What happens when a person is about to die?

The patient gradually becomes tired, sleeps more, and may enter a peaceful dream state.

Whether you like it or not, death is something we cannot avoid. It's an important part of life and something everyone will experience one day.

This process can seem scary, because we don't know what will happen to us.

Dr. Kathryn Mannix specializes in end-of-life care, describing it as a process: “In my opinion, death is probably not as bad as you think.”

“Death, like birth, is a process. Gradually people become tired and sluggish. As time passes, people sleep more and stay awake less."

The author of With The End in Mind, shared his thoughts in a short film for BBC Ideas.

She wants to break down fears and encourage people to talk about what happens when someone is dying.

Dr. Thomas Fleischmann shares about the stages of death, after witnessing nearly 2,000 people pass away.

"In the first stage there is a sudden change, all pain disappears. Anxiety, fear, noise are all gone. Only peace and quiet remain. Some feel joy. ”.

The second stage is an "out of body experience", the third stage is a feeling of "comfort" for nearly everyone.

However, some people still describe feeling "terrible noises, unpleasant smells and scary creatures".

In the fourth stage, the patient often sees light beginning to shine into the dark night.

According to Dr. Fleischmann, people who are about to die report seeing “beautiful surroundings, bright colors, some hear moving music and a feeling of unconditional love” – which is fifth stage.

Research published earlier this year suggests the process may be more pleasant than we think.

Scientists have accidentally captured the brain - the most complex organ in the body - at a standstill, revealing the astonishing moment of death.

A patient with epilepsy was hooked up to an electroencephalogram (EEG) before his heart attack, recorded 15 minutes before his death.

During the 30 seconds around the patient's last heartbeat, experts noticed a very specific increase in brain waves.

These waves, called gamma oscillations, are associated with factors such as memory retrieval, meditation and dreaming.

This shows that we can recall our best memories when we are about to die. However, more research is still needed.

The parts of the brain activated in this study also noted our ability to enter a peaceful dream state, a feeling similar to meditation.

stillAmerican scientists noted increased activity in the brains of dying people, as if they were awake, even after they stopped breathing.

Experiencenear death is a famous phenomenon that has not been properly explained by science.

Many people who "returned" from the dead recounted their unusual experiences. They see light at the end of the tunnel, others describe the feeling of "soul leaving the body", floating outside the body. Many people say they see their whole life flash before their eyes like a movie.

Researchers at the University of Michigan (USA) found evidence of increased brain activity related to consciousness in two patients.dying, explaining human near-death experiences.

The article was published on May 1 in the Proceedings of the National Academy of Sciences (PNAS), USA.

Although not the first study on the near-death phenomenon, this study is different because it is detailed in a way "that has never been done before", Dr. Jimo Borjigin confirmed to AFP News Agency.

"This is also probably the first study to really show how the brain dies every second," she added.

The research team monitored the EEG of four patients who died from the diseaseHeart stop. They were removed from life support after it was determined no further medical intervention was possible.

When removed from the ventilator, two of the four patients - a 24-year-old woman and a 77-year-old woman - were noted to have increased heart rates as well as increased brain waves at gamma frequencies. This is the fastest brain activity and is related to consciousness.

When testing which areas of the brain lit up, the team found activity in the "hot zone" of the posterior cerebral cortex, which includes the temporal lobe, parietal lobe and occipital lobe.

"If this part of the brain lights up, it means the patient is seeing something, can hear something, and can feel sensations outside the body," Dr. Borjigin said, concurring. He added that the area was "on fire".

The results of the analysis were reinforced by monitoring the brain and heart activity every second until the patient died.

However, Ms. Borjirin said it is unclear why the other two patients did not have similar signs. She speculated that the seizure history of the two female patients who had near-death experiences contributed to their brain stimulation.

It is also impossible to confirm whether the patients actually "saw" anything because they were not alive to tell the story.

In the future, Ms. Borjigin hopes to collect data on hundreds more people, increasing the chances that a few patients will "live" to recount the experienc
