[Sudden death and mortality in epilepsy].

Mortality in epilepsy is 2-3 times higher than in the age- and sex-matched general population. It is the highest in young male epilepsy patients with generalised tonic-clonic seizures living in low socio-economical situation. The main factors of early mortality unrelated to seizures are the neurological conditions underlying epilepsy. Suicide is an important factor first of all in temporal lobe epilepsy. The group of mortality directly related to epilepsy is made up of the high-mortality grand mal status epilepticus rarely seen in treated epilepsy; the accidents related to seizures and sudden unexpected death (SUDEP). The reasons directly related to epilepsy make up about 40 per cent of epilepsy mortality. There is a 20-24-fold increase of the risk of sudden death in epilepsy compared to sudden death in the general population. The main risk of SUDEP is the "severity" of epilepsy signaled by generalized tonic-clonic seizures, resistance to antiepileptic drugs, polytherapy and frequent drug-modifications in adulthood epilepsy. Seizure-dependent autonomic changes as cardiac rhythm and breathing disturbances as well as some antiepileptic drugs and treatment modifications may contribute to the development of SUDEP. The data suggest that the main tools helping to decrease mortality in epilepsy nowadays are as follows: optimal seizure control, effective treatment of concomitant psychiatric conditions and monitoring for potentially dangerous heart dysrhythmias as well as respiration disorders.
