Can people in coma think?

Yes, many people in a coma or similar unresponsive states can think and have hidden awareness, even if they can't move or talk, with studies showing about a quarter have brain activity showing comprehension (cognitive-motor dissociation), while others might dream vividly or process sounds, indicating deeper conscious experiences than previously thought. Advanced brain scans reveal some patients can follow commands to imagine actions, suggesting they are "in there" but unable to respond externally, highlighting the need for new communication methods.

What does being in coma feel like?

Being in a coma feels like a complete absence of awareness, thought, and sensation, similar to being in a dreamless sleep or blackout, with no sense of time or surroundings; patients are unconscious and unresponsive, though their brains may still process some sounds, and upon waking, many experience confusion and memory gaps, with some reporting feeling sensations like pain or pleasure.
 

Can people in comas think?

Yes, many people in comas can think and have awareness, even if they can't show it; studies reveal about a quarter show brain activity for complex thoughts (like imagining tennis) when asked, suggesting hidden consciousness or "cognitive-motor dissociation," meaning their brain processes information but can't trigger a physical response, essentially being trapped in their minds. While a classic coma means deep unconsciousness, recent findings show some patients experience emotions and even goal-directed thoughts, revealing a spectrum of consciousness beyond just deep sleep or vegetative states. 

How many days can a person survive in coma?

Comas can last from days to weeks while some severe cases have lasted several years. Recovery depends, to a considerable extent, on the original cause of the coma and on the severity of any brain damage.

What to talk about to someone in a coma?

Talk or read to your relative; tell them about your day or what is happening at home, talk about their favourite sports team, speak of familiar names, places, This publication is part of Headway's Effects of brain injury series.

What Happens in the Brain During a Coma?

Can someone in a coma hear people talking?

Comatose patients do not seem to hear or respond. Speaking may not affect their clinical outcome; time spent with them takes time away from other, more "viable" patients. Comatose patients may, however, hear; many have normal brain-stem auditory evoked responses and normal physiologic responses to auditory stimuli.

What is the longest coma someone has woken up from?

The longest widely reported case of someone waking from a coma is Munira Abdulla, a woman from the UAE who awoke in 2018 after being in a coma for 27 years, following a car crash in 1991, though some sources cite nearly 30 years, making her a modern miracle for her significant recovery. Other notable cases include Edwarda O'Bara, who spent 42 years in a state of unconsciousness, and Terry Wallis, who awoke after 19 years, showing varying degrees of consciousness recovery. 

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's the longest person in a coma?

The longest coma on record, according to Guinness World Records, was held by Edwarda O'Bara, who remained in a diabetic coma for approximately 42 years, from 1970 until her death in 2012, though Elaine Esposito (37 years, 1941-1978) was previously recognized, and some reports mention Aruna Shanbaug (40+ years) and footballer Jean-Pierre Adams (39 years) in similarly long states of unconsciousness, often transitioning to a persistent vegetative state.
 

Do people remember being in a coma?

People's memories of being in a coma vary greatly; some recall nothing, while others experience vivid dreams, fragmented memories, sensory snippets (like voices or touch), or even elaborate false realities, often struggling to differentiate them from reality, as the brain tries to fill the memory gap during recovery. While some consciousness may occur, actual memory formation is often limited, with many patients having little to no recollection of the time. 

Can coma patients cry?

Yes, coma patients can cry, but it's often a reflex or part of a minimally conscious state (MCS), not necessarily a conscious emotional response, though some brain activity suggests emotions might be felt; they might cry, laugh, or grimace spontaneously, even without understanding the stimulus, as the brain functions differently in deep unconsciousness versus a partially conscious state. 

Can someone with brain damage hear you?

Usually, coma patients have their eyes closed and cannot see what happens around them. But their ears keep receiving sounds from the environment. In some cases, the brains of coma patients can process sounds, for example the voice of someone speaking to them [2].

What do people dream about in a coma?

People in comas sometimes have incredibly vivid, dream-like experiences, often feeling like alternative realities or long, immersive adventures (like living in Alaska or another world) that blend with trauma, healing, or even mundane activities, sometimes feeling so real they believe them, though some coma patients experience nothing, depending on the coma's depth and brain activity. These experiences can be peaceful or terrifying nightmares, often influenced by their surroundings or medications, and might incorporate elements from their real lives in surreal ways.
 

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.

Are you aware while in a coma?

In a traditional coma, a person appears deeply asleep, unresponsive to pain, sound, or touch, and is generally considered unconscious and unaware. However, recent research using brain scans shows that about one in four patients in seemingly comatose states (disorders of consciousness) have hidden awareness, showing brain activity indicating they can understand commands like imagining playing tennis, even without external signs. So, while most are truly unconscious, some may be experiencing a "living nightmare" of being aware but unable to communicate, highlighting the need for advanced brain monitoring. 

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. 

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. 

What are common coma complications?

Complications of vegetative state coma

• Infections.
• Pneumonia.
• Bed (pressure) sores.
• Contracture (muscles shorten and contort the body).

What are the chances of waking up from a coma?

Chances of waking from a coma vary greatly, depending on the cause (traumatic vs. non-traumatic), severity (Glasgow Coma Scale score), age, and time since injury, with younger people and those with traumatic injury often having better odds, but roughly 30-50% see good recovery, while many face death or long-term disability, especially after several weeks, as most people transition out of coma within a month. 

Can you pass away while in a coma?

Yes, you can die in a coma, as it's a severe medical state with outcomes ranging from recovery to permanent vegetative states or death, often due to complications like infections, blood clots, or the underlying cause (like severe oxygen deprivation or stroke) leading to brain death, which is the irreversible cessation of all brain function.
 

What's the longest someone can sleep?

There's no definitive limit, but prolonged sleep is usually due to medical conditions like Kleine-Levin Syndrome (KLS) or hypersomnia, with cases like a 7-year-old sleeping 11 days or a woman sleeping 19 days reported, though normal healthy sleep usually doesn't exceed 20-30 hours, even after sleep deprivation, as the body needs to catch up.
 

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. After the patients in the true story Awakenings, Shapiro spent the longest time in a coma-like state before waking up. Her story inspired the 1998 movie Forever Love.

How are coma patients 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.
 

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.

What is the shortest amount of time 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.
