Clinical Trial Summary

Epilepsy is a common neurological disease, manifested in the sudden abnormal discharge of neurons leading to short-term brain dysfunction, has become the neurology after headache the second most common disease. In China, the prevalence of epilepsy is about 4.7-8.5 per 1,000, and more than 400,000 new cases of epilepsy are developed each year. Of these, 30% of patients were treated with ineffective medication, developing into a drug-incurable epilepsy that required surgery and other treatments. The most common type of epilepsy is temporal lobe epilepsy, while the common complication in temporal lobe epilepsy is hippocampal sclerosis, which often requires surgical removal. The incidence of inner temporal lobe epilepsy associated with hippocampal sclerosis is increasing, but its exact cause and specific pathogenesis are still unclear, so clarifying its pathogenesis will contribute to the understanding of temporal lobe epilepsy and the improvement of surgical procedures. This study is intended to get single-cell transcriptome as well as spatial transcriptome data of temporal lobe and hippocampus samples. By studying gene expression change associated with epilepsy and hippocampus sclerosis, we intended to find possible prognostic-related molecules and to deepen understanding of pathological changes in epilepsy at the molecular level.
