Epilepsy can be described as a group of neurological disorders, characterized by recurrent episodes of convulsive seizures, loss of consciousness, sensory disturbances, abnormal behavior or all of these. Altered glutathione metabolism in association with increased oxidative stress has been implicated in the pathogenesis of many diseases such as seizures .It is therefore reasonable to propose that sialic acid levels can be affected by this pathological state or, alternately, by seizures. In the present study, we observed that the sialic acid levels were significantly different between the experimental groups as well as in the subgroup analysis. The results suggest that glutathione may have a neuroprotective effect by decreasing sialic acid levels in mice brain.
