epileptogenesis
Pronunciation: ep-i-LEP-to-gen-e-sis
The 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 networks become hyperexcitable and capable of generating spontaneous epileptic seizures. This process involves molecular, cellular, and network-level changes including alterations in ion channel expression, synaptic reorganization, and neuronal cell death. Understanding epileptogenesis is crucial for interpreting neurophysiological findings in patients at risk for developing epilepsy following brain injury.
Usage
Usage note: Distinguished from 'epileptiform' (resembling epilepsy) and 'epileptic' (relating to established epilepsy).
