Over 70 million people worldwide suffer from epilepsy-one of the most prevalent chronic neurological disorders[1].Despite the availability of over thirty anti-seizure drugs(ASDs)that mainly act on voltage-gated ion channels or inhibitory GABAergic receptors,the effectiveness of these drugs in achieving seizure freedom remains unsatisfactory due to pharmacoresistance and the inevitable occurrence of side-effects.
