How do traumatic brain injuries occur. I don't mean like concussions or contusions though. I am trying to write a report on how brain injuries affect personality but i am not sure how a serious brain injury occurs.
the brain for a moment dosent get oxygen sometimes.. there are many ways though
What is traumatic brain injury?
Traumatic brain injury is sudden physical damage to the brain. The damage may be caused by the head forcefully hitting an object such as the dashboard of a car (closed head injury) or by something passing through the skull and piercing the brain, as in a gunshot wound (penetrating head injury). The major causes of head trauma are motor vehicle accidents. Other causes include falls, sports injuries, violent crimes, and child abuse.
The physical, behavioral, or mental changes that may result from head trauma depend on the areas of the brain that are injured. Most injuries cause focal brain damage, damage confined to a small area of the brain. The focal damage is most often at the point where the head hits an object or where an object, such as a bullet, enters the brain.
In addition to focal damage, closed head injuries frequently cause diffuse brain injuries or damage to several other areas of the brain. The diffuse damage occurs when the impact of the injury causes the brain to move back and forth against the inside of the bony skull. The frontal and temporal lobes of the brain, the major speech and language areas, often receive the most damage in this way because they sit in pockets of the skull that allow more room for the brain to shift and sustain injury. Because these major speech and language areas often receive damage, communication difficulties frequently occur following closed head injuries. Other problems may include voice, swallowing, walking, balance, and coordination difficulties, as well as changes in the ability to smell and in memory and cognitive (or thinking) skills.

What is Traumatic Brain Injury?
Brain injuries occur in a variety of different ways, and are more common than most people think. According to the Brain Injury Association, over 50,000 people a year have a serious, traumatic injury to the brain requiring extensive rehabilitation services. Another 700,000 people a year experience mild brain injury, which over half require some degree of rehabilitation services. Traumatic brain injury is the leading cause of death among children and adolescents in the United States.
Brain injuries may occur as a result of motor vehicle accidents, assaults, falls, industrial accidents, sporting accidents, or gunshot wounds. Sometimes injury is caused by internal factors, such as surgery, infection, or lack of oxygen to the brain. A stroke, where there is a blockage or a break in a blood vessel in the brain can produce damage to the brain, and depending on the location and size of the lesion, can result in some of the same problems as a traumatic brain injury.
Because of the complexity of the brain, each person's response to a brain injury can be very different. A person's recovery process will depend on many factors, including the extent of the damage, their pre-injury personality and learning styles, their abilities before the injury, their age at the time of injury, and the amount of time that has passed since the injury.
Perhaps one of the most significant factors in recovery is the support system of the injured person. A brain injury affects not only the person with the injury, but also their family, friends and employer. Since recovery is a long term process, those who have a high degree of support from family, friends, and employer, have a greater chance of continuing to make long term improvements in functioning, even after the formal rehabilitation process.
You have already received some excellent answers. However, I searched Google under the key words "brain trauma" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps a little more. Thanks for asking.
Serious brain injuries, including those that can affect personality, can occur due to several factors. These injuries often involve more severe forms of trauma to the brain than concussions or contusions. Here's an explanation of how serious brain injuries occur:
1. Trauma: The most common cause of serious brain injury is trauma to the head. This can result from various incidents such as falls, motor vehicle accidents, sports-related injuries, physical assaults, or blast injuries in military settings.
2. Impact: When the head experiences a sudden impact, the brain can move inside the skull, resulting in injury. This movement can cause the brain to collide with the skull, leading to damage. The severity of the injury depends on the force of the impact and the specific area of the brain affected.
3. Penetration: In some cases, a foreign object may penetrate the skull and directly injure the brain. Examples include gunshot wounds or sharp objects entering the skull during accidents.
4. Shaking or rotational forces: Severe brain injuries can also occur when the head undergoes rapid shaking or rotational forces. This can happen in situations like high-speed vehicle accidents or when an individual is violently shaken. The rotational forces cause the brain to twist and stretch, resulting in damage to delicate structures within the brain.
It is important to note that serious brain injuries can lead to a wide range of physical, cognitive, and psychological effects, including changes in personality. The specific impact on personality depends on the location and extent of the brain injury, as different areas of the brain are responsible for various aspects of personality.
