The Supreme Court of India is reviewing brain death certification amid allegations of misuse to facilitate organ harvesting and lack of standardised medical testing.
- The Supreme Court is seeking expert opinion from All India Institute of Medical Sciences on adding confirmatory tests such as electroencephalogram (EEG) and angiogram.

What is Brain Death?
- Brain death OR brain stem death is the irreversible cessation of all brain activity, including vital functions like breathing.
- Condition:
- No brainstem reflexes (pupil, gag, pain response)
- No spontaneous breathing (apnea)
- Patient survives only on ventilator support
- Need for Declaration:
- Essential for deceased organ donation (heart, lungs, liver, kidneys)
- Avoids risk to living donors
- Provides legal clarity for withdrawal of life support
About Electroencephalogram (EEG)
- An EEG is a non-invasive diagnostic test that records the brain’s electrical activity to assess functional status and detect abnormalities.
- Instruments Used:
- Surface electrodes placed on the scalp
- Amplifier to enhance electrical signals
- Computer system for recording and interpretation
- Procedure : Electrodes capture neuronal electrical impulses, producing wave patterns (alpha, beta, delta) for clinical analysis.
- Key Indications:
- Confirmation of brain death in absence of electrical activity
- Diagnosis of epilepsy and seizure disorders
- Assessment of coma, encephalopathy, and brain injuries
- Limitations:
- Can be affected by external interference
- May not conclusively establish brain death without clinical correlation
About Angiogram
- An angiogram is an imaging technique used to visualise blood vessels and assess blood flow, especially in the brain.
- Instruments Used:
- Contrast dye (radiopaque substance)
- Catheter inserted into blood vessels
- X-ray or fluoroscopy imaging system
- Procedure: Contrast dye is injected into arteries, and real-time imaging tracks blood flow to detect blockages or absence of circulation.
- Key Indications:
- Confirmation of brain death in absence of cerebral blood flow.
- Detection of vascular abnormalities (aneurysm, stroke, blockage)
- Evaluation before neurosurgical procedures
- Limitations:
- Invasive procedure with risk of complications
- Requires specialised infrastructure and expertise

Current Protocol in India for Brain Death Declaration
- Legal Basis: Governed under the Transplantation of Human Organs and Tissues Act (THOTA), 1994, recognizes brain stem death as legal death.
- Medical Board: It can only be declared by a 4-member panel including a doctor-in-charge, neurologist/neurosurgeon, treating physician and an independent doctor.
- Repeated Certification: Brain death must be confirmed twice (6–12 hours apart)
- Clinical Tests: Bedside tests (apnea test, brainstem reflexes) there is no mandatory requirement for EEG and angiogram.
Challenges in Brain Death Declaration
- Lack of Training & Awareness: Many doctors lack formal training in certification and there is no uniform curriculum in teaching hospitals
- Subjectivity in Testing: Apnea test may be inconsistently applied as videography mandate is often not followed
- Infrastructure Constraints: Advanced tests (EEG, angiogram) are unavailable in smaller hospitals
- This could reduce already low organ donation rates
- Ethical & Trust Deficit: Allegations of premature declaration for organ harvesting.
- Public mistrust affects consent for donation

Conclusion
Strengthening transparency, training, and standardised protocols is essential to ensure ethical brain death certification while boosting India’s organ donation ecosystem.
