Glioma related epilepsy (GRE) is a complication that seriously affects the quality of life and treatment process of glioma patients. The genes and biomolecules in the tumor microenvironment may contribute to the mechanisms and pathways of epilepsy. In addition, it has been found that epileptic seizures can promote the growth of brain tumors, making controlling epilepsy a key factor in treating brain tumors., However, in current understanding, not all genetic molecular features carried by gliomas themselves are involved in the pathogenesis of GRE. With the deepening understanding of GRE, it has been discovered that some molecular features of gliomas are involved in the pathogenesis of GRE, mainly through the Ras/Raf/MAPK (MEK)/ERK and PI3K/AKT/mTOR pathways, which are also involved in the pathogenesis of gliomas. In 2021, the World Health Organization (WHO) classified diffuse gliomas into two categories: adult and pediatric, and further subdivided them into types such as astrocytoma, oligodendroglioma, and glioblastoma. This classification helps to more accurately understand and apply the molecular characteristics of gliomas, promote the standardization of tumor pathological diagnosis, and may have an impact on the treatment and prognosis evaluation of GRE. This review links genes and biomolecules in the tumor microenvironment through the latest WHO classification, summarizes previous research and recent findings, and provides a deeper understanding of the molecular characteristics of gliomas and their relationship with epilepsy related molecular pathways. It explores more effective treatment methods to suppress epilepsy symptoms and tumor growth, which is of great significance for improving the diagnosis and treatment of GRE.
