Types of Traumatic Brain Injury
There are many different types of traumatic brain injuries, which vary based on the individual and the injuries sustained. In all cases, traumatic brain injuries are devastating, both to the victims and their families and loved ones. If you or a loved one has suffered a traumatic brain injury is important to contact an experienced personal injury lawyer to determine whether it is necessary to file a lawsuit for compensation.
Traumatic brain injuries occur when any objects forcefully strikes the head, or when the head forcefully strikes a fixed object. To be considered traumatic the force of impact must be strong enough to both move the brain within the skull casing and cause physical damage to the brain. Traumatic brain injuries can be classified as either open head injuries or closed head injuries. An open head injury involves breaking, cracking or penetration of the skull protecting brain. Closed head injuries to the brain occur without any apparent external fissures, splits or tears.
Additionally, there are three main sub-categories of traumatic brain injuries: diffuse axonal injuries, concussions and contusions.
A diffuse axonal injury occurs when the head is shaken rapidly back and forth, causing the skull to move faster than the brain which then bumps against the inside of the skull and receives bruises, cuts and other damages to the tissue. Diffuse axonal injuries may cause permanent or temporary brain damage, seizures or even death.
Concussions can be minor, moderate or severe and are caused by a violent blow to the head causing the blood vessels of the brain to expand. The symptoms of concussions range from loss of consciousness to dizziness, vomiting or headaches and may not accurately indicate the severity of the injury. As concussions can cause death or brain damage it is important to carefully monitor head injury victims for signs of a concussion.
Contusions are also caused by a violent impact to the head but result in a bruise or cut on the brain itself. Contusions may be fatal or require surgery to correct and prevent.
Traumatic brain injuries can lead to acquired brain injuries which also result from illnesses. Acquired brain injuries affect the brain on a cellular level. Any head trauma or illness that stops the flow of oxygen to the brain causes acquired brain injuries. These are referred to as anoxic brain injuries where there is a complete lack of oxygen and hypoxic brain injuries where there is a partial lack of oxygen.
Any victim of a traumatic brain injury should contact a personal injury lawyer to discuss his or her legal options to seek compensation for damages.
