What do you see in a coma?

In a coma, a person appears deeply asleep but is unresponsive, with closed eyes and no voluntary movement, though reflexes and basic functions like breathing (sometimes irregular) remain; they experience no conscious awareness or dreaming like normal sleep, but some report vivid hallucinations or false memories as their brain tries to process external stimuli, making it a state of prolonged unconsciousness, not just deep sleep.

What do you see if you're in a coma?

The symptoms of a coma commonly include: Closed eyes. Depressed brainstem reflexes, such as pupils not responding to light. No responses of limbs except for reflex movements.

Do you experience anything in a coma?

While a deep coma means a person can't consciously feel or react, recent research suggests many remain partly aware, potentially experiencing sensations, emotions (like pain or pleasure), or even vivid dreams, though they can't communicate it; brain activity shows some unconscious people can process information, but deeper comas involve disrupted awareness networks, making true conscious feeling unlikely, yet some report profound experiences after waking. 

Do you dream while in a coma?

Yes, people in a coma can experience vivid, dream-like states, often described as living another life or having hallucinations, where they process their real-world experiences like hospital sounds and sensations, though these aren't always typical dreams with normal sleep cycles; many survivors report these surreal experiences, sometimes mixing reality with imagined scenarios, like dreaming of Alaska because of ice packs used for fever. 

Are you aware while in a coma?

In a true coma, a person is deeply unconscious, unaware, and unresponsive, appearing to be in a deep sleep but unable to be woken, but recent research shows some individuals thought to be in comas or vegetative states (disorders of consciousness) actually show brain activity indicating hidden awareness, meaning they might be conscious but unable to communicate. These patients can process information and might even feel sensations, a condition known as cognitive-motor dissociation, a surprising discovery that changes how we view these deep unconscious states, according to studies in The New England Journal of Medicine and Everyday Health*. 

What Happens in the Brain During a Coma?

Can a coma patient see?

In a typical coma, people can't see because their eyes are closed and they're unaware, but brain activity varies; some might have fleeting awareness, process sounds, or even have visions, while others experience deep unconsciousness, with "eyes-open" states like the vegetative or minimally conscious state showing varied perception, sometimes tracking objects or responding inconsistently.
 

What do people in coma think?

A coma happens when you're unconscious, unresponsive and unaware of what's going on around you. You can't wake up, think, talk, respond to a conversation or react to the feeling of pain.

What's the longest coma ever?

The longest coma ever recorded was held by Elaine Esposito, who remained in a coma for 37 years and 111 days, from 1941 until her death in 1978, after complications from an appendectomy as a child. While her case was the record for decades, another woman, Edwarda O'Bara, later surpassed it, spending over 42 years in a diabetic coma from 1970 until her death in 2012, according to Guinness World Records.
 

How long does a coma last?

A coma's duration varies greatly, from hours or days (especially for medically induced ones or brief incidents) to weeks (most common, 2-4 weeks), or even months or years in severe cases, depending on the brain injury's cause and severity, with outcomes ranging from full recovery to persistent vegetative states or worse. While many recover within weeks, longer comas generally mean a poorer prognosis, but it's hard to predict. 

Is being in a coma like sleeping?

No, being in a coma isn't like normal sleeping; while a person in a coma looks like they're deeply asleep, they are in a prolonged state of unconsciousness, unable to wake up or respond to stimuli, including pain, and their brain activity is significantly different, lacking the regular cycles of sleep. A coma involves a serious brain issue, unlike sleep, where the brain cycles through stages, processes information, and dreams, whereas a comatose brain has reduced activity and doesn't experience normal sleep patterns.
 

What are the odds of surviving a coma?

In patients with a scale from 5 to 7, 53% will die or remain in a vegetative state, while 34% will have a moderate disability and/or good recovery. In patients with a Glasgow Coma Scale of 8 to 10, 27% will die or remain in a coma, while 68% will have a moderate disability and/or good recovery.

What is your brain doing while you are in a coma?

In a coma, a patient is alive and there is some brain activity. Depending on the severity of the injury, recovery time varies and comas can be temporary or permanent. Patients in a coma might have brain stem responses, spontaneous breathing and/or non-purposeful motor responses.

Is a coma peaceful?

A person in a coma may become restless, requiring care to prevent them from hurting themselves or attempting to pull on tubes or dressings. In these instances, medicine may be given to calm the patient. Side rails on the bed should be kept up to prevent the patient from falling.

What is brain dead vs. coma?

Brain death is the irreversible, complete loss of all brain and brainstem function, meaning the person is legally and medically dead, with no chance of recovery, while a coma is a state of deep unconsciousness where the person is alive, has some brain activity, and may potentially recover, progress to a vegetative state, or eventually, brain death. The key difference is reversibility and presence of brain function: comas involve some function and potential, whereas brain death involves zero function and is permanent.
 

What is the shortest a coma can be?

A coma can be very short, lasting just minutes or hours, especially for milder brain injuries or when medically induced for a brief period, but most naturally occurring comas last days to a few weeks, with outcomes depending heavily on the cause and severity of brain damage. While some come out quickly, others progress to vegetative states or have lasting disabilities, making duration highly variable, though longer than a few weeks is less common for recovery, according to this Headway article and this Synapse article. 

What does a person look like in a coma?

A coma looks like a person in a deep, unresponsive sleep, with eyes closed and no response to sound, touch, or pain, though they may have irregular breathing or reflex movements. They can't be woken up, even though their body functions (like breathing and circulation) are often maintained, sometimes with medical help like ventilators, and they appear to be "asleep" but are unaware.
 

What does a coma feel like?

A coma feels like a profound, dreamless void, a complete absence of consciousness, awareness, and voluntary movement, often described as being "blackout drunk" or in "deep sleep without dreams," with no perception of time or surroundings, though some report faint awareness or sounds, and others experience sensations like pain or pleasure despite being unconscious. It's a medical state of deep unconsciousness, not normal sleep, where the brain's activity is greatly reduced. 

What is the deepest level of coma?

An individual who cannot respond to any aspects of the environment, even a painful stimulus, is considered to be in the deepest coma. An individual who can open eyes to command, or attempt to speak is at the upper limit of the comatose scale. GCS scares range from 3 [the most severe] to 15 [the least severe].

How long will a hospital leave you in a coma?

Hospitals keep people in a coma (induced or natural) for as long as medically necessary, ranging from hours to weeks, but often only a few days for medically induced cases to rest the brain, with recovery or transition to other states (like vegetative) happening over days, weeks, or months, depending heavily on the cause and severity of the brain injury. While many comas resolve, prolonged unresponsiveness can become a persistent vegetative state or lead to death, with some severe cases lasting years. 

Can a coma be reversed?

Yes, a coma can be reversible, especially if the underlying cause is identified and treated quickly, with outcomes ranging from full recovery to permanent disability or even death, depending on the cause, severity, and duration, as some causes like low blood sugar are easily fixed while severe brain trauma is less so. Recovery is often gradual, and many people transition from coma to other states like minimally conscious states, with many regaining full awareness over time, though comas rarely last more than a few weeks. 

Can you hear while in a coma?

Yes, people in a coma can often hear, even if they can't respond, and familiar voices, like loved ones, can create significant brain activity, suggesting auditory processing occurs and can even aid recovery, according to studies showing brain scans light up for close relatives and recorded stories helping patients regain awareness. While a coma means unconsciousness, the hearing sense is often the last to shut down, so speaking to them is encouraged as it provides comfort and may stimulate healing, though comprehension isn't guaranteed.
 

How long are you allowed to stay in a coma?

A coma's duration varies greatly, from hours to days, weeks, months, or even years, depending on the underlying cause and severity of brain injury, with most lasting a few weeks, but some prolonged cases extending for decades, like Elaine Esposito's record of over 37 years. While many recover consciousness, others transition to vegetative or minimally conscious states, or face poor outcomes, making recovery unpredictable. 

Is a coma a form of sleep?

No, a coma is not like sleep; while a person in a coma looks like they're sleeping deeply, they are in a prolonged state of unconsciousness and cannot be woken up by any stimulation, unlike someone who is merely sleeping, even deeply. Coma involves profound brain dysfunction from injury or illness, whereas sleep is a normal, cyclical state with distinct brain activity, including REM, that can be interrupted, notes Stanford Health Care, KidsHealth, and Better Health Channel.
 

Are people in comas in pain?

People in a coma are completely unresponsive. They do not move, do not react to light or sound and cannot feel pain.

Has anyone woken up from a coma after years?

Annie Shapiro (1913–2003) was a Canadian apron shop owner who was in a coma for 29 years because of a massive stroke and suddenly awakened in 1992.
