susceptibility to seizures, or seizure threshold.

Abnormalities in the genes that control neuronal migration – a critical step in brain development – can lead to areas of misplaced or abnormally formed neurons in the brain that can cause epilepsy.

And in some cases, genes may contribute to development of epilepsy even in people with no family history of the disorder.

These people may have a newly developed abnormality, or mutation, in an epilepsy-related gene.

  1. Very interesting points brought up. I have Juvenile Myoclonic Epilepsy, temporal lobe epilepsy, and photosensitive epilepsy. JME is a syndrome that has a genetic component but no other family members have it. Luck of the draw.

  2. Goodmorning Phylis 😊. I always wondered that myself too!! Apparently they could never figure out how I got epilepsy, but I was told the doctors were suspecting someone with encephalopathy of some sort. I know 9 years ago when I was offered surgery I asked wether or not I was born with it? The neurologist told me I was. It was at that time (in the middle of my children’s teen years and one little one) I decided to follow my grandma and great grandmas lead and not go for epilepsy surgery. However it’s always had a little bit of fear I may pass it on to my children. Luckily I never did!! Thank you and please have a very good day today and please take care of yourself 😊🙏🏼🦅😇😘

  4. Ok I remember that article!! Yes I always had it in the back of my head and I did ask when I seen the neurologist too. But in all honesty it almost felt like the neurologist had already made up his mind prior to seeing me and wasn’t willing to hear what I had to say. Until he tried to put me on keppra and my husband took over. I understand specialists are specialty for a reason, but it doesn’t excuse them from listening to the concerns of us as epileptics or our spouses, families or friends. I won’t lie even my husband and I sat there at the end of my appointment and we’re both stunned when u was told to keep my Dilantin and tegretol as emergency medications or INCASE and then the neurologist quickly left the room!!!!! Too bad we can’t all just be down to earth and help eachother without having or coming across as a dictator or too good for the rest of civilization however or whoever they maybe. Thank you Phylis and please have a very good day today 😊

  6. Ya I feel relieved that appointment is actually over and done with now!! However on the other hand I never did understand being told to use the tegretol or Dilantin as rescue medication!!!!!!! Which leads me back to BOLOGNA I AM GOING TO USE THE TEGRETOL AND DILANTIN AS RESCUE MEDICATION!!!!!!! Plus I was down to 10mg clobazam and he bumped that back up to 20mgs!! I am not going back up to 20MGS!!!!!!! Now I am PRAYING MY PHARMACIST CAN CHANGE THAT MEDICATION TO BRAND NAME MEDICATIONS!!!!!!! So I sit and wait to get a call back from the pharmacy now and I did phone my family doctors clinic as well. I guess I wait and see now. P.S. I haven’t received the new medication yet.

  7. Yes your very right. Apparently the pharmacist caught it and were just waiting to see if it can be figured out and written properly as it should have been in the first place. He’s just not sure how long that will take right now. But I never realized how huge the dosage is of the topomax!! It’s being titrated to 1000 mgs a day over time. WOW!! On the flip side that’s WAY LOWER than the tegretol I am now on 1600 mgs/daily and 400mgs/daily of Dilantin and 20mgs of clobazam (I did bring that down to 10mgs/ daily), but I guess it’s going back up again!! DARN IT!!!!!!!

  8. I think each med has it’s own dosage schedule. For example, in one drug, you may take .05 mg. In other, you might take 250 mg.

    (Just a personal example.)

  9. Yes I completely agree!! That must be the titration part of the medication. But I all honesty I would rather deal with this up coming medication opposed to what I have had to deal with for decades!! I JUST PRAY I DON’T have to change it AGAIN!! And that this works and helps me. Thank you Phylis 😊🙏🏼🦅😇💞. Who knows if it does I MIGHT BE ABLE TO MAKE THAT TRIP AFTER ALL!!!!!!! 😘🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🦅🦅🦅🦅🦅😇😇😇😇😇😘😘😘😘😘

  14. I must confess, I smoke too, either outside or in the garage.

    But it must be too cold in Canada to do that!

    And yes, you must always work at a marriage.

  15. Back when I was young the doctors said that there was a 50/50 chance. My grandfather had epilepsy, my mother and one of her 3 sisters had epilepsy and the one with the epilepsy died at age 12. My sister on my mother’s side who was younger than me had epilepsy and one of my cousins from each of my aunt’s has epilepsy.

  16. Goodevening Phylis 😊. Yes we sure have to work OR PRAY HARD SOMETIMES!!!!! As we’re learning right now. When we went to the neurologist last Friday my leg was itchy after my appointment. I was too baffled from my appointment I thought maybe my family washed our clothes in bleach (I’m allergic to bleach). So I bit my lip. On Saturday I figured it would pass so I never said anything to anyone. Sunday came and it got a bit bigger but again I bit my lip!! Finally Monday came and it hurt. So I told my husband somethings wrong but I wasn’t sure what? Yesterday I couldn’t take it anymore!!!!!!! My husband came home and seen my leg and IMMEDIATELY TOOK ME INTO EMERGENCY!!!!!!! Lol but I wouldn’t let him come in with me because I didn’t want him to get sick and sent him home until I finished. Low and behold the nurse came in and started an I.V. (Yes they knew I’m allergic to latex). Then my friend came it and then the doctor. He wasn’t sure if it was an ingrown hair or a spider bite? So they gave me an injection of something and lol ummm that’s all I remember!! Until I woke up thismorning and this time even my hands were puffy and my fingers had a rash and I was home with an I.V.!!!!! So my husband took me in today and YES!!!!!!! I had a reaction to the needle used for I.V. They had to pull the intervenous and I opted for the injection directly into me and they removed the I.V. Turns out my leg is infected from a suspected spider bite!!!!!!! I ended up laughing and telling them “SEE!!!!! I TOLD YOU I AM ALLERGIC TO NEUROLOGISTS!!!!!!!”. 😂😂😆😆😂😂😂😂😂. What a rollercoaster year!! Lol

  18. I have constant partial seizures, diagnosed nearly 8 years ago, cannot get it Controlled by meds, and not able to have surgery.
    My brother now aged 52, has now been diagnosed with constant partial seizures, apparently, our father was known to have funny turns, we are unable to ask question as Our parents have both passed on.
    .I am particularly worried as life passes by, I was a very independent person, with friends all over Britain.
    I feel particularly vulnerable, when out, as I know of cases where a person has had a seizure, and been robbed or attacked.
    The need of more information is needed for the general public about Epilepsy,
    A friend has also told me she was diagnosed at the age of 12, and her cousin also diagnosed with the same. My heart goes out to all with being diagnosed with Epilepsy, we constantly fight for a good seizure free day.

    • Oh Sandy, have you told your friends or a few close ones you have epilepsy? Or do you feel too vulnerable?

      This link may be of use:

      Explaining Epilepsy to a Friend

      https://epilepsytalk.com/2014/11/29/explaining-epilepsy-to-a-friend/

      The reason for this forum is to help and advocate for one another.

      But being strong in the outside world is tough. Especially when you get a “sucker punch” like epilepsy.

      The only thing you can do is speak up and speak out. Be confident in who you are and don’t let epilepsy define you.

      It took years until I was comfortable enough to come out of the closet. And it was a liberating experience.

      Perhaps you’ll find some comfort in this:

  19. Hello,

    My Aunt, her Daughter and her grand daughter (3 generations)all have an elliptic gene it is severe in my the grand daughter(due to the father also having the gene). However, my mother and my nan have both been tested and they do not carry the gene.

    What is the likelihood that I would also have this gene? I’m unsure if I should be tested and if this is something I should worry about?

    Thank you

    • I’m not sure you should be worried, since epilepsy often skips a generation.

      But for ease of mind, I think you should be tested.

      As I said: Just because you have a parent, sibling, cousin or aunt who has epilepsy doesn’t necessarily mean you’ll have it also.

      In fact, if you have a close relative with epilepsy, the chance of you having epilepsy is only about 2-5%, depending on the specific type of epilepsy.

      The risk in the general population is about 1-2%.

      On the other hand, there is a 92-98% chance for the close relative of someone with epilepsy to NOT have the same condition!

      So, even though the risk in families with epilepsy is higher than in the general population, most people with epilepsy do not have any relatives with seizures, and the great majority of parents with epilepsy do not have children with epilepsy.
