Epilepsy is a disorder of the brain in which sudden abnormal discharges of neurons cause transient dysfunction and is a common disorder of the nervous system. Although most patients experience remission of symptoms with medication, about 20 ~ 30% of patients still have poor outcomes with medication and progress to refractory epilepsy. The etiology of epilepsy is complex and the exact pathogenesis is not yet clear. Current research has explored the pathophysiological mechanisms underlying epileptogenesis, thus providing a basis for identifying potential therapeutic targets for epilepsy and advancing the precision treatment of epilepsy. p38 Mitogen-activated protein kinase (MAPK) signalling pathway is a conserved class of kinases involved in many physiological/pathological processes by regulating intracellular gene expression levels, cell division, differentiation and apoptosis in response to various extracellular stimuli in order to mediate intracellular signalling cascades. The p38 MAPK signalling pathway is one of the subfamilies of MAPK that mediates inflammatory responses, apoptosis, tissue edema and other biological processes involved in the development of central nervous system diseases. The p38 MAPK signalling pathway is now reviewed for its involvement in the development of epilepsy through unused pathways, in order to identify new potential targets for epilepsy treatment and provide clinical precision.
Patients with autoimmune encephalitis are mainly characterized by behavioral, mental and motor abnormalities, neurological dysfunction, memory deficits and seizures. Different antibody types of autoimmune encephalitis its pathogenesis, clinical characteristics are different, in recent years found immune related epilepsy is closely related to autoimmune encephalitis, based on autoimmune encephalitis type is more, we choose more common autoimmune encephalitis, expounds its characteristics, to help clinical diagnosis.
Febrile seizures (FS) are one of the most common neurological disorders in pediatrics, commonly seen in children from three months to five years of age. Most children with FS have a good prognosis, but some febrile convulsions progress to refractory epilepsy (RE). Epilepsy is a common chronic neurological disorder , and refractory epilepsy accounts for approximately one-third of epilepsies. The etiology of refractory epilepsy is currently complex and diverse, and its mechanisms are not fully understood. There are many pathophysiological changes that occur after febrile convulsions, such as inflammatory responses, changes in the blood-brain barrier, and oxidative stress, which can subsequently potentially lead to refractory epilepsy, and inflammation is always in tandem with all physiological changes as the main response. This article focuses on the pathogenesis of refractory epilepsy resulting from post-febrile convulsions.
