Sudden death in a child with epilepsy: potential cerebellar mechanisms?

Epilepsy is the most common neurological disorder in humans. People with epilepsy are more likely to die prematurely than those without epilepsy, with the most common epilepsy-related category of death being sudden unexpected death in epilepsy (SUDEP). The central mechanisms underlying the fatal process remain unclear, but cardiac and respiratory mechanisms appear to be involved. Recently, cerebellar, thalamic, basal ganglia and limbic brain structures have been shown to be implicated in respiratory and cardiac rate regulation. We discuss here the potential mechanisms underlying the fatal process, with a description of cerebellar actions likely failing in that SUDEP process
