What happens in the brain at the moment of death has fascinated doctors, philosophers, and ordinary people for centuries. Myths and religious traditions have long spoken of a “life review,” where your past flashes before your eyes. Modern science, for the first time, is beginning to catch glimpses of what really unfolds in the final minutes after the heart stops.
A widely discussed idea is that the brain may continue working for about seven minutes after death, potentially giving rise to vivid flashes of memory and awareness. Recent studies suggest this may not be just folklore.
In 2022, doctors in Canada made a startling discovery. They were monitoring an 87-year-old patient with epilepsy when he suddenly suffered cardiac arrest. As his heart stopped, the electroencephalogram (EEG) kept recording his brain activity. What they saw was astonishing: rhythmic brain waves that resembled those seen during memory recall, dreaming, or meditation.
The researchers noted surges in gamma oscillations, which are linked to conscious processing, learning, and memory retrieval. It was as if the man’s brain was playing back moments of his life in a final act of reflection. This provided the first direct evidence that the dying brain may remain active, even organized, after the heart has stopped.

The “seven minutes of life” theory emerged from similar findings. When the heart ceases to beat, blood flow to the brain stops, but neurons do not die immediately. Instead, they enter a state of frantic activity as they are starved of oxygen. During this short window, electrical surges ripple across the cortex, creating what some scientists describe as a last burst of consciousness .
Some neurologists believe this window could be responsible for the life-flashing-before-your-eyes phenomenon reported in near-death experiences. Memories may be triggered by abnormal synchronization of neurons, creating vivid, movie-like recollections.
The connection between this brain activity and near-death experiences (NDEs) is striking. Studies of cardiac arrest survivors show many report floating above their bodies, seeing tunnels of light, or meeting deceased loved ones. Others describe a panoramic replay of their life events, sometimes accompanied by feelings of peace and detachment.
Dr. Sam Parnia’s large-scale AWARE studies monitored hundreds of patients across multiple hospitals during cardiac arrest. While most did not survive, some who were revived reported precise details of events in the room while they were clinically dead, as well as intense memory flashbacks. These reports align with the idea that the brain, far from shutting down instantly, lingers in a state of heightened, unusual activity.
Neuroscientists suggest that this “last burst” could be explained by the physiology of dying neurons. As oxygen levels plummet, neurotransmitters like glutamate flood the brain. This overstimulates neurons, causing them to fire in abnormal, synchronized ways. Gamma oscillations may peak during this time, briefly sustaining complex conscious experiences.
In animal studies, rats that suffered cardiac arrest showed spikes of coherent brain activity within 30 seconds of death. Human data now confirm similar patterns. Although brief, this activity may be enough to produce vivid subjective experiences.
These findings raise profound questions. If the brain continues to generate conscious-like activity minutes after death, does this blur the boundary between life and death? Is the “life review” a final, natural brain function, or does it hint at something beyond?
While many scientists caution against overinterpreting the results, others see the possibility of bridging neuroscience and spirituality. The universality of near-death reports across cultures suggests there may be common biological mechanisms at work, yet their meaning remains open to interpretation.
Some traditions describe this as the soul’s transition, while neurologists see it as a natural byproduct of oxygen-starved neurons. Either way, the dying brain appears far from silent.
Traditionally, death was declared when the heart stopped beating. Today, medicine recognizes that death is a process rather than an instant. Brain activity may persist for minutes, and in rare cases of resuscitation, patients return with memories of those moments. This challenges both how we define death and how long doctors should wait before making the declaration.
Modern guidelines already recommend observing a patient for several minutes after cardiac arrest before pronouncing death. Discoveries about lingering brain activity add further weight to this caution.
Multivitamins are essentially dietary supplements containing a combination of various vitamins and minerals, often used to bridge nutritional gaps in the diet, treat deficiencies caused by poor nutrition or illness and support overall health.
Designed to provide a broad range of nutrients in one daily dose, they are available in tablets, capsules, gummies or liquids and are widely recommended to adults of all ages and genders.
But which vitamins do women need and when should you be taking them?
Dr Yashica Gudesar, Director & Unit Head of Obstetrics & Gynecology, Max Super Speciality Hospital, Dwarka exclusively tells Healthandme: "A woman’s nutritional needs change at different stages of life, from adolescence to reproductive years, pregnancy, and menopause. While food should always be the primary source of nutrients, certain vitamins may be required as women age or depending on lifestyle, diet, and health conditions."
"There’s honestly no universal vitamin checklist that works for every woman. The needs change with age, lifestyle, stress, whether one is planning a pregnancy, and of course, what the blood reports actually show," Bhakti Samant, Chief Dietician, Kokilaben Dhirubhai Ambani Hospital further told this publication.
Here are the supplements you need to stock your medicine cabinet with:
Vitamin D is a fat-soluble nutrient essential for strong bones, immune function, and calcium absorption, often synthesized when skin is exposed to sunlight or obtained via food and supplements.
Symptoms of Vitamin D deficiency include bone pain, muscle weakness, and depression. Deficiencies are common due to low sun exposure or poor diet, leading to rickets in children and osteomalacia or osteoporosis in adults.
However, this can be avoided by consuming a combination of calcium and Vitamin D supplements. Dr Ginni Kalra, Head Dietician, Aakash Healthcare explained to Healthandme: "One of the frequently deficient nutrients in women is vitamin D. It is very important in calcium absorption, bone density, immune homeostasis and mood balance. In most adult women, the amount needed is 600-800 IU (15-20 mcg) per day although deficient women can take 1000-2000 IU per day under the supervision.
"Calcium is necessary in bone density especially in women post-menopause who experience rapid bone loss owing to the diminishing estrogen. Adult women should take 1,000 mg per day that rises to 1200 mg past 50 years. Calcium supplements are most ideal in separated doses of 500-600 mg each time and preferably following meals. When combined with vitamin D, absorption will enhance much better."
"Calcium becomes especially important after the age of 30, and even more after menopause. It can be taken after meals, often divided into two doses for better absorption," Dr Gudesar added.
Moreover, Samant advised: "Vitamin D is best taken with a meal that has some fat. Calcium (around 1000–1200 mg daily) is better split into two doses and should not be taken with iron."
A vital mineral, iron plays a very crucial role in human functioning by helping create hemoglobin to transport oxygen throughout the body, essential for energy and muscle function. Low iron levels can result in decreased oxygen transport and leading to symptoms like extreme fatigue, weakness, pale skin, cold hands/feet and shortness of breath.
While an iron deficiency is usually caused by poor diet, blood loss due to menstrual periods, ulcers, cancer, or regular use of pain relievers like aspirin or malabsorption issues, it can be remedied through supplements.
Dr Kalra explains: "Iron is also essential especially in menstruating women because they lose blood monthly. It may result in an iron deficiency which causes fatigue, loss of hair, brittle nails, and poor concentration. The acceptable amount of iron that is recommended to be taken by women aged 19 to 50 is approximately 18 mg, but this reduces to 8 mg after menopause.
"Iron supplements are better absorbed on an empty stomach or when taken with vitamin C and not when they are taken with calcium, tea or coffee as they have been found to interfere with absorption. The intake in the morning is usually desirable, but in case of gastrointestinal discomfort, it should be avoided."
Vitamin C is essential for the body because it serves as a powerful antioxidant, supports the immune system, and is crucial for the synthesis of collagen, which is vital for wound healing and the maintenance of healthy skin, bones, and blood vessels.
It also enhances the absorption of iron from plant-based foods and protects cells from damage caused by free radicals, potentially reducing the risk of chronic diseases like cancer and heart conditions.
While, foods such as oranges, lemons, red and green peppers, kiwifruit, broccoli, strawberries, and Brussels sprouts can provide help maintain Vitamin C levels, supplements can help boost absorption and maximize benefits.
Dr Kalra notes: "Vitamin C helps to maintain the immunity, collagen synthesis, and iron uptake. It should be taken in 75 mg daily by adult women. It is soluble in water and can be consumed together with breakfast."
Additionally, she also recommends intaking: "Vitamin E and vitamin A also help the skin, vision, and antioxidant defense, but overconsumption is not advisable because it may be toxic."
Omega-3 fatty acids are polyunsaturated fats known for their crucial role in brain function and overall mental health. Fish oil is particularly rich in EPA and DHA, which are vital components of cell membranes and have strong anti-inflammatory effects in the body.
These omega-3s play a critical role in human development, and they are primarily found in fatty fish and fish oil. Some popular sources of Omega-3 include:
But as many people do not consume enough fish, supplementation is often recommended to ensure adequate intake of these essential fatty acids.
Dr Kalra suggests: "Though not vitamins, omega-3 fatty acids are worth mentioning because of the cardiovascular, hormonal, and anti-inflammatory effects. About 250–500 mg of combined EPA and DHA a day may be helpful and is most often administered after meals."
Symptoms of a Vitamin B12 deficiency often appear slowly. You may not notice them at first, or may blame them on stress, lack of sleep or a busy schedule. However, if the deficiency continues for long, it could lead to serious health problems.
Dr Gudesar recommends: "Vitamin B12 supports nerve health and energy levels. Vegetarian women are more prone to deficiency. It is typically taken in the morning."
"Vitamin B12 is needed to promote nerve well-being, red blood cell building, and energy conversion. The chances of deficiency are increased in vegetarian women because B12 is mostly found in foods of animal origin. The suggested daily dose is 2.4 mcg, but the dosage can be raised in deficiency. It is preferable in the morning as it could increase alertness," Dr Kalra explained.
However, Dr Kalra also advises: "There should be individualization of supplement timing and dosage. Decisions should be based on routine blood tests, dietary assessment, age, lifestyle, and existing medical conditions.
"Excessive supplementation is detrimental, in particular, fat-soluble vitamins. The only safe and effective approach is nutritional adequacy by means of whole foods, and supplements are the supportive therapy only in cases where deficiencies are observed."

The digital revolution has transformed childhood. From online classes to gaming and entertainment, headphones and earphones have become constant companions for children. While technology has brought convenience and learning opportunities, it has also introduced a silent threat, damage to children’s hearing.
In my clinical practice as an ENT surgeon, I am witnessing an alarming increase in young patients presenting with symptoms such as ear discomfort, ringing in the ears (tinnitus), and reduced hearing ability. These issues, once uncommon in children, are now becoming increasingly frequent due to excessive and unsafe use of personal audio devices.
What makes the situation more concerning is that children often do not recognize the early warning signs. By the time symptoms become noticeable, significant damage may have already occurred.
• Listen at no more than 60% of the maximum volume
• Limit usage to 60 minutes at a time, followed by a break
This simple guideline can significantly reduce the risk of hearing damage and should be strictly followed by children and adolescents.
• Frequently increasing the volume of devices
• Complaints of ringing, buzzing, or ear pain
• Difficulty in hearing conversations
• Speaking unusually loudly
If any of these symptoms are noticed, it is important to consult an ENT specialist promptly.
1. Limit Earphone Use: Encourage children to use speakers whenever possible instead of earphones.
2. Choose Safer Devices: Over-the-ear headphones are generally safer than in-ear earbuds as they reduce direct sound impact.
3. Ensure Quiet Environments: Avoid using headphones in noisy surroundings, as children tend to increase volume to compensate.
4. Take Regular Breaks: Continuous listening should be avoided. Short breaks help the ears recover.
5. Avoid Night-time Use: Using headphones before sleep can harm both hearing and sleep quality.
Routine hearing check-ups should also be encouraged, especially for children who frequently use headphones for study or entertainment.
The digital age is here to stay, and technology will continue to play a central role in children’s lives. However, safeguarding their health must remain a priority. Hearing is a precious sense that, once lost, cannot be restored.
By adopting simple precautions, spreading awareness, and encouraging responsible use of technology, we can ensure that our children enjoy the benefits of the digital world, without compromising their hearing health.

In a recent post, Dr Sudhir Kumar shared the case of a five-year-old Rishi, a seemingly healthy boy, who suddenly started showing symptoms of deafness and even vision loss. However, the problem wasn’t as surface level as it seemed, as the boy’s brain health was the root cause.
Dr Sudhir Kumar, a Bangalore-based neurologist, shared the rare neurological case of Landau-Kleffner syndrome, he encountered in a five-year-old on the social media platform X.
According to John Hopkins Medicine, Landau-Kleffner Syndrome is a rare nervous system disorder that can cause the loss of ability to understand and use language.
They explain that it can happen to a child who has been developing normally and can also cause seizures. It can happen over time or even suddenly.
But what causes it and is it treatable? The condition is treatable with speech therapy and medication; however, not much is known regarding what causes it.
Researchers say it could be caused by mutation in the genes or the immune system attacking its own tissues like an autoimmune disorder.
While the first 3 years of Rishi’s life was on track with the development of an average child, things quickly changed.
He stopped looking up when his name was called and acted as if he couldn't hear at all. His parents took him to ear specialists, but the tests showed his ears were perfectly healthy. Over the next year, Rishi stopped speaking entirely and was eventually labeled as "deaf and mute."
Dr Sudhir explained that the timeline of his symptoms didn't match typical deafness. Most children who can't hear are born that way; they don't usually start talking and then suddenly stop.
This suggested that Rishi hadn't lost his hearing, he had lost his ability to understand sound. To solve the mystery, the doctor ordered a sleep EEG to monitor Rishi’s brain waves overnight.
The symptoms of Landau-Kleffner Syndrome can be confusing because they often look like hearing loss or autism. Based on Rishi’s experience, the main signs include:
The most important takeaway for Rishi’s family was that LKS is treatable. Because it is caused by abnormal electrical activity, doctors can use anti-seizure medications to "calm" the brain. Once Rishi started his treatment, the results were life-changing.
After three months, he began responding to his name again. Within six months, he was talking, playing, and laughing just like any other child. The "silence" in his home was finally gone.
Rishi’s story is a reminder that when a child suddenly loses language skills, every second counts. If LKS is caught early, the brain has a much better chance of recovering and rewiring itself.
If left untreated for too long, the loss of speech could become permanent. By understanding that the problem was in the brain and not the ears, Rishi’s doctors were able to give him his future back.
