What causes brain damage death?
Causes of brain death This can be caused by: cardiac arrest – when the heart stops beating and the brain is starved of oxygen. a heart attack – when the blood supply to the heart is suddenly blocked. a stroke – when the blood supply to the brain is blocked or interrupted.
Which part of a brain injury causes sudden death?
So, Injury to Medulla oblongata can cause sudden death because of hindrance in heart beating and breathing.
What is the longest someone has died and came back to life?
The longest time someone has been cardiac arrest and successfully revived and fully recovered is 17 hours. The record is held by Velma Thomas from West Virginia US.
Has anyone ever survived brain death?
Family members may hold a false hope that the person is just comatose and could wake up with time or treatment. It is important for the medical staff members to fully explain that brain death is final, and that the person is dead and has no chance of ever regaining consciousness again.
What happens if you have a stroke in the medulla oblongata?
A key difference is that with a stroke affecting your medulla, you’ll often have certain symptoms on one side of your body and others on the other side. Some of the most likely symptoms include: Stroke symptoms. Clumsiness or lack of coordination (symptoms of ataxia).
Why does damage to the brainstem cause a coma?
The brain stem houses a network of neurons called the reticular activating system, which is responsible for states of consciousness and your ability to wake up. When the brain stem sustains damage, the reticular activating system can be affected and result in a coma.
Which part of the brain is worse to have a stroke?
The terms Left Brain Stroke and Right Brain Stroke refer to the side of the brain where the obstruction causing the stroke occurs. There is not a worse or better side to have a stroke on as both sides control many important functions, but a more severe stroke will result in amplified effects.
Why is the medulla oblongata so important?
Medulla oblongata function includes a wide range of responsibilities, like: Linking together your cardiovascular system, the system that controls the heart, and your respiratory system, the system that controls breathing. Together they control your heart rate, breathing, and blood pressure.
Can you live without a medulla?
In fact, destruction of the midbrain, pons, or medulla oblongata causes “brain death”, and the unfortunate victim of the injury cannot survive.
How does the medulla oblongata control heart rate?
The medulla oblongata connects directly to the heart through two different pathways: the vagus nerve and the accelerator nerve. The vagus nerve is part of the parasympathetic nervous system and it releases acetylcholine into the heart making it decrease the heart rate.
What happens if you shoot the medulla oblongata?
The kinetic energy transmitted by a bullet entry may indirectly damage the tissues by a shock wave. A bullet impacting on the C2 body without invasion of the spinal canal may cause a sudden death. Concussion injury may be fatal when involving the spinal-medulla oblongata transition region.

What is a stroke in the medulla oblongata?
Let’s break down why damage to this tiny but mighty part of our brain is often fatal.
The Medulla Oblongata: A Vital Control Center
Imagine your brain as a giant, complex network. The medulla oblongata is a small but crucial part of this network, located at the very bottom of your brainstem, connecting the brain to the spinal cord. It’s responsible for controlling a wide range of involuntary functions that keep us alive, like:
Breathing: The medulla oblongata regulates our breathing rate and depth.
Heart rate and blood pressure: It acts as a conductor for our circulatory system, controlling heart rhythm and blood vessel constriction.
Digestion: The medulla oblongata plays a role in the smooth operation of our digestive system, including swallowing, stomach contractions, and bowel movements.
Coughing and sneezing: These reflexes, essential for clearing our airways, are also controlled by the medulla oblongata.
Swallowing: This seemingly simple act is actually quite complex and relies heavily on the medulla oblongata’s coordination.
Why Injury to the Medulla Oblongata is Often Fatal
Now, let’s dive into why damage to this crucial area can be life-threatening.
Disruption of Vital Functions: The medulla oblongata is like a conductor orchestrating a symphony of bodily functions. An injury disrupts this symphony, leading to a cascade of problems. Damage can cause irregular breathing, a rapid or slow heartbeat, and uncontrolled blood pressure fluctuations. This can quickly destabilize the body’s internal environment, putting life at risk.
Loss of Consciousness: Damage to the medulla oblongata can affect the brain’s ability to regulate consciousness, leading to coma or even death.
Inability to Regulate Breathing: The medulla oblongata’s control over breathing is paramount. If it’s injured, we can lose our ability to breathe independently, requiring artificial ventilation to stay alive.
Difficulty Swallowing: A damaged medulla oblongata can lead to aspiration, where food or liquids enter the lungs instead of the stomach. This can cause serious complications like pneumonia.
Causes of Medulla Oblongata Injury
Understanding the causes of injury to this vital region is important:
Stroke: A stroke occurs when a blood clot blocks an artery or a blood vessel ruptures in the brain, depriving brain tissue of oxygen. This can damage the medulla oblongata.
Trauma: A head injury, especially a severe one, can cause damage to the medulla oblongata. This is common in car accidents, falls, and sports-related injuries.
Tumors: Tumors pressing on the medulla oblongata can disrupt its functions and cause life-threatening issues.
Infection: Some infections, particularly those affecting the brain and spinal cord, can spread to the medulla oblongata and damage it.
Prognosis and Treatment
The prognosis for someone with a medulla oblongata injury depends on the severity of the injury and the underlying cause. Immediate medical attention is crucial, and treatment often involves:
Artificial Ventilation: To support breathing when the medulla oblongata is unable to regulate breathing.
Medications: To stabilize blood pressure, heart rate, and other vital functions.
Surgery: To remove tumors or relieve pressure on the medulla oblongata.
Rehabilitation: To help regain lost functions and improve quality of life after recovery.
The outcome for those with medulla oblongata injury can vary greatly. Some people may make a full recovery, while others may experience permanent disabilities. The severity of the injury and the promptness and effectiveness of treatment all play a role in the outcome.
