Astaxanthin rescues neuron loss and attenuates oxidative stress induced by amygdala kindling in adult rat hippocampus.

Oxidative stress plays an important role in the neuronal damage induced by epilepsy. The present study assessed the possible neuroprotective effects of astaxanthin (ATX) on neuronal damage, in hippocampal CA3 neurons following amygdala kindling. Male Sprague-Dawley rats were chronically kindled in the amygdala and ATX or equal volume of vehicle was given by intraperitoneally.

Environmental enrichment restores cognitive deficits induced by prenatal maternal seizure.

Maternal seizure has adverse effects on brain histology as well as on learning and memory ability in progeny. An enriched environment (EE) is known to promote structural changes in the brain and improve cognitive and motor deficits following a variety of brain injuries. Whether EE treatment in early postnatal periods could restore cognitive impairment induced by prenatal maternal seizure is unknown.

Effects of epigallocatechin-3-gallate on pentylenetetrazole-induced kindling, cognitive impairment and oxidative stress in rats.

Cognitive dysfunction is commonly observed in epileptic patients. It has been shown that not only epilepsy but also antiepileptic drugs could induce cognitive impairment. Thus, there is an urgent need for drugs that can suppress seizures without causing cognitive deficit.
