epileptogenesis
Pronunciation: eh-pih-LEP-toh-jen-eh-sis
The process by which normal brain tissue becomes epileptic and capable of generating spontaneous seizures.
Full Definition
Epileptogenesis refers to the complex molecular and cellular changes that transform normal neural networks into hyperexcitable circuits prone to seizure generation. This process often follows brain injury, infection, or other precipitating events and may involve neuroinflammation, gliosis, and synaptic reorganization. Understanding epileptogenesis is crucial for developing preventive therapies and guides research into biomarkers that might predict epilepsy development. In clinical documentation, the latent period between initial injury and first seizure represents the epileptogenic process.
Usage
Usage note: Refers to the process, not the capacity (epileptogenicity) or seizure generation (ictogenesis).
