epileptogenesis
Pronunciation: ep-i-LEP-toh-jen-eh-sis
The gradual process by which normal brain tissue develops the capacity to generate spontaneous seizures.
Full Definition
Epileptogenesis refers to the complex biological process through which previously normal neural tissue undergoes pathological changes that ultimately result in the development of spontaneous, recurrent seizures. This process typically follows an initial precipitating injury such as trauma, stroke, infection, or prolonged febrile seizures, and involves molecular, cellular, and network-level changes including neuronal death, gliosis, aberrant neurogenesis, and synaptic reorganization. The latent period between the initial insult and the onset of spontaneous seizures can range from months to years. Understanding epileptogenesis is crucial for developing preventive therapies and identifying biomarkers for epilepsy risk.
Usage
Usage note: Distinguish from ictogenesis (seizure initiation) and seizure propagation.
