A traumatic brain injury can happen in many different ways. In California personal injury cases, most traumatic brain injuries are caused by external forces. Those forces might be the result of a slip and fall or a car accident. They might also be the result of a battery or assault or a workplace injury. In most cases, the brain injury will fall into one of the following four categories: contusion, concussion, diffuse axonal injury and penetrating injury.
A contusion is usually the result of a direct impact trauma against the head. They usually involve localized bleeding within the brain. In some cases, a contusion has to be removed by a brain surgeon because the blood clots formed by a contusion can result in death in some cases. In certain instances, a contusion will also form on the opposite side of the impact site due to the way the brain collides against the sides of the skull during an impact.
A concussion is the most common variety of traumatic brain injury and it is also the result of direct head trauma. Usually, concussions are the result of a fall, being kicked or punched, or a shooting, shaking or whiplash incident. Loss of consciousness is a common indicator of concussion, but this does not necessarily have to occur. Symptoms include dizziness, confusion or a foggy head.
Diffuse axonal injuries are usually the result of severe shaking. This causes tears in the brain structures and can cause neuro-chemical disruptions. Symptoms of diffuse axonal injury might include motor function loss, memory disruption, olfactory disruption and a lot more.
A penetration injury happens when sharp objects pass through the skull and into the brain. These incidents can be fatal, or they might result in severe, long-term brain damage.
Knowing the types of brain injuries can help those suffering from traumatic brain injury to identify their condition, speak with doctors and get the help they need. It can also help identify their injuries in a legal personal injury context if they are pursuing claims for damages relating to their injuries.
