Empagliflozin (EMPA) is one of the sodium/glucose cotransporter 2 (SGLT2) inhibitors that has been recently approved for the treatment of diabetes mellitus type II. Recently, EMPA has shown protective effects in different neurological disorders, besides its antidiabetic activity. Kindling is a relevant model to study epilepsy and neuroplasticity.

Epilepsy is a chronic neurological disease characterized by recurrent seizures caused by abnormal electrical activity in the brain. The aim of our study was to investigate the effect of tDCS on oxidative stress, Ca, glutamate, GABA, AMPAR1, and NMDAR1 levels in kindling-induced epilepsy model. Behavioral tests evaluated motor and cognitive functions, while assessing oxidative stress, Ca, glutamate, GABA, AMPAR1, and NMDAR1 levels in hippocampal tissue.

Epilepsy is a chronic neurological disorder, and its prevalence presents a bimodal distribution with high incidences in children and older adults. The incidence of epilepsy does not generally differ between men and women; however, whether this holds true for new-onset epilepsy in older adults is unclear. While studies in animal models of epilepsy may help explore the biological mechanisms relevant to the influences of sex on epileptogenesis, relatively little information is available regarding sex differences in the genesis of epileptic seizures in middle-aged animals.

Hippocampal-dependent cognitive impairments are consequences of temporal lobe epilepsy. This study aimed to assess the modulatory effects of fenoprofen on Pentylenetetrazol (PTZ)-induced cognitive dysfunction in the rat model of epilepsy. Male Wistar rats were randomly divided into five groups.

Clinical studies have shown that epileptic seizures worsen Alzheimer's disease (AD) pathology and related cognitive deficits; however, the underlying mechanism is unclear. To assess the effects of seizures on the progression of AD, chronic temporal lobe epilepsy was induced in five familial AD mutation (5×FAD) mice by kindling with the chemoconvulsant pentylenetetrazole (PTZ) at 3-3.5 months of age.
