Can You Live Without A Brain
The brain is the most complex and important organ in the human body. The brain is made of soft nervous tissues which control all body functions. It is the center of the nervous system in all invertebrates and vertebrates. It is located in the head and functions as the coordinating center of intellectual, sensation and the nervous system. So can we live without a brain? Well, lets see if its possible or not.
The brain is divided into two parts: the cerebrum and the cerebellum. The cerebrum controls important functions like our learning ability, emotion, etc. while on the other hand, the cerebellum controls activities such as balance and our muscle movements, etc. But the brain also determines our personality. There are several cases that show that a brain trauma can change someones personality. But back to our main question which is Can we live without a brain?.
To understand this, let us look at a case. In 2014, a 24 years old Chinese woman complained in a hospital about her nausea and dizziness. After a CT scan, the doctors found that the woman was born without a cerebellum but yet lived her life normally without knowing anything about it.
This is because the brains functionality is not just localized to these parts, but rather spread across the brain. The interesting fact is that most of these brain parts have the power to adapt to the functionality of other parts. This phenomenon is popularly called as Neuroplasticity.

What You Need To Know About Brain Oxygen Deprivation
Not all brain injuries involve a blow to the head or lesion. Indeed, your brain can be injured even when nothing comes into contact with your head. Anoxic brain injuries occur when the brain is deprived of oxygen. The aftermath of a lack of oxygen to the brain is largely dependent on the extent of the oxygen deprivation, also known as hypoxia. Some people recover with little to no consequences, while others need years of rehabilitative therapy.
Looking For Other Treatments
You might find information about a treatment that you think is new, or could be offered to you. You should take that information to your specialist. You can talk it through with them and find out if it is relevant for your situation.
Some people might consider going abroad for treatment. It is important to discuss this with your doctor. It might be that a particular treatment is not suitable for you, or it might be available in the UK.
Treatment overseas can be a big commitment. It can be expensive and involve time away from home and family and friends.
You can also consider joining a clinical trial. Go to Cancer Research UKs clinical trials database if you are looking for a trial for brain and spinal cord tumours in the UK. You need to talk to your specialist if there are any trials that you think you might be able to take part in.

What Happens To The Brain When There Is Bleeding Inside The Head
Since the brain cannot store oxygen, it relies upon a series of blood vessels to supply oxygen and nutrients. When a brain hemorrhage occurs, oxygen may no longer be able to reach the brain tissue supplied by these leaky or burst vessels. Pooling of blood from an intracranial hemorrhage or cerebral hemorrhage also puts pressure on the brain and deprives it of oxygen.
When a hemorrhage interrupts blood flow around or inside the brain, depriving it of oxygen for more than three or four minutes, the brain cells die. The affected nerve cells and the related functions they control are damaged as well.
Animals That Dont Have A Brain: Sea Urchins
The sea urchins water vascular system allows it to move quicker.
Sea urchins are pointy, spiky animals, and any beachcomber in their bare feet might discover this in the worst way. Fortunately, outside of South Florida, sea urchins are not poisonous.
The creature has an untold number of legs and controls feeding with its water vascular system. That system changes the amount of pressure and water in its body, allowing it to move faster.
The creatures mouth is beneath it. They expel excrement from the top of their bodies. The sea urchin sits on stones, scraping and feeding on algae. In many ways, this action keeps the ocean clean.
What Is A Hemorrhagic Stroke
A hemorrhagic stroke is when bleeding unexpectedly and abruptly interferes with the brains ability to function. This bleeding can occur within the brain or between the brain and the skull.
Surviving a hemorrhagic stroke depends on the severity of the stroke and how fast the person is able to get treatment. Unfortunately, the majority of people who have a stroke die within a couple of days. About a quarter of survivors are able to live longer than five years, but the recovery process is long and slow.
On the other hand, a minority of people who are able to recover can return to complete or near-complete functioning within 30 days of the stroke.

Diagnostic Tests For Intracerebral Hemorrhage
In the appropriate clinical setting, emergency neurodiagnostic imaging of the brain is required to emergently assess the possibility of bleeding into the brain substance. Once the location of the hemorrhage is identified by history, exam and neuroimaging, other direct diagnostic tests may be pursued as appropriate.

The human brain. It’s the command center of the body. It tells your meat bits where to go, when to breathe, and whether or not to pump blood all around its insides. But do we really need it? Like, need need? It’s nice to have, sure, but what if you could scoop the old gray matter out and be done with it?
There would be benefits, sure. For one thing, you’d be down three pounds of fat instantaneously. You’d never get Smash Mouth stuck in your head again. You could stop worrying about whether the electoral college is good or bad for democracy. But surely there would also be some down sides, like how you’d die and be dead. Still, death is the long term side effect of just about any action. How long could you put it off if your gray matter got sucked out of your nose with a wet vac?
Not long, unsurprisingly.
How Brain Stem Injuries Happen
Brain stem injuries can occur in a variety of ways from a brain stem injury car accident, to slipping and falling. A brain stem injury resulting from a car accident can even occur through whiplash. Slipping and falling can result in blunt force trauma to a persons head, which can lead to the hemorrhaging mentioned above. One of the most common causes of brain stem injury are Las Vegas motorcycle accidents.
If you have been involved in an accident and have suffered an injury to your brain stem, it is vital that you consult with an attorney. Brain stem injuries are often the most devasting injuries a person can suffer because the care the person will need after the accident is expensive and may be needed for the rest of the victims life.
Furthermore, the injury may take away a persons ability to work. Please contact Las Vegas personal injury attorney firm Valiente Mott for a free consultation today if you have been involved in an accident involving an injury to your brain stem.

How Is Intracranial Hemorrhage Treated
Treatment depends on the cause, size, and location of the bleeding. It also depends on your childs overall health. Treatment can include:
Observation. Small amounts of bleeding will reabsorb on their own. This does not need surgery. Your child may need to be observed in the hospital to watch for symptoms of bleeding that gets worse.
Medicines. Medicines may be used to control the bleeding, prevent seizures, and control blood pressure.
Surgery. This may be done to remove trapped blood, treat abnormal blood vessels, remove a tumor, or drain excess fluid in the brain.
Repair of abnormal blood vessels in the brain. This may involve surgery to clip or remove the abnormal blood vessel. Or a catheter can be used to insert glue, a coil, or a balloon into the abnormal blood vessel. This closes it off. This also helps reduce the risk of further bleeding.

How Long Will A Brain
A 13-year-old girl in California continues to be on a ventilator after being declared brain-dead by doctors. Although a brain-dead person is not legally alive, how much of the body will keep on working with the help of technology, and for how long?
Jahi McMath of Oakland, Calif., was declared brain-dead last month after experiencing an extremely rare complication from tonsil surgery. Jahi’s family members have fought to keep their daughter on a ventilator, but a judge has ordered that the machine be turned off next week.
A person is considered brain-dead when he or she no longer has any neurological activity in the brain or brain stem meaning no electrical impulses are being sent between brain cells. Doctors perform a number of tests to determine whether someone is brain-dead, one of which checks whether the individual can initiate his or her own breath, a very primitive reflex carried out by the brain stem, said Dr. Diana Greene-Chandos, an assistant professor of neurological surgery and neurology at Ohio State University Wexner Medical Center. “It’s the last thing to go,” Greene-Chandos said.
In the United States and many other countries, a person is legally dead if he or she permanently loses all brain activity or all breathing and circulatory functions. In Jahi’s case, three doctors have concluded that she is brain-dead.
With just a ventilator, some biological processes including kidney and gastric functions can continue for about a week, Greene-Chandos said.
Diagnosing Brain Stem Death
There are a number of criteria for diagnosing brain stem death.
For a diagnosis of brain stem death to be made:
- a person must be unconscious and fail to respond to outside stimulation
- a person’s heartbeat and breathing can only be maintained using a ventilator
- there must be clear evidence that serious brain damage has occurred and it can’t be cured

What Happens At The End
What happens at the end depends on how your brain tumour develops. Talk to your doctor or specialist nurse. They know your situation and might be able to give you specific information about what might happen.
When brain tumours grow very large, the pressure inside your head increases, causing drowsiness. At first it might be possible to control this by increasing your steroid dose. Eventually the steroids will not be able to reduce the swelling any further.
You might get headaches and sickness. These can often be controlled with painkillers and anti sickness medicine. But you might get drowsier and will need to sleep more often. This can come on quite suddenly or slowly. At this stage, you may be able to lead a relatively normal life. But you might sleep more than you used to.
Some people who have never had seizures , might have some in the last few weeks of their life. Your doctor can start you on anti epileptic medication if this happens.
Gradually you will need to sleep more and more and it may become more difficult to wake you. Eventually, most people slip into unconsciousness. You might be unconscious for a few days or weeks before you die. During this time you will need nursing care to make you comfortable.
Causes Of Cerebral Anoxia And Cerebral Hypoxia
There is a multitude of causes of anoxic and hypoxic brain injuries. According to Headway.org, some of the potential causes of cerebral anoxia include:
- A blockage of blood flow due to a blood clot or stroke
- A severe asthma attack
- Carbon monoxide or smoke inhalation
- Drug overdose or poisoning
- Low blood pressure resulting from disrupted cardiac function or blood loss
- Strangulation or suffocation
- Strangulation or blockage of the airway

Tests To Confirm Brain Death
Although rare, a few things can make it appear as though someone is brain dead.
These include drug overdoses and severe hypothermia, where body temperature drops below 32C.
A number of tests are carried out to check for brain death, such as shining a torch into both eyes to see if they react to the light.
They Had Half Their Brains Removed Here’s What Happened After
TUESDAY, Nov. 19, 2019 — Many people think of their brain as an overstuffed attic. Every square-inch is either crammed with information or working overtime to help the body function properly. So is it even conceivable that a person be normal with just half a brain?
Yes, apparently it is, according to a new analysis that assessed brain health among six adults who had undergone a hemispherectomy as children. The highly invasive surgery, which entails removal or severing of half the brain, had been part of a pediatric epilepsy treatment to reduce seizure risk.
“The people with hemispherectomies that we studied were remarkably high-functioning,” study author Dorit Kliemann said in a statement. “They have intact language skills. When I put them in the scanner, we made small talk, just like the hundreds of other individuals I have scanned,” she explained.
“You can almost forget their condition when you meet them for the first time,” added Kliemann, who is a post-doctoral scholar in cognitive neuroscience at the California Institute of Technology, in Pasadena.
Kliemann and her team noted that the six patients in the study had all struggled with relentless epileptic seizures from a very early age, with one patient initially struck by seizures just minutes after birth.
Now in their 20s and 30s, the six patients agreed to undergo functional MRI brain scans while awake at the Caltech Brain Imaging Center.

Help With Making Plans
It can be helpful to talk through your options with your closest family or friends while you are able. This can help to avoid misunderstanding about what everyone thinks is best. Talking through the options will help everyone to make plans that you all agree on.
You might feel happier knowing that you have made the best decisions for all of you. It can be a very heavy burden on families to decide what to do during a crisis. It might be easier if they know what you would have wanted.
Caring for someone that is dying can be a huge emotional and physical challenge. It’s important that you get all the help and support you need.
Make It Brain On Them Toes
There are lots of ways for your brain to come out of your head: mad science, or trying to knock loose your swimmer’s ear, or being a cartoon character who sees something so scary that your hair and your scalp fly off of your head. In any event, it’ll lead to pretty immediate death.
Technically, in the United States, a person is considered legally dead once they’ve lost all brain function, which is a pretty difficult symptom to avoid if you don’t have a brain in your skull. Physiologically, the only part of you that would keep on ticking would be your heart, but even that would only last for a few seconds at best.
Essentially, every part of you that makes you you would leave along with your little gray cells. Your body would basically be one big amputated limb, completely cut off from your consciousness.
The good news is, scientists are now keeping pig brains alive in jars for up to 36 hours after their removal. So you could always go that route, if you like the total absence of sensation followed by an infinite nothingness.

Can You Live Without A Cerebellum
It may surprise you to learn that yes it is possible to live a full life without a cerebellum.
In 2004, a 24-year-old woman discovered that she was born without a cerebellum. While this temporarily slowed down her development in childhood, it didnt affect her at all as an adult.
Why? Because of neuroplasticity: the brains ability to change and adapt according to its circumstances. It is this ability to learn and adapt that also allows you to exercise your brain to ensure that it stays sharp as you age.
Missing All But The Brain Stem
Trevor Waltrip, born in Louisiana on Christmas Eve in 2001, has defied the odds for 12 years. He lived without any brain at all save the brain stem.
Trevor was born with a rare condition called hydranencephaly, which replaced his neural tissue with cerebrospinal fluid. His brain stem allowed him to breathe and maintain a heartbeat but little more. He was kept on a feeding tube up until last month, when he passed away peacefully.
