What is the percentage of surviving a coma?

Survival rates from a coma vary greatly but are often poor, with studies showing death or severe disability in over 60% of patients, especially in non-traumatic cases, though traumatic brain injury (TBI) survivors have better recovery rates (around 80% regain consciousness). Key factors influencing survival include the cause (e.g., hypoxia, TBI vs. cerebrovascular issues), initial Glasgow Coma Scale (GCS) score, and brainstem reflexes, with low scores indicating much higher mortality risk.

What's the chance 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.

How long is the average coma?

There's no single "average" coma length, as it varies greatly from hours to months or even years, though many last a few weeks; recovery depends on the cause (like head injury, infection, diabetic issues) and severity, with some patients recovering fully, others transitioning to vegetative states, and some unfortunately dying. While shorter comas (days to weeks) are common, severe cases can be prolonged, with outcomes unpredictable but influenced by the degree of brain damage, age, and prompt care.
 

What is the life expectancy of a person in a coma?

Someone can survive a coma from days to several years, though most last a few weeks, with recovery depending heavily on the cause and severity of brain injury; many eventually wake up, while others transition to a vegetative state, and some may never regain consciousness, highlighting the importance of intensive medical care for survival and managing complications. 

Are you still alive if you are in a coma?

A coma, sometimes also called persistent vegetative state, is a profound or deep state of unconsciousness. Persistent vegetative state is not brain-death. An individual in a state of coma is alive but unable to move or respond to his or her environment.

What Happens in the Brain During a Coma?

Is being in a coma close to death?

Although many people gradually recover from a coma, others enter a persistent vegetative state or die. Some people who recover from a coma end up with major or minor disabilities. During a coma, bedsores, urinary tract infections, blood clots in the legs and other problems may develop.

How long will comas last?

A coma's duration varies widely, from a few days to months or even years, but typically lasts a few weeks, depending heavily on the cause and severity of the brain injury; some patients recover fully, others transition to vegetative or minimally conscious states, while some may not wake up, highlighting the unpredictable nature of recovery. 

Is a coma a near death experience?

NDEs can be experienced in a variety of states: coma, anaesthesia, syncope or even orgasm.

What is the longest a coma has lasted?

The longest coma on record, according to Guinness World Records, belongs to Edwarda O'Bara, who remained in a diabetic coma for about 42 years, from 1970 until her death in 2012, though Elaine Esposito held the record previously with 37 years. While O'Bara's case is the longest documented coma, Aruna Shanbaug also spent over 40 years in a persistent vegetative state after an assault. 

Can a person in coma yawn?

Yes, people in a coma or, more commonly, a related state like a vegetative state, can yawn, as it's a brainstem reflex, not a sign of awareness, showing basic autonomic functions like breathing, swallowing, and eye-opening continue despite unconsciousness. While a true coma involves closed eyes and depressed reflexes, a vegetative state involves open eyes and sleep-wake cycles, with yawning being a key indicator of preserved brainstem function without conscious thought. 

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. 

Is a coma like a long sleep?

Coma is a state of consciousness that is similar to deep sleep, except no amount of external stimuli (such as sounds or sensations) can prompt the brain to become awake and alert. A coma is a medical emergency.

What's the shortest a coma can last?

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. 

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.

Can brain damage be reversed?

Brain damage reversal is complex, with primary injury often irreversible, but the brain's neuroplasticity allows surviving neurons to reorganize and form new connections, potentially restoring function through therapies like rehab, specialized implants, or even certain nutrients, though some damage from stroke or substance abuse can be reversed or significantly improved. Treatment focuses on promoting natural repair, managing secondary damage, and regaining lost abilities through rehabilitation and emerging technologies, not typically "undoing" the initial physical damage.
 

How long will a hospital keep someone on life support?

Hospitals can keep someone on life support for varying lengths—from days to months or even years—depending on the underlying condition and potential for recovery, with decisions often made collaboratively by medical teams, patients (via advance directives), and families when recovery seems unlikely or prolonged support isn't beneficial, as there's no set time limit, but rather a focus on meaningful recovery or quality of life. 

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. 

Do people dream in a coma?

It's complex, but generally, people in deep comas don't dream due to lack of brain activity, but those in lighter states or medically induced comas often experience vivid, dream-like hallucinations, sometimes incorporating real-world sounds or sensations (like ice packs) into elaborate narratives, as the brain tries to process stimuli or cope, leading to confused "dreams" upon waking. 

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.
 

What did people who temporarily died see?

People who have had near-death experiences (NDEs) often report seeing bright lights, tunnels, deceased relatives, or having out-of-body sensations, accompanied by feelings of profound peace, love, or sometimes terror in hellish experiences, with common elements including life reviews and encounters with divine or familiar beings, though experiences vary greatly and some report seeing nothing at all. 

Can people on life support hear you?

Yes, studies and anecdotal evidence strongly suggest that people on life support, even when unresponsive or unconscious, can often still hear and process sounds, with hearing being one of the last senses to fade as someone dies. Brain activity in dying patients shows responses to familiar voices, suggesting that talking to loved ones, even when they can't respond, can be comforting and meaningful, so healthcare providers and families are encouraged to continue communicating.
 

What are the three signs of brain death?

The three core signs of brain death are a persistent coma (unresponsiveness), the absence of brainstem reflexes (like pupils reacting to light, gag, or cough), and the inability to breathe independently (apnea), requiring a ventilator to sustain life, all of which are irreversible and confirm the complete cessation of brain function. 

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. 

How do coma patients eat?

Coma patients cannot eat normally and receive nutrition through feeding tubes, delivering specially formulated liquid formula directly to their stomach or intestines via the nose (nasogastric/nasojejunal), or sometimes directly into the stomach through the abdominal wall (gastrostomy/PEG tube) for long-term feeding, bypassing chewing and swallowing. This process, called enteral nutrition, provides essential fluids, calories, protein, and vitamins, managed by dietitians, while intravenous (IV) fluids handle hydration and medications if needed.
 

Can a child go into a coma?

Children may spend some time in coma: perhaps a couple of days or perhaps many weeks. Some children will move from this level to a 'vegetative state'.
