Seizure Research


I have been trying to do at least some homework on Petit Mal Seizures today so that I am prepared for a more educated conversation with the Dr. In doing so, I have found out a few things that have raised some questions for me.

Here are statements from a few websites that caught my attention:

“Absence (petit mal) seizures begin in childhood, usually between the ages of 5 and 15. They do not produce the convulsions and other dramatic symptoms of tonic-clonic seizures. A person does not fall down, collapse, or move jerkily. Instead, the person has episodes of staring with fluttering eyelids and sometimes twitching facial muscles. The person is completely unaware of the surroundings. These episodes last 2 to 3 seconds and, rarely, 10 to 30 seconds. The person abruptly stops activity and resumes it just as abruptly, experiencing no after-effects and not knowing that a seizure has occurred.”

Above excerpt quoted from HERE.

“Petit mal seizures often affect people younger than 20, and children between the ages of 4 and 12 are most likely to have them. Most children with petit mal seizures have an otherwise normal neurological system. Many can expect to outgrow the disorder. Children who were young when the seizures first started, who have no other neurological problems and who have seizures well controlled by medications are most likely to outgrow their seizures. In about half of children with petit mal seizures, the seizures will progress to grand mal seizures”

Above exerpt quoted from HERE.

So here is what bothers me about the above:

1. Ty is only 2. Apparently the age of 4 or 5 is a more “normal” starting age for this. I assume starting earlier is not a great sign.

2. The typical seizure lasts only 2 to 3 seconds. Who on earth would catch that? The fact that I have noticed this is because what I have seen has lasted definitely over 10 seconds and sometimes over 30. If this is the case, Ty could be having a lot more seizures than I know because I am only seeing the more lengthy ones. I would say the ones that happen over 10 seconds have been occurring every week but not every day. In fact, since I mentioned this last week, I haven’t seen anything alarming. A few short ones maybe. So having said this, what does “rare” mean?

3. The very last line made my heart sink. IN ABOUT HALF OF CHILDREN WITH PETIT MAL SEIZURES, THE SEIZURES WILL PROGRESS TO GRAND MAL SEIZURES. Also, I noticed that most of these articles are written assuming the majority of the seizures have no known cause. In Ty’s case we do know the cause. Bilateral hemorrhages and PVL – thus this makes me assume he would more easily “qualify” for progression but my heart can’t go there right now.

4. I did a little drug research and one of the drugs used for Petit Mal Seizures is Theophyiline. This drug is used most commonly for respiratory issues (it is like caffeine) and Ty was on it for awhile when he came home from the NICU to help with his apnea issues. It seems to me that someone may have mentioned that it is also used for seizures and it made me wonder at the time if Ty may have had seizures without it. I could be dreaming all this up though and now I can’t find the darn article I was looking at and every reference to this drug I have found only references the respiratory issues. I hate when I lose track of web articles.

5. I assume Ty is of the category less likely to “outgrow” these because of the root problem. He will not outgrow his IVH and PVL. If they are causing these issues, short of a miracle, I doubt they will resolve. Damage is done.

I did a search today on IVH and seizures and came across a very detailed article on hemorrhages, and PVL. The most common outcome of this combination is cerebral palsy and seizures – THIS is why I am hypersensitive to this at the moment because both of these outcomes are expected for Ty and there is more and more evidence that he will diagnosed with both. HOWEVER – let me share something that I think is amazing. When I was in the NICU and read about PVL, I flipped out and forced myself off the computer. In recent months I haven’t gone back to it. Read the below excerpt from THIS article and you’ll see what had me freaking out in those NICU days.

Prognosis:

Grade I and grade II hemorrhage: Neurodevelopmental prognosis is excellent (ie, perhaps slightly worse than infants of similar gestational ages without PVH-IVH).

Grade III hemorrhage without white matter disease: Mortality is less than 10%. Of these patients, 30-40% have subsequent cognitive or motor disorders.

Grade IV (severe PVH-IVH) IVH with either periventricular hemorrhagic infarction and/or periventricular leukomalacia: Mortality approaches 80%. A 90% incidence of severe neurological sequelae including cognitive and motor disturbances exists.

So let me take you back to Ty’s diagnosis:

Initially I was told he had a grade 4 IVH on his right side and a grade 3 on the left. Later they downgraded the 3 to a 2. When Ty was six months old we had a CAT scan done and PVL was determined. Ty’s hemorrhages, while technically resolved, killed off white matter in the brain that surrounded his ventricles. As a result, the ventricles never reduced in size because the brain doesn’t allow for “dead” space. The ventricles will always be swollen now because they are filling in the areas where the white matter died due to prolonged swelling of the ventricles due to the hemorrhages. Clear as mud?

I COULDN’T BELIEVE MY EYES TODAY WHEN I READ THAT MORTALITY APPROACHES 80%!!!! We have reason to PRAISE PRAISE PRAISE. Considering Ty’s diagnosis, God has covered him miraculously! (That 80% refers to the babies in the NICU – Ty was obviously one of the 20% that survived this!)

God is good all the time – all the time God is good.

About the EEG:

My family has been asking me how in the world an EEG will “happen” to catch Ty in a seizure state. The nurse offered a good explanation and I thought I would share it.

She compared it to a geologist using a seismograph. When geologists are observing earthquake possibilities they watch a seismograph. It takes a “build up” for an earthquake to shake the ground and the trembling is then graded. Just because you can’t see it or feel it though, doesn’t mean it isn’t going on beneath the surface. That is why earthquakes are often predicted. The geologists can read a seismograph and watch the build up effect. They see what happens below the surface that we can’t feel or see. An EEG is similar. In all likelihood an actual active seizure will not be seen however, the brain waves are likely to be reflecting a “build up” of sorts if seizure activity has/will be occurring. The “evidence” so to speak is usually there despite the charting of an active seizure. Thought you’d like to know that ;).

Tomorrow I will be keeping up Ty late and getting him up early on Thursday so he is sleep deprived for his test. Aunt Beck will watch Tanner and Sweetie will go with me to try to keep Ty awake in the car. She might be needed to get him to sleep too. She often has better luck than mama does. So that is my update.

P.S. Jim took me and the boys to Blue Ridge over the weekend to get away. We had a great time. I’ll post pictures later.

  1. i can certainly understand why this has been a frightening journey!

    i often wonder on some of the descriptions we find for all sorts of medical issues are out of date or simply not up-to-date based on lack of knowledge… like the so many seconds or age group etc… i wonder if those descriptions took preemies into consideration and the special circumstances surrounding them and the higher risk etc…. sigh… praying with you – trusting Father.

  2. I wonder that too. I can say from experience though, that kids with LESSER hemorrages/PVL issues than Ty has, have had higher degress of CP and seizures. I have talked to many other micro preemie mom’s via this website and preemie forums and it seems to me that if a child is born in the 23 to 29 week range, has bilateral grade 3 or 4 hemorrages and PVL, they do not escape CP and seizures without miraculous intervention. I don’t want to lose hope on this but I also see some writing on the wall here. Even still, it seems to me that Ty’s disabilities have all the potential in the world to be very very mild ESPECIALLY considering what his diagnosis is. By the way, did I mention that he is trying his best to sing his ABC’s? Not doing too darn bad either:).

  3. Well, there is light in the midst of concern then isn’t there – darling abc boy!!!! That’s GREAT for giving a mama a hopeful heart.

    All the rest is certainly enough to warrant watching with concern… and the abc’s and the way he’s defied the odds on so many other things is enough to warrant moooore hope.

    I know this is a bit of a roller coaster…. I’m praying and loving you.

  4. Ok that was not a fair warning here…..I have not been back to the PVL pages since the NICU days they scared the “””crap”””(oops) out of me and i promised myself I would never read up on that again. :)LOL That was a good article and yes i do know why you were freaking out in the midst of diagnoses and reading up on IVH and PVL…..I never dealt w/ IVH but did deal a lot w/ PVL. We have miracles to hold today, because Kenslie has severe PVL….her neurologist cant believe she walked into his office after he saw her scans last year. He said he is definitely surprised that she was only diagnosed w/ mild CP and then proven that she does not have CP at all. And Ty is starting to sing ABC’s????

    God is good……

  5. I am sorry that I haven’t been keeping updated with this, but today I thought I needed to come and visit and catch up on everything. I am sorry to hear about Ty. Jordan who is 5 was diagnosed with epilepsy at the age of 2. It started with the starring spells and then grew into the gran mal seizures and now he has both. The doctors are not sure if the will grow out of his, but his is caused by the undersizing of the right brain. His right side is smaller than the left, and the reason for this is unknow. He has been on a few different epileptic medicine and the best one I think so far is Lamictal. I think depakote is a very bad drug so I for sure don’t consider that, tegretol is a good one and also topamax. How ever topamax made Jordan have many mood swings. Jordan’s EEG’s have been postive with epileptic patterns and his Speech Therapist was the one that old me he was having the starring spells. I didn’t pay any attention to it, I thought Jordan was just ignoring me. Sure enough she was right. Just so you know, don’t be surprised if the EEG comes back negative the first time. That is what our nuero doctor told us. Good luck and I will be checking back in…

  6. Doni-I just wanted to say good luck with the appointment. We had Shay (5) go get an EEG for kind of the things you describe with Ty. His came back normal and the doctor said he should grow out of his spells. Shay was a full term baby. I didn’t understand any of it considering we are a pretty healthy family. He said it develops in normal children and will fade away hopefully by the time he is a teenager. I do hope it will. Right now we have to worry about other children making fun of him when he has his esposides. He will be in the first grade next year and last year the kids didn’t seem to care. I know it gets harder as they get older.

    The EEG was interesting. It was fun getting up with him at 3 am for his appointment at 8am. He didn’t even fall asleep, of course he started to on the way there and was out on the way back…lol That is weird his appointment isn’t earlier in the day. But if he still naps I guess he would be tired by the time he gets there. Good luck! Jere’
