Epileptogenesis
The process by which a normal brain develops epilepsy after an initial precipitating injury.
Full Definition
Epileptogenesis refers to the complex biological process through which a previously normal brain undergoes pathological changes that lead to the development of spontaneous recurrent seizures. This process typically follows an initial brain insult such as trauma, stroke, or infection, and involves molecular, cellular, and network-level alterations that transform normal neural circuits into hyperexcitable epileptogenic networks. The latent period between the initial injury and the onset of epilepsy can range from months to years, making this process a critical target for therapeutic intervention.
Usage
Usage note: Often confused with 'epileptogenic' (seizure-generating) and 'epileptiform' (seizure-like patterns on EEG).
