Slow brainwaves 'cause seizures'

Low levels of electrical activity in the brain may cause some people with epilepsy to have seizures, says experts.

A team of international scientists carried out tests on 14 people with epilepsy and two without.

They found that activity in the outer part of the brain slowed significantly when those with epilepsy were asleep.

Writing in the Proceedings of the National Academy of Sciences, they said it may explain why many have seizures after falling asleep.

There is other links on the page and if u need others just post and i will supply.

What is the hertz range of slow-wave sleep that might just set these seizures off? And are they specifically in the temporal lobe, or is an entire-brain phenomenon?

[EDIT: Looking at the MRI included, the right prefontral lobe is showing this activity. Bizzare.]

Gryff,
Thanks for that info. I often wondered why sleep would often set off a seizure.
If you have other links, I woluld appreciate them

Deus....

Hope this helps hun

details on Photo epilepsy

More to come..

Thanks gryff... but I meant at what Hz in teh slow wave sleep pattern do these seizures begin?

I've sort fo taken up neuroscience...bad habit.

Here is a site i found when i was researching for a friend a few days ago...

Research

Gives lots of information on epilepsy and the diffrent factors and treatments.

Its from the National Institute of Neurological Disorders and Strokes.

cheers

My thanks too, Gryff. I appreciate your research!

Interesting info on the EEG in regrds to seizure diagnosis. A friend's doctor insisted on an EEG on every visit. When the friend questioned what good they would be when the patient was not seizing, the doctor backed off asking to have the test performed.
I alwyas wondered why.
