Why can't you wake up from a coma?

People can't wake up from comas because severe brain injury or illness disrupts the brain's arousal system (the reticular activating system) and communication between brain regions, leaving the brain in a deep, unresponsive unconsciousness where it can't process external stimuli like pain or sound, even though the person is alive and may have basic reflexes. The brain's networks are too damaged or quiet to allow for consciousness, self-awareness, or voluntary action, preventing a return to wakefulness until the underlying problem resolves or the brain heals, which can take time or not happen at all.

What is the longest time someone has been in a coma and woke up?

The longest documented case of someone waking from a coma is Munira Abdulla, who regained consciousness in 2018 after being in a vegetative state for 27 years following a 1991 car crash, though some reports mention cases potentially lasting longer, like one person in the 1970s to 2012 (42 years), highlighting rare, extraordinary recoveries from profound unconsciousness, often with some level of function returning.
 

How are people in coma kept alive?

Coma patients are kept alive through intensive supportive care, primarily by managing breathing with ventilators, providing nutrition and fluids via feeding tubes (gastric tubes), and preventing complications like infections and bedsores through regular turning, skin care, and range-of-motion exercises, while treating the underlying cause of the coma (like brain swelling or bleeding) to stabilize the patient.
 

How long can someone be in a coma before they wake up?

Someone can wake from a coma in days, weeks, or even years, though most recover within a few weeks; recovery length varies widely depending on the cause (like trauma vs. stroke), severity of brain injury, age, and medical care, with some rare cases seeing remarkable awakenings after decades, while others never regain consciousness or transition to different states like vegetative or minimally conscious states.
 

Can people in a coma still hear you?

Yes, people in a coma can often still hear you, even if they can't respond; brain scans show activity, especially to familiar voices, and some patients recall hearing loved ones, suggesting that talking to them provides comfort and may aid recovery, as hearing is often the last sense to go. While comprehension varies, auditory pathways in the brain often remain active, making communication beneficial.
 

What Happens in the Brain During a Coma?

Do you dream in a coma?

Yes, many people in comas, especially those emerging from them or in medically induced states, report vivid, dream-like experiences or hallucinations, though they aren't typical dreams as they lack normal sleep cycles and can blend with reality, often incorporating hospital surroundings, medications, or sensory input like ice packs. While a true, deep coma usually prevents normal dreaming, the brain can create intense internal worlds, sometimes as nightmares or elaborate narratives, as it tries to process stimuli or heal.
 

Can someone in a coma cry?

Yes, people in a coma or similar states (like vegetative or minimally conscious states) can sometimes cry, laugh, or make facial expressions, but these are often reflexive, automatic responses from lower brain centers, not necessarily a sign of conscious emotional understanding or voluntary action, though they can be distressing for family. While a person in a deep coma is unresponsive, these reflex-like emotional expressions can occur as the brain slowly begins to show reactions, sometimes in minimally conscious states where some awareness might be present.
 

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. 

What happens if a coma patient doesn't wake up?

If you don't wake up from a coma, you might transition into a vegetative state (persistent or permanent), a minimally conscious state, or experience brain death, with the outcome depending heavily on the severity of the brain injury, its location, and duration, often leading to severe disability, long-term dependency, or death from complications like infections. While most comas are short, prolonged unconsciousness typically means a shift to other states where the body functions but consciousness is lost, or irreversible brain function loss occurs. 

How does it feel to be in coma?

Being in a coma feels like nothing, as it's a state of deep unconsciousness, unawareness, and unresponsiveness, similar to a profound sleep where you can't feel pain, hear, see, or move voluntarily, though some basic reflexes and brain activity remain, and a few people report fleeting memories or dreams, but generally, it's a blank slate where you're simply not "there".
 

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.
 

How expensive is it to keep someone alive in a coma?

Keeping someone in a coma alive is extremely expensive, ranging from thousands to tens of thousands of dollars daily in acute care (ICU), depending on life support, with estimates varying from $1,500 for ventilation to $7,500+ per day, plus potential long-term costs of $90,000+ annually for nursing homes or home care, totaling potentially millions over time for severe traumatic brain injuries or long-term vegetative states. Costs depend heavily on the level of care (mechanical ventilation, feeding tubes, 24/7 monitoring) and location (hospital vs. long-term facility). 

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.
 

Do you still get your period in a coma?

Yes, a person in a coma might still get their period because basic bodily functions like menstruation can continue via spinal reflexes, but it's not guaranteed and depends heavily on the coma's cause, brain function (hypothalamus/pituitary), stress, nutrition, and any underlying brain injury affecting hormonal regulation. While some continue normal cycles, others stop due to stress or hormonal disruption from the brain injury or coma itself. 

What happened to Sarah who was in a coma for 20 years?

For 20 years Sarah lived in a minimally responsive or locked in state of consciousness receiving excellent care that kept her healthy and safe. Little did we know that after many years Sarah had a surprise for everyone.In 2004, Sarah miraculously began speaking.

Why do people go into comas?

People go into comas due to severe brain injury or illness that disrupts the brain's arousal system, often from trauma (like head injury, stroke, lack of oxygen), toxins (drugs, poisons, alcohol), metabolic issues (severe diabetes, kidney/liver failure), infections (meningitis, sepsis), or tumors, leading to prolonged unconsciousness because the brain's "on/off" switch for consciousness gets turned off or overwhelmed. A coma is a serious medical emergency requiring immediate attention.
 

Does being in a coma cause brain damage?

Yes, a coma is often a result of brain damage or injury, and while some people fully recover, others experience permanent brain damage, leading to lifelong disabilities, depending on the coma's cause, severity, and duration, with risks like oxygen deprivation (anoxic injury) or swelling causing further harm. 

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].

What to do if someone won't wake up?

If someone won't wake up, immediately check if they're breathing, call emergency services (like 911), and if they're breathing, place them in the recovery position (on their side with tilted head) to keep their airway open; if not breathing, start CPR if trained, and don't splash water or try to give them anything to drink. Focus on keeping them safe and warm while waiting for medical help to arrive. 

Is a coma the closest thing to death?

Brain death is not the same as coma

Brain death differs from other states of unconsciousness in important ways. For example, coma is similar to deep sleep, except that no amount of external stimuli can prompt the brain to become awake and alert. However, the person is alive and recovery is possible.

Can you cry while in a coma?

Yes, people in a coma or similar states (like vegetative or minimally conscious states) can sometimes cry, laugh, or make facial expressions, but these are often reflexive, automatic responses from lower brain centers, not necessarily a sign of conscious emotional understanding or voluntary action, though they can be distressing for family. While a person in a deep coma is unresponsive, these reflex-like emotional expressions can occur as the brain slowly begins to show reactions, sometimes in minimally conscious states where some awareness might be present.
 

How long are you kept alive in a coma?

Coma patients can be kept alive for days, weeks, months, or even years, though most comas last under a month, evolving into recovery, persistent vegetative states (PVS), or death; survival length depends heavily on the cause (e.g., trauma, stroke) and severity of brain injury, with some rare cases waking after decades, while others transition to long-term unconsciousness requiring supportive care. 

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.

What are the bad signs of a coma?

Coma symptoms

• Unconsciousness (a deep sleep with no response to stimuli)
• Lack of eye response (eyes closed with no response to light or movement)
• Lack of motor response (limbs don't respond or voluntarily move)

What is the final stage of a coma?

A coma doesn't usually last longer than several weeks. People who are unconscious for a longer time might transition to a lasting vegetative state, known as a persistent vegetative state, or brain death.
