How do spinal cord reflexes work below the level of injury?
This can cause further brain damage. Sometimes the initial injury tears blood vessels and blood clots or pooled blood also take up space within the skull. In addition, your blood pressure may drop dangerously low when you have had a brain injury, causing the brain to receive an even lower amount of oxygenated blood.

Loss of sensation or paralysis in extremities below level of injury. The absence of pain does not rule out spinal injury! Cervical injury signs.
What is the most common cause of spinal cord injury?
The most common cause of spinal cord injury is trauma. Spinal cord injury is most common in young, white men. Spinal cord injury can be either complete or incomplete. In complete injuries there is no function below the level of injury. In incomplete injuries there is some function remaining below the level of injury.
Why is the spinal cord so sensitive to injury?
The spinal cord is very sensitive to injury. Unlike other parts of your body, the spinal cord does not have the ability to repair itself if it is damaged. A spinal cord injury occurs when there is damage to the spinal cord either from trauma, loss of its normal blood supply, or compression from tumor or infection.
How long does it take to recover from a spinal cord injury?
The majority of recovery occurs within the first six months after injury. Any remaining loss of function present after 12 months is much more likely to become permanent. Maintaining a positive outlook is extremely important for patients with spinal cord injury.
Where does the spinal cord go?
There are 31 pairs of nerves that leave the spinal cord and go to your arms, legs, chest and abdomen. These nerves allow your brain to give commands to your muscles and cause movements of your arms and legs.
Why are assistive devices important?
The use of assistive devices allows most people with even severe spinal cord injuries to integrate into society and stay productive. Unfortunately, the rate of depression, divorce, and substance abuse are significantly higher in people with spinal cord injury.
What happens if you have an incomplete spinal cord injury?
An injury to the upper portion of the spinal cord in the neck can cause quadriplegia - paralysis of both arms and both legs.
How many bones are in the spinal cord?
The soft, jelly-like spinal cord is protected by the spinal column. The spinal column is made up of 33 bones called vertebrae, each with a circular opening similar to the hole in a donut. The bones are stacked one on top of the other and the spinal cord runs through the hollow channel created by the holes in the stacked bones.
What happens to the brain after a brain stem injury?
After a brain stem injury, the connection between the brain and muscles can become damaged or destroyed. Fortunately, engaging the brain’s neuroplasticity can allow a person to rebuild those neural connections.
What is the most important part of the brain?
Located at the base of the skull directly above the spinal cord, the brain stem is perhaps the most important region of the entire brain. It is responsible for all the functions that keep you alive and aware of your surroundings. The brain stem comprises three distinct sections: Midbrain. At the top of the brain stem rests the midbrain.
How to recover from brain stem damage?
To ensure the best recovery from brain stem damage, you should practice your home exercises every day after therapy. If you struggle with memory problems, have your therapist write you a home exercise sheet to help you remember exactly how to do them.
What is the medulla in the brain?
Medulla. Finally, at the bottom of the brain stem is the medulla .The medulla is in charge of essential life functions, such as breathing, heart rate, and swallowing.
Can you move your eyes with locked in syndrome?
Sometimes, the brain stem is severely damaged and patients cannot move anything except their eyes. Doctors call this condition locked-in syndrome. When a patient has locked-in syndrome, they possess normal intelligence, reasoning skills, and can hear everything going on around them. They just cannot communicate.
What is the brain stem?
The brain stem houses a network of neurons called the reticular activating system (RAS), which helps a person wake up. When the brain stem is damaged, the RAS is compressed and can cause a coma.
Is brain stem damage more debilitating than other brain injuries?
Without a doubt, brain stem injuries are more debilitating than other brain injuries. However, even with brain stem damage, it is possible to improve skills such as swallowing or breathing.
What happens when the spinal cord is damaged?
When the spinal cord is damaged, the message from the brain cannot get through. The spinal nerves below the level of injury get signals, but they are not able to go up the spinal tracts to the brain. Reflex movements can happen, but these are not movements that can be controlled.
How long does spinal shock last?
Spinal shock. This is the temporary loss of all spinal cord reflexes below the level of injury. This could last days to weeks. When spinal shock ends, spasticity or stiffness starts below the level that the spinal cord was injured. Spinal shock cannot be prevented and must resolve on its own.
What are the symptoms of autonomic hyperreflexia?
Conditions below the level of injury that may lead to autonomic hyperreflexia are: 1 Full bladder 2 Constipation or a full bowel 3 Pain 4 Infection 5 Skin breakdown 6 Ingrown toenail 7 Sudden temperature changes in the environment
Why is coughing so weak after SCI?
The muscles (diaphragm, intercostal, and abdominal) needed for breathing and coughing may become weak after an SCI. Coughing is needed to clear the lungs of secretions and bacteria. If a person has a weak cough or cannot clear secretions from their lungs, they will be at higher risk for an infection, such as pneumonia.
Why is autonomic hyperreflexia the highest risk?
Autonomic hyperreflexia happens because nerve messages that used to go up the spinal cord to the brain are blocked.
What is a trach in a ventilator?
If the ventilator is needed for a long time or you have a lot of lung secretions, a person may need a tracheostomy (trach). A trach is a tube placed in the trachea (windpipe). It will make it easier to cough up phlegm and for the nurse to suction the lungs.

The message to the brain may be lost after an injury.#N#There is also no bladder tone when spinal shock is present.
What is the name of the disease that affects the brain and the body?
Autoimmune Diseases. Multiple sclerosis, or MS, is a disease of the central nervous system in which the body’s immune system attacks myelin, the tissue that covers nerves. This interferes with neural communication between the brain and the body.
What is the control center of the body?
A wide range of conditions can affect the brain, spinal cord and nerves that extend throughout the body. The nervous system – compromised of the brain, spinal cord and nerves – is in effect the control center for the body. It reaches from our head to the (nerves in) the tips of our fingers and toes.
Why does my brain swell?
Swelling in the brain may be caused by infection, an autoimmune reaction or some unknown reason. Over time this can irritate and damage brain tissue. Multiple sclerosis and vasculitis are two examples of inflammatory brain disease. A traumatic brain injury may cause inflammation, as well as direct damage to the brain.
How many nerve cells are there in the brain?
The brain comprises about 86 billion nerve cells, and there are more than a trillion connections among brain and nerve cells throughout the body, she says. The brain “is what makes us us. It gives us personality, allows us to talk and feel, gives us emotions.
