//

Objective:/ /--- Glutathione in its reduced form (GSH) is^ the most

important free radical scavenging compound in the mammalian^ nervous

system that prevents membrane lipid peroxidation. It^ is suspected that

epileptic seizures are accompanied by a massive^ production of reactive

oxygen species, i.e., oxidative stress.^

//Methods://--- Using an ^1 H MRS technique developed at the authors'^

site, the authors measured glutathione levels in a volume of^ interest

(VOI) of 25 x 25 x 25 mm placed in structurally normal-appearing^ tissue

in the parietooccipital region of each hemispheres in^ patients with and

without active epilepsy, and in a age-matched^ control group.^

//Results://--- The GSH/water ratio in patients with epilepsy^ was

significantly reduced in the parietooccipital region of^ both

hemispheres (1.6 ± 1.0 x 10^- ^5 ) compared to the GSH/water^ ratio in

healthy controls (2.4 ± 1.1 x 10^- ^5 ). There was^ no significant

difference between the hemisphere with epileptogenic^ focus and the

hemisphere without epileptogenic focus. The GSH/water^ ratios of the

patients without active epilepsy were not different^ from the GSH/water

ratios of patients with active epilepsy.^

//Conclusion://--- The authors found evidence for a widespread^

impairment of the glutathione system in patients with epilepsy^

independent from seizure activity.

Hi ,

Once again an amazing article! I am not scientist and was wondering if you could

just briefly tell me how they measured the Glutathione. It said water ratio- did

they take a specimen from the brain??? I am interested because my son has

seizures and this is the only thing he tested low on out of all the DAN protocol

tests. I did give him the cream and one IV but saw an INCREASE in seizures so I

stopped.

I wish this article went further and addressed whether we could replace

glutathione effectively.

Thank you Thank you thank you for all your posts!!!!
