Several medical conditions and states of lowered metabolic function or suspended animation can cause a person to appear dead. Profound unresponsiveness, lack of visible breathing, inability to feel the pulse, or total immobility are inadequate grounds to declare a person dead. Mistaken certification of death has “grave” consequences and amounts to “missing the forest for the trees”.
MEDICALLY DISTINCTIVE STATES
- Brain Death is the irreversible cessation of all brain function, including the brainstem, and is legally considered death.
- Unresponsive wakefulness syndrome (UWS) or Vegetative State (VS) involves a patient who is awake but not aware, with a functioning brain stem allowing for breathing and involuntary movements, spontaneous eye opening, and reflexive behaviours, but lacks purposeful movement, communication, or awareness of self and surroundings.
- Lazarus Syndrome refers to the rare, spontaneous return of circulation after failed resuscitation efforts, sometimes making a deceased person appear to “wake up”.
- Minimally Conscious State (MCS) patients display inconsistent but definite evidence of awareness by following simple commands or reaching for objects.
DEFINITION OF DEATH
The irreversible cessation of all brain functions, including the brainstem (irreversible cessation of circulatory and respiratory functions), is the official medical and legal standard for death (brain death).
- Brainstem death is decided by the absence of reflexes (pupil, corneal, oculocephalic or Doll’s eyes, oculovestibular or Cold caloric, gag and cough), and the apnoea test (no spontaneous respiratory movement despite a high carbon dioxide level of PCO2>20 mmHg over baseline or >60 mmHg, when removed from the ventilator).
- If clinical testing cannot be completed safely, imaging tests can confirm the lack of cerebral function (EEG) or blood flow (Cerebral Angiography).
- A ventilator maintains breathing, drugs/pacemaker keep the heart beating, and water and nutrition are provided through tubes to keep the body artificially alive after brain death.
- Clinical death is a transient state where the heart stops pumping blood and breathing stops, though it may be reversible on immediate resuscitation.
- Biological/ cellular death occurs shortly after clinical death, with permanent and irreversible cellular damage and cessation of metabolic activity.
- Mortality, fatality, casualty, and deceased are lay terms used for death.
BOARD OF MEDICAL EXPERTS TO CERTIFY BRAIN DEATH FOR ORGAN DONATION
In India, the board consists of four doctors, as mandated by the Transplantation of Human Organs & Tissues Act (THOTA), 1994, and its amendments. This certification of brain death must be done twice, with a minimum interval of 6 hours between the tests, and in Form 10. The team of experts consists of the following:
- Registered Medical Practitioner (RMP) in charge (medical administrator or superintendent) of the hospital where the patient is admitted.
- Neurologist or Neurosurgeon approved by the “Appropriate Authority” to perform the neurological examination. If an approved neurologist/neurosurgeon is not available, a surgeon, physician, or intensivist empanelled by the authority may be chosen.
- An independent doctor (RMP) nominated from a panel approved by the government/ appropriate authority, who is not involved in treating the patient or the transplant team.
- Treating Physician/Medical Officer in charge of the patient’s care in the ICU.
- The doctors certifying brain death cannot be part of the team involved in transplanting the organs, to ensure zero conflict of interest. At least two of the four doctors must be from a panel approved by the state government/appropriate authority. If the case is a medico-legal one (e.g., accident), a forensic expert or a doctor from a government hospital is required. The presence of a Transplant Coordinator (TC) is mandatory to assist in the process and obtain consent.
STATES THAT CAN BE CONFUSED FOR DEATH
Death-like states can confuse an inexperienced doctor into certifying death.
- Catalepsy is a nervous disorder characterized by a trance-like state, complete immobility, reduced sensitivity to pain, and significantly slowed breathing and circulation, lasting from minutes to weeks. •Locked-in Syndrome is when a fully conscious and awake person experiences near-total paralysis, unable to move or speak, although eye movement may be possible.
- Coma is a deep state of unarousable unresponsiveness where a person is alive but has no awareness, cannot move, open eyes, or respond to any stimulus. It is not the same as brain death or vegetative state.
- Extreme cold can cause hypothermia, drastically slowing the body’s metabolic functions, like in a hibernating animal. A person with severe hypothermia may have no palpable pulse or detectable breathing, appearing clinically dead, yet may sometimes be revived.
- Catatonia is a behavioural syndrome that can involve a lack of movement, responsiveness, and speech (stupor), sometimes accompanied by rigid muscles.
- High doses of certain depressants (e.g., opioids, sedatives) can lead to temporary unresponsiveness that mimics death. Severe hypotension, neuromuscular blockers, and metabolic intoxication must also be excluded.
- Postictal (following a seizure) state of temporary coma or profound unconsciousness can mimic death.
EUTHANASIA
It permits or assists death to relieve incurable suffering, as a matter of autonomy and dignity in death. •Passive Euthanasia (“letting die”) leads to death by withholding or withdrawing life-sustaining treatment, such as turning off a ventilator or stopping feeding tubes. It is legal in India under strict guidelines established by the Supreme Court, and in over 80 other countries. A designated medical board must review the patient’s condition, and approval from the relevant High Court is required. The Supreme Court permitted the first case of passive euthanasia in 2026 March, based on the Common Cause v. Union of India (2018) judgment.
- A living will is an advance medical directive, by an adult of sound mind, specifying against being kept alive by machines if in a vegetative state.
- Active Euthanasia “mercy killing” involves a person directly causing the patient’s death through the administration of a lethal injection of a three-drug cocktail of a sedative (midazolam or sodium thiopental) to induce unconsciousness, pancuronium bromide to cause paralysis, and potassium chloride to stop the heart. Active voluntary euthanasia is legally permitted in several countries and jurisdictions as of 2025-2026, including Belgium, Luxembourg, the Netherlands, Spain, Canada, Colombia, Ecuador, New Zealand, and Australia. Portugal and Uruguay have passed laws but are awaiting final regulations.
- Euthanasia is voluntary when a patient with full mental capacity makes a conscious and informed request to die. It is non-voluntary when the patient is unable to give consent (e.g., in a coma or severe vegetative state), so a decision is made on their behalf by family and doctors. It is involuntary when a person’s life is terminated against their will or without their consent, and is considered murder, unless performed as capital punishment (abolished in over 110 countries, legal in about 54 nations).
- Physician-Assisted Suicide is legal in Switzerland and certain US states. A doctor provides the means (medication) for the patient to end their own life, but does not directly administer it. The consenting patient must be a terminally ill adult with unbearable and irreversible pain.
THE TEAM OF EXPERTS REQUIRED TO SUPERVISE PASSIVE EUTHANASIA
It consists of a primary medical board (hospital level) and a secondary medical board (external).
- The Primary Medical Board is formed by the hospital where the patient is admitted, and must review the case and provide a preliminary opinion within 48 hours. It consists of the primary doctor responsible for the patient’s care, and at least two subject experts – physicians with at least 5 years of experience in the relevant specialities (e.g., neurology, nephrology, cardiology, oncology, onco-anaesthesia, palliative medicine, and psychiatry).
- If the primary board approves the withdrawal of life support, an external Secondary Medical Board is constituted to provide an independent review within 48 hours. It consists of a medical officer nominated by the district chief medical officer (CMO) and two specialists who were not part of the primary medical board.
- The experts evaluate if continuing treatment is futile and burdensome, rather than simply letting the patient die with dignity. The board must consult with the patient’s next of kin/guardian and document the decision in writing, and report it to the Judicial Magistrate of First Class (JMFC), and any Living Will must be attested by a notary or gazetted officer.
Organs can only be taken from individuals who are brain dead, ensuring that organ retrieval does not itself cause death. Organ donation consent can be given by the individual or, in the case of minors or deceased donation, by their next of kin, such as parents, spouses, or close relatives. Even if a person has pledged their organs (donor card or registration), the family’s final consent is mandatory under Indian law. If a postmortem is required, organs not linked to the cause of death can be donated with family permission. Unlike organ donation, euthanasia does not require brain death and is a conscious choice or a medical decision in cases of unbearable suffering, and is rooted in autonomy, dignity, and the right to die.
