When the dead rise—but not really: Mistaken death diagnoses and the neurologist’s role in avoiding them

Stories of patients “coming back to life” after being declared dead have long captivated the public imagination—and terrified physicians. Although many of these accounts turn out to be exaggerations or misinterpretations, mistaken death diagnoses do happen, even in modern hospitals. For neurologists, who often oversee end-of-life assessments, particularly in comatose or brain-injured patients, these errors can have devastating consequences: ethical, legal, and emotional.

This blog entry explores how mistaken declarations of death occur, how to prevent them, and why neurologists must play a leading role in upholding diagnostic rigor when life and death hang in the balance.

Modern cases of “resurrection”

Although rare, documented cases of premature death declarations continue to surface:

• 2020, Detroit: A 20-year-old woman was declared dead by paramedics after a cardiac arrest. Hours later, she was found breathing at the funeral home. She had not met neurologic criteria for death and had been presumed dead solely on clinical grounds without hospital confirmation.
• 2023, Ecuador: A 76-year-old woman “woke up” in her coffin during her wake after being declared dead at a hospital. She had reportedly suffered a stroke and was presumed to have died when she stopped responding.

Such cases often reflect failure to follow standardized protocols, premature judgments under time pressure, or misinterpretation of reflexes and agonal movements.

The misdiagnosis of death

Death may seem self-evident, but neurologists know better. In many cases—especially in the ICU, after resuscitation, or in the setting of CNS injury—what appears to be death may actually be:

• Profound coma with preserved brainstem function
• Postictal unresponsiveness
• Severe hypothermia
• Drug intoxication or sedation
• Catatonia or locked-in syndrome
• Delayed return of spontaneous circulation (ROSC)

Neurologists must resist assumptions and rely on formal criteria—whether for brain death or circulatory death—before declaring life has ended.

Common errors in death determination

1. Skipping apnea testing in brain death evaluation. Without documented apnea testing (or valid ancillary studies), brain death cannot be declared—even in the absence of all reflexes.
2. Failure to rule out confounders. Hypothermia, paralytics, sedatives, or severe metabolic abnormalities can mimic brain death or coma.
3. Failure to recognize spinally mediated movements. In this instance, the error is to rule out brain death because of the failure to recognize that agonal gasps, spontaneous movements, or Lazarus signs are spinally mediated and do not refute properly diagnosed brain death.
4. Premature declarations after failed resuscitation. Post-cardiac arrest patients should be observed for at least several minutes before confirming the absence of spontaneous circulation.

The neurologist’s responsibility

Neurologists are uniquely positioned to lead and enforce death determination protocols, particularly when the diagnosis hinges on brain-based criteria. This role includes:

• Conducting or supervising formal brain death examinations
• Educating other clinicians about apnea testing, confounders, and confirmatory tests
• Advocating for proper waiting periods post-resuscitation
• Participating in hospital policy development and ethics committees

Institutions with formalized neurologic death protocols have significantly lower rates of misdiagnosis and higher staff confidence.

Communicating with families and the public

Mistaken death declarations erode trust in medicine. Transparent communication is essential, especially when:

• Brain death is being declared, but the patient still appears to "breathe" (eg, via a ventilator).
• Reflexive movements occur after death is certified.
• Ancillary testing is used to confirm a lack of cerebral perfusion or electrical activity.

Explaining that “life support” is not evidence of life—and that brain death is not reversible—can help families accept the finality of the diagnosis.

Conclusion

Mistaking a living patient for dead is among the gravest errors in medicine. As specialists in disorders of consciousness and brain function, neurologists must take responsibility for precision, protocol adherence, and education in death determination. Our credibility, and our patients’ dignity, depend on it.
