does any one know if an over active thyroid releasing a disproportionate amount of t3 and t4 in the blood stream could result in epileptic seizures?
More to the point can the thyroid gland accumulate t3 and t4 over a period of time and then somehow releasing it in one shot causing an epileptic seizure.
Within that vein does anyone know if the effects of hyperactive thyroid medicine would react with anti seizure drugs reducing in effect their effectiveness.
For in this case my girlfriend is being treated for hyperthyroidism for a bit more than a year and has had 6 seizures since august with no apparent trigger that would normally be associated with epileptic episodes.
Does anyone know were to find more information on possible connections between these two diseases.
Thank you

true knowledge can only come when we understand past our
own limited perceptions.

I am a 52 year old woman who has supposedly had Epilepsy since I am 6 years old,but I have only had 3 seizures my entire life, the first when I was six and the last 30 years ago when I was pregnant.Each seizure came when I was very sick under physical stress.I have recently been diagnosed with Hyperthyroidism and since, especially today am having all the signs, symptoms, precursors of a seizure.Today was awful racing heart, weird sensations in my abddomen, hyper past tolerability, twitching face, excessively blinking eyes,weird feeling in my head,trouble seeing (eyes pulling) petit mals,all the aura of a seizure coming. Very bad.Is the Hyperthyroidism affecting my Epilepsy? I was not experiencing any of this before. Please write me..Thank you.

seizures and hyperthyroidism
my husband has hyperthyroidism just diagnosed this year along with seizures. No known cause for the seizures. I am suspecting it is linked to his overactive thyroid. It is a well known fact that hormone imbalances can indeed lower someones seizure threshold if they are prone to seizures. However whether or not it is the root cause for his seizure is still unknown. But I suspect once his hormones are corrected that his seizures will also subside or hopefully stop completely.

Thyroid and seizures
Well, I seem to fall into this group as well! I had the Thyroid storm, so we decided on the radioactive iodine. Well about a year later came the seizures I have about anywhere from 1 a day if I am lucky and on the bad days they can be about 30 min apart while on meds! we are still working on a defenitive answer so far I am told to persue a treatment called IVIG so we shall see?
