  • Hey there, welcome to Life Noggin!

  • Let's say that one day, you get hit in the head with a baseball.

  • Ouch.

  • It hurt but you brush it off.

  • You go home and you go to sleep, but what if that hit did more damage than you thought?

  • What if you never woke up?

  • A coma is a prolonged state of unconsciousness.

  • Someone in a coma is unresponsive to touch, sound, and pain.

  • There's minimal brain activity, and the patient may not be able to swallow or breathe on their own.

  • Usually, comas don't last more than a few weeks, but sometimes people never wake up.

  • The roots of consciousness aren't fully understood, but it's believed that for humans to be awake and conscious, a few things in the brain need to be functioning properly.

  • First, the Reticular Activating System, a group of neurons that dictates wakefulness, needs to be in good shape.

  • Second, both cerebral hemispheres in your brain need to be fully intact.

  • A coma is the result of either a dysfunction of the RAS, or damage to both cerebral hemispheres.

  • This can happen in a number of ways.

  • Traumatic brain injury.

  • A stroke.

  • Drug or alcohol overdose.

  • A brain tumor.

  • A really bad infection.

  • And even diabetes can lead to a coma.

  • But, what's really going on when you're in a coma?

  • In a comatose state, brain activity is minimal, but the brain is still alive and consuming energy from the body.

  • The brain's networks are rerouted.

  • So, normally active areas go quiet and usually dark areas light up with activity.

  • As for the actual experience, different people recall different things.

  • Many remember terrifying visions of torture and death.

  • Others remember happy dreams with loved ones.

  • But some don't remember anything at all about their coma.

  • They remember riding their bike, and then getting hit by a car, and then all of a sudden,

  • they're lying in a hospital bed six months later.

  • I hope they get some free jello out of it at least.

  • Some people say they could hear conversations happening around them when they were in their coma, and there's actually science to back that up!

  • Researchers found that comatose people can hear and that hearing loved ones voices even increases neural activity and speeds recovery.

  • Another study found that some comatose patients can feel pain, even if they don't respond to it.

  • So, being in a coma that was the result of a serious injury could be super painful.

  • And you couldn't even ask for more pain meds.

  • It's hard to know for sure if someone in a coma will wake up, but something commonly used by doctors to monitor a patient's status is the Glasgow Coma Scale.

  • A higher score on this scale means that someone could be more likely to recover.

  • Some people even wake up from their comas fully functional!

  • But others don't.

  • It's not uncommon for a person to wake up from a coma with serious physical or mental disabilities, like amnesia.

  • And some people never wake up at all.

  • A coma can progress into a persistent vegetative state or even locked-in syndrome,

  • when a person is aware of themselves and their surroundings but cannot speak or move.

  • So, have you or anyone you've known woken up from a coma?

  • What was the experience like?

  • If you're comfortable with sharing, let us know in the comment section below.

  • If you enjoyed this video, you're definitely gonna wanna check out our video on what would happen if you never left your bed.

  • The sores usually occur in areas like your tailbone, hips, and shoulder blades.

  • And be warned, they're not pretty.

  • Not even with a little bit of coral blue lipstick.

  • Also, you'll start to get weaker.

  • My name is Blocko.

  • This has been Life Noggin!

  • Don't forget to keep on thinking!

Hey there, welcome to Life Noggin!
