Can result from a impact or rapid acceleration/deceleration of the head?

Closed-head injuries are much more common and often cause “diffuse” damage. This type of closed-head injury results when sudden acceleration/deceleration forces to the head cause the surface of the brain to become bruised after impact with the inside of the skull.

What is it called when a traumatic brain injury occurs at the site of impact?

Contusions/Coup-Countrecoup A contusion, or a coup-contrecoup injury, is a bruise of the brain tissue. With this type of injury, flexion-extension or acceleration-deceleration results in the formation of a linear, anterior-posterior lesion at the point of impact.

What is a deceleration brain injury?

Definition. Deceleration injury is a traumatic injury to the brain, typically following an acceleration injury to the brain in a high-speed situation such as a motor vehicle accident or high-impact sports.

What are the two categories of closed head injury?

Of the two, closed head injury (CHI) is far more common. Types of CHI include concussion, contusion, diffuse axonal injury, and intracranial hematoma (epidural hematoma, subdural hematoma, subarachnoid hemorrhage, and intraparenchymal hemorrhage).

How can primary head injury be prevented?

You Can Prevent Traumatic Brain Injury

1. Buckle Up Every Ride – Wear a seat belt every time you drive – or ride – in a motor vehicle.
2. Never drive while under the influence of alcohol or drugs.
3. Wear a helmet, or appropriate headgear, when you or your children:
4. Prevent Older Adult Falls.

What are the two classifications of traumatic brain injury?

Classification as Primary or Secondary injury TBI may be divided into primary injury and secondary injury. Primary injury is induced by mechanical force and occurs at the moment of injury. Secondary injury is not mechanically induced.

What are long term effects of head injuries?

Pathomechanisms felt to be active in the acute and long-term consequences of TBI include excitotoxicity, apoptosis, inflammatory events, seizures, demyelination, white matter pathology, as well as decreased neurogenesis.

What are the long term effects of head trauma?

Mild traumatic brain injury may affect your brain cells temporarily. More-serious traumatic brain injury can result in bruising, torn tissues, bleeding and other physical damage to the brain. These injuries can result in long-term complications or death.
