Types of traumatic brain injuries caused in vehicular accidents include:
Closed Injury
A closed brain injury occurs when there’s an injury to the brain that’s non-penetrating and with no break in the skull.
It is caused by the rapid backward or forward movement and shaking of the brain inside the skull resulting in tearing and bruising of blood vessels and brain tissue.
Closed brain injuries are often caused by slip and falls as well as car accidents.
Open/Penetrating Injury
An open brain injury is much more rare than a closed injury.
It occurs when there’s an open wound and the skull is fractured and the brain exposed, penetrated, and damaged.
An example of this is when the head collides with a sharp object such as a motorcycle brake lever in a motorcycle accident.
Deceleration Injury
It is a traumatic brain injury that occurs when a moving person comes to an abrupt halt and since the brain within the skull still has forward momentum, it hits the skull’s inner surface resulting in injury.
A deceleration injury can occur when a vehicle traveling at a high speed abruptly stops or slows down or when the occupants of the vehicle are propelled from it while it is still moving.
Chemical/Toxic
Exposure to harmful chemicals such as pesticides, carbon monoxide, lead, or other toxic materials may lead to severe injuries and may result in serious medical issues, which include damage to the nervous system and brain.
Exposure to poisonous fumes can actually be fatal in some cases.
Hypoxia
The brain needs a continuous supply of oxygen to function properly.
If that supply is interrupted, it can cause a hypoxic brain injury.
A hypoxic brain injury occurs if the level of oxygen that’s being supplied to the brain is not sufficient enough to maintain normal brain function.
Medical complications such as strokes, infections, and tumors can cause traumatic brain injuries too.
