چکیده

AIMS Sudden unexpected death in epilepsy (SUDEP) is one of the leading causes of death in people with epilepsy. For classification of definite SUDEP, a post mortem (PM), including anatomical and toxicological examination, is mandatory to exclude other causes of death. We audited PM practice as well as the value of brain examination in SUDEP. METHODS We reviewed 145 PM reports in SUDEP cases from four UK neuropathology centres. Data were extracted for clinical epilepsy details, circumstances of death and neuropathological findings. RESULTS Macroscopic brain abnormalities were identified in 52% of cases. Mild brain swelling was present in 28%, and microscopic pathologies relevant to cause or effect of seizures were seen in 89%. Examination based on whole fixed brains (76.6% of all PMs), and systematic regional sampling was associated with higher detection rates of underlying pathology (P < 0.01). Information was more frequently recorded regarding circumstances of death and body position/location than clinical epilepsy history and investigations. CONCLUSION Our findings support the contribution of examination of the whole fixed brain in SUDEP, with high rates of detection of relevant pathology. Availability of full clinical epilepsy-related information at the time of PM could potentially further improve detection through targeted tissue sampling. Apart from confirmation of SUDEP, complete neuropathological examination contributes to evaluation of risk factors as well as helping to direct future research into underlying causes.

MINI-SYMPOSIUM: THE AUTOPSY IN SUDDEN UNEXPECTED ADULT DEATH The autopsy in sudden unexpected adult death: Epilepsy

ee front matter & 2007 dip.2007.05.004 7676 2196; fax: +44 20 7 ess: [email protected] Summary There are up to 500 epilepsy-related deaths annually in the UK, many of which are unwitnessed. Likely mechanisms for sudden and unexpected death in epilepsy (SUDEP) are cerebrogenic cardiac arrhythmias, or central respiratory depression occurring during the peri-ictal period. Pathologists should be inf...

Sudden unexpected death in epilepsy: a series of witnessed deaths.

OBJECTIVES Sudden unexpected death in epilepsy (SUDEP) represents a significant category of mortality in the population with chronic epilepsy. A consistent feature is that most of these deaths are unwitnessed. The aim was to identify witnessed deaths, examine the circumstances, and relate these findings to the proposed mechanisms for SUDEP. METHODS During the course of case ascertainment for ...

Sudden unexpected death in epilepsy: basic mechanisms and clinical implications for prevention.

Sudden unexpected death in epilepsy (SUDEP) is the most common cause of death in patients with intractable epilepsy. The substantial lifetime risk of SUDEP and the lack of a clear pathophysiological connection between epilepsy itself and sudden death have fuelled increased attention to this phenomenon. Understanding the mechanisms underlying SUDEP is paramount to developing preventative strateg...

Sudden unexpected death in epilepsy.

Mortality in people with epilepsy is two- to three-times that of the general population. This can be attributed to epilepsy itself (epilepsy-related death) or to the underlying cause of the epilepsy. Sudden unexpected death in epilepsy (SUDEP) is the commonest cause of epilepsy-related death. It is a syndrome where a person with epilepsy dies suddenly and no other cause of death is found. There...

Sudden unexpected death in epilepsy patients is often misdiagnosed as sudden cardiac death.

Sudden unexpected death in epilepsy patients (SUDEP) represents the second main neurologic cause of years of potential life lost, following stroke, with a cumulative lifetime risk reaching 8% for childhood-onset epilepsy. In light of these worrying figures, the American Academy of Neurology (AAN) has recently published practice guidelines on the risk of SUDEP. These guidelines emphasize the “co...
