About Sudden Unexpected Death in Epilepsy (SUDEP)

A death is referred to as SUDEP when a seemingly healthy person with epilepsy dies unexpectedly and no clear reason for the death can be determined. In most cases, an autopsy is required to rule out other causes of death. A widely accepted definition of SUDEP was proposed by Dr. Lina Nashef : “The sudden, unexpected, witnessed or unwitnessed, non-traumatic, and non-drowning death of patients with epilepsy with or without evidence of a seizure, excluding documented status epilepticus, and in whom post-mortem examination does not reveal a structural or toxicological cause for death.”

The most common criteria used to determine whether a death is due to SUDEP are:

• The person has epilepsy, which is defined as recurrent unprovoked seizures.
• The person died unexpectedly while in a reasonable state of health.
• La muerte se produjo repentinamente y durante una actividad normal (a menudo durante el sueño).
• An obvious medical cause of death could not be determined at autopsy.
• The death was not the direct result of status epilepticus.

Although there is no proven prevention for SUDEP, researchers, public health officials and advocates in the epilepsy community are working hard to change that. There are meaningful and proactive actions that patients and caregivers can take to reduce the risk of SUDEP. Those strategies include:

• Seeking maximum seizure control via strict treatment adherence;
• Engaging in regular physical activity and lifestyle modifications that reduce stress;
• Patients should regularly visit with their doctor, especially if their convulsive seizures are not completely controlled;
• Considerar la supervisión o monitorización durante las horas de sueño para identificar la actividad convulsiva;
  • Specifically, consider the use of resources such as monitoring devices that can alert caretakers to certain types of seizures and enable early intervention;
• Ensure that family members and caretakers have knowledge of seizure first aid and of emergency resuscitation measures including CPR and defibrillator use;

We also encourage patients and caregivers to inquire about and advocate for research that leads to more answers about the causes of SUDEP, and to advocate for increased SUDEP awareness by the public and the medical community.

An estimated 1 in 26 people will develop epilepsy over the course of a lifetime. All of them should be made aware of the risks that accompany epilepsy, including SUDEP. As is the goal with other diseases and conditions that can be fatal, SUDEP must be attacked, dissected, understood, and conquered. This requires increased funding for research and the brightest minds in medicine and technology leading this research.

Activity related to SUDEP research has gained momentum in recent years; SUDEP has become a more common topic at all levels of meetings among neurologists, epileptologists, and epilepsy organizations. For too long, the standard of non-disclosure around SUDEP has been the tragedy of omission, the tragedy of silence, the tragedy of passivity, one after the next. It is time for change.

Our Danny Did approach to making progress against SUDEP features these elements:

• Train and encourage doctors, nurses and all medical professionals to communicate about SUDEP with epilepsy patients and caregivers. Knowing about the risk is a critical first step.
• Empower epilepsy patients and their loved ones with education and resources to learn about SUDEP, and about ways to minimize the SUDEP risk.
• Partner with Partners Against Mortality in Epilepsy (PAME), the North American SUDEP Registry (NASR) and others to advance collaborative campaigns designed to combat epilepsy mortality.
• Seek out technologies and devices that serve as seizure detection and prediction systems for home use that enable intervention during a seizure; and enable access to these systems through family grants.
• Engage medical students and early career healthcare professionals so they understand the family perspective around the importance of SUDEP disclosure.
• Engage the medical examiner and coroner community to improve tracking around how often epilepsy-related deaths occur, to improve statistics that play role in funding for research.
• To address the need for better tracking of epilepsy deaths, the DDF worked with Illinois State Senator Dan Kotowski to pass the Danny Stanton SUDEP Act, which requires coroners and medical examiners in Illinois to report instances of SUDEP to the North American SUDEP Registry (NASR) at New York University.

Uncontrolled seizures and convulsive seizures at night present two of the greatest risk factors for SUDEP. It is important to talk with your doctor about your individual risk level, with the goal to create a treatment plan for the fewest possible number of seizures. Be sure to read our SUDEP FAQ page for more important information.

Solving the SUDEP riddle will be achieved only when specific risk factors are identified, and the exact mechanisms of death are determined. The Danny Did Foundation is committed to combatting SUDEP in honor of Danny Stanton and every family who has lost a loved one to epilepsy.
