RESUMO
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.

Epilepsia é uma das doenças neurológicas mais comuns em seres humanos. Pessoas com epilepsia têm maior chance de morrer prematuramente do que pessoas sem epilepsia, sendo a principal causa de óbito a morte súbita em epilepsia (SUDEP). Os mecanismos centrais envolvidos neste processo fatal não são claros, mas mecanismos cardíacos e respiratórios parecem estar envolvidos. Recentemente, regiões cerebrais como o cerebelo, núcleos talâmicos, gânglios basais e estruturas límbicas foram relacionadas com a variação das frequências cardíaca e respiratória. Aqui, discutiremos potenciais mecanismos envolvidos na SUDEP, com uma descrição do possível papel do cerebelo na sua ocorrência.
