Near-Death Experiences and the Brain — A Psychiatrist’s Honest Take | Bharosa

He died for ninety seconds on the operating table. He saw a tunnel. He saw his grandfather, who had been gone for twenty years. He saw a light that he later struggled to describe to anyone in language that did not sound either ridiculous or religious. When the surgeons brought him back, they treated his body. Nobody asked him about the ninety seconds. He told his wife once and stopped, because the look on her face suggested he should not bring it up again. He has carried it for eight years.

He cannot decide whether what he experienced was real, hallucinated, divine, or simply his brain doing strange things on its way out. He has never asked a doctor, because he is not sure who he could ask.

If you or someone you love has had a near-death experience and is quietly struggling to make sense of it, this article is for you. At Bharosa, we believe people who have had these experiences deserve thoughtful, scientifically grounded, respectful conversation about them — not dismissal, not excessive enthusiasm, and certainly not silence. Near-death experiences sit at one of the most interesting intersections in modern neuroscience and psychiatry, and they deserve to be discussed honestly. Here is what the science actually says, and how a good psychiatrist approaches them.

What a Near-Death Experience Actually Is

Near-death experiences, often abbreviated as NDEs, are a recognised cluster of psychological events reported by people who have come close to death — most commonly during cardiac arrest, severe trauma, or surgical complications — and have been resuscitated. The experiences typically include some combination of feeling separated from the body, moving through a tunnel or void, seeing a bright light, encountering deceased relatives or beings of light, experiencing a life review, and in some cases reaching a perceived border or point of no return before being pulled back. The pattern is remarkably consistent across cultures, age groups, and religious backgrounds, which is part of what has made them scientifically interesting.

The Lancet, one of the most respected medical journals in the world, has published landmark prospective studies on near-death experiences in cardiac arrest survivors, documenting that a significant minority of patients who are clinically resuscitated report vivid, structured, often life-altering experiences during the period of clinical death. The National Institutes of Health, the largest biomedical research agency in the United States, has funded research into the neurobiology of near-death experiences, and the American Academy of Neurology, the leading professional body of neurologists, recognises NDEs as an active area of clinical and scientific inquiry.

What the Brain Is Actually Doing

The honest scientific answer is that we do not yet fully understand. What is known is that the dying brain undergoes a number of well-documented neurobiological changes — surges in neurotransmitter activity, electrical bursts in cortical regions, oxygen deprivation, and dramatic shifts in blood flow — that can produce the kinds of vivid, structured, emotionally powerful experiences that NDE survivors describe. Several neuroscience studies have shown that the dying brain is far more electrically active than previously assumed, with some studies documenting bursts of high-frequency brain activity in the moments around clinical death.

Different scientific frameworks attempt to explain the experience. Some focus on neurotransmitter systems, particularly the role of N-methyl-D-aspartate (NMDA) receptors and endogenous chemicals released under extreme stress. Others focus on temporal lobe activity, which is known to produce sensations of presence, déjà vu, and out-of-body experiences when stimulated. Others focus on the integration of memory and emotion in the dying brain. None of these explanations is yet complete, and reasonable scientists continue to debate the details. What is clear is that the experiences are not simply hallucinations in the dismissive sense of the word. They are vivid, structured, often deeply meaningful, and they leave lasting psychological imprints on the people who have them.

Why NDE Survivors Often Need Mental Health Support

Most people who have had a near-death experience describe it as transformative. Many report reduced fear of death, deeper appreciation for life, and a renewed sense of purpose. But the integration of the experience is not always easy. Survivors often face several specific challenges. Difficulty discussing the experience with friends and family who do not know how to respond. A sense of isolation, particularly if their religious or cultural community does not have language for what they experienced. Anxiety or depression as they try to reconcile the experience with their previous worldview. Sometimes, post-traumatic symptoms related to the medical event itself, separate from the NDE.

Many NDE survivors also describe feeling that ordinary life looks small after the experience, which can be both freeing and disorienting. Some struggle to return to old jobs, old relationships, or old goals that no longer feel meaningful. None of this means anything is wrong with them. It means they have had a profound experience that almost nobody around them knows how to discuss, and the integration is psychologically demanding work. A psychiatrist who takes the experience seriously, neither dismissing nor sensationalising it, can be enormously helpful.

How Bharosa Approaches NDE Patients

At Bharosa, our consultant MD Psychiatrists and clinical psychologists approach NDE survivors with respect for what they have experienced and clinical rigour in assessing their current mental state. We do not pathologise the experience itself. We do not insist on a particular interpretation. We listen, we assess for any underlying anxiety, depression, post-traumatic stress, or adjustment difficulty, and we treat what is treatable using evidence-based approaches including Cognitive Behavioural Therapy (CBT). Where the patient simply needs a thoughtful clinical conversation about what they experienced and how to integrate it, we provide that too.

If you have had a near-death experience and have been carrying it alone, you do not need to keep doing that. There is real, respectful, scientifically informed care available — and you are not the first person to walk into our outpatient department in LB Nagar to talk about it.
