Are you aware of time passing in a coma?
In a true, or non-induced coma, there’s no evidence of fluctuating circadian cycles or changing brain activity, according to Proekt. However, a person’s brain could spend time in more active states while coming into or out of the induced coma, just like when people go under anesthesia.
How long does it take for a person in a coma to die?
| Coma | |
|---|---|
| Specialty | Neurology, psychiatry |
| Symptoms | Unconsciousness |
| Complications | Persistent vegetative state, death |
| Duration | Can vary from a few days to several years (longest recorded is 42 years) |
Do coma patients feel anything?
People in a coma are completely unresponsive. They do not move, do not react to light or sound and cannot feel pain. Their eyes are closed. The brain responds to extreme trauma by effectively ‘shutting down’.
How long can you be in a coma without dying?
A coma often lasts for a few days or weeks. Rarely, it can last for several years. If a person enters a coma, this is a medical emergency. Rapid action may be needed to preserve life and brain function.
Can people in comas hear?
When people are in comas, they are unconscious and cannot communicate with their environment. However, the brain of a coma patient may continue to work. It might “hear” the sounds in the environment, like the footsteps of someone approaching or the voice of a person speaking.
Can coma patients cry?

How do doctors diagnose a coma?
Doctors normally order a series of blood tests and a brain scan to try to determine what’s causing the coma so that proper treatment can begin. A coma seldom lasts longer than several weeks. People who are unconscious for a longer time might transition to a persistent vegetative state or brain death.
What happens to a brain-dead person in a coma?
If an autopsy is done on a brain-dead patient, many cells of the brain will have wasted away. Because of the severe prognosis of these conditions, neurologists hope to find a sign that their patient may actually not be in a true coma or vegetative state, but rather in a minimally conscious state.
How many people are fully conscious in a coma?
Scientists now believe that 15 to 20 percent of people in a so-called vegetative state may be fully conscious. Advances in technology mean that we are better able to understand what people are experiencing during a coma.
