Traumatic Brain Injury – Some Causes, Impacts And Treatments

The brain is a highly complex yet very sensitive organ in our bodies. It is normally well protected by a hard bony skull and is suspended in a cushioning liquid. However if subjected to a traumatic brain injury, the results can be devastating. Let’s discuss this situation in further detail.

Some of the more common causes of traumatic brain injury can come from a fall or severe impact to the head. In some cases this impact can actually pierce the skull and directly pierce the brain tissue itself.

This can cause damage to the brain tissue but it can pierce blood vessels and cut off blood flow to critical parts of the brain. And even if the skull is not punctured, significant damage to the brain can occur from an impact.

Although the brain is cushioned and essentially floats inside of the skull, if there is a significant impact it can cause the brain to hit the inside of the skull. When the brain impacts the inside of the skull, it can become swollen at the area of impact.

This swelling and damage to the brain can become worse if not immediately treated. As the swelling increases and the brain enlarges, it has no room inside of the skull and the pressure on the brain gets worse. This causes more swelling and damage.

It is therefore very important that patients who experience traumatic brain injury receive immediate medical attention to relieve the pressure on the brain. There is also need for different surgical and medical techniques to repair broken blood vessels and address other types of damage to the brain.

If a portion of the brain suffers significant injury, it can have devastating results. For example if the section of the brain which controls movement is damaged, it can result in full or partial paralysis. Other areas of the brain which are involved in critical thought, memory, and audio and visual processing can have significant detrimental effects as well.

There are different treatments used for traumatic brain injury. In some cases a patient is taught to have another section of this brain take over for functions which were previously handled by the damaged portion. This can be a long and frustrating process.

However there have been significant improvements in the treatments and techniques used on patients following traumatic brain injury. This can bring very positive results and a much better quality of life to those patients involved.
