Epileptic encephalopathy
A condition where epileptic activity itself contributes to cognitive and behavioral impairments that worsen over time.
Full Definition
Epileptic encephalopathy refers to a condition where the epileptic activity itself contributes to progressive disturbance in cerebral function, leading to cognitive and behavioral impairments that are more severe than expected from the underlying pathology alone. The concept emphasizes that frequent seizures and interictal epileptiform activity can cause ongoing brain dysfunction and developmental regression. Examples include West syndrome, Lennox-Gastaut syndrome, and Dravet syndrome. Early and aggressive treatment is crucial as controlling the epileptic activity may improve cognitive outcomes, distinguishing these conditions from static encephalopathies with epilepsy.
Usage
Usage note: Distinguish from static conditions where epilepsy accompanies but doesn't cause the encephalopathy.
